Solar and batteries in Darley.

A fast growing suburb of Bacchus Marsh, between the Lerderderg River and the Western Freeway.

Darley

What Darley needs from a system.

Darley lies directly north of Bacchus Marsh's centre across the Western Freeway, on the rural and urban fringe, with the Lerderderg River to the east and Lerderderg State Park to the north. It began as a farming settlement in 1838 and has grown rapidly with new housing estates. Council Trench, a small outcrop of Triassic rock, is a geological curiosity, unique in Victoria.

New estates mean newer roofs with clear aspects and modern switchboards, which makes this some of the more straightforward country for solar. The discussion is usually about battery size, EV charging and how to handle summer heat, since Bacchus Marsh is warmer than the ranges.

Questions

Asked about solar in Darley.

Does a new estate house need anything special for solar?
Mostly it needs the roof checked for space and the estate's design rules read for any restrictions. Newer switchboards are usually ready, and the work is mainly matching the system to the household.
How big a solar system do people put in around Darley?
About 14.5 kW is the middle of what we have put in closest to Darley, with the range running from 8 kW up to 19.5 kW. We size yours from your bill and what your roof can hold.
What battery sizes have you installed near Darley?
Anything from 16 kWh to 33 kWh on recent jobs nearby, with about 23.5 kWh most typical. Your evening and overnight use sets the size.
Do you work with single phase and three phase supply near Darley?
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.
