PID EFEKT, DIAGNOSTIKA A DŮSLEDKY

Popis výsledku v původním jazyce

PID stands for "Potential Induced Degradation", a phenomenon first described in the 1970s. Furthermore, the PID was forgotten and module manufacturers, together with photovoltaic power plant owners, started to deal with it again in the new millennium, when it started to show up strongly in larger power plants. The impact of the PID on the power plant can be very significant, due to the fact that modules can lose up to 70 % of their original performance in real conditions due to PID. In addition, some modules run faster and the power plant becomes financially loss-making. The reach of the PID module increases over time and can cause high energy losses and ultimately total module failure. There are several types of PID. Some are reversible, others are not, and for some, the principle of their origin is relatively well known, while in others it is only speculated. However, they have one thing in common, namely that the basic condition for creating a PID is a high voltage difference in the string, so it is also sometimes called High-Voltage stress. PV systems using crystalline silicon are mostly PID shunting (PID-s), where local short-circuits are generated and thus a significant reduction in performance. Thin-film modules may also suffer from a PID effect. As a rule, thin-film modules are not reversible degradation due to electrochemical corrosion of the TCO layer (transparent conductive oxide).
