Solar Panel Degradation Prevention Technology

Extract the highest yield from solar power at the lowest cost!


In commercial PV plants even the smallest string mismatch effects efficiency, reducing 2-15% (and more) of the overall energy yield.
String mismatches are practically unavoidable as there are always variations in shading and soiling and more between strings.

Vigdu String Level Optimizer Cost effective, Plug & Play Installation only on mismatched strings solves this problem.

Prevent Solar Panel Degradation!

Why anti-PID devices are an essential part of Solar PV System?

As solar power becomes more used worldwide, it becomes clear that the primary problem of Solar PV technology and the effective solar system is a power loss due to the unavoidable PID effect.
PID effect in the solar system is caused by numerous factors.

Anti PID device is a necessary (essential) component of any commercial Solar system or plant that consists of solar PV panels and inverters.
Installation of a professional anti PID solution ensures maximum efficiency and the highest yield of solar power as well as longer system use with reduced maintenance or need of panel replacement.
