How Welwyn Garden City compares
Among the places we publish figures for, Welwyn Garden City is one of 27 Hertfordshire towns we track, and it ranks 11th of 27 for solar yield. It is a medium town in the House of Commons Library classification, with 52,709 residents, and its roofs see 2.80 peak sun hours a day across the year. That drives the standard 12 panel model to 6,494 kWh of generation, of which around 5,557 kWh is exported at 12p for £667 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
