Solar in Byford — What You Need to Know
Byford sits on the scarp above the Darling Range southeast of Perth, a rapidly growing outer suburb that has become a benchmark for solar-inclusive residential development. Stockland's Byford on the Scarp development — one of WA's largest active residential estates — made solar standard in all new homes from 2022, following pressure from buyers who were comparing Byford to solar-inclusive estates in Queensland and SA. The resulting adoption rate among new stock (100%) has pulled up the suburb's overall penetration rapidly. The Shire of Serpentine Jarrahdale has accommodating planning policies for solar across all residential zones. Byford's inland position on the scarp gives it Perth's excellent sun resource (5.0 peak hours) without coastal marine concerns, and the cooler scarp elevation (200m) keeps panels at lower operating temperatures in summer — recovering 3–4% of output that heat stress removes in Perth's coastal suburbs.
