Solar in Tea Tree Gully — What You Need to Know

Tea Tree Gully is one of Adelaide's solar champions in the northeastern foothills. The suburb's 1970s–90s concrete tile homes on Adelaide Hills-adjacent blocks are solar-ready, and the slightly elevated position gives marginally better winter sun angles than the flat CBD plain. SA's high electricity prices make solar unavoidable economics here — households save $1,600–2,000/year on a standard 6.6kW system. Tea Tree Gully Council has been an active solar advocate. The area's bushfire risk zone requires ember-proof panel mounting on some properties — a minor extra cost of $200–400 but important for insurance compliance.

Tea Tree Gully's foothill location gives panels 0.15 extra peak sun hours in winter compared to Adelaide's flat suburban plain, adding $80/yr to generation
