Encapsulated using 2.5 mm thick tempered glass on both sides with frameless design, 60-cell multi-Si Modules are weatherproof for deployment in extreme environments with high temperature/humidity, wind, salt, and arid conditions. Modules are based on IEC standard for 1,500 V system with no greater than 2.5% power degradation in first year followed by linear annual degradation rate of 0.5%. In addition to passing IEC61215 and IEC61730 reliability tests, modules obtained TUV SUD certifications.
