How Cam compares
Small towns rarely get published solar figures, so here are the numbers for Cam. It is one of 24 Gloucestershire towns we track, and it ranks joint 15th of 24 for solar yield, a town of 8,572 people in the House of Commons Library settlement data. PVGIS gives its roofs 998 kWh per kWp a year, 2.73 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £896 of year one benefit, £247 of it from your own generation and £649 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Cam'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.
Planning applications here go through Stroud; nationally, the House of Commons Library classes Cam as a 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.

NGED and your Cam connection
Cam is served by National Grid Electricity Distribution (NGED): the town's centre falls inside its West Midlands licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to NGED within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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 Cam
A heat pump in Cam
In December, the darkest month here, 12 panels in Cam make about 210 kWh. That is when a heat pump runs hardest, so its running cost in Cam comes down to the tariff and the flow temperature rather than the roof.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Cam
Cam's July output, about 790 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Solar in Cam: your questions answered
How much electricity do solar panels make in Cam?
About 6,350 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Cam: 998 kWh per kWp, or 2.73 peak sun hours a day on average. July is the strongest month, at about 790 kWh.
Is solar more expensive in Cam?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Cam, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,350 kWh a year here, which is what drives payback.
Which DNO covers Cam, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Cam. 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 Cam?
On the 12p export scenario, a 12-panel system in Cam sends about 5,411 kWh a year to the grid, worth around £649. The export rates table compares what each supplier pays.
How much solar does Cam get in December?
December is the low point: about 210 kWh from a 12-panel system in Cam, on PVGIS data, rising to 790 kWh in July. From November to February the same system makes about 1,040 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Cam compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Cam |
|---|---|---|
| Cam | 998 | this town |
| Dursley | 991 | −7 kWh |
| Stonehouse | 1,004 | +6 kWh |
| Stroud | 998 | level |
| Lydney | 1,024 | +26 kWh |
| Thornbury | 1,024 | +26 kWh |
| Quedgeley and Hardwicke | 999 | +1 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
