Solar in Prahran — What You Need to Know
Prahran's Victorian terrace houses and Edwardian homes are beautiful but challenging for solar. Stonnington Council's heritage overlays apply broadly, and the east-west orientation of most terrace lots limits north-facing roof area. However, the large double-fronted homes on Chapel Street's residential streets are excellent solar candidates — wide roof spans can host 12–16 panels facing north-south. Solar Homes Program rebates (VIC) apply here, adding $1,400 for eligible households. Prahran's progressive demographic has strong environmental awareness but many households are renters who can't access rooftop solar.
