How Horsham compares
Among the places we publish figures for, Horsham is one of 33 Sussex towns we track, and it ranks 30th of 33 for solar yield. It is a medium town in the House of Commons Library classification, with 51,541 residents, and its roofs see 2.91 peak sun hours a day across the year. That drives the standard 12 panel model to 6,748 kWh of generation, of which around 5,811 kWh is exported at 12p for £697 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 Horsham's own yield, and at Horsham's 1,061 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.

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.

The strongest single box in the market, and the houses it is still wrong for.

Three phase buys 22kW charging. Most cars cannot use it, and load balancing usually solves the real problem.
