Solar in the Mallee
The Mallee is the sunniest and hottest part of Victoria, so a kilowatt of panels here makes noticeably more than in Melbourne. Heat cuts panel efficiency on the hottest days and summer air-conditioning loads are high, so system design is about matching big daytime output to big daytime use.
The Mallee 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.
