About Caerphilly
Caerphilly is dominated by its astonishing thirteenth-century castle, the largest in Wales and one of the largest in Britain. Built between 1268 and 1271 by Gilbert de Clare, the Red Earl of Hertford, the castle's concentric defences, elaborate water defences, and leaning south-eastern tower make it one of the masterpieces of medieval military architecture in Europe. The castle's scale was a deliberate statement of Marcher lord power against the encroaching ambitions of the native Welsh princes.
The town that grew around the castle was always overshadowed by Cardiff, ten miles to the south, but Caerphilly developed its own distinctive character in the nineteenth century as a centre of coal mining and as the marketplace for the surrounding valleys. The town is also famous for the cheese that bears its name — a mild, crumbly white cheese that was originally made by farmers in the surrounding hill country as a portable food for miners, and which has experienced a strong revival in recent decades through specialist Welsh producers.
Modern Caerphilly has around 41,000 residents in the town and 175,000 in the wider county borough, which stretches from the outskirts of Cardiff up into the Rhymney Valley. The town is a major commuter centre for Cardiff and Newport, with excellent rail and road connections, and benefits from the proximity of the Forest of Eppynt, the Brecon Beacons National Park, and the south Wales valleys for residents who value rural surroundings within easy reach of urban work.
Why solar makes sense in Caerphilly
Caerphilly sits in the south Wales solar irradiation belt and shares the same generation potential as Cardiff and Newport. The slightly higher elevation of parts of the town does not meaningfully affect solar performance, and the relatively low pollution levels compared to coastal industrial areas favour panel longevity.
The housing stock is varied: terraced houses in the central wards and along the railway, interwar housing on the slopes above the castle, post-war estate housing in St Martins and Lansbury Park, and substantial new development at Penyrheol, Trecenydd, and along the eastern fringe. The wider county borough includes the post-industrial valleys towns of Bargoed, Risca, and Ystrad Mynach, which we also cover routinely.
We work across the whole Caerphilly county borough from Senghenydd in the upper valleys to Risca near Newport. The local DNO is National Grid Electricity Distribution.

What our Caerphilly customers say
Genuine reviews from recent installations across Caerphilly and the surrounding area.
"Welsh Solar fitted a 4 kW system on our home with no fuss. The team were polite, professional, and tidy. Two years on, the system is performing exactly as the quote said it would."
— Jeffrey M., Caerphilly
"Brilliant service. Clear quote, fixed price, and an installation that went exactly to plan. The savings on our bills have been substantial."
— Helen P., Penyrheol
"Living up in the valleys we wondered if it would be worthwhile. Welsh Solar were honest about the slightly lower yield and the system has delivered above their conservative forecast."
— Rhys W., Bargoed
"Good work and a fair price. Communication could have been slightly tighter during the DNO wait, but Welsh Solar got us connected as soon as approval came through."
— Eluned T., Trecenydd
Frequently asked questions about solar in Caerphilly
Is Caerphilly a good location for solar?
Yes, Caerphilly enjoys the same solar irradiation as Cardiff. Typical 4 kW systems produce around 3,400-3,500 kWh per year, which covers 40-60% of a typical household's annual electricity demand.
Do you cover the upper valleys?
Yes, our service area covers the whole of Caerphilly county borough, including Bargoed, Aberbargoed, Senghenydd, and the upper Rhymney valley. The slightly higher elevation makes no meaningful difference to solar performance.
Are the houses in the valleys suitable?
Most traditional valleys terraces have rear elevations that face suitable directions, and modern estate housing in places like Penyrheol and Trecenydd offers excellent conditions. We have completed many installations across the valleys.
What about planning around Caerphilly Castle?
The area immediately around the castle has heritage considerations, but standard residential installations elsewhere in the town fall within permitted development. We handle any planning applications as part of our service.
How does proximity to Cardiff affect installation?
It doesn't affect technical aspects, but practically Caerphilly is easy for our south Wales-based teams to reach, which keeps mobilisation costs down and timescales tight.
