For Australian houses with high electricity usage or businesses with relatively low electricity needs, 10kW solar systems are an excellent investment.
GoRunSolar will install the most suitable 10 kW solar system for your requirements. We provide high-quality solar panels from Jinko, Canadian, Trina, and Longi, as well as high-quality solar inverters from Sungrow and Fronius inverters.
According to GoRunSolar's own data, the average 10kW solar system price in Australia as of the end of 2021 is around $0.91 per watt – or around $9,090 after the federal STC rebate. Price of the solar installation in Brisbane may also vary depending on brands and solar panel costs.
Most household solar panels have a 330W to 400W output rating, so a 10 kW system will require 25-30 solar panels and 80 m2 of roof area.
A higher-quality solar panel will be more efficient, requiring less roof space, and will often cost more depending on the brand.
The actual power output of a 10 kW solar power system in Brisbane will vary depending on a number of factors. The energy output is affected by factors such as the solar panel array's orientation and tilt angle, the operating temperature of the panels, and even if the panels are shaded.
Taking into account all of the aforementioned, a north-facing 10 kW solar system in Brisbane will generate between 40 and 45 kWh per day.
For home, 10 kW solar systems installation is on the larger side (where 5 kW to 6.6 kW is much more common). As previously stated, 10 kW systems are best suited for residences that consume a substantial quantity of electricity during the day (or businesses with about 40 kWh of daytime usage).
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.
Solar feed-in tariff credits are now a supplementary benefit of installing a residential solar system. Instead, you will get the best value from your self-generated solar energy by 'self-consuming' it, or directly using as much of it as possible.
Because solar feed-in tariff rates are typically lower than what you will pay for energy from the grid, the more solar energy you use yourself, the more money you will save; in the meantime, the excess solar will flow into the system and earn you credits, which will help lower your overall bill.
The difference between retail electricity (16 cents/kWh) and solar feed-in (5 cents/kWh) pricing in Brisbane is almost 10 cents.
According to our experts from best solar installers in Brisbane, for property owners with lower self-consumption rates, such as 30%, the payback time for a 10 kW solar power installation in Brisbane close to 6.9 years.
While higher self-consumption rates, such as 60%, could result in a payback time of as little as 4.7 years. The rewards will appear much better if you can increase your self-consumption rates even more.
