Causes and Solutions of the Potential Induced Degradation (PID) Effect
The anti-PID box reverses the potential applied by the inverter in order to polarize all of the PV modules that were affected by the negative voltage in the opposite way.

Potential Induced Degradation (PID) significantly impacts the long-term stability and reliability of photovoltaic modules. Addressing PID involves understanding its causes and
PID of photovoltaic panels is an effect that degrades the maximum power of PV modules over time. PID is a phenomenon that results in substantial solar module output and performance degradation.
PID is caused by a large electric poten-tial on the module, which in turn results in a leakage current that migrates between the cell and the other compo-nents, leading to a reduction in power.
PID is a critical issue in solar power systems, causing significant efficiency and production losses, financial impacts and reduced longevity of solar panels. Understanding the causes, impacts
If an inverter is not operational during the night, they apply an opposite bias to modules which rules out the reversible type of PID also known as polarization.
At present, the PID effect has been recognized in the industry as an important factor affecting the power of photovoltaic modules. Especially in the face of complex environments such as
The choice of glass, encapsulant used (in solar module) and the Anti-Reflective Coating (ARC) coating (on solar cell) are all found to affect and/or enhance the effect of PID.
