What SA households get paid for surplus solar exported back to the grid in 2026. Market structure, typical rates, time-of-use bands, and the grandfathered schemes still in effect.

How SA's feed-in tariff market works

South Australia is fully deregulated. Retailers set their own feed-in tariffs and may include conditions (export limits, time-of-use bands, dynamic exports based on local network conditions).

Time-of-use feed-in tariffs

SA Power Networks operates dynamic export limits — the maximum kW your system can export can vary by time of day based on local network capacity. Some retailers price FiT to reflect this.

What's actually worth chasing

SA has the highest residential solar penetration in Australia, which depresses wholesale midday prices and FiTs. Self-consumption + battery storage typically pays back faster than chasing higher FiTs.

Considering a battery for SA?

Battery economics depend heavily on your FiT — the lower your export rate, the more valuable a battery becomes. The federal Cheaper Home Batteries Program rebate steps down 19% on 1 May 2026.
