What's the federal STC rebate worth in 2026?
The Small-scale Technology Certificate (STC) scheme automatically discounts your solar system at point of sale. Value depends on system size and location zone (Australia divided into 4 zones based on solar resource). For a 6.6kW system: Zone 1 (Darwin, FNQ): ~$3,500. Zone 2 (Brisbane, Perth): ~$3,200. Zone 3 (Sydney, Adelaide): ~$2,800. Zone 4 (Melbourne, Hobart): ~$2,400. The rebate is built into the price installers quote — you never claim it separately. STC values change with carbon market prices and reduce each year (10% reduction in 2030).
