Porthcawl’s domestic solar market benefits from one of the highest yield baselines in the FLD coverage area. The CF36 PVGIS baseline of 960 kWh/kWp reflects the peninsula position at the south-western tip of the Vale of Glamorgan, where Atlantic coastal exposure and the absence of inland valley shading combine to produce reliable high-output conditions.
Rest Bay and Newton: premium residential stock
Rest Bay and Newton carry detached bungalows and large semi-detached on open coastal plots with unobstructed southern horizon views over Swansea Bay and minimal inter-row shading. Bungalows at Rest Bay typically carry significant south-facing roof area — 5.5 kWp to 7 kWp arrays are often viable.
At 962 kWh/kWp, a 6 kWp south-facing bungalow installation generates 5,772 kWh annually. For a retired couple with high daytime occupancy at 55% self-consumption, year-one benefit: approximately £1,150. On £9,800 installed cost, payback: 8.5 years. Adding a 10 kWh battery raises year-one benefit to approximately £1,380 and combined payback on £17,200 to 12.5 years.
Atlantic coastal specification
Properties within 500 metres of the coastline at Rest Bay receive marine-grade stainless steel mounting fixings, IP66 or higher inverter enclosures, and marine-specification cable connectors. FLD includes this specification in all coastal CF36 quotations without surcharge.
Conservation area: Porthcawl town seafront
The Porthcawl town centre seafront is within the conservation area covered in FLD’s first Porthcawl guide in the context of hospitality solar. The same in-roof integrated specification applies to residential properties in the CF36 conservation zone. FLD recommends pre-application consultation with Bridgend County Borough Council’s planning department before proceeding to survey.
Holiday let economics
A Porthcawl holiday let with 36-week summer occupancy achieves self-consumption rates of 65% to 75% during the letting season — significantly better than a year-round low-occupancy permanent residence. Combined with 0% VAT on residential solar, holiday let owners in CF36 have one of the most compelling domestic solar investment cases in Wales.
