Software
The software that sizes your system from real data — not a guess.
Every system we design starts in software that reads your own half-hourly electricity data and models what solar, a battery or a heat pump would actually do in your home. It's the difference between a number scaled off your annual bill and a system built around how you really use power.

What it does
It models your home, not a category
Give it your half-hourly data — the readings your smart meter already takes — and it builds a picture of exactly when and how hard you draw power across a whole year. Then it models how a proposed system would perform against that real profile: how much it would generate, how much you'd actually use on site, what you'd export, and a genuine payback.
It's the engine behind the free analysis. Same data, same maths, whether you go ahead or not.
- Reads your real half-hourly usage, not an annual estimate
- Models generation, self-use, export and payback across a full year
- Sizes solar, battery and heat pumps to your actual load
- Shows the working — including when the numbers don't stack up
(real analysis output — to add)
Why it matters
Most quotes are a guess. Ours are worked out
Size a system off your annual kWh and you're assuming an average home. But your usage shape decides everything — two homes with the same annual total can need very different systems. The software sizes from the shape, so you're not paying for capacity you'll never use, or falling short of what you need.
After install
It keeps checking the model was right
The job isn't done when the kit is on the wall. The same software monitors how your system actually performs against what the analysis projected — so if something drifts or underperforms, it gets spotted and dealt with, not left for you to notice on a bill months later.

Why we start with your half-hourly data, not your annual bill
Your annual kWh hides the one thing that decides what system you actually need: the shape of how you use power.
