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.

Engineering included

Structural assessment, Western Power approvals, network protection studies and compliance documentation handled end to end.

Incentives itemised

STC rebate (~$8–10k on 30kW), accelerated depreciation and commercial finance options laid out line by line in your proposal.

BNEF tier-1 equipment only

Commercial-grade panels and inverters from manufacturers with verified bankability and Australian support offices.
