Bullengarook

What Bullengarook needs from a system.

Bullengarook lies about fourteen kilometres west of Gisborne and nineteen north of Bacchus Marsh, at roughly 484 metres. Mount Bullengarook and the Lerderderg State Park are to the south, and the headwaters of Coimadai Creek start there. It was settled around 1850 and slate and gold were mined, and it has no shops, only a recreation reserve and a CFA station.

The bush and the creeks give the district its character, and the equestrian properties give it its loads. Shade from tall gums and the distance to the nearest shop mean most households think carefully about fire, water and power.

Questions

Asked about solar in Bullengarook.

Do bushfire rules affect where I can put a battery?
They can. Council and CFA guidance may influence the building and the area around it, and manufacturers set clearances for batteries. We plan placement with both in mind and confirm it with you before installation.
What size solar system suits a home around Bullengarook?
The systems we have finished nearest to Bullengarook run from about 4 kW to 22.5 kW, and the middle of that is about 11 kW. Your bill and your roof set the real number.
What size battery suits a home near Bullengarook?
About 24 kWh is the middle of what we have fitted closest to Bullengarook, and the range goes from 5.5 kWh to 48 kWh. We work yours out from your evening and overnight use.
Do you work with single phase and three phase supply near Bullengarook?
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.
