How Grantham compares
Among the places we publish figures for, Grantham is one of 22 Lincolnshire towns we track, and it ranks 16th of 22 for solar yield. It is a medium town in the House of Commons Library classification, with 45,356 residents, and its roofs see 2.78 peak sun hours a day across the year. That drives the standard 12 panel model to 6,443 kWh of generation, of which around 5,506 kWh is exported at 12p for £661 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Grantham's own yield, and at Grantham's 1,013 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.

What does a typical solar system cost in Grantham?
