About Solar Panel ROI

Solar panels can significantly reduce your electricity bills and carbon footprint. This calculator provides an estimate of the potential financial returns from installing a solar system on your property, taking into account factors like system size, installation cost, electricity usage, and your location in Australia.

Results are based on average solar production data for Australian regions, current electricity rates, and typical solar system performance. The actual returns may vary based on specific installation conditions, future electricity price changes, and your personal energy consumption patterns.

Solar panel systems typically have a warranty of 25 years, though they can continue producing electricity for longer. For conservative estimates, this calculator uses a 25-year lifespan for calculations.
