How Swanley compares
Small towns rarely get published solar figures, so here are the numbers for Swanley. It is one of 44 Kent towns we track, and it ranks 42nd of 44 for solar yield, a town of 17,863 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,033 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £923 of year one benefit, £247 of it from your own generation and £676 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Swanley's own yield, and at Swanley's 1,033 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 Sevenoaks; nationally, the House of Commons Library classes Swanley 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.
