In my last post, I mentioned the PID effect, which significantly decreases photovoltaic arrays’ performance. Now, I want to show how PID can be diagnosed using a few different analysis methods. As discussed in my last post on this topic, outdoor electroluminescence analysis is the best way to detect the PID effect. This method lets […]
Read articlePotential-induced degradation (PID) of photovoltaic panels
Potential induced degradation affects many solar power arrays by reducing panel performance more and more over time. Although some types of PID are reversible, others are not, and those are therefore a permanent problem for the affected modules. This article describes the causes of PID, how to detect it, and how to prevent it. All […]
