Solar in Kogarah — What You Need to Know
Kogarah's housing stock is a challenging but rewarding solar landscape. The mix of 1920s–60s terrace houses and post-war brick homes on small lots means roof area is at a premium. Many terrace properties have north-facing rear slopes — these can host 6–10 panels effectively. Flat concrete roofs on 1950s units require tilt-frame mounting at extra cost ($200–400). Georges River Council has a progressive sustainability agenda and streamlined solar approvals. Kogarah's proximity to St George Hospital creates a large shift-worker demographic — daytime occupancy is higher than average, improving solar self-consumption rates significantly.
