How much does solar panel maintenance cost?
1 min read · Updated 15 October 2026
The short answer
A standalone inspection usually costs from around £100 to £200. Cleaning, repairs and parts are on top.
Inspection
A visual and electrical check of the array, inverter, isolators and connections.
Cleaning
In most of the UK, rain does enough. Cleaning is only worth paying for if panels are shaded by trees or near the coast or a farm.
Repairs
Inverter replacement is the big one, so it's worth knowing what yours would cost before it happens.
