How Thornbury compares
Small towns rarely get published solar figures, so here are the numbers for Thornbury. It is one of 24 Gloucestershire towns we track, and it ranks joint 1st of 24 for solar yield, a town of 14,381 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,024 kWh per kWp a year, 2.81 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £916 of year one benefit, £247 of it from your own generation and £669 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Thornbury's own yield, and at Thornbury's 1,024 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.
Any planning application in Thornbury sits with South Gloucestershire, 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.

Do solar panels need direct sunlight? Not really, and here is why
No. Solar cells respond to light hitting them, not to a clear line of sight to the sun.

The CT clamp, the surplus tracking and the 1.4kW floor that catches people out.
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.
Read the guide →The price cap explained, and what it does to solar payback
The cap limits unit rates, not bills. That changes what solar payback means.

A logo proves nothing. Certification is business specific, technology specific and checkable.

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