Serving Tywyn
Tywyn is a small coastal town on the southern Meirionnydd coast in Gwynedd, population approximately 3,200, sitting on the flat coastal plain between the Cardigan Bay beach and the Dysynni valley. At 970 kWh/kWp yield, Tywyn matches Harlech as the highest-generating location in FLD's Gwynedd coverage, benefiting from unobstructed south-west Atlantic exposure across Cardigan Bay.
Unlike Harlech and Barmouth, Tywyn is not entirely within the Eryri National Park. The Park boundary runs approximately a mile inland from the town, and the coastal strip where Tywyn itself sits is outside the Park boundary. This distinction has a significant practical consequence for solar permitting: standard Welsh permitted development rules apply to Tywyn town properties without the additional ENPA pre-application layer that applies at Harlech and Barmouth.
The Talyllyn Railway terminus is Tywyn Wharf station -- the Talyllyn was the world's first preserved railway, restored by volunteers in 1951 after the death of its last private owner. The railway runs 7.25 miles inland to Nant Gwernol and is a major Gwynedd heritage tourism attraction. The railway estate carries multiple buildings at Tywyn Wharf and at intermediate stations that could represent a heritage-sector commercial solar opportunity assessed through the Talyllyn's own estate management.
The wider economy combines coastal tourism (a long sandy beach, surf school, water sports), the Talyllyn Railway visitor operation, and service provision for the surrounding agricultural community. Several caravan and holiday parks north and south of the town on the Cardigan Bay shore add to the hospitality commercial base.
Tywyn's housing mix is more varied than the hillside resort towns of Barmouth and Harlech. The town centre carries Victorian terraces and inter-war semis. The newer residential estate development to the east provides modern cavity-wall stock with standard roof orientations. The coastal fringe has larger detacheds and bungalows, many used as holiday accommodation.
At 970 kWh/kWp, a 6 kWp domestic system on a south-facing Tywyn semi-detached generates 5,820 kWh annually. With battery storage and time-of-use tariff, annual saving reaches approximately £1,650. For a holiday caravan park on the coastal fringe, a 100 kWp installation on shower blocks and amenity buildings generates 97,000 kWh annually -- self-consumption above 80% in the June to August peak, with a payback of approximately 3.5 years.
FLD reaches Tywyn in approximately 120 minutes via the A487 and A493. Coverage combines with Machynlleth and Barmouth on a southern Cambrian Coast circuit.
