How Letchworth compares
Among the places we publish figures for, Letchworth is one of 27 Hertfordshire towns we track, and it ranks joint 12th of 27 for solar yield. It is a medium town in the House of Commons Library classification, with 34,603 residents, and its roofs see 2.79 peak sun hours a day across the year. That drives the standard 12 panel model to 6,481 kWh of generation, of which around 5,544 kWh is exported at 12p for £665 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 Letchworth's own yield, and at Letchworth's 1,019 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.
Letchworth sits within North Hertfordshire, its local planning authority, and the House of Commons Library classes it as a medium 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.
