However, actual output varies according to your geographic location and climate, orientation and pitch of your solar panels, as well as roof shading. But don’t worry – our technicians know how to position your panels for maximum efficiency, ensuring you generate the most power possible.

Output also depends on the quality of your panels and inverter. Higher quality systems perform better under high temperatures and deliver reliable results over the long term, which is why it’s worth investing in the highest quality system you can afford.

How much you get back from your 7kW solar system depends on how much solar energy you consume, and how much you export back to the grid.

A good quality 7kW solar system will have paid for itself within 2.5 to 4 years. The power it generates is far more valuable when consumed than exported back to the grid. So if you use as much of the power your system generates as possible, you’ll see a return on your investment in no time.
