How Shepton Mallet compares
Small towns rarely get published solar figures, so here are the numbers for Shepton Mallet. It is one of 21 Somerset towns we track, and it ranks joint 15th of 21 for solar yield, a town of 10,118 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,015 kWh per kWp a year, 2.78 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £909 of year one benefit, £247 of it from your own generation and £662 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Shepton Mallet'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 Somerset; nationally, the House of Commons Library classes Shepton Mallet 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 Shepton Mallet connection
The distribution network operator (DNO) for Shepton Mallet is National Grid Electricity Distribution (NGED), which runs the South West England 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.
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 Shepton Mallet
A heat pump in Shepton Mallet
In December, the darkest month here, 12 panels in Shepton Mallet make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Shepton Mallet 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 Shepton Mallet
Summer is where a car earns its place. In July, 12 panels in Shepton Mallet make about 790 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.

Shepton Mallet solar questions
How much electricity do solar panels make in Shepton Mallet?
About 6,460 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Shepton Mallet: 1,015 kWh per kWp, or 2.78 peak sun hours a day on average. July is the strongest month, at about 790 kWh.
What does a typical solar system cost in Shepton Mallet?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Shepton Mallet, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,460 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Shepton Mallet, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Shepton Mallet. 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 Shepton Mallet?
Around £662 a year at 12p per kWh, for the roughly 5,519 kWh a 12-panel system in Shepton Mallet 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 Shepton Mallet get in December?
December is the low point: about 220 kWh from a 12-panel system in Shepton Mallet, on PVGIS data, rising to 790 kWh in July. From November to February the same system makes about 1,090 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Shepton Mallet 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 Shepton Mallet |
|---|---|---|
| Shepton Mallet | 1,015 | this town |
| Wells | 1,015 | level |
| Midsomer Norton | 1,005 | −10 kWh |
| Glastonbury | 1,033 | +18 kWh |
| Radstock | 1,003 | −12 kWh |
| Street | 1,032 | +17 kWh |
| Frome | 1,008 | −7 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.
