When you use your
power is important

The variable that effects the economics of your solar system most is; the amount (%) of electricity that you use during the day when your solar panels are producing energy. In short, the more you use during the day the better.

Unless you have the ability to store the energy your panels produce via a solar battery, any excess energy you don’t use will be exported back into the grid.

With feed in tariff rates so low in many states, there is little incentive to export your excess solar power. Your best saving will come from using your own generated power during the day. Factor this in mind when using the calculator. The higher the percentage of electricity you use during the day, the better your solar savings will be.

Variables in calculating solar power output

The performance of a solar power system varies depending on several factors, for example: weather and climate, roof pitch (angle of the roof), roof orientation, shading or obstruction and the number of solar panels and the quality and efficiency of those panels. Each of these elements will affect the solar performance and the potential solar savings of your system.

Financial variables

Some additional, financial variables include: applicable government rebates, state government feed in tariffs, any abnormal installation cost as a result of your property type, and the price you pay for electricity through your current retailer.

We've got
you covered

Our calculator factors in all of these variables before displaying your potential solar results, whilst further information on each of these areas can be found throughout our site. If you're an existing solar panel owner, we provide a solar storage calculator to weigh up the feasibility of solar batteries.
