Savings calculator
Work it out before anybody rings you
Three numbers is all it takes. You get a recommended size, the yearly saving, the VAT you are not paying and what the roof makes month by month. One button drops the whole lot into an enquiry.
Step 1 — your numbers
What you know about the house
What the sums are based on
- 1 kWp makes about 1,000 kWh a year in this part of Devon, facing south at around 35°.
- Electricity at 26p a unit, and 15p a unit for what you export under the Smart Export Guarantee.
- Fitted price: £2,400 base (scaffolding, design, DNO application, roof kit, testing and commissioning) + £700 per kWp + £450 per kWh of battery.
- There is no grant for an ordinary household — the Feed-in Tariff closed in 2019. What you do save is VAT: solar and battery installations are zero-rated until 31 March 2027, which is a fifth off the whole job.
- Payback is worked out without future rises in the price of electricity. If prices go up, it pays back sooner than this figure says.

Put your usage in on the left and the answer appears here.
It also saves roughly — of carbon dioxide a year against buying the same units from the grid.
This is an estimate, not a quote. Firm numbers come after somebody has been on the roof — shading, the state of the timbers, the fuse and how you actually use electricity during the day all move it.
What we do
Four things, done properly
We do not fit heat pumps or insulation. We stick to what we have tried on our own roofs.
Battery storage
LFP batteries from 5 to 25 kWh, retro-fitted to an existing array if you already have one. We can wire in backup for a power cut too.
from £4,90010 kWh including the wiring
Commercial systems
Units, workshops and guest houses. We look at daytime load, the half-hourly data and what the DNO will allow on your supply.
from £23,40030 kWp, price depends on the roof
Chargers and hot water
Charging the car on surplus only, or diverting it into the immersion. The two cheapest ways of using your own electricity.

About us
Ten years on Devon roofs
We started in 2016 as two electricians in Crediton. There are three fitting teams now, our own access platform and a stores unit on the Exeter road — so when an inverter fails you are not waiting three weeks for a delivery.
There is no call centre and no commission-paid “energy advisers”. The person who surveys the roof is the one who will be standing on it, and if it does not stack up we say so. We have turned about forty jobs down that way — mostly shaded roofs and houses using under 2,000 units a year.

Working together
From the first phone call to the first unit generated
The whole thing takes about six weeks, and you need to be there twice: for the survey and for the fitting.
Enquiry and roof survey
We answer within two working days and arrange a survey. Up on the roof, measured, photographed, and a look at the consumer unit. Free and no obligation.

One page with the final price. Once it is signed we put in the DNO application and book the scaffolding.

What to expect
Three things worth hearing before you sign anything
December and January make about 5 % of the year. Anybody who shows you a payback figure without saying that is hoping you will not notice. The roof earns its money between March and September.
There is no grant. The Feed-in Tariff closed in 2019. What you get instead is 0 % VAT until March 2027 and an export payment through the Smart Export Guarantee, which needs an MCS certificate — ours.
Shade is the thing that kills a system. A single chimney or a neighbour’s conifer across two panels can cost you a fifth of the output. We measure it on the survey and, if it is bad enough, we say don’t.
Common questions
What people ask us most
Is there enough sun in Devon to make it worth doing?
Yes. The south-west gets about 1,000 kWh a year from each kWp, which is as good as anywhere in the country, and panels are actually more efficient when it is cool. The part nobody mentions: December and January between them produce about 5 % of the year’s total. That is worth knowing in advance rather than being surprised by it.
Do I have to have a battery?
No. Without one you will use about 30 % of what the roof makes and export the rest at roughly half the price you buy it for. A battery turns that round and gets you to 60–70 %. Payback barely moves — a battery costs more but saves more. Switch it on and off in the calculator above and see.
How long does the DNO connection take?
Up to 3.68 kW per phase it is a G98 notification, which we send after the job. Anything larger needs a G99 application first, and the network operator has up to forty-five working days — in practice three to five weeks. We can fit it before that comes back, we just cannot switch it on. The paperwork is ours.
What happens if I move or sell the house?
The system belongs to the building and goes with it. The buyer’s solicitor will ask for the MCS certificate, the electrical certificate and the DNO paperwork — we keep copies and send them out again free of charge. The new owner sets up their own Smart Export Guarantee tariff with whichever supplier they choose.
What about keeping the house running in a power cut?
An ordinary system shuts itself down in a power cut, for the safety of anybody working on the network. To keep going you need a hybrid inverter with a backup output and a battery — about £1,400 more, and we agree beforehand which circuits it feeds. Usually the boiler, the fridge, the lights and the broadband.
