What solar actually does in Milford Haven
Keiron holds the OVO Solar & Battery partnership for South Wales, and Milford Haven sits inside their SA 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 Milford Haven at 1,095 kWh per kWp a year, so a 14 panel (6.3 kWp) system here generates around 6,899 kWh a year.
Yield and peak sun hours are PVGIS estimates for Milford Haven'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 Milford Haven, assuming a south-facing roof at a 35 degree pitch with no significant shading, the same assumptions as the regional figures on this site.
