ZSW Develops Method of Lifetime Testing for PID

The Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) has developed a heavy-duty test that provides more accurate information about a solar module’s resistance to potential-induced degradation (PID). The phenomenon known as PID occurs when leakage currents caused by a difference in voltages between solar cells and the grounded frame adversely affect a photovoltaic […]
