Snail pattern
The snail pattern, lightning pattern, and worm pattern cause the power generation capacity of the power station to decay rapidly, and the power station can be scrapped in 5 years. In August 2013, a 50MW photovoltaic power station in Bohu, a central state-owned enterprise in Xinjiang, appeared in batches of snail patterns, with a module occurrence rate of 75%. In 2014, 30% of 250MW photovoltaic power station modules in Shandong showed snail patterns. In 2014, Zhejiang Hangzhou East Railway Station 10MW photovoltaic power station 1500 Snail patterns appear on the block components and so on.
 
Hot spots
Hot spots cause damage to the entire battery assembly and cause losses.
 
Backplane yellowing
The yellowing of the backplane reduces the reflection of sunlight, which in turn affects the solar cell's absorption effect of sunlight, and ultimately reduces the power output of the module.
 
Broken glass
The glass is broken, the cell and the connecting wire begin to oxidize and corrode, and the life is shortened
