South Australia is a national leader in rooftop solar, with over 40% of homes already powered by the sun. Our state enjoys some of the best solar insolation in Australia, with Adelaide averaging 5.2 peak sun hours per day.

South Australia boasts the highest penetration of rooftop solar in the country, with over 1 in 3 homes already installed, according to the Clean Energy Regulator. The state's sunny climate delivers exceptional solar output: Adelaide receives around 2,400 hours of sunshine annually, with daily peak sun hours ranging from 4.9 in winter to 5.8 in summer. This translates to a 6.6kW system generating approximately 27 kWh per day, enough to cover the average household's consumption of 20 kWh/day. The state also faces higher than average electricity prices, making solar an even more attractive investment. With net metering and feed-in tariffs typically between 5¢ and 12¢ per kWh, you can offset your usage and earn credits. Plus, SA's grid is increasingly powered by renewables, so you're contributing to a cleaner future. However, because SA has a high penetration of solar, grid stability and transformer upgrades are considerations — your installer will ensure your system complies with local DNSP (SA Power Networks) requirements.
Going solar in SA is more affordable thanks to a combination of federal and state incentives. The Small-scale Technology Certificates (STCs) scheme remains the backbone of upfront discounts, reducing the cost of a typical 6.6kW system by $3,000–$4,000. From 1 July 2025, the new Cheaper Home Batteries Program provides additional support for battery storage, building on the state's own SA Home Battery Scheme (SAHBS). The SAHBS offers low-interest loans of up to $5,000 for battery systems, and a $500 subsidy for eligible households. Additionally, the federal government's Solar for Households initiative (coming in 2025) may further reduce costs. The Clean Energy Regulator reports that over 6.5 million small-scale solar systems have been installed nationally, with SA contributing over 400,000 systems as of 2024. Always check your eligibility with a CEC-accredited installer, as rebates are subject to postcode and property type. MrSolar's installers will guide you through every rebate and ensure you maximise your savings without any hidden costs.
Selecting the right solar installer is critical for system performance, safety, and warranty. In South Australia, all installers must be accredited by the Clean Energy Council (CEC) to design and install grid-connected solar systems. MrSolar only works with CEC-accredited installers who have been vetted and reviewed by real customers. This ensures your system meets Australian standards (AS/NZS 5033 and AS/NZS 4777) and is eligible for government rebates. Our three-step process makes it easy: 1) Tell us about your home — share your roof type, electricity usage, and budget. 2) We match you with up to three CEC-accredited installers in your area — each providing a custom-designed system. 3) Compare quotes and choose — there's no obligation, and our installers are known for low-pressure, transparent advice. With over 6.5 million solar systems installed nationally, CEC accreditation is your guarantee of quality. Plus, SA Power Networks requires all new connections to meet strict standards, and your installer will handle all paperwork and approvals.
Solar is a smart investment for most SA households, but there are key factors to consider. Your roof matters: north-facing or east-west roofs with good sunlight exposure (no heavy shading) are ideal. If you have a large family or run air conditioning in summer, a larger system (e.g., 7.7kW) may be better. South Australia's net metering policy means you can offset daytime usage and export excess, but feed-in tariffs are relatively low, so you'll want to use as much solar as possible during the day. If you're home during the day, solar is a no-brainer. For retirees or WFH professionals, a system with a battery (via the SA Home Battery Scheme) can maximise self-consumption. Another sign solar is right for you: you pay over $1,200 per year in electricity bills. Even renters can benefit — some landlords install solar to increase property value. And with the federal Cheaper Home Batteries Program coming in 2025, now is a great time to consider energy storage.
