Clean Energy Council certified·REC 22757
The leading solar retailer in Hepburn Shire and the Macedon Ranges — now designing and installing right across Victoria.
We believe that the key to a successful solar and battery installation is a personalised approach. By taking the time to understand your energy needs and consumption patterns, we can recommend a system that maximises your long-term benefits.
We design & install with the brands we trust
Accredited & approved
What we do
Solar, storage, hot water, climate and backup, specified from brands we'll still be able to service in ten years, and designed as one system so nothing falls between two trades.
Two free tools
Both take about two minutes, both run on the same engines we use in the office, and neither one ends in a sales call unless you ask for one.
Off the grid, or thinking about it
Pick what you would run and roughly where the property is. It sizes the array, battery and inverter the way we would, winter first.
On the grid, with solar or a battery
Drop in a bill or your smart meter file. We rank every plan on your network by what you would really pay, with your solar, battery and EV simulated properly.
Energy independence
Standalone power systems for properties the grid was never going to reach — farms, bush blocks, alpine country and new builds where a connection quote came back at six figures.
We size the array, the battery bank and the backup around how you actually live, not a spreadsheet average. Then we build it to survive a Victorian winter, a week of cloud and a summer of heat — and we stay on the end of the phone once it’s running.
Off-grid coverage
Where we work
We started in the Macedon Ranges and Hepburn Shire and we still live here — but our reach has grown a long way past the ranges.
Grid-connected
Rooftop solar, batteries, hot water and climate across greater Melbourne and the major regional centres.

From the Mallee to the Wimmera, the Loddon to the Goulburn, and up into the High Country around Mansfield.

A solar system is a twenty-five year purchase. We specify it, install it and support it on that basis.
We work from your real usage and consumption patterns to size the system and project the payback honestly. No oversized quote, no numbers that only work on paper.
We specify established brands with local support and real warranty backing, and favour Australian-made, owned and serviced products where we can.
Clean Energy Council certified designers and installers, with rigorous continuing professional development every year to stay on top of the technology.
We commission it, hand over monitoring, and keep watching that it performs as designed. When you call about a system we installed, you get us.
Rebates & incentives
Solar, batteries, heat-pump hot water and efficient heating upgrades all attract federal and Victorian incentives. We work out what you qualify for and make the claims for you.

How it works
Four steps, and the same person keeping you in the loop the whole way through.
01
Share a recent power bill or your address. We pull your real hourly usage rather than guessing at it.
02
We model the right system size, project the payback honestly, and lay panels out for looks as well as output.
03
Clean Energy Council certified design and installation. Function and form considered at every step.
04
We commission it, hand over monitoring, and stay in touch to check it performs exactly as designed.
Our recent work
Send us a recent power bill and your address. We’ll come back with a right-sized design and an honest payback — no pressure, no oversized quote.
