These figures use satellite and weather data for Longwood 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 Goulburn Valley and Mitchell Shire
Northern Victoria has hot, dry summers and some of the best solar output in the state. Air conditioning drives summer bills, irrigation and farm loads are common on the outskirts of towns, and new estates are growing quickly around Shepparton, Wallan and Kilmore.
This area is split between the Powercor and AusNet Services networks; your bill shows which one you are on. 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 Longwood, 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 Longwood
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.
