It is known that the problems and failures that monocrystalline and polycrystalline PV modules often exhibit are due to various factors, both on the manufacturing side and operation/use side.
The 11 most common manufacturing defects of crystalline PV modules are:
- LID
- Premature aging
- PID
- Diode failure
- Soldering failure
- Cell microcracks
- Snail trails
- Burnt spots on frontsheet or backsheet
- Frontsheet or backsheet delamination
- Cell corrosion
- Cell wiring failure
In order to claim the repair of the PV modules defect from the manufacturing companies, it is necessary to diagnose these problems using specific certified methods.
