These figures use satellite and weather data for Longwarry 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 West Gippsland and the Latrobe Valley
Gippsland winters are cloudier than Melbourne's, so the gap between summer and winter output is wider, and a system is usually sized on the yearly figure rather than on June. Homes range from postwar brick houses in the Latrobe Valley towns to new estates around Warragul and Drouin and farm properties in between.
West Gippsland and the Latrobe Valley are on the AusNet Services network. Your distributor sets how much you can export and approves the connection; we apply for you before anything is ordered.
Acreage, sheds and pumps
Around Longwarry, many properties have sheds, bores or pumps and long distances between buildings. Panels can go on a shed roof or a ground frame, cable runs are designed to keep voltage drop within the wiring rules, and daytime pumping is one of the cheapest ways to use your own solar. Some rural lines (including SWER lines) have tight export limits, which we confirm before you commit. Solar for rural properties.
What solar could save in Longwarry
For a home paying $450 a quarter with someone in some days, the calculator suggests a 6.6 kW system saving about $550–800 a year, or $1,000–1,350 with a 10 kWh battery. Your own bill gives a better answer: use the calculator below.
