May 2026: The Australia solar power market continued achieving record rooftop installation levels. Australia registered a record 442 MW of new small-scale rooftop solar capacity in April 2026, representing a 31% month-on-month increase and almost double the volume installed in April 2025. The surge was largely driven by rapid adoption of home battery systems under the federal Cheaper Home Batteries Program.
May 2026: Australia’s residential battery boom is significantly strengthening solar adoption and grid flexibility. More than 350,000 home battery systems had reportedly been installed within the first 10 months of the Cheaper Home Batteries Program, helping households store excess rooftop solar generation and reduce evening grid demand.
May 2026: Renewable energy and solar generation are increasingly lowering wholesale electricity prices across Australia. According to Australian Energy Market Operator data, renewable energy sources including solar, wind, hydro, and batteries generated nearly 47% of electricity during the first quarter of 2026, while gas-fired power generation fell to its lowest quarterly average since 1999.
April 2026: Australia’s rooftop solar fleet exceeded approximately 28.3 GW of installed capacity across around 4.3 million installations nationwide by the end of 2025. Rooftop solar contributed approximately 14.2% of total electricity generation during the second half of 2025, highlighting Australia’s position as one of the world’s leading rooftop solar markets.
April 2026: Utility-scale solar projects continue facing profitability pressure due to falling wholesale electricity prices and increasing renewable generation. Genex Power scaled back the first stage of its Bulli Creek Clean Energy Park project in Queensland from an originally planned 775 MW solar farm to approximately 300 MW, while delaying construction timelines because of difficult market conditions.
March 2026: Australia’s rooftop solar market recorded the largest February installation total in history, with approximately 281 MW of new rooftop solar capacity installed during the month. Year-to-date installation volumes were approximately 6% ahead of the same period in 2025, demonstrating continued strong consumer demand despite broader market maturity.
February 2026: The Clean Energy Regulator projected that Australia could install between 350,000 and 520,000 residential battery systems in 2026, representing approximately 8–12 GWh of storage capacity. The regulator also forecast rooftop solar installations could rebound to between 3 GW and 3.7 GW during 2026.
February 2026: BloombergNEF reported that investment in Australia’s utility-scale solar sector declined by approximately 35% in the second half of 2025, with financing falling to around AUD 379 million. Most newly financed projects now include integrated battery energy storage systems as developers increasingly prioritize hybrid renewable energy projects.
January 2026: Australia added approximately 7 GW of renewable energy capacity during 2025, with renewables supplying nearly 43% of total electricity generation nationally. Government and industry stakeholders continue targeting 82% renewable electricity generation by 2030, supported by ongoing expansion in rooftop solar, batteries, and large-scale renewable infrastructure.
2025–2026 (market trend): The Australia solar power market is being shaped by record rooftop solar adoption, rapid battery storage deployment, falling renewable generation costs, and growing electrification of households and businesses. Solar-plus-storage systems are increasingly improving grid reliability and reducing dependence on fossil fuel generation. At the same time, transmission bottlenecks, declining wholesale power prices, project financing challenges, and grid integration complexity continue to influence utility-scale solar development across the country.
The Australia solar power market is becoming a major pillar of the country’s renewable energy transition and decarbonization strategy.
With projected growth from USD 9.6 Billion in 2025 to USD 33.9 Billion by 2034, the market demonstrates substantial expansion potential driven by renewable energy investments, declining technology costs, and increasing adoption of sustainable power solutions.
As Australia continues accelerating its clean energy transition, solar power is expected to play a critical role in supporting energy security, emissions reduction, and long-term environmental sustainability.

On Tuesday night, I was a little naughty. I indulged in culture, in a night supporting the arts. I should have been at a Parent Teacher Association meeting, discussing the raising of funds for the desperately needed school minibus but I eschewed this for a private invitation to a viewing of Darrell Warner's latest exhibition Crucifixion. Don't think too badly of me. In fact, let's move the focus from me and on to Darrell and his works.
