Already have solar?
You've got the panels. Let's see if you're getting the most from them.
Plenty of homes have solar but no idea how much of it they're actually using. We'll analyse your existing system's real data and tell you honestly whether a battery, or a change, would help — and if it wouldn't, we'll tell you that too.

Who this is for
Already have panels and wondering what's next
Maybe the previous owner had them fitted. Maybe you did it years ago and the tariff has changed since. Either way, you're past the "should I get solar" question — the panels are on the roof and working.
The next questions are the useful ones: how much of what they make are you actually using, where's the rest going, and would a battery, or a tweak to how the system runs, put more of it to work? Those are exactly what your own data answers.

What the analysis looks at
Your existing setup, read from its real numbers
We don't need to guess how your panels are doing. Your half-hourly data shows what's being made, what's being used at home, and what's going back to the grid — and that tells us what, if anything, is worth changing.
How much you self-use
The share of your own generation you actually use at home, versus what's exported for far less than it's worth to you.
Whether a battery would help
If you're exporting a lot of surplus and buying it back at peak, storage may pay. If you're not, it may not — we size it honestly from your day.
What it's genuinely worth
A real payback figure from your own numbers for anything we'd suggest — with the assumptions shown, not hidden.
The core promise
We'll tell you if it isn't worth it
This is the easiest group for us to be straight with, because there's often nothing to sell. Sometimes the honest answer is that your system is already doing well, your self-use is high, and the best move is to leave it alone. If that's what your data says, that's what we'll tell you.
When there is something worth doing — a battery, or a change to how the system runs — you'll get a real number for it and the working behind it. No pressure, no chasing, and no same-day signature. You decide in your own time.
The analysis is free and there's no obligation. You don't need to come with us — you're welcome to take the figures and do nothing at all.
