8.2
Module appearance inspection
Check module appearance defects visually, especially:
1. Module glass cracks.
2. Corrosion at welding parts of the cell main grid: it is caused by moisture into the module due
to damage of surface packaging materials during installation or transportation.
3. Check whether there is burning traces on the module back plate.
8.3
Inspection of connectors and cables
It is suggested to carry out a preventive inspection once every 6 month:
1. Check connector sealing and cable connection solidness.
2. Check whether sealant of the terminal box is cracking with gap.
