How Winchester compares
Among the places we publish figures for, Winchester is one of 45 Hampshire towns we track, and it ranks joint 36th of 45 for solar yield. It is a medium town in the House of Commons Library classification, with 50,588 residents, and its roofs see 2.84 peak sun hours a day across the year. That drives the standard 12 panel model to 6,595 kWh of generation, of which around 5,659 kWh is exported at 12p for £679 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 Winchester's own yield, and at Winchester's 1,037 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.
Winchester sits within Winchester, its local planning authority, and the House of Commons Library classes it 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.

A 12 panel, 6.36 kWp system in Winchester generates around 6,595 kWh a year, worth around £926 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Winchester's own coordinates (51.06268, -1.32343), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate, with the full methodology, sourcing and assumptions set out on our help page.

Common questions about solar in Winchester

What does a typical solar system cost in Winchester?
A typical 12 panel, 6.36 kWp system in Winchester costs around £6,360 installed, at £1,000 per kWp before any battery.
Would a system in Winchester need a G99 application?
Most home solar and battery systems qualify for the simpler G98 notification, made to the network operator (DNO) after installation rather than before. A minority, usually larger systems, need the fuller G99 process instead. Your design call checks which applies in Winchester before anything is booked; our G98 vs G99 guide explains the difference in full.

Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.

PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
