These figures use satellite and weather data for Bannockburn 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 Geelong and the Bellarine
Geelong gets a little more winter sun than Melbourne's south-east and summers are often cooled by the bay. Housing ranges from Victorian and interwar homes close to the centre, through postwar brick suburbs, to large new estates in the Armstrong Creek growth area and around Lara, Leopold and Ocean Grove.
Most of Geelong and the Bellarine 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.
Acreage, sheds and pumps
Around Bannockburn, 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.
New estates
Newer homes in Bannockburn usually have modern switchboards with room for solar. The design work is in the layout: estate roofs are often split into several smaller faces, and some estates have design guidelines for anything visible from the street.
What solar could save in Bannockburn
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 $1,000–1,400 with a 10 kWh battery. Your own bill gives a better answer: use the calculator below.
