Pentland Hills

What Pentland Hills needs from a system.

Pentland Hills is a rural locality about 90 kilometres west of Melbourne, on the main road corridor to Ballarat. Its name was used for the post office that opened in 1858, which was renamed Myrniong in 1872, and the name has stuck to the district around it.

It is farming country with a modest population, close enough to Bacchus Marsh and Ballan for services. The decision is mostly about the loads on the farm and how much of the roof or the ground to use.

Questions

Asked about solar in Pentland Hills.

How many panels will my roof hold?
It depends on the usable area, the pitch, the aspect and any obstructions such as vents and skylights. We lay out the panels on a plan after the site visit and show you the options before you commit.
How big a solar system do people put in around Pentland Hills?
About 11.5 kW is the middle of what we have put in closest to Pentland Hills, with the range running from 8 kW up to 18.5 kW. We size yours from your bill and what your roof can hold.
What battery sizes have you installed near Pentland Hills?
Anything from 25 kWh to 48 kWh on recent jobs nearby, with about 32.5 kWh most typical. Your evening and overnight use sets the size.
Do you work with single phase and three phase supply near Pentland Hills?
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.
