Australia’s rooftop solar sector has achieved a new milestone, with the Clean Energy Regulator (CER) reporting a record 791 megawatts (MW) of small-scale solar capacity installed across the nation in the first quarter of 2026. This significant surge, detailed in the CER’s Quarterly Carbon Market Report for March quarter 2026, published on June 3, 2026, underscores the continued commitment of Australian households and businesses to renewable energy and offers critical insights into current market dynamics for those considering solar.
The 791 MW figure for Q1 2026 represents an unprecedented level of small-scale solar deployment for a single quarter, reflecting robust consumer demand despite ongoing adjustments to federal Small-scale Technology Certificate (STC) rebates. This record uptake highlights solar’s established role in reducing electricity bills and enhancing energy independence for Australian properties.
The Cost of Going Solar in 2026
While Australians are installing more solar than ever, understanding the current investment required is crucial. As of June 2026, the average cost for a typical 6.6 kW residential solar system in Australia, after accounting for federal STC rebates, generally falls between AUD$5,500 and AUD$7,500.
For larger installations, such as a 10 kW system, homeowners can expect to pay approximately AUD$8,000 to AUD$13,000 post-rebate. The national average price per watt for residential solar panels, fully installed and including GST and the STC rebate, ranges from AUD$0.88 to AUD$0.95.
“Small-scale solar hit record levels, with 791 MW installed in Q1 2026,” the Clean Energy Regulator’s March quarter 2026 report stated, underscoring the rapid expansion of rooftop PV across Australia.
These figures demonstrate that while the total investment for a larger system may be higher, the cost-effectiveness per watt remains attractive. Factors influencing the final price include the quality of panels and inverters, installation complexity, and regional variations. Queensland, for instance, often sees some of the most competitive pricing for solar installations.
Average Solar System Costs in Australia (June 2026, after STC rebate)
| System Size | Typical Cost Range (AUD) | Notes |
|---|---|---|
| 6.6 kW | AUD$5,500 – AUD$7,500 | Most common residential size. |
| 10 kW | AUD$8,000 – AUD$13,000 | Suited for larger homes or EV owners. |
It is important for prospective buyers to compare multiple quotes from accredited installers to ensure competitive pricing and quality components.

Impact on the National Energy Market and Your Savings
The record installation of small-scale solar in Q1 2026 is having a tangible impact on Australia’s energy landscape. The Australian Energy Market Operator (AEMO) reported in its Q1 2026 Quarterly Energy Dynamics that renewables supplied a record 46.5% of generation in the National Electricity Market (NEM) during the same period.
Rooftop solar plays a crucial role in this, with its output often offsetting underlying electricity demand. This increased renewable penetration generally contributes to downward pressure on wholesale electricity prices, although these savings are not always directly passed on to consumers via retail bills.
For individual households, a well-sized solar system can dramatically reduce quarterly electricity bills. By generating your own power, you lessen reliance on grid electricity, especially during peak demand periods when prices are highest. Maximising self-consumption of your solar energy is key to unlocking the greatest savings. Integrating smart home energy systems can further optimise your solar usage, potentially slashing your bills by up to 30%.

The Growing Role of Batteries
The CER report also highlighted the rapid growth in battery uptake, with over 11.4 gigawatt-hours (GWh) of usable battery capacity installed across Australia by mid-May. This trend is intrinsically linked to solar, as batteries allow homeowners to store excess solar generation for use during the evening or on cloudy days, further reducing grid imports and maximising the value of their solar investment.
The federal Cheaper Home Batteries Program and various state-level incentives continue to drive this uptake, making battery storage increasingly accessible.

Outlook for Australian Solar
The record Q1 2026 installations signal a robust and growing rooftop solar market in Australia. Despite the annual step-down of federal STC rebates, the underlying economic benefits of solar, coupled with increasing electricity prices and a desire for energy independence, continue to drive adoption. The ongoing integration of solar with battery storage is transforming how Australians consume and manage their energy, paving the way for a more resilient and sustainable energy future.
As the grid continues its transition, informed decisions about solar installation, system sizing, and energy management will be paramount for homeowners looking to maximise their savings and contribute to Australia’s clean energy goals.
