The Illawarra region gets solid solar output year-round, with the escarpment providing some protection from westerly weather. Wollongong's relatively affordable housing stock means many homeowners have the budget headroom to invest in solar, and the area's high electricity consumption from older, less efficient homes creates strong savings potential.
💡 Local Tip
Homes backing onto the escarpment can experience afternoon shading earlier than expected. If your home faces west toward the escarpment, get a shading analysis done before choosing panel placement.
