Pricing & eligibility
Pricing is indicative only; final system design and price vary with your property and load requirements. Government subsidy estimates are based on STC zone 3 for installations on or before 31/12/26, vary with market price and location, and decrease each calendar year — eligibility is assessed by OffGrid WA. Pricing applies within 100km of Wangara, Perth; rural sites may attract additional travel, logistics and accommodation costs. Groundworks, trenching, concreting and bespoke electrical works are not included. All off-grid systems require a support generator for redundancy during prolonged poor weather; OffGrid WA recommend a 10 kVA diesel generator (240V single-phase).
