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, defaulted to Nailsea's own yield, and at Nailsea's 1,014 kWh per kWp it 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.

A 12 panel, 6.36 kWp system in Nailsea generates around 6,449 kWh a year, worth around £908 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Nailsea's own coordinates (51.43041, -2.76054), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate, with the full methodology, sourcing and assumptions set out on our help page.

What does a typical solar system cost in Nailsea?

Your design call checks which applies in Nailsea before anything is booked; our G98 vs G99 guide explains the difference in full.

How long do solar panels last? 25 to 30 years, in practice
The panels outlast the inverter by a wide margin. Plan for that, not for cleaning.
Read the guide →Does a standalone battery actually pay back?
No panels means one job: buy cheap, use later. The tariff decides whether it pays.
Read the guide →Charging an EV from your own solar
Every surplus kWh is 3.6 to 5 miles. Whether that beats a 7p overnight rate is arithmetic.
Read the guide →Are heat pumps worth it? The real 2026 numbers
Electricity costs 3.3x gas per kWh. A heat pump is about 3x as efficient. The numbers nearly cancel out.

Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.

PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
