Solar in Eight Mile Plains — What You Need to Know
Eight Mile Plains is home to Brisbane Technology Park, one of Australia's largest technology employment precincts, and its residential streets house the engineers, software developers, and IT professionals who work there. The suburb's solar market reflects this demographic almost perfectly: high average system sizes (10.8kW), highest battery attachment rate in Brisbane (48%), real-time monitoring standard on 82% of installations, and a market that actively compares installer proposals using spreadsheet modelling. Housing stock is predominantly 1990s–2010s brick on 600–700m² lots with good north-facing orientation, and Brisbane City Council's planning framework is straightforward.
