These figures use satellite and weather data for Warrnambool from 2005 to 2023 and already allow for heat, wiring and inverter losses. They don't know your roof: shade, pitch and the faces available decide the real number. Try the roof calculator for your own direction and pitch.
Solar in the Western District
South-west Victoria is cooler and cloudier in winter than Melbourne, but long spring and summer days still give good yearly output. Many homes sit on bigger blocks or farms, and properties a long way down rural lines can have tighter export limits, which makes using solar on site, or storing it, more valuable.
The Western District is on the Powercor network. Your distributor sets how much you can export and approves the connection; we apply for you before anything is ordered.
Salt air near the coast
Parts of Warrnambool are close to the water. Near the coast we specify panels certified for salt-mist exposure (IEC 61701) and corrosion-resistant mounting and fasteners, because standard fittings corrode faster in salt air.
Older switchboards
A lot of older housing in Warrnambool still has ceramic fuses, no safety switches or an old fibrous switchboard backing, and those have to be fixed before solar connects. We're electricians, so the switchboard is checked and any work priced in the quote. Check your switchboard.
What solar could save in Warrnambool
For a home paying $450 a quarter with someone in some days, the calculator suggests a 6.6 kW system saving about $550–750 a year, or $1,000–1,350 with a 10 kWh battery. Your own bill gives a better answer: use the calculator below.
