How City of Westminster compares
City of Westminster is one of 23 Middlesex towns we track, and it ranks joint 5th of 23 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 209,075, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,026 kWh per kWp a year, 2.81 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 £671.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to City of Westminster's own yield, and at City of Westminster'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.
