How Tewkesbury compares
Small towns rarely get published solar figures, so here are the numbers for Tewkesbury. It is one of 24 Gloucestershire towns we track, and it ranks 18th of 24 for solar yield, a town of 14,819 people in the House of Commons Library settlement data. PVGIS gives its roofs 994 kWh per kWp a year, 2.72 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £893 of year one benefit, £247 of it from your own generation and £646 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Tewkesbury'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.
Tewkesbury is its own local planning authority area, and its 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 Tewkesbury
Tewkesbury 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.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Tewkesbury
A heat pump in Tewkesbury
In December, the darkest month here, 12 panels in Tewkesbury make about 210 kWh. That is when a heat pump runs hardest, so its running cost in Tewkesbury 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 Tewkesbury
Summer is where a car earns its place. In July, 12 panels in Tewkesbury make about 780 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Tewkesbury solar questions
How much electricity do solar panels make in Tewkesbury?
About 6,320 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Tewkesbury: 994 kWh per kWp, or 2.72 peak sun hours a day on average. July is the strongest month, at about 780 kWh.
What does a typical solar system cost in Tewkesbury?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Tewkesbury, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,320 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Tewkesbury, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Tewkesbury. 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 happens to the solar I do not use in Tewkesbury?
Around £646 a year at 12p per kWh, for the roughly 5,385 kWh a 12-panel system in Tewkesbury exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Tewkesbury get in December?
December is the low point: about 210 kWh from a 12-panel system in Tewkesbury, on PVGIS data, rising to 780 kWh in July. From November to February the same system makes about 1,070 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Tewkesbury 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 Tewkesbury |
|---|---|---|
| Tewkesbury | 994 | this town |
| Bishop's Cleeve | 987 | −7 kWh |
| Cheltenham | 991 | −3 kWh |
| Innsworth | 983 | −11 kWh |
| Pershore | 1,002 | +8 kWh |
| Brockworth | 990 | −4 kWh |
| Gloucester | 980 | −14 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.
