Experts on comprehensive photovoltaic system diagnostics and PID elimination

Our aim is to increase the efficiency of photovoltaic systems (PV). We can detect all types of faults occurring in PV modules. Your PV system is certain to produce more power with our assistance!

The owners of PV systems were able to increase their profits by almost 750 thousand EURO all due to our assistance with PID elimination.

What is PID

PID stands for Potential Induced Degradation (sometimes referred to as "high voltage stress"). It is a degradation of photovoltaic modules caused by the difference in voltage potential with respect to ground. PID causes changes in semiconductor conductivity in PV modules, which significantly reduces their capacity to generate electric power. Our measurements conducted in PV systems all across the Czech Republic reveal losses of up to 70% when comparing individual PV modules to their original output.

PV system diagnostics and PID detection

By applying a unique, tried and tested diagnostic method, we can detect PID in PV module installations. We are able to determine the amount of PID and calculate an estimate of the total power loss of the whole PV system. We have practical experience with PID detection even in large-scale installations.
