Household Solar Energy Adoption Continues To Climb
Recent figures from Roy Morgan confirm that Australian households are rapidly scaling up their use of solar energy systems. Around 32% of households now operate some form of solar solution, including hot water systems, heated pools, or rooftop PV. Within this segment, approximately 27% have rooftop solar panels and about 5% already combine panels with a storage battery system, representing more than 3.3 million homes with access to on-site generation. Full details are available in the official Roy Morgan analysis.
The data highlights strong regional penetration. Western Australia and South Australia lead on rooftop solar panel ownership at around 37% of households each, followed by Queensland at about 33%. In South Australia and the Northern Territory, adoption of solar battery systems is already above the national average, supported by targeted state programs focused on residential storage.
Household Uptake of Solar Energy Systems and Rooftop Panels by Australian State and Territory, September 2025
| Region | Households with Solar Energy (incl. hot water, heated pool) | Households with Roof Solar Panels | Households with Roof Solar Panels and Storage Battery |
|---|---|---|---|
| TOTAL | 32% | 27% | 5% |
| N.S.W. incl. ACT | 26% | 23% | 5% |
| Victoria | 28% | 23% | 4% |
| Queensland | 37% | 33% | 4% |
| South Australia | 41% | 37% | 9% |
| Western Australia | 41% | 37% | 4% |
| Tasmania | 23% | 21% | 5% |
| NT (Darwin – Alice Springs) | 39% | 29% | 7% |
Policy Support Accelerates Solar Battery Uptake
Policy design is a key driver behind these numbers. Multiple state schemes, combined with federal rebates, have made solar energy systems significantly more affordable. Subsidies have proven more effective than interest-free loans in encouraging households to invest in a solar battery or hybrid storage battery system, particularly in South Australia and the Northern Territory.
Looking ahead, the federal Cheaper Home Batteries Program, launched by the Department of Climate Change, Energy, Environment and Water together with the Clean Energy Regulator, provides around a 30% discount on eligible small-scale battery systems between 5 kWh and 100 kWh. Roy Morgan’s time-series data shows that residential storage batteries have already grown by about 82% since 2020, and this support is expected to drive further deployment through to 2030 as battery prices gradually decline.
Implications For Global Storage Battery Supply Chains
For international distributors, trading companies, and project developers serving Europe, North America, South America, and other markets, the Australian trend is an important reference point. Once rooftop PV reaches a certain level of penetration, households and small businesses increasingly look to solar battery and storage battery technologies to capture more of their own generation, reduce exposure to volatile tariffs, and stabilise long-term energy costs.
That shift creates sustained demand for high-cycle, safe lithium-based systems across residential, small commercial, telecom backup, and decentralised infrastructure. It also reinforces the need for scalable manufacturing partners that can support multi-country portfolios rather than single projects.
How MANLY Battery Supports Growing Demand For Solar Energy Storage
Against this backdrop, MANLY Battery works with B2B customers who import and distribute lithium and LiFePO4 products at scale for solar energy and storage applications. From manufacturing bases in Shenzhen, Dongguan, and Huizhou, MANLY supplies 6 V to 72 V LiFePO4 and lithium-ion packs that can be configured for rooftop PV storage, hybrid inverters, small commercial cabinets, telecom systems, and other battery-based infrastructure.
For wholesalers and OEM integrators responding to the kind of growth documented in the Roy Morgan solar energy report, MANLY’s portfolio offers long-cycle LiFePO4 modules with integrated BMS protection and international certifications such as UN38.3, IEC62133, UL, and CE. This combination allows partners to build standardised storage battery and solar battery solutions for multiple markets while meeting local safety and performance requirements, supporting the next decade of global distributed solar deployment.
