📖 How to Understand Your Results

Self-Consumption is Key: Solar saves you the most money when you use the power as it is generated. When your solar panels produce more energy than you are currently using, the surplus is often exported to the grid at a lower rate, or stored in a battery.

Payback Period: This is the time it takes for your cumulative energy savings to equal the initial installation cost. In Australia, a payback of 4–7 years is generally considered excellent.
Why "Net" Cost? Always input the final cost of your system after any government rebates (like STCs) have been deducted.
Maintenance: Remember that while solar is low-maintenance, panels may require professional cleaning every 2-3 years to maintain peak efficiency.
