How Horndean compares
Among the places we publish figures for, Horndean is one of 45 Hampshire towns we track, and it ranks 20th of 45 for solar yield. It is a medium town in the House of Commons Library classification, with 34,590 residents, and its roofs see 3.04 peak sun hours a day across the year. That drives the standard 12 panel model to 7,066 kWh of generation, of which around 6,129 kWh is exported at 12p for £736 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 Horndean's own yield, and at Horndean's 1,111 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 East Hampshire; nationally, the House of Commons Library classes Horndean 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.
