The adoption of non-metallic frame encapsulation for PV modules greatly reduces the possibility of forming leakage loops, which helps to reduce the generation of PID potential-induced decay phenomenon. the harm of PID effect makes the power of the cell module decay and reduces power generation.

PID

However, this solution is not possible with ‘floating’ PV systems and halves the possible voltage range for grounded systems, thus increasing the balance of system costs. The amount of PID in PV modules can be strongly reduced by applying encapsulants with higher electrical resistance thus reducing the polarization effects [5,7].
