Adelaide combines a sunny dry climate with the cheapest mainland install labour, a strong solar-savings pairing.
The rest is exported for the feed-in tariff.

How we estimate this
Solar savings depend on your state’s sunshine, how much of the generation you use at home (versus export), your electricity rate and feed-in tariff, and the system cost. Using more solar during the day dramatically improves the return.

What a solar savings costs in Adelaide
Adelaide's dry Mediterranean climate delivers plenty of clear, sunny days, so a well-oriented system generates reliably and the economics stack up, while the most affordable trade labour of the mainland capitals keeps the install cost down. The housing stock of accessible single-storey post-war brick and stone cottages generally offers simple roof lines, so mounting is straightforward and the labour share of the quote stays low.
Household load leans on summer cooling in the warm, dry climate, which aligns neatly with peak solar output, so daytime users capture the strongest benefit. South Australia's high retail power prices sharpen the case further, since every self-consumed kilowatt-hour offsets an expensive one from the grid. Older stone cottages with small or complex roofs can limit array size, but for a conventional Adelaide home the sun and the low install cost make solar an easy sum.

Frequently asked questions
How much does solar save in Australia?
A typical 6.6kW system saves around $1,000–$1,800 a year depending on your state, power use and tariffs. The calculator estimates your specific saving and payback.
How long until solar pays for itself?
Most systems pay back in 3–6 years. Using more of your solar during the day (rather than exporting it) shortens the payback period.
Does my state affect solar savings?
Yes, sunnier states like QLD, WA and NT generate more per kW than VIC or TAS. The calculator adjusts generation for your state’s average sun hours.
