Solar in Seven Hills — What You Need to Know
Seven Hills sits on the ridge between Blacktown and Parramatta, one of western Sydney's transport hubs with Blacktown LGA's most significant train interchange. The suburb's 1960s–80s brick homes on 600–750m² lots are the ideal profile for western Sydney solar: large north-facing rooftops, high electricity consumption, inland sun hours advantage, and owner-occupier rates above 70%. The suburb's working-class and lower-middle-class families have electricity bills that average $2,600/year — high enough that solar ROI is obvious and immediate. Blacktown City Council has been proactive about solar education, running programs in Vietnamese, Cantonese, and Arabic that specifically target the suburb's diverse community. Seven Hills' competitive installer market — with two businesses competing specifically for suburb dominance — has kept pricing genuinely competitive, giving residents access to quality systems at prices that would normally require a bulk-buy program.
