These figures use satellite and weather data for Castlemaine 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 Bendigo, Loddon and Campaspe
North of the Divide the climate is drier and sunnier than Melbourne, with hot summers that drive air-conditioning use exactly when panels produce most. Goldfields-era homes, postwar brick houses and fast-growing estates are all common, and many properties along the Campaspe and Murray are on acreage.
Bendigo, Loddon and Campaspe are on the Powercor network. Your distributor sets how much you can export and approves the connection; we apply for you before anything is ordered.
Heritage areas
Parts of Castlemaine are under heritage overlays administered by Mount Alexander Shire. Panels on rear and side roof faces that can't be seen from the street are usually the simplest route. We check the overlay for your address before quoting. Solar on heritage homes.
Older switchboards
A lot of older housing in Castlemaine 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 Castlemaine
For a home paying $450 a quarter with someone in some days, the calculator suggests a 6.6 kW system saving about $600–800 a year, or $1,000–1,400 with a 10 kWh battery. Your own bill gives a better answer: use the calculator below.
