Potential-induced degradation
Potential-induced degradation (PID) is a potential-induced performance degradation in crystalline photovoltaic modules, caused by so-called stray currents. This effect may cause power loss of up to 30 percent. The cause of the harmful leakage currents, besides the structure of the solar cell, is the voltage of the individual photovoltaic (PV) modules to the ground. In most ungrounded PV systems, the P

6 FAQs about [Photovoltaic panel offset phenomenon]
Are you experiencing a PID effect in a photovoltaic plant?
In case you are dealing with unexpected and unreasonable power loss in your photovoltaic plant, you may be experiencing the PID effect in the PV modules. Potential induced degradation (PID) is a phenomenon that arises over time (months or even years).
Does a small voltage affect a photovoltaic module's performance?
In some cases, as described in , a small voltage may have minimal impact on the module’s performance, while in other cases, a larger voltage may significantly reduce the module’s power output. There are several methods that can be used to conduct a photovoltaic potential-induced degradation (PID) test on a photovoltaic (PV) module.
Can El imaging detect photovoltaic PID in PV modules?
One of the ways in which EL imaging can be used to detect photovoltaic PID in PV modules is by looking for changes in the light emission patterns of the module [17, 18]. PID is a phenomenon that can reduce the performance of PV modules due to the presence of an electrical potential difference between the front and back electrodes of the module.
What is a photovoltaic degradation mode?
It was introduced as a degradation mode resulting from voltage potential between the cells in the photovoltaic module and ground. Research in this field was pioneered by the Jet Propulsion Laboratory, focusing primarily on electrochemical degradation in crystalline silicon and amorphous silicon photovoltaic modules.
What causes PV module degradation?
For many PV systems, PID is one of the leading causes of module degradation caused by the high voltage between the encapsulants and the front glass surface, which is grounded via the substructure of the cell or the frame 4.
How does a PID affect the output power of a solar module?
The resultant hotspots in the module will impact the yield power, therefore, and as illustrated in Fig. 3, the power loss of the modules affected after the PID is completed can vary depending on the solar illumination, but, on average, there is −25% drop in the output power.
