Western Australia is one of Australia’s sunniest states, with high solar potential thanks to abundant sunshine and large rooftop spaces. That’s why homeowners and businesses across Perth and the surrounding regions are increasingly investing in solar power — reducing energy bills, enhancing sustainability, and increasing home value.
Here are the top five WA suburbs/postcodes leading the solar adoption boom:
📍 1. Wanneroo (Postcode 6065)
Installed Solar Capacity: ~91,839 kW This northern Perth region — including suburbs like Wanneroo and Ashby — tops the list for total solar capacity in WA. Large homes and generous roof space make it ideal for high‑capacity solar systems that not only power homes but often export excess electricity back to the grid.
Why it’s popular: Big roofs + community solar uptake + excellent sun exposure.
📍 2. Armadale (Postcode 6112)
Installed Solar Capacity: ~83,507 kW A close second, Armadale and its neighbouring suburbs have seen strong solar installation growth as residents prioritise energy independence and savings. Its sunny climate helps solar panels operate efficiently throughout the year.
Notable: Many homes choose systems sized to match local energy needs while maximising feed‑in tariff benefits.
📍 3. Cockburn (Postcode 6164)
Installed Solar Capacity: ~75,835 kW Located south of Perth’s CBD, Cockburn has seen significant solar adoption among both families and businesses. Many households in this area pair solar panels with batteries to store excess generation for evening use, boosting self‑consumption and reducing grid dependency.
Trend: Solar + battery hybrid systems for peak‑time power.
📍 4. Canning Vale (Postcode 6155)
Installed Solar Capacity: ~64,627 kW A well‑established suburb with a mix of residential and commercial solar systems, Canning Vale is a strong solar performer thanks to environmentally conscious residents and sizeable rooftops that easily accommodate solar arrays.
Commercial edge: Larger businesses in the area use high‑capacity systems to offset significant daytime energy demands.
📍 5. Ellenbrook (Postcode 6069)
Installed Solar Capacity: ~62,021 kW Ellenbrook rounds out the top five, driven by modern housing developments with solar‑ready design and smart inverter technologies. Families here are increasingly adopting solar as both a financial and environmental investment.
Modern appeal: New homes often integrate solar from the start.
