Commercial solar for Perth businesses
Commercial solar in Perth costs roughly $650–$900 per kW installed at 30–100kW scale (2026, after STC rebate) and typically pays back in 3–4 years for daytime-heavy operations. Systems under 100kW still qualify for the federal STC rebate — about $8,000–$10,000 on a 30kW installation.
3–4 year typical payback
Daytime-heavy operations see the fastest returns in WA — every kWh self-consumed avoids peak commercial rates.
