What is a solar panel?

A solar panel is an advanced technology-based device that is capable of harnessing solar energy from the sun and converting it into electrical power for regular usage.

Solar panel technology incorporates photovoltaic PV panels that collect energy from sunlight and transform it into electricity for consistent provision of power supply.

Solar Panel Upgrade in Sydney

Do you have a solar power system installed?

Well, chances are that it might be outdated and inefficient, or your power needs may have changed.

Over time, old solar systems lose their efficiency and power generation capabilities. This results in compromised panel performance and insufficient power supply for your day-to-day needs.

That is when you need to consider upgrading your solar power system to a newer one. Such an upgrade enables you to enjoy the perks of an up-to-date solar power system with financial benefits.

When to upgrade your solar panel system?

Before upgrading your solar panels, it is necessary to know when you should go for such an upgrade. Knowing this helps you avoid any needless upgrades that would burden your finances without significant outcomes.

Here, we discuss a few things to help you decide whether you need an upgrade or not.

Physical Wear and Tear

Examine your solar panel properly for any kind of physical wear and tear. Your solar panels may get damaged by harsh weather conditions, winds, or fire incidents. Check your solar panels for cracks, scratches, or fading colors.

Check your wire connections for any kind of damage or breakage. Also, look for bird nests under your panels that might be causing harm to your solar system. Such a physical assessment will help you decide whether your system needs an upgrade, repair, or replacement.

Insufficient Power Generation

Consider the solar power supply and your household demands to decide if there is a need for a system upgrade or not. For this, assess your power needs and check if your solar panel system optimally fulfills them or not.

Your power consumption pattern may change over time. Thus, a solar power system that previously met your power requirements, may no longer do so. Therefore, if you have additional power requirements, system upgrade becomes indispensable to balance power supply and demand.

Performance Decline

Assess the performance of your solar power system to make a decision regarding a solar panel upgrade. Over the time, your solar panel performance may decline for several reasons.

For this purpose, examine the power output of your solar power system. Besides that, you can consider state guidelines for your power output assessment too.

The table demonstrates the average power output of solar systems installed in various cities:

If your solar power system is producing less power output than mentioned in the table, it is an indicator that it needs maintenance or upgrade.

Increased Power Bills

Look for any unexpected or sudden increase in your power bills. This is a strong indicator of performance issues.

However, an increase in your power bills may also result from a change in your power usage pattern. Don’t mistake this with a fault in your solar panels.

Otherwise, if your electricity bills show some rapid surge despite regular power consumption, consider upgrading your solar panel system as needed.

Solar Panel Upgrade Options in Sydney

You might be wondering what options you have when it comes to upgrading your solar panels in Sydney. Well, you can have a wide range of upgrades as per your preferences and requirements.

Here we will discuss 4 ways in which you can upgrade your current solar panel systems.


1. Replace the Current Solar Panel System

The first way to upgrade your current solar panel system is to replace it altogether with a newer system. Solar Panels usually last around 20-30 years on average depending upon side factors. If your solar panel system is much older than that, you can upgrade it by replacing it entirely.

Besides that, if your panel performance has declined too much resulting in low power output, it’s time to replace it with a new one. Physical degradation, extensive microfractures, and panel corrosion also indicate a need for panel replacement.

2. Add Panels to Current System using Original Inverter

Adding more panels to your current system is a highly feasible way to upgrade your solar panels. It allows you to enjoy increased power output without having to install a new inverter or an entirely new solar panel system.

You can avail small-scale technology certificate if your panel power doesn’t exceed 133% of your inverter’s peak power. So for a 1.5 kW inverter, you can have 2kW panels added.

Hence, if you own a big inverter that can support additional panels, adding more panels is a budget-friendly way to upgrade your solar panels and harness more solar energy to increase output.

3. Replace your Inverter with a Bigger one and Add Panels

Another way to upgrade your solar panels is to replace your inverter with a bigger one and add panels to it for increased power output.

You might wonder, why not just add another inverter instead of replacing your inverter entirely. Well, the reason is that it is much easier to add batteries and backup to a single inverter. However, for two separate inverters, it gets much more difficult.

Hence, it is a good option to replace your current inverter with a bigger one in order to sup

4. Add a Separate Solar Panel System to Current One

Another option to upgrade your solar panels is by installing an entirely separate system next to the existing one. This option is particularly feasible if you don’t intend to add batteries and backup to your solar panel systems.

A major benefit of installing a separate solar panel system next to the current one is that it is a relatively easier and faster process to install a new system than integrating it with a previous one. Besides that, you can avail STC rebates on this new system too which would lessen the financial burden related to the new installation.

Tips for Solar Panel Upgrade in Sydney

Now, when you have decided to upgrade your solar panel system, you must consider a few tips to enjoy optimal upgrade results. Considering these tips will help you avoid recurrent upgrades. Moreover, these tips will secure you from any unexpected financial burden during the upgrade process.

How to clean my solar panels?

There are only three ways in which solar panels can be cleaned: cleaning the solar panels yourself, installing a solar panel system that is self-cleaning, or hiring a professional cleaner.

➡️ Although it’s tedious, you can clean your solar panels yourself. All you need is water (a lot of it), soft cloth or a sponge and mild soap. 

For solar panels that are mounted on rooftops, you need a ladder, helmet, safety belts and any other equipment that is required for climbing high and steep roofs. 

The cleaning process is quite simple, where you need to gently rub the solar panels with a wet cloth or sponge while ensuring that you do not scratch or cause damage to them. 

Lastly, rinse with clean water till you are satisfied that they’re sparkling clean and dry off the water.

➡️ Install a solar panel system that is self-cleaning. This method uses very little electrical energy and can clean 90% of dust particles. 

A self-cleaning system cleans the panels automatically and ensures efficient energy output at all times. It saves you time, and you do not have to worry about whether your solar panel is clean.

➡️ Hire professional cleaners.

This is the method that I would recommend, because it is quite affordable and you are guaranteed value for your money. When you hire professional cleaners you do not have to worry about damaging your panel or falling from the rooftop.

1. Performance improvement

A clean solar panel is able to absorb more light, which allows you to enjoy the full potential of your solar panel energy output. Studies show that people who regularly clean their solar panels have a 25% higher efficiency than those who do not.

2. Extended lifespan

If solar panels are not cleaned, they will get damaged and degrade more quickly than their expected lifetime.

3. Safeguarding your warranty

Most solar panel manufacturers and installation companies have stated regular cleaning as a requirement for benefitting from the warranty. 

4. Unreliability of rain water 

Rainwater will certainly wash away dust on your panels, but some dirt like bird droppings and grease can only be cleaned manually using soapy water and a soft brush.

The angle at which the solar panel is mounted determines how well the rain will clean it. In addition, rain is seasonal and you cannot always count on the rains to have a clean solar panel. 

Research shows heavy rainfall of at least 20mm is needed to clean solar panels, but light rainfall can cause dirt and soil to build up on the panels instead.

5. Minimal maintenance and repair

Cleaning is one way to maintain a solar panel, where a frequently cleaned solar panel requires minimal maintenance and repair. While cleaning, you also get to inspect the condition of your panels and detect any issues.

6. Return on investment

Solar panels are quite expensive to install, and you only get a return on investment after several years. However, if your solar panel system is not frequently cleaned you may never get a return on investment due to the constant need for repair and shorter life span.

Effects of not cleaning solar panels

➡️ Low energy output as the light cannot be absorbed well when the panels are dirty and dusty.

➡️ Frequent need for repair which translates to low return on investment.

➡️ Shorter life span, where studies show that solar panels which are not regularly cleaned degrade faster than expected.

➡️ Warranty loss, since you are not guaranteed warranty cover from solar panel companies and manufacturers in case of damage due to a lack of cleaning.

How often should I clean my solar panel in Sydney?

Many solar panel companies and experts recommend that you clean your panels once or twice a year. However, if your solar output is low you can always clean the panel more frequently to improve its efficiency. 

You may also be required to clean your panel more regularly if you are in a location where the levels of dirt and dust are higher.

Ground mounted panels are quite easy to clean, and because of their proximity you can tell when they require some cleaning. 

However, the goal is to keep your panels clean so there is no mandatory time for cleaning them. 

Even those panels that are mounted on the rooftops can be checked regularly for dirt, so you can clean them when needed. However, remembering to do it once or twice a year is good enough.

During the rainy season, there is no need to clean the panels, because most of the dirt gets washed away unless you require thorough cleaning to get rid of dirt such as grease that requires water and soap.

The cost of cleaning solar panels in Sydney

Cleaning solar panels does not have to be expensive, you can do it all yourself if you have the time and ability. 

However, solar panels on rooftops require a professional panel cleaner with the necessary equipment because any related accident can be fatal.

There are various companies in the business of solar panel cleaning in Sydney. Family and friends can recommend companies that are professional yet affordable or better still you can search on the internet for companies with good reviews.

The average cost of cleaning a single solar panel unit is around $3 to $12. However, some companies charge a flat rate that ranges from $150 to $450. The charges could be lower or higher depending on a number of factors :

➡️ Height and steepness on which the solar panel is mounted

Solar panels mounted on steep rooftops are more expensive to clean than those that are mounted on the ground. The higher and steeper the solar panels are mounted, the higher the cost of cleaning.

➡️ Distance from the cleaning company

The cleaning company’s charges also depend on the location of the property the solar panels are on and how accessible it is. We advise you to seek the services of a company that is close to your location.

➡️ Condition of the solar panel

Frequently cleaned solar panels are cheaper to clean than those that have not been cleaned for long.

➡️ Number of solar panel units

The price of cleaning a single unit differs from that of cleaning many solar panels.

➡️ Customer discounts

Most solar panel cleaning companies provide a discount to regular customers who frequently seek their services.

For example, a home that uses electricity to charge a car is very different from another home that only carries a few electrical devices.

A few factors may affect this including the average daily sun hours in your area, the angle, and elevation of your rooftop, the shading from trees or buildings, and the direction your panels face.

A standard 6.6KW system in Sydney can generate around 30kWh per day, which is enough to meet the electricity needs of a typical home.

The best way to determine if solar can meet your needs is by doing a site assessment with a solar professional.

Where are solar panels installed?

Ideally, solar panel systems in Sydney are installed on a north-facing roof.

This is because north-facing roofs receive the most sunlight throughout the day, which means that your panels will generate more electricity.

Solar panels can also be installed on east- or west-facing roofs, but they will not be as effective as north-facing panels.

Can you install panels on a flat roof?

Solar panels can be installed on flat roofs, but they need to be positioned at the right angle to ensure that they receive enough sunlight.

It is also important to make sure that your flat roof can support the weight of the solar panel system.

What is a commercial solar system?

A commercial solar system is an array of solar panels installed on business premises for the purpose of generating electricity for the business. Commercial solar systems are typically larger than residential solar systems since businesses and commercial spaces generally have higher energy requirements.

Are commercial solar systems similar to residential solar systems?

The components that make up a commercial solar system are similar to those of a residential solar system, with one main difference in the size of the system. Commercial solar systems are usually much larger than residential systems,to meet the higher energy needs.

Most residential solar applications are restricted in size by the available roof area to install the system.

Commercial roof structures, on the other hand, do not have this problem, and allow the larger 72-cell panels to be used. This reduces the installation cost and means less energy consumption for each panel.

How do commercial solar systems work?

The solar panels installed on the roof of your commercial facility absorb sunlight and convert this light into DC electricity, which is in turn converted into AC electricity by a solar inverter. The AC electricity is then used to power your business.

You may be eligible for a DISCOUNTED solar system installed on your property. You will need to meet specific criteria and reside in an eligible location.

Am I eligible?

      Why commercial solar doesn’t always require a roof

      Weight can be one of the major factors to determine whether a solar system can be installed on a structure’s roof or not. The weight of the panels and the support system can play a major role in limiting the size of the roof system, and it is very important to prepare and produce a structural engineering certification for the bearing capacity, once the engineering department physically checks the site.

      Careful planning is essential before proceeding with the installation. Flat panel systems are more common than tilted panels, as they are more economical (the tilt frame adds additional costs) and can be easily adjusted based on last minute changes.

      Is a commercial solar system viable option for businesses with low energy budgets?

      olar is a great way to offset energy costs for any business, however, businesses with low energy expenditure may find that solar is not the most cost-effective option.

      Commercial solar systems can be costly to install and maintain, so businesses should carefully study their current and future needs before making a final decision on whether or not to install the system.

      Businesses should also understand the long term benefits of solar, being a renewable source of energy that will eventually pay for itself in the long run.

      How much does it cost to install a commercial solar system in Sydney?

        What are solar panels?

        Solar panels are equipment that convert sunlight into electricity. They are made up of a number of individual solar cells, which are connected together to form a panel.

        what are solar panels

        Solar panels are typically made from silicon, which is a semi-conducting material. When light hits the solar panel, it causes electrons to be knocked loose from the atoms of the silicon. These electrons flow through the solar panel to create an electric current.

        Panels are made up of several different parts, including solar cells, metal frames, glass covers, and wiring. The number of solar cells in a panel can vary, but most panels have between 36 and 72 cells.

        The solar cells are one of the key components of a solar panel, and they are what actually converts sunlight into electricity.

        Modern photovoltaic cells include:

        What are solar panels made from?

        The core materials that are used for the production of solar panels are silicon, Solar cells, metal frames, glass covers, and wiring.

        solar panels components

        Silicon:  Silicon is a semiconducting material that is found in sand. When light hits the silicon, it knocks off electrons away from the atoms of the silicon. These electrons flow through the solar panel to create an electric current.

        Solar Cells:  Solar cells are the structures that convert sunlight into electricity. A solar cell is made up of two layers of silicon. One layer has a positive charge, while the other has a negative charge.

        solar cell diagram

        When sunlight hits the solar cell, it causes the electrons to flow from the negative side to the positive side. This creates an electric current that can be used to power appliances or stored. 

        Metal frames: The metal frame provides the structural support for the solar panel system, and ensures the entire system is held together. 

        The aluminium frames play an important role in protecting the laminated portion of the solar cells while providing a solid structural framework for mounting the panels in place.

        Extruded Aluminium sections are designed for very lightweight stiffness and strong resistance to extreme wind conditions.

        The aluminium frame can be black silver or anodised black and depending on the manufacturer, the corner parts can be screwed, pressed or clamped to accommodate various strengths and stiffness levels.

        solar panel frame

        Glass Cover:  The glass cover protects the solar cells from damage. Glass panels protect PV panels from weather and from impact with hail. The glass is a typically tempered glass with good strength of 3.0-4.0 mm thickness and resists mechanical pressures and extreme heat changes.

        In order to comply with IEC standards, the panel must withstand a hailstone up to 50 km/h (27m/h) in diameter.

        The tempered glass shatters into smaller pieces in the event that accidental or significant damage occurs.

        For improved efficiency and performance, high transmissive glass, which contains a very low iron content, is used by most manufacturers.

        Wiring: The wiring connects the solar cells to each other and to the power source.

        How long do solar panels last?

        solar panel life

        Solar panels are built to last for decades. Most manufacturers offer a 25-year warranty on their products.

        How are solar panels made: The Production Process

        It is fairly simple to produce solar panels professionally, given the few main components of silicon, metal and glass.

        All three components are assembled into solar panels which contribute to the production of renewable energy from renewable materials.

        Solar panels are made using a process called photovoltaic (PV) production. PV production involves creating solar cells, which are then connected together to form a panel.

        First, silicon is purified and melted down into a liquid. It is then poured into moulds called ingots, which give the silicon its shape. Afterwards, the ingots are cut into wafers,or thin pieces of silicon.

        The solar cells are then created by adding impurities to the silicon wafers. The impurities create what are called “p-type” and “n-type” layers in the solar cell. These layers are what allow the solar cell to create an electric current.

        Finally, the solar cells are connected together to form a panel. The panels are then covered with a glass sheet and fixed together within a metal frame.

        Do solar panels degrade with time?

        The most reliable solar system has no moving parts and requires minimal maintenance. The product lifespan is generally anticipated at a 25 year lifespan, with different reasons for the failure.

        Normal cells gradually lose power through light degradation, with a minor light loss per annum. 

        This slow degradation is typically not noticeable and most solar panels can operate with 80% or greater of initial power capacity despite having deteriorated after 20 years.

        The extent of the degradation can be determined by the manufacturer performance warranties and can be found in the warranty section.

        What are the types of solar panels?

        Available solar panels are mono-crystalline, poly-crystalline and thin film type. Thin Film monocrystalline and polycrystalline panels are among the best solar panels available on the market. 

        The differences between mono and polycrystalline solar panels are that monocrystalline solar panels are made from silicon cells with only one crystal whereas polycrystalline panels are made from melting together several silicon crystals.

        Due to their crystalline composition, monocrystalline panel panels are more efficient however more costly than polycrystalline panels.

        monocrystalline solar panel
        polycrystalline solar panel

        How are solar panels assembled and manufactured

        Solar panel assembly can be accomplished by automated robots or a combination of automated robots to position components with a high degree of precision. Manufacturing plants should be highly efficient to ensure that there is no contamination at the assembly line. 

        During the manufacturing stage, panels and cells are monitored and checked with advanced optical sensors to ensure the exact placement of components and that the cell wafers, which are delicate, do not suffer damage during the manufacturing process.

        Are solar panels toxic?

        Despite a few reports of toxic solar panels, there is still no evidence to support this conclusion.

        Claims about toxic solar panels are largely related to obsolete thin-film CdTe solar cells. The trace amount of cadmium in this layer is allowed to dissolve in water. 

        A typical silicon solar panel, however, contains no conductive lead soldered for cell interconnection.

        ☑️ Third step: doping

        Doping is the process of adding impurities to the silicon. This is what gives silicon its electrical properties.

        ☑️ Fourth step: growing crystals

        The silicon ingots are heated to 2,000 degrees Fahrenheit and then cooled to form single crystals.

        ☑️ Fifth step: slicing the crystal

        The single crystals are sliced into thin wafers.

        ☑️ Sixth step: making the solar cells

        The solar cells are made by sandwiching the wafers between two layers of conducting material.

        ☑️ Seventh step: testing

        The solar cells are tested to see if they meet the standards set by the International Electrotechnical Commission (IEC).

        ☑️ Eighth step: packaging

        The solar cells are packaged into solar modules and then into panels.

        Are solar panels made of glass or plastic?

        Solar panels are made of glass. Plastic is only used to cover the solar cells to protect them from the environment.

        What is the cost of producing solar panels?

        The cost of producing solar panels has dropped significantly throughout the years. The cost of silicon has fallen by 99% since 1975. The cost of energy produced from solar panels is now typically cheaper than energy from coal or natural gas.

        Can I make my own solar panels?

        Yes, you can make your own solar panels. However, it is not recommended unless you are a qualified engineer.

        Who is the largest manufacturer of solar panels?

        What kind of solar panel is right for me?

        The type of solar panel that best suits your space depends on a number of factors, including geography, area, application intended and personal needs. There are three main types of solar panels: monocrystalline, polycrystalline, and thin-film.

        Monocrystalline solar panels are made from a single crystal of silicon. They are the most efficient type of solar panel, but they are also the most expensive.

        Polycrystalline solar panels are made from multiple crystals of silicon. They are less efficient than monocrystalline solar panels, but are less expensive.

        Thin-film solar panels are made from a thin layer of semiconductor material. They are the least efficient type of solar panel, and are also the least expensive.

        Is solar panel installation right for you? What should you consider before installing solar panels? 

        things to know before going solar

        Installing solar panels is a great way to save money on your energy bill and help the environment. However, there are a few things you should consider before installing solar panels.

        1. The cost of the solar panels. Solar panels are a significant investment, and you will need to account for the cost of the panels in your budget.

        2. The installation process. Solar panel installation can be a complex process, and you should be prepared to handle the installation, or to find an entity that guarantees the process.

        3. The maintenance of the solar panels. Solar panels require very little maintenance, however, you regularly need to check the panels to make sure that they are free from debris and that the connections are secure. 

        4. The lifespan of the solar panels. Solar panels have a lifespan of 25 years or more, but you will need to factor the cost of replacement into your budget.

        5. The warranty on the solar panels. Good solar panel manufacturers should offer a warranty, however, you will need to verify that the warranty covers the cost of replacement and repair.

        6. The location of the solar panels. Solar panels need to be installed in an area that receives direct sunlight. The location and area will also affect your budget. 

        7. The size of the solar panels. Solar panels are available in a variety of sizes, and the different sizes can directly impact the system production output and your budget.

        Can You recycle solar panels?

        Solar panels are a key tool in the fight against climate change, but what happens to them when they reach the end of their life?

        The good news is that almost all the components of solar panels can be recycled. However, the recycling process requires highly specialized and expensive equipment that very few factories are fit to handle solar panel recycling. 

        This means that most solar panels end up in landfills, taking up valuable space and releasing harmful toxins into the environment. Even though the recycling process is complex and expensive, it is essential and key to look into in order to ensure that solar panels don’t end up causing more harm than good.

        By working on improving recycling infrastructure, solar panels can be properly disposed of at the end of their life, without damaging the environment.

        Your solar panel seller or installer should let you know whether recycling is a good option for you or not. Many solar panel manufacturers have programs that allow users to return or replace solar panels at the end of their life, offering a discount on the price of a new system, 

        Is coal used in the production of solar panels?

        Though it may seem counterintuitive, the production of solar panels actually requires the use of coal. Coal is used as a raw material to produce the chemicals used in the manufacturing process, specifically polyvinyl chloride (PVC).

            What happens to my solar panels during the blackout?

            Your Solar Power system will not operate during a blackout as it is designed to work in conjunction with the grid. However, solar batteries can be added to supplement the system in order to provide emergency backup power during a blackout.

            Solar batteries are charged by your solar panels throughout the day and provide power at night or during blackouts.

            Does my solar system work on sunny days?

            Your Solar Power system will work on sunny days, cloudy days and even rainy days! However, on sunny days they will receive the most sun energy and thus will generate more power on a sunny day than on a cloudy day. 

            Do the solar energy systems work during the night?

            Your Solar Power system will not work at night, as they rely on the sun to generate power.

            However, adding solar batteries to the solar system will allow you to store the excess energy generated throughout the day, which can be used during the night. 

            Can I install solar panels on a flat roof?

            Solar panels can be installed on both flat and pitched roofs. The difference is that the installation on flat roofs will require brackets to incline the panels at a specific angle towards the sun. 

            On the other hand, solar panels on a pitched roof will require specialized clamps that attach to the tiles or metal sheeting.

            Laying the panels flat on a flat roof could actually generate some power, however since the sun’s rays aren’t hitting the panels at a correct angle, the produced power will be far less than the optimum power expected. 

            Is there any financial return for a solar system in Sydney?

            Research has shown that homes in Sydney can enjoy a financial return of up to $2,704 per year after installing solar panels.

            The main reason for this return is the presence of ample sunshine throughout the city, which will allow users not only to save money by reducing electricity bills, but also to exponentially increase their savings in peak times and seasons when the energy costs skyrocket, such as during summer months. All these financial savings are made while eliminating emissions and harmful chemicals from the environment.

              Frequently Asked Questions


              How much do solar panels for my home cost?

              Solar panels are a popular alternative to traditional forms of energy, but they can also be a significant financial investment. The cost of solar panels varies greatly depending on a number of factors, including wattage, size, operation and convenience.

              Solar system prices depend on the number and size of panels as well as the wattage they produce. As a result, it is important to consult with a solar expert to get an accurate price estimate before making a final decision.

              With careful planning and analysis, however, solar panels can be a great way to save money on your energy bills and minimize your environmental impact.

              How many solar panels do I need for my home?

              When considering solar energy for your home, one of the first steps to make is to assess how much power you typically use.

              Your past power bills can give you a good idea about your household’s operation, as they provide a record of your actual usage. It’s also important to look for any patterns in your usage, as this can help you anticipate future needs.

              For example, if your electricity consumption has been steadily increasing over time, it’s likely that you’ll need more solar panels than someone whose consumption remains relatively consistent.

              Once you have an estimate of you power requirements, you can evaluate how many solar panels you’ll need to meet that amount of power. This computation will also take into account factors like the tilt and orientation of your roof, as well as the amount of sunlight it receives.

              With this information, our energy efficiency experts can help you determine the best way to integrate solar energy into your home.

              What will happen to my solar panels after 20 years?

              When considering solar panels for your home, it’s important to keep in mind the long-term investment that you’re making.

              PV solar panels have a warranty of 20-25 years, which is upheld by the solar panel manufacturer’s guarantee.

              Solar panels degrade at a pace of 1% every year, but this is offset by the guarantee, which ensures 90% production in the initial ten years and 80% by year 25 or 30.

              So, even after 20 years, your solar panel will still be over 80% efficient. In other words, you can trust that your solar panel will continue to provide energy for your home for many years to come.

              How does solar impact my property values?

              If you’re considering installing a solar system, you may be wondering if it will add to the value of your home. The short answer is yes – in most cases, installing solar panels will increase the resale value of your property.

              Studies have shown that homes with solar energy systems sell for more than homes without them. However, your property value will only increase if you own, rather than lease, your solar panel system.

              In most parts of the country, having a solar system will actually increase your property value more than a kitchen renovation.

              So if you’re thinking of selling your home in the future, installing a solar system is a smart investment. Not to mention, it’s also good for the environment!

              Can I go off-grid with solar panels?

              Solar panels are a popular choice for homeowners who want to reduce their dependence on fossil fuels and save money on their energy bills.

              However, it is important to understand that when you install solar panels, you will still be connected to the grid.

              This allows you to draw power from the grid when your system is not generating all the power you need, and also to feed power into the grid when producing more than you use. 

              In order to go completely off-grid, your solar energy system should include battery storage with enough capacity to store the energy produced, in order to meet the demand while the system is not generating any energy. While this type of system gives complete energy independence, it costs significantly more than standard systems and is usually unnecessary for most homeowners. 

              Therefore, if you are considering solar panels for your home, make sure to take into account the ongoing costs of being connected to the grid.

              Trina solar panel review in detail

              Trina Solar is one of the best manufacturers of solar panels in the world. 

              The company was created in 1997 by Gao Jifan. During those years, Trina was just a PV enterprise in China. However, today it is one of the largest manufacturers of solar panels in the world.

              Trina Solar greatly associates its success with quality production and customer satisfaction. 

              One of its main markets is in Australia, where the Australian Solar industry is flourishing and thriving thanks to Trina.

              Types of Trina Solar Panels

              In a layman’s language, a solar panel is a piece of technology used to convert light to electricity. 

              These panels contain solar cells that collect and convert light energy. The solar cells are mostly made from silicon, boron, and phosphorus.

              Technically speaking, there are four major types of solar panels. There are monocrystalline, polycrystalline, Thin-film, and PERC solar panels.

              Trina Solar manufactures all these types of solar panels. Moreover, it continuously incorporates the latest tech into its solar panels. Some of Trina’s most famous solar panels are the following:

              Honey Series

              The Honey solar panel meaning “sweet,” is one of the best solar panels in the market. Indeed its sweetness is widely felt as it incredibly lowers energy costs. 

              Trina Solar offers 25yrs warranty on these solar panels.

              The Honey series can be monocrystalline, PERC, or polycrystalline, depending on your preference. 

              The efficiency level of these solar panels is fantastic. Honey solar panels are ideal for limited spaces, residential, and even commercial areas.

              Now available is the new Trina Honey M range and Honey M black, with sizes ranging from 330W to 380W. 

              They are available in white and black backsheets instead of the standard silver. These solar panels have 20.7% efficiency, which is superb.

              They primarily utilize half-cut and multi-busbar technology (MBB). 

              Trina Solar is shifting mostly to MBB energy due to its numerous benefits. These benefits include increased efficiency, reliability, reduced cell temperature, and more.

              Honey series is the most popular solar panel utilized in Australia. Its design fits perfectly with the Australian climate. The Honey series solar panel is ranked best by PV Evolution Labs testing.

                Duomax Series

                Duomax solar panels have been created using two technologies: bifacial cells and dual glass technology. Moreover, these solar panels come without aluminum framing, which leads to less dirt accumulation.

                Interestingly, the Duomax solar panel can absorb light from the back face. That brings about up to 25% more energy. The dual glass tech also increases the lifespan of this solar panel. However, Duomax solar panels are pretty heavy compared to traditional solar panels.

                Why should you buy Trina Solar panels?

                People purchase solar panels mainly for water and pool heating or electricity purposes. Before purchasing solar panels, there are a few factors to consider. 

                These factors are vital as they can determine the performance of the solar panel.


                Location is an essential aspect to consider when purchasing solar panels. 

                Where will you place the solar panel? If it’s on the roof, can your roof support the solar panel? Some rooftops may be too small or require repair. Whatever the case, make sure the rooftop is suitable.

                The location where you choose to place your solar panel will affect the light it receives. 

                In addition, the angle or tilt of the solar panels affects efficiency too. Countries in the southern hemisphere should place their solar panels facing north.

                In Australia, for example, solar panels placed in the east or west are 10% to 20% less effective. On the other hand, those set facing north at an angle of 30 degrees are more effective. 

                This is because the sun moves towards the north. Therefore the solar panels will be able to absorb maximum light energy.

                It would be best to try to place the solar panels away from tall buildings and trees. Such objects might hinder the flow of light to the solar panels as light travels in a straight line.

                Lucky for us, Trina Solar Panels are designed to fit any location regardless of the conditions or climate in your area.

                Type of Solar Panel

                As mentioned earlier, there are various types of solar panels. 

                Each of these solar panels has its own merits and disadvantages. Also, each is suitable for specific purposes, whether residential or commercial.

                Monocrystalline solar panels, also referred to as single-crystal panels, are the purest solar panels. This is because they are made from pure single silicon.

                They are good in places that require a high amount of energy and are suitable for residential and commercial purposes.

                On the other hand, we have Polycrystalline panels, otherwise known as multicrystalline. These solar panels are made from different pieces of melted silicon. 

                The melted silicon is later molded into squares or rectangles to create polycrystalline. These solar panels work well with self-powered devices.

                Passivated Emitter and Rear Cell Panels (PERC) are an advancement of the monocrystalline ones. Compared to traditional monocrystalline, they are better and more efficient. 

                They have improved absorption power, facilitate the proper flow of electrons and more…Moreover, PERC solar panels are terrific for limited spaces.

                As the name suggests, Thin-Film solar panels are thin in terms of their layers. This makes them highly flexible. They can be made from different materials like Amorphous Silicon (a-Si), Cadmium telluride (CdTe) and Copper indium gallium diselenide (CIGS). Thin-Film solar panels are mainly utilized in satellites and spacecraft.

                In Australia, most individuals purchase monocrystalline or polycrystalline solar panels. The most popular is the Trina Honey series, as its design blends in perfectly. It is wise to select a type of solar panel that best fits your needs and purposes.


                Durability simply refers to the lifespan of the solar panel. You definitely don’t want a solar panel with a short lifespan. That’s why it is vital to buy solar panels from a certified manufacturer. Trina Solar guarantees you quality and value for your money.

                Before getting a solar panel check out the factors likely to cause wear and tear. For example, Australia is known to be super windy. So, get a solar panel that can tolerate wind pressure and hailstorms.

                Trina solar panels have undergone over 30 house tests and have tolerated extreme temperatures. They also have a coating that makes them more resistant to hailstones, snow etc.

                Moreover, before these panels are released for sale, they must pass through SPC. Statistical process control (SPC) is a process designed to identify and solve any potential problems.


                Naturally, before making any purchase, everything must be budgeted. 

                Several costs have to be considered when purchasing solar panels. There is the cost of purchase, installation, and even maintenance.

                You should find a solar panel that matches your budget. The good news is Trina Solar panels offer a wide variety of solar panels, so you can always find a solar panel that meets your budget and preferences.


                You should consider the warranty period before getting a solar panel. Furthermore, always select the product that has the most prolonged warranty period.

                Trina is one of the companies that provide the most extended warranties. 

                They sincerely value their customers, which is why they even have a performance warranty to guarantee that your solar panel will perform at a certain percentage. If not, you can have the solar panel replaced.


                Efficiency is another major issue to consider before you purchase a solar panel. 

                Efficiency means not only maximum productivity but also minimum waste. In Australia, there are numerous solar panels to choose from.

                While it’s wonderful to have variety, it makes selecting an efficient solar panel tricky. So how do you choose an efficient solar panel? When selecting a solar panel, check its efficiency. 

                An efficient solar panel should have efficiency of 15% and above.

                Monocrystalline solar panels are known to have an efficiency of over 20%. 

                Polycrystalline has 15 to 17% efficiency, while PERC can have over 20% efficiency. PERC solar panels tend to have high efficiency due to their passivation layer.

                Trina Solar panels are proven to have above 20% efficiency, which indicates that the productivity of these solar panels is high-end.

                Trina solar panel: Conclusion

                Trina Solar is the go-to solar panel company. 

                Their packages and offers are just on another level.

                They are ranked as Tier one solar panel manufacturers by Bloomberg, an institution that checks on the bankability of solar panel manufacturers. This refers to whether a conventional bank would lend money to the solar manufacturer.

                Trina Solar being Tier one, shows that it has sound financial recordings. Did you know Trina Solar is also listed on the Shanghai stock market?

                In addition, it was one of the best performers in the LID + LETID test. Trina solar panels are, without a doubt, excellent, and their good quality is evident. 

                Moreover, the company always supports and brings forth new technology like N-type cells, Multi-busbars (MBB) and even advanced bi-facial cells.

                Australia is ranked 6th in the world among solar users after Japan, Germany, India, Italy, and United Kingdom. It is an open secret that government agencies and stakeholders in New South Wales [NSW] are doing all they can to actualize almost 100% solar power usage nationally.

                In Australia, anyone who purchases a solar panel system is eligible to receive the government of New South Wales (NSW)’s a solar rebate which can cut the cost by up to 33%. 

                This has been in effect since the beginning of 2017 and will end in the year 2030.

                For foreigners who are not acquainted with the concept of the NSW government solar rebate, this is a curious fact.

                More enticing is the fact that one is liable to benefit not only from a long-lasting solar system but a warranty that extends as long as a decade!

                GET SOLAR REBATES

                You may be eligible for a DISCOUNTED solar system installed on your home. You will need to meet specific criteria and reside in an eligible location.

                Am I eligible?

                  What are solar rebates?

                  The federal government under a program called the Small-Scale Renewable Energy Scheme (SRES) offers loans and other financial conveniences to eligible house-owners in approved local government areas to install renewable energy systems such as rooftop solar, solar water heaters, and heat pumps.

                  Instead of the traditional systems, solar hot water systems make use of the sun to generate power to heat water.

                  The installment is to be done by an approved dealer, who must have earlier given a quotation to the house-owner.

                  The process comes with some discount that ranges from 20 to 33% for the house-owners through STC’s; though this depends on the size of the panel, location, agreed price, and market conditions.

                  Small-Scale technology certificates ( STC’S)

                  For the record, the NSW government solar rebate consists of ‘small-scale technology certificates’ (STCs) and stands at $825 per kWh up to a maximum of 30kWh.

                  STC’s are the way the two parties render a commodity or service in exchange for money after the installation of solar systems.

                  House-owners can lay a claim to STC’s whenever they install any of the above-listed equipment, and this is determined by the amount of electricity generated.

                  How To Calculate STC

                  Calculating the number of STC’s you are entitled to and ultimately your solar rebate is quite easy.

                  kW solar panels x 11 (11-year deeming period) x zone rating (above table 1.2) x Spot STC price

                  Example: Ana lives in Chester Hill 2162 NSW and wants to install a 6kw system.

                  Calculation: 6 x 11 x 1.382 = 74 STC

                  74 x $38.50 = $2,849 rebate.

                  People call it ‘Low-income Households trial scheme’ and ‘Small-scale Renewable Energy Scheme’ too. NSW government stated that the scheme could save households up to $600 per year.

                  New South Wales Government made this effort to help house-owners access interest-free loans, thereby creating an enabling environment in which everyone uses solar energy. 

                  NSW is geared towards the achievement of ‘net zero emissions’ by the year 2050.

                  For instance, if anyone can get clean and renewable energy, this would undoubtedly cut power bills.

                  It is of immense importance that this is not limited to solar-only options, but it is a pilot and is available in limited regions.

                  Most people don’t see the need for the usage of solar systems, and this is understandable. 

                  Residents are encouraged to use the Solar Battery Calculator (SBC) to decide if they would financially benefit from the usage, or add a battery to the existing solar system.

                  SBC also helps to know how much a house-owner is qualified for. It is calculated as follows: The size of the solar system x the postal code rating x the Deeming Period. 

                  If the deeming period is short, you will get less STCs. For Example, in 2018, the deeming period was 13 years, but in 2019 it was changed to 12 years.

                  Among the questions asked in SBC are ‘roughly what was the last cost of your quarterly electricity bill’, ‘how does your household use electricity, what type of tariff do you use’, ‘would you be interested in joining a virtual power plant’, etc?

                  Eligibility lies in living within the approved local government areas, which are Bathurst, Blayney, City of Blue Mountains, Cabonne, City of Central Coast, City of Cessnock, Dungog, City of Hawkesbury, Kempsey, City of Lake Macquarie, City of Lithgow, City of Maitland, Mid-coast, Mid-Western, Muswellbrook, City of Newscastle, Oberon, City of Orange, Port Macquarie-Hastings, Port Stephens, Singleton, Tamworth, Upper Hunter Shire, and Walcha.

                  Furthermore, one has to meet the loan criteria, have an income of at least $180,000 per annum, own a house, and have the authority to install the solar system.

                  To apply, the interested house-owners should contact the approved suppliers to scrutinize needs and organize several financial quotations.

                  They would then be given what is called a ‘quote record number’. 

                  It is created for house-owners whenever an approved supplier gives them financial quotations/statements after they meet the requirements.

                  Upon approval, the chosen supplier will contact the homeowner to arrange the installation procedures.

                  Approved Suppliers are also known as ACPs (Accredited Certificate Providers),  and they are regulated by The Independent Pricing and Regulatory Tribunal (IPART).

                  An exception is Family Energy Rebate, which is a government scheme that provides $180 in 12 months for the interested persons “that do not hold a DHS Concession Card or Health Care Card; or, $285 a year to eligible customers that hold a DHS Concession Card or Health Care and also qualify for the Low Income Household Rebate.”

                  It is also designed to cater to the energy bill of NSW family households with dependent children.

                  It is noteworthy to observe the state of solar system rebate in Victoria, because it is the sole state that offers panels and inverters alongside solar batteries. 

                  It is estimated that house-owners who are eligible get up to 50%; though this is subject to sizes of their choice.

                  A source says the scheme helps the average household to save at least $ 160 – 400 annum.

                    Solar system rebates in QLD

                    Queensland made the solar system rebates juicy by giving out interest-free loans and grants in the installation and storage of solar panels. 

                    Application for the solar grants and loans, which was scheduled to close down on the 30th of June, 2019 – or if the funding is exhausted- has long been extended.

                    Today, it is speculated that the typical rebate offers a third of the price, but it is based on several factors which include the prospective customer’s choice of size, location, and the market price of STC’s

                    Am I Eligible for the Solar Power Rebate in QLD?

                    The government of Queensland arouses lots of people’s interest, and it is not out of context to say almost all residents are likely eligible for the solar rebate.

                    Unlike other schemes, almost everyone is eligible. Make sure to install your solar system with a Clean Energy Council Accredited Installer (like Captain Green Solar!), in Queensland. 

                    The solar panels and inverters you use must also be approved by the CEC and adhere to Australian and New Zealand criteria.

                    Conditions, as outlined by the CEC, are:

                    What About STC’s in QLD?

                    The Solar Power Rebate QLD offers Small-scale Technology Certificates (STCs) as a component of Queensland’s Small-scale Renewable Scheme. 

                    The scheme offers all residents arebate on solar power services and installation regardless of the solar system you choose to install. 

                    You can obtain certificates that can be traded on the open market or given to your solar installer, so that you can receive lower installation costs.

                    While you can choose to trade STCs yourself, it may be easier if you assign the right to claim over to your solar power installer at the point of sale. 

                    They can give you a discount upfront.

                    The price of an STC depends on the cost of carbon. Costs are subject to fluctuation due to supply and demand. 

                    However, on average, the prices often sit between the $35 and $40 mark

                    Why should you clean your solar panels?

                    Is It Necessary? How Often?

                    The first thing that comes to mind when answering this question is that it is critical to keep your solar panels clean in order to conserve their efficiency.

                    It is recommended that, after installing solar panels, you brush them with a soft brush to remove any tree leaves or dust that may have accumulated on them during the installation process; otherwise your solar panels will stop working efficiently.

                    Also Read: What is the cost of solar panel installation?

                    Overall, similar to cleaning other devices, it can be beneficial to pay attention to the condition of your solar panels. We recommend that you perform the cleaning process once every six months or so.

                    This can significantly increase your panels’ power generation capacity. Ordinary yearly breakdowns attributed to this factor are estimated somewhere in the range of 2% and 5% regularly.

                    However, by collecting dirt on the PV framework, this can increase after some time. That is why it is critical to understand how frequently and when to clean your sunlight-based boards.

                    How does cleaning improve the efficiency of solar panels?

                    The accumulation of dust from the outdoor environment on solar panels is natural, but it can reduce their performance.

                    Average solar panels have an efficiency rating of 18%–25%, but if they are dirty, this rating may decrease. Solar panels require cleaning to achieve their maximum efficiency ratings.

                    Solar panels generate 18 to 25% of their energy from the sun on average, depending on the quality of the solar cell. However, when they become dirty, the amount of light that they convert into electricity decreases.

                    To keep them efficient, you must clean your solar panel systems regularly. The frequency with which a solar system should be cleaned is determined by several factors. This includes ensuring that there is no pollen or dander on the panel if you have trees.

                    If birds are actively flying around your house, you will need to clean the obvious bird droppings.

                    Because of the upward angle of the solar panels, they are more prone to bird droppings and a buildup of general dust and dirt that does not wash away with rain.

                    This reduces the amount of light that strikes the panel and thus its output.

                    Can I clean the solar panel myself?

                    If you decide to clean your solar panel, you have two options: hire a professional or do it yourself. Many solar companies will provide you with this type of service.

                    The best way to clean your solar panel is to hire an expert or a maintenance engineer who can handle your entire system, not just cleaning.

                    If you insist on cleaning your panels yourself, you’ll usually have everything you need at home. In most cases, all you’ll need is a hose and some soap, and you’ll be good to go.

                    You can use a soft rag/soft mop or a non-abrasive sponge. Clean solar panels while they are damp to ensure that any dirt or adhered residue is easily wiped away.

                    When cleaning solar panels, it’s important to avoid using harsh materials that could damage them. You can also clean them with a robotic system that runs on the frame.

                    Another option is to install sprinklers that will clean the panels.

                    How frequently should solar panels be cleaned?

                    Most solar experts recommend that you clean your panels thoroughly at least once a year. 

                    Because most solar panels stand tilted at an angle on the roof, dust, leaves, and other pollutants frequently slide off the panels. 

                    Dirt, bird droppings, and other debris, on the other hand, can cause a build-up on the solar panels, reducing their efficiency by a significant margin. 

                    Cleaning the solar panels will ensure that they are operating at peak efficiency. Flat solar panels need cleaning more frequently than tilted solar panels. 

                    The reason for this is that dust, dirt, pollen, leaves, and other debris do not easily slide off the flat solar panels.

                      What happens if you don’t clean your solar panels?

                      If solar panels are not cleaned, they will degrade more quickly. This is because dirt on the panel’s surface reduces its transparency as well as its ability to absorb energy.

                      UV light can cause chemical reactions in the dirt on solar panels, resulting in corrosive substances that vaporize metal panels, causing component damage.

                      The best way to keep your solar power system running at peak capacity is to have professionals handle all maintenance tasks, including regular inspections and cleaning.

                      Cleaning solar panels: Things to know before you start cleaning

                      Also Read: How to buy the best solar panel

                      Methods of solar panel cleaning

                      1. Simple process:

                      2. Manual

                      manual solar panel cleaning

                      ➡ Develop a reasonable cleaning schedule based on local conditions to ensure a scientific and efficient cleaning plan that meets power generation efficiency requirements.

                      ➡ The cleaning must be thorough; otherwise, serious consequences such as the “hot spot effect” may occur.

                      Under normal lighting conditions, the solar panels in the corners that are unclean will transition from generating units to power-consuming units, and the shaded photovoltaic cells will become load resistors that do not generate electricity, consuming the electricity generated by the connected batteries, i.e., heating.

                      This process will accelerate the aging of the battery board, reduce output, and, in extreme cases, cause a fire.

                      ➡ Use a specialized cleaning fluid. Some users clean and disinfect the solar panels with regular tap water or well water.
                      Because water contains many impurities, it will adhere to the surface glass of the solar panels, reducing the solar power generation efficiency.

                      Experiments have shown that rinsing solar panels with tap water reduces power generation efficiency by more than 1.8 percent compared to using a special cleaning solution.

                      ➡ Choose the appropriate cleaning tools and methods to extend battery life. The surface of the solar panel battery is made of high-strength tempered glass, which is prone to wear.

                      The solar panel has a service life of more than 20 years. It is typically cleaned once or twice a year to ensure normal power generation.

                      It is easy to cause the surface of the battery to wear if the methods and tools used are not appropriate. This will affect the power generation capacity and life of the battery panel.

                      ➡ Resolve the problem of solar photovoltaic power plants’ cleaning during the winter and snow season. Water cannot be used to clean battery components during the winter and snow seasons.

                      Condensation and icing on battery panels continue to be a problem in some seasons.

                      For example, you can use removal equipment like dew removal equipment, deicing equipment, and waterless cleaning.

                      3. Cleaning with Power washing

                      power wash solar panel cleaning

                      High-pressure water flushing is the process of cleaning a solar panel by spraying it with water from a nozzle.

                      Power washing with plain water is the best method because it is quick and effective, but it is risky.

                      The glass/metal seal on the front of the modules cannot withstand the potential force from power washing, and forcing water into the module will almost certainly destroy it and void the warranty.

                      However, I believe that with caution, power washing can be effective.

                      When the modules are hot, do not spray them with water. The glass may break, and even if it does not, you may cause damage to the metal/glass.

                      You can use a gentle stream of water to wash away dirt that has accumulated on solar panels. Pressured water, on the other hand, can cause damage to your panel.

                      4. Photovoltaic cleaning machine powered by electricity:

                      Solar photovoltaic panel cleaning technology can significantly improve the efficiency of electricity generated as well as the solar panels’ durability.

                      There are various cleaning methods, including electrostatic cleaning, super hyperbolic coating methods, mechanical methods, microcontroller-based automatic cleaning methods, self-cleaning nanodomes, and dust particle characteristics.

                      5. Automatic cleaning:

                      Technology now allows the automatic cleaning of solar panels without the use of water or labor. The system takes advantage of the fact that most dust particles have an electric charge, which is especially useful in dry environments. The entire panel vibrates to shake dust loose.

                      6. Robotics

                      Robotics technology allows companies like Italy’s Washpanel to produce automatic and semi-automatic solar panel cleaning robots. 

                      It offers semi-automatic portable robots for panels installed on carports, greenhouses, and shed roofs.

                      It also provides fixed roof robots for large installations in dusty environments that require regular cleaning.
