How Nailsea compares
Small towns rarely get published solar figures, so here are the numbers for Nailsea. It is one of 21 Somerset towns we track, and it ranks 17th of 21 for solar yield, a town of 16,313 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,014 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 £908 of year one benefit, £247 of it from your own generation and £661 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Nailsea'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 North Somerset; nationally, the House of Commons Library classes Nailsea 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.

The network operator for Nailsea
Nailsea sits in National Grid Electricity Distribution's South West England licence area, so NGED is the network operator (DNO) any solar panels or battery here are registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to NGED within 28 days of commissioning, with no prior approval.
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 Nailsea
A heat pump in Nailsea
Heating demand peaks when solar is weakest. In Nailsea, a 12-panel system makes about 210 kWh in December and 240 kWh in January, a fraction of its 800 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Nailsea
Summer is where a car earns its place. In May, 12 panels in Nailsea make about 800 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.
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 Nailsea: your questions answered
How much electricity do solar panels make in Nailsea?
About 6,450 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Nailsea: 1,014 kWh per kWp, or 2.78 peak sun hours a day on average. May is the strongest month, at about 800 kWh.
What does a typical solar system cost in Nailsea?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Nailsea, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,450 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Nailsea, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Nailsea. 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 Nailsea?
Around £661 a year at 12p per kWh, for the roughly 5,512 kWh a 12-panel system in Nailsea 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 Nailsea get in December?
December is the low point: about 210 kWh from a 12-panel system in Nailsea, on PVGIS data, rising to 800 kWh in May. From November to February the same system makes about 1,060 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Nailsea 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 Nailsea |
|---|---|---|
| Nailsea | 1,014 | this town |
| Portishead | 1,019 | +5 kWh |
| Yatton | 1,016 | +2 kWh |
| Clevedon | 1,045 | +31 kWh |
| Bristol | 1,021 | +7 kWh |
| Filton | 1,014 | level |
| Weston-super-Mare | 1,053 | +39 kWh |
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.

No panels means one job: buy cheap, use later. The tariff decides whether it pays.
