The tests performed by PI Berlin prove the effectiveness and widely appreciated characteristics of the high class PID solution by Pidbull to reliably cure and prevent PID in PV modules. The Photovoltaik-Institut Berlin is an international PV research institute with proven independence. Testing was done by PI Berlin from May 5th 2017 until July 2nd 2018, Pidbull announces.
According to Pidbull the gadgets have a proven track record with PR increases from six percent to 23 percent and preventing further losses both for PV plants with central and string inverters. Conservative loss due to PID after seven years of PV-operation is at least 5 percent of annual revenue.
In case of string inverters the investment to solve PID amounts to just 4,5 percent of annual revenue whereas in case of PV-plants with central inverters the investment can be as little as one percent of annual revenue. (nhp)
