In Canada and the US, Yingli Solar modules have been certified by Underwriters Laboratories Inc (UL) which is North America’s leading independent product safety certification organisation. Similarly the Clean Energy Council (CEC), the key certification organisation for Australia’s clean energy sector, has certified Yingli Solar modules. In Brazil, Yingli Solar modules have scored top marks in testing conducted by National Institute of Metrology, Quality and Technology (Inmetro) certification for PV systems, a prerequisite for solar products to be sold in Brazil. Yingli Solar has also secured certification from Japan Electrical Safety & Environment Technology Laboratories (JET), the leading independent certification organisation for solar energy products in Japan. Product certifications, acquired through rigorous testing in different markets, helps reassure our partners and clients that our products are in line with the industry product and safety standards. Solar certifications show customers in various markets served by Yingli Solar that our solar modules are fit for purpose for their 25+ years of service. For instance, the IEC certification requires high standards of solar equip­ment for example in relation to extremes of cli­mate as well as mechanical load, all of which are core drivers for the ageing of PV modules. Internationally-recognised certification is also of course required by law in different geographic areas. While not compulsory, certifications from independent bodies like UL (in North America) are essential to get solar systems connected to the local electricity grid and are required in many markets to secure government subsidies. Certification by a recognised and respected third party is also essential for insurance purposes. Additionally, the credibility offered by independent certification of the r­ eliability and durability of PV modules promotes the wider global use of solar power, a vital source of clean energy. © TÜV Rheinland Promoting Confidence in Our CustomerS Certification validates the high standards which Yingli Solar sets in the production of its products.
