Does upland location cost me significant yield vs the coast?
Merthyr sits roughly 200 m higher than Cardiff and receives around 3–5% less annual irradiance - meaningful but not decisive. Modern flat-roof stock at Pentrebach with proper tilt and array orientation still delivers strong 6–7 year payback.
Is the Welsh Government Energy Service capital funding relevant?
Very - public-sector operators (health, local authority, education) in CF47 access WGES-led capital funding at rates commercial asset finance cannot match. Payback on public-estate PV frequently collapses to under 5 years as a result.
What about upland weather and array durability?
Higher wind loading and increased snow events at 200m+ alter fixing spec and tilt calculations, not viability. We design to MCS 012 with Cumbria / Peak-District-equivalent loading assumptions where relevant.
How is DNO capacity at CF47 / CF48?
National Grid Electricity Distribution covers the area. Valleys headroom has historically been more constrained than the coast, but Heads of the Valleys reinforcement has helped. Default export limitation on G99 keeps queue times reasonable for sub-500 kWp.
How wide is Valleys coverage from Merthyr?
Aberfan, Troedyrhiw, Dowlais, Cefn Coed, Trelewis, Bedlinog and along the A465 to Ebbw Vale and Neath are all routine. The Wales team handles surveying, install and monitoring across upland valleys postcodes.
