Solar in Randwick — What You Need to Know
Randwick sits on a ridge running east from Randwick Racecourse to the coastal cliffs at Coogee and Clovelly. The suburb's 1920s–1940s brick homes on the ridge lines have outstanding north-facing roof planes, but the valley pockets near The Spot and Randwick Junction are heavily shaded by mature street trees. The local demographic skews young and educated — UNSW staff and medical professionals from Prince of Wales Hospital — creating unusually high awareness of solar economics without the family-home tenure that typically drives installation. Randwick Council has a strong sustainability agenda and has approved solar on 97% of heritage applications since 2022, including in the conservation zones around Alison Road. The eastern suburb's coastal proximity means marine-grade components are worth the extra $400 on any system within 500m of the shoreline.
