Your roof can pay the power bill.
We are installers first. Your system is sized from your actual usage and engineered in our office, then our own crew fits it, with the payback worked out on paper before a clamp touches your roof.

Where the daylight goes
Daylight in, bill out, all day long.
The roof makes power well beyond noon. It runs the house through the morning, and by mid afternoon the battery is full and the surplus is going to the grid while you are out.
MORNING
The house wakes on sun
From first light the array covers the kettle, the hot water and the morning load, so the meter barely moves before you leave.
MIDDAY
The midday export peak
Through the middle of the day the roof makes more than the house can use, and the surplus is exported to the grid for a credit on the bill.
EVENING
Battery first, then grid
After sunset the house runs on the day's stored power, and only draws from the grid once the battery is spent.
The bill shrink
The same house and the same habits, with a bill a quarter of the size.
A year of quarterly bills for a typical four-person home on a 10.2 kW system. Same house, same habits, the array running the daylight hours and the export credit trimming the rest.
The panel does not care about the weather forecast. It cares about daylight, and daylight shows up every day.

Roof read
We measure the roof, log shade hour by hour and read your last four bills. You get the yield estimate in writing.
RAILS UP
Engineering design
The panel layout and string design are drawn by the people who will install it, along with a check of your switchboard. We price the job once the design works.
PANELS ON
Install day
Rail, clamps, panels and inverter go up in one day for most homes, and the roof penetrations are photographed before they are sealed.
POWERED UP
Grid connection and handover
We lodge the grid paperwork, commission the system and walk you through the meter. Monitoring is set up before we leave.
