A Welsh electrical & solar contractor built for farms.
RLW Electrical & Solar designs, installs and maintains commercial solar PV, battery storage and electrical systems for farms and rural businesses across Wales. We bring electrical engineering and commercial solar expertise to every project — from the first survey to long-term aftercare.
Why we focus on farms
Farms have the three things solar needs most: large roofs, open land and significant daytime demand. A dairy parlour, a grain store, a workshop — they draw power exactly when generation is at its peak.
That makes farms some of the best commercial solar sites in Wales. But it has to be engineered correctly: sized to the meter, sited for output, and installed around the farm's working day. We design and install to the farm's requirements, not the other way around.
From a single barn array to a diversified estate with batteries and EV charging, we design, install and look after the lot — so you deal with one accredited local team, not a string of subcontractors.
Engineered to perform
Every system is modelled against your actual usage and sited for orientation, shading and export — so the predicted generation and savings hold up in the real world.
Done properly
MCS-certified installation, fully insured crews and a real workmanship guarantee. No shortcuts on the roof or the wiring.
Monitored & supported
24/7 remote monitoring flags performance issues as they arise, supporting ongoing system management and protecting long-term value.
Working across Wales
From Carmarthenshire to Powys, Pembrokeshire to the borders — wherever there's a farm that wants to cut its electricity costs, we'll come and take a look.
