New PID tests presented by ZSW
The German centre ZSW this week presented new test protocols designed to give PV investors and project developers certainty about the resistance of solar panels to potential-induced degradation (PID).
The tests were designed to
to go far beyond those stipulated by the International Electrotechnical Commission in its standard regime IEC TS 62804-1. This requires only that the panels undergo wet heat testing at 85 degrees Celsius, and at 85% humidity for 96 hours at the nominal module voltage - 1,500 V in most cases. They must retain at least 95% of their initial performance after the test.
