FAQ
Surface scratches and cracks
Reasons: The surface of the solar panel may be scratched or cracked for various reasons (such as external impact, improper installation, etc.).
Impact: These damages will reduce the efficiency of light absorption, thus affecting the power generation effect.
Treatment method: Regular cleaning and inspection, repair in time after finding damage, such as using transparent tape to cover small cracks.
Snail tracks or worm tracks
The phenomenon: The short, thin dark lines that appear on the surface of solar panels are unrelated to real snails and are the product of oxidation.
Cause: Usually caused by microscopic cracks in the panel or defective front metallized silver paste during manufacturing.
Impact: Although it mainly affects the appearance of the module, it has no significant impact on efficiency.
Potential induced degradation (PID)
Cause: Stray current caused by the mismatch between the voltage of the module and the ground.
Impact: Can reduce the power output of photovoltaic devices by one-third.
Prevention: Using a micro inverter can reduce the occurrence of PID, because the micro inverter does not allow the voltage to be too high.
