Potential-induced degradation (PID) of PV modules containing silicon solar cells is an issue with high relevance to the long-term reliability of PV systems [1]. Despite knowledge of methods for ...
pv magazine: Mr Viaro, is it possible to produce a completely PID free pv module? And what would be needed for that? Andrea Viaro: “PID-free” is a misconception, because the phenomenon is influenced ...
Scientists in Germany have developed a “heavy duty” test to provide insight into the long term effects of potential induced degradation in PV modules. The tests go well beyond those established by IEC ...
The encapsulant producers tell us that more than 50% of what they sell is not PID-free just because that version is a bit more expensive. In some cases the manufacturers will claim their modules are ...
