Outdoor Empirical Testing of Photovoltaic Modules

As a core member of CTC, the National Center for Quality Inspection and Testing of Solar Photovoltaic (PV) Products has systematically established a global network of outdoor performance verification sites covering multiple typical climates, based on years of experience in outdoor site construction and operation. Domestic sites include: Beijing (urban temperate environment), Haikou (high temperature, high humidity, and high ultraviolet), Mohe (extremely cold environment), Turpan (dry heat and dust), Zhangjiakou (high altitude, cold, and strong wind), and Weihai (marine climate). The overseas network includes: Base in Matera, Italy (Mediterranean climate), Arizona, USA (Desert climate), and Melbourne, Australia (Temperate maritime climate). This global system effectively expands the boundaries of laboratory testing, providing critical data to support the evaluation of the reliability, adaptability, and durability of PV products in real-world conditions.
