How to maximise savingsusing solar power

The best way to make savings from solar power is to use as much electricity during the day when your panels are generating energy; we refer to this as self-consumption.

Unless you have a solar battery, any excess power that you don't use gets exported back to the grid. You will receive a feed-in tariff for each kilowatt-hour you export, but it is only roughly 40% of what you pay for electricity. Factor this in mind when using the calculator, the higher the percentage of electricity you use during the day, the higher your solar savings will be.

Variables in calculatingsolar power output

The output of your solar power system will vary depending on several factors. These factors include weather and climate, roof pitch (angle of your roof), roof orientation, shading or obstruction, the system size you select and the quality of the installation. Each of these elements will affect your system's performance and your potential solar savings.

solar output variables
Location: Sunshine hours
Orientation: Roof direction
Roof pitch: Angle of your roof
Shading: Is sunlight blocked?
System size: More panels = more power

Financial variables

There are also financial variables that affect your solar savings. These include the Australian government solar rebate, any state rebates, your feed-in tariff, the cost of your solar panels and the rate that you pay for your electricity.

we've got your covered

Our calculator factors in all of these variables before displaying your solar results. You can find further information on each facet of generating solar power throughout our site.
