How Radstock compares
Small towns rarely get published solar figures, so here are the numbers for Radstock. It is one of 21 Somerset towns we track, and it ranks 21st of 21 for solar yield, a town of 10,216 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,003 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 £900 of year one benefit, £247 of it from your own generation and £653 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Radstock'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 Radstock sits with Bath and North East Somerset, 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.

Generation is modelled from PVGIS satellite data for Radstock's own coordinates (51.28974, -2.45121), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
NGED and your Radstock connection
The distribution network operator (DNO) for Radstock is National Grid Electricity Distribution (NGED), which runs the South West England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means NGED is notified within 28 days of switch-on rather than asked beforehand.
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 Radstock
A heat pump in Radstock
In December, the darkest month here, 12 panels in Radstock make about 200 kWh. That is when a heat pump runs hardest, so its running cost in Radstock comes down to the tariff and the flow temperature rather than the roof.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Radstock
Summer is where a car earns its place. In July, 12 panels in Radstock 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.
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).

Radstock solar questions
How much electricity do solar panels make in Radstock?
About 6,380 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Radstock: 1,003 kWh per kWp, or 2.75 peak sun hours a day on average. July is the strongest month, at about 790 kWh.
What does a typical solar system cost in Radstock?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Radstock, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,380 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Radstock, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Radstock. 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 Radstock?
Around £653 a year at 12p per kWh, for the roughly 5,442 kWh a 12-panel system in Radstock 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 Radstock get in December?
December is the low point: about 200 kWh from a 12-panel system in Radstock, on PVGIS data, rising to 790 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.

Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
