How Devizes compares
Small towns rarely get published solar figures, so here are the numbers for Devizes. It is one of 20 Wiltshire towns we track, and it ranks joint 8th of 20 for solar yield, a town of 19,923 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,025 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 £917 of year one benefit, £247 of it from your own generation and £670 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Devizes's own yield, and at Devizes's 1,025 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.
Wiltshire is the planning authority covering Devizes, which the House of Commons Library classes 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 Devizes generates around 6,519 kWh a year, worth around £916 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Devizes's own coordinates (51.35196, -1.98559), 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 Devizes?

How to clean solar panels, and whether you need to at all
Cleaning is oversold and pigeon mesh is undersold. The numbers behind both.

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.

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