Sydney gets excellent sun despite its reputation for coastal cloud. With some of Australia's highest electricity rates and strong STC Zone 2 rebates, solar payback periods in Sydney are among the shortest in the country. The mix of older tile roofs in the Inner West and newer builds in the growth corridors means system design matters — but almost every Sydney home can benefit from solar.
💡 Local Tip
Sydney's coastal suburbs can experience salt spray corrosion, so if you're near the beach, ask your installer about corrosion-resistant panel frames and mounting hardware.
