How South Merstham compares
Small towns rarely get published solar figures, so here are the numbers for South Merstham. It is one of 47 Surrey towns we track, and it ranks joint 12th of 47 for solar yield, a town of 9,887 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,029 kWh per kWp a year, 2.82 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £920 of year one benefit, £247 of it from your own generation and £673 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to South Merstham's own yield, and at South Merstham's 1,029 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 Reigate and Banstead; nationally, the House of Commons Library classes South Merstham 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.
