Solar Panel Servicing & Maintenance in South Wales
Solar panel servicing, maintenance and repairs across South Wales — Cardiff and the Vale, Swansea Bay and Gower, Newport and the Gwent levels. Estuary and Atlantic salt, the wettest weather in Britain and a huge stock of feed-in-tariff systems now 10-plus years old all quietly steal generation. Our South Wales engineers find and fix what your installer never came back to check.
Why South Wales solar systems need specialist care
South Wales works solar systems hard: salt off the Severn Estuary and Swansea Bay, rainfall that tops the UK tables, and one of the country's densest concentrations of 2010–2015 feed-in-tariff installs now reaching the age where inverters fail.
Two coasts of salt
From the Severn Estuary at Newport and Cardiff Bay round to the open Atlantic at Swansea and Gower, salt-laden air corrodes frames, fixings and inverters years earlier than inland roofs.
The wettest cities in Britain
Swansea and Cardiff regularly top the UK rainfall tables. Persistent damp drives moss and lichen across slate terrace roofs, shading cells and holding moisture against the fixings.
FIT-era systems coming of age
South Wales installed solar heavily between 2010 and 2015 on the feed-in tariff. Those systems are now squarely in the inverter-failure window — and every lost kilowatt-hour costs FIT income as well as bill savings.

South Wales solar maintenance FAQs
Where in South Wales do you cover?
We cover Cardiff and the Vale of Glamorgan, Swansea, Gower and Neath Port Talbot, and Newport with the surrounding Gwent towns — Cwmbran, Caerphilly, Pontypool, Caldicot and Chepstow. Our South Wales engineer team books most visits within the same week.
Why do South Wales solar systems need maintenance?
Salt from the Severn Estuary and Swansea Bay corrodes hardware, exceptional rainfall drives moss and lichen, and the region's feed-in-tariff boom means thousands of systems are now 10 to 15 years old — the age when inverters fail and generation quietly slides. Unchecked systems typically lose 15 to 25 percent of output within seven years.
How much does solar maintenance cost in South Wales?
Every system starts with a fixed-price 21-point Solar MOT. Ongoing care plans run from £16.99 per month (Care), £29.99 (Care Plus) to £44.99 (Care Pro), with no call-out charges across South Wales.
Do you repair as well as service solar panels?
Yes. Inverter faults and replacements, panel and cabling repairs, moss and salt cleaning, bird proofing and performance recovery across all major brands, whoever installed your system.
