Photovoltaik Institut Berlin AG (PI Berlin), based in Berlin, has received accreditation as an official ISO/IEC testing laboratory for the photovoltaics industry. Widely recognized in Europe for its reliability testing and engineering analysis, the independent firm is expanding to meet the growing demand of the US market and has confirmed US module manufacturer Solaria Corp. as its first customer in North America. The move to become an accredited ISO/IEC lab evolved as a result of the mounting demand for quality engineering.
