5.4 Visual inspection of the module
During regular cleaning cycles, be sure to visually inspect each module. The purpose of visual
inspection is to detect possible faults or damage. Specifically:
Possible broken glass.
Rust on the circuits and soldering of the PV cells. Normally this is due to moisture
entering the module through a breakage in the encapsulating layer during installation or
transport.
5.5 Inspecting connections and cabling
While performing preventive maintenance every 6 months, carrying out the following
operations:
Check the tightness and condition of the connection cable junctions.
Check the junction box sealing. Should sealing faults be observed, the items which have
been affected should be replaced and cleaned. Contact BenQ Solar for additional
information about resolving faults in module seal.
