Solar and batteries in Wallace.

A small farming township between Ballarat and Ballan, established in the 1880s.

Wallace

What Wallace needs from a system.

Wallace lies about 19 kilometres east of Ballarat and 18 west of Ballan, in farming country. The township was established in the 1880s, its post office opened in 1885 and closed in 1993, and the Wallace Hotel is the one landmark that stands out. Edmond Hogan, twice Premier of Victoria in the 1920s, was born here.

Springbank and Bungaree are close neighbours, and the surrounding country is farmland. Open land is an advantage for solar, and older farmhouses are common in country like this, so the switchboard often needs looking at before anything else.

Questions

Asked about solar in Wallace.

What happens if the switchboard needs work first?
We quote the board upgrade as its own step, so you can see what it involves, and do it before the solar goes on. It is a common first job on older farmhouses and it makes the rest of the system safer.
What size solar system suits a home around Wallace?
The systems we have finished nearest to Wallace run from about 7.5 kW to 20.5 kW, and the middle of that is about 10 kW. Your bill and your roof set the real number.
What battery sizes have you installed near Wallace?
Anything from 16.5 kWh to 54 kWh on recent jobs nearby, with about 22 kWh most typical. Your evening and overnight use sets the size.
Who handles the connection to the power network?
We do. The connection application is part of the job.

What we do here

Everything, in Wallace.

We design the whole system rather than just the panels: solar, storage, hot water, climate and the electrical behind it. One design, one point of contact, and one company carrying the warranty afterwards.
