Watch as DuPont and Yingli Solar install a 210 kilowatt solar power project on the rooftop of the DuPont China R&D Center in Shanghai. Yingli’s unique, n-type PANDA solar cells, which are made using new DuPont™ Solamet® PV3Nx silver and aluminum metallization pastes, help maximize power output for the project. To help ensure long-term durability, DuPont™ Tedlar® film-based backsheets in a double layer construction were specified, and lightweight framing materials from DuPont were utilized to decrease the weight on the roof and ease installation. This is the 14th solar installation at a DuPont site to date. More than 11 million kilowatt hours of solar energy are produced at DuPont facilities annually.
