Rocklyn

What Rocklyn needs from a system.

Rocklyn had a railway station on the line between Ballarat and Daylesford, opened in 1887 and closed in 1953. The trains have gone, the station has gone, and what is left is a very small rural community spread across farmland.

With so few houses, a farm here is often a long way from its neighbours, and an outage is something you deal with yourself. A battery with a proper backup circuit is worth looking at alongside the panels, to keep essentials running.

Questions

Asked about solar in Rocklyn.

What does a backup circuit actually keep running?
Whatever we wire to it, typically the fridge, freezer, lights, pumps and some power points. Running the whole house through an outage needs a much larger battery, so we agree the list first and size to that.
What size solar should I be looking at in Rocklyn?
Nearby, we have installed anything from 7.5 kW to 24 kW, with about 9.5 kW in the middle. The right size for you comes from your bill and your roof.
How big a battery do people get around Rocklyn?
The batteries we have finished nearest to Rocklyn run from about 8 kWh to 54 kWh, with about 18 kWh in the middle. What you use after dark decides yours.
Who handles the connection to the power network?
We do. The connection application is part of the job.
