Serving Aberdare
Aberdare covers the CF44 postcode in the upper Cynon Valley inside Rhondda Cynon Taf County Borough Council. Population is around 39,000. The town served as a coal-mining centre through the nineteenth and twentieth centuries and has since diversified into distribution, engineering and public-sector employment.
Major employers include RCT Council and a cluster of engineering SMEs at Aberaman. Commercial estate splits between the Aberaman Industrial Estate at the south of the town and the far larger Hirwaun Industrial Estate at the top of the Heads of the Valleys. Hirwaun is particularly interesting for FLD because it sits on the upland distribution network where NGED export capacity is typically stronger than on the lower valley grid.
Landmarks include Dare Valley Country Park, which was reclaimed from heavily scarred former colliery workings, and Aberdare Park with its Grade II listed Victorian layout. The town centre retains a Victorian market hall and a walkable high street.
Infrastructure investment through 2024 to 2026 centres on the A465 dualling programme improving HGV access for Hirwaun tenants, and a planned expansion at Hirwaun Industrial Estate that will bring fresh large-footprint commercial rooftop stock online.
The grid export point matters commercially. On the upland network, commercial solar system sizing can lean more heavily toward export revenue where behind-the-meter consumption is limited, opening the door to ground-mount expansions and battery-arbitrage configurations that would not pay back on lower-valley grid connections.
At 945 kWh/kWp yield, a 200 kWp Hirwaun rooftop generates 189,000 kWh annually. Even with a more export-weighted consumption profile of 60% self-consumption and 40% export at 12p SEG, first-year benefit lands at approximately £40,000 on £170,000 capex. Simple payback 4.3 years, post-tax payback 3.1 years.
Drive time from Swansea is 55 minutes. The Heads of the Valleys corridor is a strategic focus for FLD through the 2026 commercial pipeline.

Looking after solar and electrical systems in Aberdare
A lot of our Aberdare work is not new installations at all — it is looking after equipment somebody else put in.
Where a Aberdare system exports more than it uses, commercial and domestic battery storage is what turns that export back into self-consumption, which is worth roughly double what the export tariff pays.
EV charger installation with load management is the other upgrade that pairs with an existing array in Aberdare — charging off your own generation rather than off the grid changes the arithmetic completely.
On commercial premises in Aberdare, 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 Aberdare lose output quietly — soiling on the glass, a string that has dropped out, an inverter throwing a fault code nobody reads — so planned solar maintenance and cleaning is usually the first thing worth booking on a system that is a few years old.
We are 55 minutes from Aberdare in normal traffic, which is why we can put an engineer on a fault the same week rather than the same month.
