Solar Power In Australia – Information & Statistics

Last Updated: 20th Oct 2026

Australia’s home solar power revolution has been nothing short of phenomenal. When I started this site back in 2009, there were just 85,000 solar systems connected to the mains grid in Australia by the end of that year – and Australia’s first solar farm was yet to be built.

Fast forward to the end of August 2026 and more than 4.53 million solar panel systems have been installed on rooftops throughout the nation. Gigawatts of large scale solar energy projects are also operational, under construction or in the pipeline.

In fact, more solar panels have been installed on rooftops of homes in this country than there are people in Australia. Here’s how Australia’s small scale solar energy (systems less than 100kW capacity) revolution has progressed over the years. As you can see,  it shows no signs of really slowing down at this stage.

Note: due to the way the Clean Energy Regulator collects its statistics, the figure above for 2025 will continue to increase during 2026. The Regulator also reviews its statistics from time to time for earlier years, so figures may vary (but usually not by much).

Collectively, the 4,264,061 systems noted represent more than 27.8 gigawatts of electricity generation capacity! At the time of writing, around 1.81 kilowatts (kW) of small scale PV had been installed per Australian.

So, Is Solar Worth It In Australia In 2026?

Home solar installations will continue at a rapid clip in Australia in 2026 for a simple reason – it’s certainly still worth it to get panels installed on your rooftop in order to slash your electricity bills.

The generous solar rebate is still available (as are other solar and battery rebates and subsidies depending on your location), feed in tariff incentives still apply although rather miserly these days and the cost of solar panels is well within reach of many households. Simple payback on a system is generally very rapid in a situation where a home has a compatible rooftop and a good quality installation is performed.
