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.
Serious batteries, tidily fitted
Sigenergy, FoxESS and Ecoflow units on a tidy wall, wired to BS 7671 by NICEIC electricians. Garage, utility room, or straight onto an outside wall if space indoors is tight. A very contented hum at most.

- Charges cheap overnight in winter on a smart tariff
- Typically a 10-year warranty on the unit
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 South West 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.
- Works with most existing arrays, whoever fitted them
- We health-check your setup before quoting anything
- Typically 5 to 10 kWh of storage for a family house
- One tidy day, no scaffold
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.
- Lives in the garage, a utility or outside on a wall
- Outdoor units are weatherproof and self-heating, so a cold snap doesn't cost you capacity
- Makes a very contented hum, and that is about it
- The app set up and explained before we leave
- So you never have to ring the support line yourself
Fitted, humming, forgotten.
Real installs from the van's camera roll. Drag through the pile.
Drag to rummage
"Dan came to do an initial assessment and was able to answer our questions and concerns. He kept us informed regarding starting date. We were clear about the costs from the start. They've done amazing job, very neat and tidy. Dan also helped set up the app so we didn't have to deal with the support ourselves."
"Dan was professional throughout and the whole process was very smooth. He organised for scaffolding to go up the week before our install and then he and his dad Chris were on site together for four days. This was followed by a clear handover pack."
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.
