Solar in St Kilda — What You Need to Know
St Kilda is Melbourne's most famous suburb and one of its most challenging for solar. The dense concentration of heritage-listed Victorian terraces, art deco apartments, and Edwardian mansions creates real planning barriers. Port Phillip Council's heritage overlay (HO) covers most of the suburb, requiring panels to be invisible from the street and, in some cases, requiring a planning permit. For freestanding homes on side streets away from the foreshore, north-facing rear slopes work well. The suburb's high proportion of renters (62%) limits demand significantly — solar is a homeowner decision. Bayside location means salt air hardware considerations apply.
