How cold solder joints turn solar modules into warranty cases

In the run-up to pv magazine’s quality roundtable at Intersolar Europe, we look at a case where a production error resulted in cold solder joints in 5% of the solar modules across a 50 MW project portfolio. We consider how to come to an agreement with a manufacturer to replace modules in such a situation and how such a solution compares with a production audit before installation.
