How Stanwell compares
Small towns rarely get published solar figures, so here are the numbers for Stanwell. It is one of 23 Middlesex towns we track, and it ranks joint 5th of 23 for solar yield, a town of 12,629 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,026 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 £918 of year one benefit, £247 of it from your own generation and £671 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Stanwell's own yield, and at Stanwell's 1,026 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.
Spelthorne is the planning authority covering Stanwell, 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 Stanwell generates around 6,525 kWh a year, worth around £917 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Stanwell's own coordinates (51.45331, -0.47404), 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 Stanwell?

Would a system in Stanwell need a G99 application?
Most home solar and battery systems qualify for the simpler G98 notification, made to the network operator (DNO) after installation rather than before. A minority, usually larger systems, need the fuller G99 process instead. Your design call checks which applies in Stanwell before anything is booked; our G98 vs G99 guide explains the difference in full.

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

Home off-peak charging costs a fraction of the public price. The arithmetic, and the tariff it depends on.
