Event at Intersolar NA
International PV Module Quality Assurance Forum Environment-Specific Module Durability Testing
The International PV Module Quality Assurance Forum seeks international participation to define a concept for creation of standards that allow stakeholders to quickly assess a module's ability to withstand regional stresses. Such standards would reduce risk and add confidence for those developing products, designing incentive programs, and determining private investments.
