What solar actually does in Winchester
PVGIS puts Winchester at 1,037 kWh per kWp a year, which is 2.84 peak sun hours a day. A 14 panel (6.3 kWp) system here generates around 6,533 kWh a year, and on a typical system with battery roughly 55% of that is exported, worth about £725 a year at OVO's 20p export rate. Jamie's team sizes it to how you actually use energy, on a free 45 minute video call.
Yield and peak sun hours are PVGIS estimates for Winchester's own coordinates, not a regional average. Your free design refines them for your actual roof.

Generation figures are PVGIS v5.2 estimates retrieved August 2026 for the coordinates of Winchester, assuming a south-facing roof at a 35 degree pitch with no significant shading, the same assumptions as the regional figures on this site. Population is the House of Commons Library settlement classification figure. Your free design accounts for your actual orientation, pitch and shading. Export income assumes roughly 55% of generation is exported on a typical system with battery.
