A 13.2kW solar system installed in Australia will generate approximately 52kWh per day on average. Before installing a 13.2kW solar power system, our expert professionals will check the size of your roof to ensure commercial solar sumner that you get the most out of your solar system.

The cost of installation can vary depending on the complexity of the installation, such as the type of roof, mounting system, and wiring required. Some rooftops cause installers more difficulty when installing solar panels and more complications with wiring and this can increase the cost of a solar system. The larger the solar system, the more solar panels and other equipment is required, which can increase the cost. However, the larger the solar system is, the more electricity it produces which, in turn, allows households to save more on energy costs.

Inverters are critical in converting the solar energy stored in batteries into usable electricity. Some inverters are more efficient and compatible with specific battery types, affecting overall costs. Hybrid inverters that combine solar and battery systems can drive up the price but offer greater efficiency in energy use. You are eligible for a solar panel rebate from the Australian government and save more on solar.
An additional consideration is that many of the electricity retailer’s feed-in tariff plans are capped at systems with a 10kW inverter. Heidi-Lee Douglas from advocacy group Solar Citizens said buildings with larger roof spaces could be used to help power bigger, denser apartment blocks.

If you need more power, your solar panel system will automatically buy electricity from the grid. If you have excess solar power, your solar will automatically sell it back to the grid. We recommend that you consume at least 30% of the solar energy generated by your system. Also, your network provider’s default limit on solar system size may differ; you may be required to complete additional documentation and inspections to install a 10 kW solar system in Brisbane. A higher-quality solar panel will be more efficient, requiring less roof space, and will often cost more depending on the brand. Most household solar panels have a 330W to 400W output rating, so a 10 kW system will require solar panels and 80 m2 of roof area.
The federal solar rebate – STC program – winds back each year until it is phased out completely in 2030. This provides upward pressure on solar pricing but has been overshadowed in the early solar years with the cost of solar decreasing. A double-storey house can increase the cost of your solar power system as can any access issues to your property. Two key variances that impact the cost of a solar system are the size of the system and the rebate. Once you have decided on a system size and how many panels you need, several variables will impact the price of that system.
