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.

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.
