Serving Clydach
Clydach, at the head of the Swansea Valley, carries a population of approximately 7,500 and is dominated economically by a single employer. The Vale Clydach Refinery, also known as The Mond, is the largest nickel refinery in Europe. Founded in 1902 and operating as a top-tier COMAH site, it employs around 240 people producing 99.9% pure nickel powder and pellets that feed directly into the stainless-steel and EV battery supply chains.
The importance of Clydach nickel has grown sharply with the UK EV battery investment cycle. Gigafactory projects at Sunderland, Somerset and Coventry rely on supply chains that include Clydach product, and the result is explicit Scope 3 reporting pressure on The Mond from its downstream OEM customers. That in turn drives a commercial solar business case on-site that would have been unthinkable a decade ago.
Surrounding the refinery, the Swansea Vale trading estate hosts a concentration of SMEs, and the town centre runs a traditional high street along the A4067. Housing is a mix of terraced Victorian ex-industrial cottages and interwar semi-detached properties climbing the valley sides. Landmarks include the Swansea Canal, one of the earliest industrial canals in Wales at 1794 to 1798, the Mond Memorial in the town itself, and the Lliw Valley reservoirs a few miles north.
At a PVGIS yield of 950 kWh/kWp, Clydach is the same baseline as the rest of the Swansea Valley. The scale opportunity sits with The Mond and its supply-chain tenants. A 1 MW rooftop array on a refinery-adjacent logistics shed generates 950,000 kWh per year. At 25p/kWh blended self-consumption (Clydach has very high continuous process load) that is £237,500 of first-year benefit.
For domestic work in Clydach, the valley-sided housing stock and frequent proximity of mature trees means that SolarEdge panel-level optimisation recovers significant yield over a standard string inverter. We specify SolarEdge by default for this postcode precisely because shade losses would otherwise compromise generation.
The town sits 15 minutes from our Swansea base. We know the Mond gate procedures, we hold ConstructionLine for supply-chain framework tendering, and we have the industrial electrical scope to match.

Looking after solar and electrical systems in Clydach
Once a system is on the roof in Clydach, the question changes from "what will it cost" to "who looks after it".
On commercial premises in Clydach, an LED lighting replacement normally pays back faster than anything else on the building, and it cuts the load the solar has to cover in the first place.
Existing arrays around Clydach lose output quietly — soiling on the glass, a string that has dropped out, an inverter throwing a fault code nobody reads — so solar maintenance, cleaning and thermographic surveys is usually the first thing worth booking on a system that is a few years old.
Where a Clydach system exports more than it uses, adding battery storage is what turns that export back into self-consumption, which is worth roughly double what the export tariff pays.
workplace and home EV charging is the other upgrade that pairs with an existing array in Clydach — charging off your own generation rather than off the grid changes the arithmetic completely.
We are 15 minutes from Clydach in normal traffic, which is why we can put an engineer on a fault the same week rather than the same month.
