What solar actually does in Ystalyfera
Keiron holds the OVO Solar & Battery partnership for South Wales, and Ystalyfera 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 Ystalyfera at 900 kWh per kWp a year, so a 14 panel (6.3 kWp) system here generates around 5,670 kWh a year.
Yield and peak sun hours are PVGIS estimates for Ystalyfera'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 Ystalyfera, assuming a south-facing roof at a 35 degree pitch with no significant shading, the same assumptions as the regional figures on this site.
