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.

Country properties
Sheds, pumps, long cable runs and rural supply lines all change how a system should be designed, and a battery only keeps the power on in an outage if it's set up for backup. See solar for rural properties and battery backup for outages.
