Solar in Bankstown — What You Need to Know
Bankstown is Canterbury-Bankstown Council's commercial heart, and its residential streets tell the story of post-war Sydney suburban expansion: 1950s–70s brick veneer homes on 600–700m² lots that are well-suited to 10kW+ systems. The suburb's western Sydney location earns an extra 0.15 peak sun hours per day compared to coastal Sydney — seemingly small, but compounding to $110 more generation value annually over a 25-year system life. High electricity consumption — large families, multiple air conditioning systems, and strong work-from-home patterns — means Bankstown households self-consume 72% of their solar generation, well above the Sydney average. Canterbury-Bankstown Council has prioritised solar education in CALD communities, running Arabic, Vietnamese and Cantonese language solar information sessions that have measurably increased adoption in previously under-served streets.
