Solar Panel Installation Cost Sydney 2026 — System Prices, STC Rebates, Feed-In Tariffs and What Sydney Homeowners Pay

Solar Panel Installation Cost in Sydney 2026

Sydney is one of the best cities in the world for residential solar — high sunshine hours, competitive installer market, strong STC rebates, and rising electricity prices that improve solar payback periods year on year. A well-sized system typically pays back in 4-6 years for Sydney homeowners, then generates free electricity for 20+ years. This guide covers solar panel installation costs in Sydney in 2026.

Sydney Solar System Prices (Installed)

• 3kW system: $3,500-$5,500 installed after STC rebate
• 6.6kW system (most popular residential size): $5,500-$9,000 installed after STC rebate
• 10kW system: $8,000-$13,000 installed after STC rebate
• 13.3kW system (maximum for single-phase): $10,000-$16,000 installed after STC rebate

STC Rebates for Sydney Solar

• Sydney is in STC Zone 3 (moderate solar irradiance zone for STC calculation purposes)
• STC rebate on a 6.6kW system in Sydney: Approximately $2,500-$3,500 at 2026 STC prices (fluctuates with STC spot price); this rebate is typically deducted at point of sale by your installer, who claims the STCs on your behalf
• STC deeming period reduces by one year on 1 January each year; installing in 2026 rather than 2027 captures one more year of deeming and a slightly higher rebate

NSW Solar Feed-In Tariff

• NSW has no mandated minimum solar feed-in tariff (FiT); rates are set competitively by retailers and typically range from 5-12 cents/kWh in 2026; compare retailer offers before signing up
• Self-consumption (using solar electricity yourself rather than exporting) is worth 25-35 cents/kWh in avoided bills — far more valuable than the export FiT; maximise self-consumption with smart appliance scheduling

NSW Empowering Homes Program

• Interest-free loans for eligible NSW households to install solar (and/or battery); check eligibility and current program funding status at the NSW Government Energy website before getting quotes
