    TEN KILOWATT SOLAR ROOFTOP SYSTEMS

    10kW solar systems are a great investment for Australian homes with high levels of electricity consumption or businesses with relatively small electricity needs. Most residential solar panels have a output rating of 330W to 400W meaning a 10kW system will need 25 to 30 solar panels and will require about 80 square metres of roof space. More efficient solar panels will reduce the roof space required and typically cost more as they are utilising newer technologies.

    Solar Choice publishes a monthly Solar PV Price Index that tracks average pricing trends in every capital city in Australia. According to Solar Choice’s data, the average 10kW solar system price in Australia as of November 2021 is about $0.91 per watt – or about $9,090 after the federal STC rebate is deducted.
