Solar potential in Deans Marsh
What solar would make on your Deans Marsh roof, what it could save, and what to check before you buy.
Updated November 2026 · Litmec Electrical, REC-10383
A 6.6 kW north-facing solar system in Deans Marsh makes about 9,200 kWh a year, about 3% less than Melbourne: around 34 kWh a day in midsummer and 15 kWh a day in June. East or west-facing roofs make about 85% of that.
On a $450 quarterly bill, that could save roughly $550–800 a year. Deans Marsh ranks 366th of the 429 places across Victoria we've modelled for solar output.

These figures use satellite and weather data for Deans Marsh 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 Surf Coast and the Otways
Coastal towns here get cool, cloudier winters, especially towards the Otways, so winter output is lower than inland and the value of solar is mostly made from spring to autumn. Salt air along the coast and the bushfire-prone bushland around many towns both shape how a system is specified.
The Surf Coast and Colac districts 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.
Acreage, sheds and pumps
Around Deans Marsh, 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.
Backup when the power goes out
Properties around Deans Marsh can be on long rural lines that are exposed to storms and bushfire. Standard solar switches off in a blackout; a battery with backup wiring keeps the fridge, lights, internet and water pump running. How battery backup works.
What solar could save in Deans Marsh
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.
