How Darwen compares
Among the places we publish figures for, Darwen is one of 109 Lancashire towns we track, and it ranks joint 81st of 109 for solar yield. It is a medium town in the House of Commons Library classification, with 28,246 residents, and its roofs see 2.41 peak sun hours a day across the year. That drives the standard 12 panel model to 5,584 kWh of generation, of which around 4,647 kWh is exported at 12p for £558 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 Darwen's own yield, and at Darwen's 878 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 Blackburn with Darwen; nationally, the House of Commons Library classes Darwen 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.
