Solar and batteries in Greendale.

A small farming town between Ballan and Bacchus Marsh, with a hotel, a general store and a Premier born here.

Greendale

What Greendale needs from a system.

Greendale lies about 22 kilometres north west of Bacchus Marsh and 46 kilometres east of Ballarat. It is a small town with a hotel and general store, and its neighbours are Blackwood, Ballan and Myrniong. John Cain senior, later Premier of Victoria, was born here in 1882.

Blackwood is its close neighbour, so the district takes in both open paddock and bushier blocks. The first thing to learn about any house here is whether it gets full sun or spends part of the day under trees.

Questions

Asked about solar in Greendale.

How do you decide between a roof and a ground mount?
By the shade and the cable run. If the roof is clear of trees for most of the day, it is the simple choice, and if not, a clearing in the paddock may do better. We compare the two for your block and tell you what we would pick.
How big a solar system do people put in around Greendale?
About 11 kW is the middle of what we have put in closest to Greendale, with the range running from 5.5 kW up to 22.5 kW. We size yours from your bill and what your roof can hold.
What battery sizes have you installed near Greendale?
Anything from 5.5 kWh to 54 kWh on recent jobs nearby, with about 24 kWh most typical. Your evening and overnight use sets the size.
Do you work with single phase and three phase supply near Greendale?
Yes. Our recent jobs nearby include both, and the inverter is chosen to match the supply at your place.
Who handles the connection to the power network?
We do. The connection application is part of the job.

What we do here

Everything, in Greendale.

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.
