Our take on solar in SA
South Australia has the highest solar irradiance of any mainland state capital, with Adelaide averaging 5.0 peak sun hours per day. A 6.6kW system generates 27 to 33 kWh per day. Combined with the highest electricity prices in Australia, solar payback in SA is the fastest in the country: typically 3 to 5 years. The Solar Sharer Offer (from July 2026) provides free electricity from 12pm to 3pm for smart meter households. SA is the state where solar plus battery makes the strongest financial case.

Self-consumption first. Every kWh you use from your panels avoids buying at 25 to 40 cents from the grid. Exporting earns only 3 to 10 cents. Shift your dishwasher, washing machine, pool pump, and EV charging to daylight hours.
Compare the total estimated annual cost, not just the feed-in rate. A plan with a high feed-in rate but high usage rate can cost more overall than a plan with a moderate feed-in rate and low usage rate.
Battery rebates in SA. The old SA Government Home Battery Scheme (which offered up to $2,000) has closed. There is currently no additional state battery incentive in South Australia beyond the federal Cheaper Home Batteries Program, which discounts roughly 30% off the upfront cost of a battery (tapering above 14 kWh).
