Serving Ammanford
Ammanford occupies the SA18 postcode on the Carmarthenshire side of the Black Mountain, with a town population near 5,500 and wider ward population near 11,000. The surrounding Cross Hands corridor is the distribution and manufacturing centre of gravity for mid-Carmarthenshire.
Key employers include Coleg Sir Gar's Ammanford campus, a cluster of engineering SMEs, and the distribution operators based along the Cross Hands axis. Cross Hands Business Park is home to Castell Howell Foods, which is widely cited as a South Wales reference case for commercial solar thanks to its approximately 845 kWp rooftop PV installation. Rhyd-y-Fro Industrial Estate provides additional secondary commercial estate.
Landmarks include Carreg Cennen Castle, a Grade I listed medieval fortress set dramatically on a limestone outcrop south-east of the town, and the Black Mountain itself which defines the horizon to the north.
Cross Hands West Phase 2 is bringing fresh industrial floorspace through 2024 to 2026, with further distribution demand from regional logistics operators. That creates a concentrated pipeline of new commercial rooftops at the scale (typically 5,000 to 15,000 m2 single-building) where commercial solar economics are strongest.
The competitive context here is important. The Ammanford and Cross Hands catchment sits directly inside the territory where Mypower's well-known South Wales commercial solar case study (Castell Howell Foods) was developed. A Swansea-based specialist with faster same-day site visits and direct NGED pre-application engagement is well-positioned to contest that market.
At 955 kWh/kWp PVGIS yield, a 500 kWp rooftop at a Cross Hands distribution tenant generates 477,500 kWh per year. With 75% self-consumption at 27p/kWh blended, first-year benefit sits at approximately £106,000. Simple payback is 3.8 years on £400,000 capex, post-tax payback 2.8 years under Annual Investment Allowance.
We are 25 minutes from Ammanford via the A483, and the route is consistent enough to support same-day survey commitments.

Looking after solar and electrical systems in Ammanford
The jobs that keep bringing us back to Ammanford tend to be maintenance and upgrades rather than first fits.
EV charger installation is the other upgrade that pairs with an existing array in Ammanford — charging off your own generation rather than off the grid changes the arithmetic completely.
On commercial premises in Ammanford, commercial LED lighting upgrades 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 Ammanford lose output quietly — soiling on the glass, a string that has dropped out, an inverter throwing a fault code nobody reads — so solar panel cleaning and O&M is usually the first thing worth booking on a system that is a few years old.
Where a Ammanford system exports more than it uses, battery storage sized to the actual load is what turns that export back into self-consumption, which is worth roughly double what the export tariff pays.
We are 25 minutes from Ammanford in normal traffic, which is why we can put an engineer on a fault the same week rather than the same month.
