How Penzance compares
Small towns rarely get published solar figures, so here are the numbers for Penzance. It is one of 14 Cornwall towns we track, and it ranks 3rd of 14 for solar yield, a town of 14,887 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,099 kWh per kWp a year, 3.01 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £973 of year one benefit, £247 of it from your own generation and £726 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Penzance's own yield, and at Penzance's 1,099 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.
Cornwall is the planning authority covering Penzance, which the House of Commons Library classes as a small 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.
