What solar actually does in Romsey
Jamie holds the OVO Solar & Battery partnership for South Coast, and Romsey sits inside their SO 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 Romsey at 1,063 kWh per kWp a year, so a 14 panel (6.3 kWp) system here generates around 6,697 kWh a year.
Yield and peak sun hours are PVGIS estimates for Romsey'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 Romsey, 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.
