Solar potential in Great Western
Here's what panels on a Great Western roof make, month by month, and what that could mean for your bill.
Updated November 2026 · Litmec Electrical, REC-10383
A 6.6 kW north-facing solar system in Great Western makes about 9,600 kWh a year, about the same as Melbourne: around 37 kWh a day in midsummer and 15 kWh a day in June. East or west-facing roofs make about 87% of that.
On a $450 quarterly bill, that could save roughly $600–800 a year. Great Western ranks 175th of the 429 places across Victoria we've modelled for solar output.

These figures use satellite and weather data for Great Western 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 Wimmera and Grampians
The Wimmera is dry, sunny and hot in summer, with clear winter days, so yearly output is well above Melbourne's. Farm properties, sheds and pumps are common, and homes at the end of long rural lines often face tighter export limits, which makes self-use and batteries more important.
The Wimmera 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 Great Western, 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 Great Western
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.
