Solar Thermal System Testing

Testing of solar thermal systems and collectors

Tapping the Sun’s Power to Generate Heat

Solar Thermal Systems - TÜV Rheinland

Along with their capacity, the reliability and service life of solar panels are key factors when considering installation of a solar power plant. National and international companies rely on TÜV Rheinland’s solar thermal test laboratory and its testing and certification services to ensure the quality, safety, reliability, and performance of their solar thermal products. Our laboratory’s services comply with the DIN/EN/ISOIEC 17025 norm. In addition, ours is an accredited test laboratory for DIN CERTCO for Solar Keymark and by the Solar Rating and Certification Corporation (SRCC).
