Solar power production in Australia has become more crucial in the face of rising electricity costs and high solar radiation.
Solar panel systems with this size and power that can be installed on a residential or commercial building are necessary for evaluating usage.
This article is centered on the rather popular size of “3KW solar panels,” which is the most common solar panel size. It will describe the main features of such a system like the number of panels required and the output power.
A 3KW solar panel system: what is it?
A few photovoltaic panels, an inverter, mounting hardware, and other parts that convert sunlight into electrical energy are often found in a 3KW off-grid solar panel installation.
It is named 3-Kilowatts Solar Panel System, because its photovoltaic system output can reach up to 3000 watts.
Different solar panels can be combined to make a 3KW Solar System.
This type of unit will work best for an average family with a medium socio-economic status. In terms of benefits, we can mention savings on electricity bills, reduction of environmental pollution, and the possibility of state support if available.
Size of a 3KW Solar Panel
Solar power panels are designed to convert solar radiation into electrical energy. Typically, solar panels are around 1.6 meters by 1 meter. In order to operate a 3KW system, 3 kilowatt panels must be purchased.
The average number of panels needed would be 8-10 panels in the 3KW model, as each panel generates on average 300-350 watts.
The area required can be between 14 and 20 square meters covering the roof, if the panels are adequately placed and their efficiency is optimal.
How Many Panels in a 3KW Solar System?
Solar systems generate a certain number of kilowatts per hour of electricity depending on the module types used and the total number of needed modules.
The higher the wattage of each panel, the fewer panels will be necessary. For instance, if you are required to utilize 300-watt panels to make a 3KW system, you will need 10 (3000 watts divided by 300 watts per panel).
On the other hand, when using 350-watt high-end panels, probably only about 9 panels would be needed. This kind of system allows the homeowner to customize your panels depending on the size and budget constraints to be placed on the roof.
Output of a 3KW Solar System
Exact electric output from a Solar Power System is nearly impossible to forecast due to various reasons like location, tilt, and weather conditions.
In Australia, you could generate in the vicinity of 12 to 14 kilowatt-hours (kWh) by having the right positioning of your 3KW grid-tied system. It is enough for homeowners to live comfortably in covered homes.
3KW Solar Panel System Expected Prices
Now that you have some information on the 3KW Solar Panel, you must be asking yourself, what budget do I need for a 3KW Solar Panel?
It is not that high, where a budget of $3000 to $5500 can allow you buy anything from a lower-end system ($3000) to a standard one depending on your means and preferences. However, I advise you to consider quality when making your purchase decision, as it can make a big difference.
With a budget of $4000 or above, you are in a better position to have a 3KW Solar Panel System installed at home by an expert.
It is also wise to note that prices may also be influenced by the type of brand.
Installation and Maintenance
The phases of installing a 3KW solar energy system begin with site evaluation, system design, permit acquisition, system installation, and grid connection.
There are a few materials required for the installation of 3KW Solar Panel like:
- Aluminum extruded rails from K2 systems for mounting all the panels
- Micro-inverters used to connect one to another
- an extension cable to run directly from the plug on the micro inverter
During installation, the solar inverter size should be considered to avoid under sizing or over sizing. The right way of installing the system by professionals ensures its safety and proper performance.
An average budget of $4200 is likely to facilitate installing a 3KW Solar Panel System for residents within Australia. However, you may need to check for price changes as time goes by.
The cost can also be affected by installation factors such as roof type and house type (for instance double-story…etc.), due to extra requirements such as mounting systems and additional equipment.
In case of minimal space on the roof, you may consider mounting your 3KW solar panel on the ground. Periodical services, such as washing the panels and checking for shades or damage, help preserve efficiency and prolong the system’s life.
This can be done at least once or twice a year for smooth operation of the 3KW solar system. Proper maintenance will ensure that you get the best value out of the solar system, and as owner of the system, you may get up to 20 years of usage.
This will give you a high return on the $5000 (for example), invested in purchase and installation.
Conclusion
A 3KW Solar Panel System would be a great practical and economical way to utilize solar energy in Australia. This review of the provisions of the “3KW solar panel dimensions” and its performance can help homeowners make informed decisions on energy usage and budgeting issues.
With the latest advances in solar technology, the benefits of going solar are getting more and more irrefutable, making it a far-sighted choice for a greener today.
