How Wandsworth compares
Wandsworth is one of 47 Surrey towns we track, and it ranks joint 10th of 47 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 335,328, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,030 kWh per kWp a year, 2.82 peak sun hours a day averaged across the seasons, and on the 12p scenario about £247 of the year one benefit comes from solar you use yourself, with export income adding £674.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Wandsworth's own yield, and at Wandsworth's 1,030 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.

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 Wandsworth generates around 6,551 kWh a year, worth around £920 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Wandsworth's own coordinates (51.45173, -0.18438), 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 Wandsworth?
