VDE was instrumental in the development of IEC standards for solar PV module certification. For decades the VDE Institute has been testing and certifying modules for major photovoltaic (PV) manufacturers worldwide. VDE along with our partner Fraunhofer ISE are leading the industry with the introduction of Quality Tested (QT) certification for PV power plant systems. The PV system certification is an important element in reducing risk to project developers, financial entities and insurance companies.

The technical performance and quality assurance provided by VDE Americas & Fraunhofer’s highly experienced independent assessment enable PV assets to meet long term financial goals; critical to successful project financing and YieldCo return requirements.
