About Carmarthen
Carmarthen — Caerfyrddin in Welsh — claims to be the oldest town in Wales, with origins as the Roman fort of Moridunum, established around AD 75 on a site that was already an important crossing of the River Tywi. The Roman amphitheatre on the eastern edge of the town remains one of the best-preserved in Britain, and the modern town has grown around the medieval castle built by William fitz Baldwin in 1094 to consolidate Norman control of west Wales.
Carmarthen has long been the administrative and market centre of Carmarthenshire, the largest county in Wales by area, and the surrounding agricultural land has shaped its character for centuries. The town was important enough in medieval Wales to host the Eisteddfod of 1451, where the formal rules of Welsh strict-metre poetry — the cynghanedd — were codified by Dafydd ab Edmwnd. The Carmarthen-born Bishop Richard Davies and the poet William Williams Pantycelyn, who wrote some of the most enduring Welsh hymns, are among the figures most associated with the town.
Modern Carmarthen has around 14,000 residents and remains a strong market and administrative town. The county hospital, the Coleg Sir Gar campus, and the offices of Carmarthenshire County Council make it a significant employment centre for the wider area. Carmarthen is also a stronghold of the Welsh language, with Welsh-medium education thriving and a substantial proportion of residents being fluent speakers.
Why solar makes sense in Carmarthen
West Wales receives good solar irradiation thanks to long summer daylight hours and relatively low pollution levels compared to industrial parts of the country. Annual generation in Carmarthen is comparable to most of southern Wales, and the slightly higher rainfall favours self-cleaning of panels.
Carmarthen's housing stock includes Georgian and Victorian properties in the centre, Edwardian and interwar housing across the suburbs, modern estate development at Pibwrlwyd, Travellers Rest, and Johnstown, and a substantial number of rural farms and smallholdings across the surrounding countryside. The agricultural character of the area makes farm-based solar plus battery systems particularly common in our local installations.
We cover Carmarthen, Johnstown, Travellers Rest, Llangunnor, Bancyfelin, Whitland, Llandeilo, and routinely work across the whole of Carmarthenshire from this base. The local DNO is National Grid Electricity Distribution.

Frequently asked questions about solar in Carmarthen
Is rural Carmarthenshire a good area for solar?
Yes, rural west Wales is excellent for solar — clear skies on summer days, low atmospheric pollution, and many properties with generous south-facing roofs unobstructed by neighbouring buildings.
Do you install on farms across the county?
We routinely install on farms across Carmarthenshire — dairy, beef, sheep, and arable. Farm installations often pair solar with battery storage to power refrigeration, milking equipment, and other daytime loads.
How do I handle a listed farmhouse?
Listed buildings need listed building consent in addition to or instead of planning permission. We have experience with applications across Carmarthenshire and our local team works closely with the council's conservation officers.
What about properties on three-phase supplies?
Many rural Carmarthenshire properties have three-phase electrical supplies, which is actually beneficial for solar — it allows balanced generation across all phases and supports larger systems. We have extensive experience with three-phase installations.
Do you cover Llandeilo, Llanelli, and Whitland?
Yes, our team covers the whole of Carmarthenshire as standard. Llanelli has its own dedicated location page, but Llandeilo, Whitland, Kidwelly, Ammanford, and the rural villages between are all within our routine service area.
