How we calculate the savings?

​

​

We’ve recommended a system size and estimated savings based on your electricity bill and other information you input here. We have assumed you will purchase your system upfront.

​

Estimated savings include an estimate of how grid electricity could be replaced by solar electricity, and how much surplus energy you export back to the grid. Calculations use the Standing Contract ‘Peak Only’ tariff for your Network distribution zone and may vary if you are on a ‘Time of Use’ tariff.

​

Your actual savings may vary according to a range of factors including your location, which direction your roof faces, the pitch or angle of your roof, shading or obstruction and weather/climate conditions.

​

Potential savings on the electricity bill and payback estimations do not take into account any maintenance or inverter replacement costs that you may incur during the product’s lifetime.

​

The savings are based on our Advantage Range and assume roof orientation of north and a roof pitch (angle) of 30 degrees.
