Solar systems are low maintenance – but not maintenance free. Contamination of the PV modules, water levels in the lead batteries, deep discharge, technical defects… require specialised personnel for maintenance and service.

Road dust is a major problem at many sites near unpaved roads. The PV modules quickly disappear under a thick layer of dust and performance drops. Pigeons can also be a problem and require frequent cleaning.

We show you how to clean PV modules without damaging them:
Clean water is essential. We go on a quest with the water quality analysis material. Then you need the right equipment: carbon rods with water-flowing brushes, water tank, pressure pump… You have to learn how to use it. At Radford, depending on the season, performance drops by 20% after just 14 days. Frequent cleaning is therefore advisable.
