Solar in St Ives — What You Need to Know
St Ives is one of Sydney's greenest suburbs — and that works both for and against solar. The dense tree canopy of Ku-ring-gai's bushland setting creates localised shading on many north-facing rooftops, reducing output by 8–15% compared to open suburban sites. However, the large blocks and single-storey brick homes from the 1960s–80s have excellent roof area. Ku-ring-gai Council's heritage overlays apply to some streets but most standard residential solar requires no DA. The suburb's high-income demographic drives demand for premium tier-1 panels (REC, SunPower) and quality inverters — average system size here is 8.5kW, well above the Sydney average of 7.1kW.
