How London Colney compares
Small towns rarely get published solar figures, so here are the numbers for London Colney. It is one of 27 Hertfordshire towns we track, and it ranks joint 9th of 27 for solar yield, a town of 8,547 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,022 kWh per kWp a year, 2.80 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £915 of year one benefit, £247 of it from your own generation and £668 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to London Colney's own yield, and at London Colney's 1,022 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.
Planning applications here go through St Albans; nationally, the House of Commons Library classes London Colney 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.
