Solar and batteries in Cobaw.

A settlement under the granite Cobaw Range, with the state forest on its western slopes.

Cobaw

What Cobaw needs from a system.

Cobaw sits on Dry Creek at about 490 metres, with the Cobaw Range rising to the north. The range is mostly granite and reaches about 760 metres, and its western slopes are part of the Cobaw State Forest. The post office and school closed long ago, and few people live here now.

Houses under a range and beside a forest can lose the sun earlier in the afternoon than a map suggests. Surveying the sun carefully, early and late in the day, is how you find out what the roof will really do.

Questions

Asked about solar in Cobaw.

Does a nearby range cut the sun I get?
It can, mostly at the start and end of the day depending on which way you face. We model the horizon as well as the trees, so the figures account for the hill and not only for what is on your block.
How big a solar system do people put in around Cobaw?
About 9.5 kW is the middle of what we have put in closest to Cobaw, with the range running from 4 kW up to 21 kW. We size yours from your bill and what your roof can hold.
What battery sizes have you installed near Cobaw?
Anything from 16 kWh to 48 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 Cobaw?
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 Cobaw.

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.
