How Daventry compares
Among the places we publish figures for, Daventry is one of 16 Northamptonshire towns we track, and it ranks 16th of 16 for solar yield. It is a medium town in the House of Commons Library classification, with 28,179 residents, and its roofs see 2.77 peak sun hours a day across the year. That drives the standard 12 panel model to 6,436 kWh of generation, of which around 5,500 kWh is exported at 12p for £660 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 Daventry's own yield, and at Daventry's 1,012 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.
Any planning application in Daventry sits with West Northamptonshire, and its official House of Commons Library settlement class is 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.
