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).

Battery economics improved significantly in 2026 with the Federal Cheaper Home Batteries program ($4,000-$7,000 rebate per battery from 1 July 2025). Best for: high evening electricity use, flat or low feed-in tariffs ($0.04-$0.08/kWh in most states), planning long home occupancy (10+ years), EV ownership, virtual power plant participation (extra income). Payback time with rebate: 6-9 years on a $13,000 battery. Top brands 2026: Tesla Powerwall 3, BYD Battery Box, AlphaESS, Sungrow, Sigenergy.

Feed-in tariff is the rate your electricity retailer pays for excess solar energy you export to the grid. Rates have declined dramatically: 2010 $0.40-$0.60/kWh, 2020 $0.10-$0.15/kWh, 2026 typically $0.04-$0.08/kWh (some retailers offer higher with conditions). Rates vary by state and retailer — compare on Energy Made Easy (energymadeeasy.gov.au). Strategy: maximise self-consumption (use power when generating) rather than relying on export. Battery storage shifts excess to evening use instead of low-rate export.
