Keep your sunshine for later.
The sun clocks off around teatime. Your house doesn't. A battery catches the day's spare sunshine and spends it on supper, bath time and the ten o'clock news.
Sized to your evenings.
Not the biggest battery we can sell you. The right one for how your house actually spends its nights, worked out from your real usage.
Proper batteries, fitted properly
Sigenergy, FoxESS and Ecoflow units on a tidy wall, wired to BS 7671 by NICEIC electricians. Garage, utility room or a quiet corner; a very contented hum at most.
An evening on the battery.
Drag the moon across the evening and watch the battery carry the house: supper, telly, lights, the lot. The grid only steps in if the battery runs dry.

June: the battery went to bed full on today's sunshine. December: part solar, part cheap overnight rate, which is the trick that makes winter work.
Retrofits, from £3,500
Thousands of West Country roofs got panels years ago and still give the surplus away for pennies. A retrofit battery catches it instead: same roof, same panels, much better arithmetic. No scaffold, one tidy day.
Out of sight, on the job
The battery lives where you won't trip over it and works while you're watching the telly. The app shows the whole story live: what the roof made, what the battery holds, what the house is drinking.
Fitted, humming, forgotten.
Real installs from the van's camera roll. Drag through the pile.
Drag to rummage
"Tidy, punctual and clearly knew their stuff. Explained the export tariff without once making me feel dim. The app is dangerously addictive."
"40kW of panels, 30kWh of batteries and a three-phase hybrid inverter, delivered without fuss. The site barely noticed they were here."
Fair questions.
What size battery do I need?+
Whatever your evenings actually use, usually somewhere between 5 and 10 kWh for a family house. We work it out from your real bills at the estimate stage rather than guessing generously and charging you for the guess.
How long do batteries last?+
The units we fit carry warranties of around ten years, and they're designed for thousands of charge cycles. Like the panels, they fade gently rather than stopping dead, and the app shows you exactly how yours is doing.
Will it power the house in a power cut?+
Only if we set it up for that. Standard installs shut down in a cut for the safety of anyone working on the lines. Some systems offer backup circuits as an extra, and we'll tell you honestly whether it's worth it for how rarely your area loses power.
Does a battery make sense without solar?+
Sometimes. On the right tariff it can charge cheap overnight and spend that at peak prices. The maths is tighter than with panels, so this is one where we run your numbers and give you a straight yes or no.
Is it safe in a garage?+
Yes, fitted correctly. The units we install are certified for indoor mounting, we follow the manufacturer's clearances and current wiring regs, and it's all signed off by an NICEIC-approved contractor. That's the boring paperwork doing its job.
Keep tonight's telly on today's sun.
Three details in, honest numbers back, with the battery sums shown both ways so you can judge it on arithmetic.
