What solar actually does in Chesham
Greg holds the OVO Solar & Battery partnership for Thames Valley, and Chesham sits inside their HP postcode patch. You deal with a named local expert, the design happens on a free 45 minute video call, and nobody visits your home until you have decided to go ahead. PVGIS puts Chesham at 1,009 kWh per kWp a year, so a 14 panel (6.3 kWp) system here generates around 6,357 kWh a year.
Yield and peak sun hours are PVGIS estimates for Chesham'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 Chesham, 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.
