SolarQuotes Australian Solar Price Index

How much does solar power cost in Australia currently - and what about historically? 

This graph, updated in real-time, shows the average price paid over time in Australian dollars for a rooftop solar power system installation across the whole of Australia - from a few years ago to just last month. The prices noted are after STCs (aka the solar rebate) and any state-specific rebates. 

Note: Although the average price paid for all system sizes appears to be all over the place, this is not because the cost of solar is increasing and then suddenly decreasing. Australians are buying bigger systems; more than offsetting the decreasing cost per watt - which is indicated in the bottom graph.

The cost data, based on purchase date, is sourced from reviews submitted to SolarQuotes. We give every reviewer the opportunity to report the price they paid for their solar power system.
