How Stonehouse compares
Small towns rarely get published solar figures, so here are the numbers for Stonehouse. It is one of 24 Gloucestershire towns we track, and it ranks 11th of 24 for solar yield, a town of 9,749 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,004 kWh per kWp a year, 2.75 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £901 of year one benefit, £247 of it from your own generation and £654 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Stonehouse's own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Any planning application in Stonehouse sits with Stroud, and its official House of Commons Library settlement class is small town.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

The network operator for Stonehouse
The distribution network operator (DNO) for Stonehouse is National Grid Electricity Distribution (NGED), which runs the West Midlands licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, NGED only has to be told within 28 days after the system is commissioned.
Above that, G99 means applying before the work is booked. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Heat pumps and EV charging in Stonehouse
A heat pump in Stonehouse
In December, the darkest month here, 12 panels in Stonehouse make about 210 kWh. That is when a heat pump runs hardest, so its running cost in Stonehouse comes down to the tariff and the flow temperature rather than the roof.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Stonehouse
Stonehouse's July output, about 800 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Solar in Stonehouse: your questions answered
How much electricity do solar panels make in Stonehouse?
About 6,390 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Stonehouse: 1,004 kWh per kWp, or 2.75 peak sun hours a day on average. July is the strongest month, at about 800 kWh.
Is solar more expensive in Stonehouse?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Stonehouse, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,390 kWh a year here, which is what drives payback.
Which DNO covers Stonehouse, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Stonehouse. A home system of up to 3.68kW per phase is notified to NGED within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.
What could I earn from exporting in Stonehouse?
On the 12p export scenario, a 12-panel system in Stonehouse sends about 5,449 kWh a year to the grid, worth around £654. The export rates table compares what each supplier pays.
How much solar does Stonehouse get in December?
December is the low point: about 210 kWh from a 12-panel system in Stonehouse, on PVGIS data, rising to 800 kWh in July. From November to February the same system makes about 1,050 kWh in total, which is why a battery charged off-peak does more of the work in winter.
