These figures use satellite and weather data for Tarwin Lower 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 South Gippsland and Bass Coast
This is one of the cloudier parts of Victoria in winter, but it still gets good output from spring to autumn. Coastal towns such as Inverloch, Cowes and San Remo need salt-mist rated panels and corrosion-resistant mounting near the water, and many holiday homes have very different summer and winter power use.
South Gippsland and Bass Coast 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.
Salt air near the coast
Parts of Tarwin Lower 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.
Acreage, sheds and pumps
Around Tarwin Lower, 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 Tarwin Lower
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 $1,050–1,400 with a 10 kWh battery. Your own bill gives a better answer: use the calculator below.
