Solar Panel Servicing UK 2026
Annual solar servicing plans from £149/yr. MCS-certified engineers, all major brands, free same-week diagnostics. We service systems we didn't install — SolarEdge, Fronius, GoodWe, Enphase, SMA, Solis, Growatt, Huawei. 11,000+ installs serviced since 2012.
Why solar servicing matters
A solar PV system that's never been serviced typically produces 15-30% less electricity than its design spec by year 10. We've measured this directly on hundreds of UK homes — systems installed in 2014-2016 by companies long out of business, never inspected, never cleaned, with optimisers or inverters slowly failing without anyone noticing.
Annual servicing catches it early. For most residential systems, the saving from one corrected fault pays for 5-10 years of annual servicing. A failed SolarEdge optimiser (~£180 to replace) takes 200-400 kWh per year off your generation. A degraded panel (cleaning or warranty claim) recovers 5-15% of array output. A failing inverter (10-12 year typical lifespan) gives months of warning if anyone is looking at the data.
We're MCS certified, RECC member, NICEIC approved, and a Tesla Certified Installer. We service across the UK from our Salford depot — typical response time 5 working days for an annual service, 24 hours for emergency callouts on active plans.
