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.
Backup when the power goes out
Properties around Halls Gap 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 Halls Gap
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.
