Commercial solar in Perth costs roughly $650–$900 per kW installedat 30–100kW scale (2026, after the STC discount) and typically pays back in 3–4 years for daytime-heavy operations. Systems under 100kW still qualify for the federal STC discount — about $8,177 on a 30kW installation.
3–4 year typical payback
Daytime-heavy operations see the fastest returns in WA — every kWh you self-consume avoids a peak commercial rate rather than earning a feed-in tariff.
Engineering included
Structural assessment, Western Power approvals, network protection studies and compliance documentation, handled end to end.
Incentives itemised
