Solar in Penrith — What You Need to Know
Penrith holds the record for Sydney's highest recorded temperatures, with summer days regularly exceeding 40°C. This extreme heat reduces standard panel output by 10–15%, making temperature coefficient a critical selection factor. Choose panels rated below -0.30%/°C. On the flip side, Penrith's western position means long afternoon sun exposure and some of Sydney's highest annual irradiance. Low tree canopy and wide suburban blocks mean almost every home has excellent unobstructed roof access. Penrith Council actively supports solar and has no heritage overlays in residential areas.
