During CGC's rigorous testing process, DMEGC Solar's modules successfully endured accelerated aging tests simulating harsh environments such as deserts and high-altitude regions, withstanding cumulative UV irradiation of 300 kWh/m²—equivalent to 25 years of outdoor exposure. The modules demonstrated a performance degradation rate of less than 2%, far exceeding the required benchmark.
A CGC technical expert explained that this certification standard introduces, for the first time, a three-tier UV resistance classification system (UV100/200/300). DMEGC Solar is among the first manufacturers in the industry to achieve the highest UV300 rating, which is crucial for ensuring long-term returns on PV power plants in high-irradiation regions.
As global PV installations increasingly shift toward high-sunlight regions, UV resistance has become a key performance indicator for investors. This certification will serve as a critical technical endorsement for DMEGC Solar's expansion into emerging markets such as the Middle East, North Africa, Australia, and Latin America. Third-party estimates suggest that using UV300-grade modules can reduce operational and maintenance losses by approximately 7% over a 30-year lifespan, increasing overall investment returns by more than 1.5 percentage points.
CGC (China General Certification Center) is a leading third-party certification body in China, specializing in testing, inspection, and certification services for renewable energy, industrial equipment, and consumer products. Established in 2003, CGC is accredited by the China National Accreditation Service for Conformity Assessment (CNAS) and recognized by international organizations, ensuring its certifications meet both domestic and global standards.
