The Trina Solar Duomax Twin TSM-DEG18C.20 is a 520-555W P-type PERC bifacial dual glass monocrystalline module. Built with 210mm large wafers, half-cut cells and multi-busbar design, it combines high density interconnect technology with non-destructive cutting for better light trapping, lower series resistance and improved current collection. The bifacial dual glass construction captures scattered light from the rear side for extra power output.
Product overview
Original A-grade TrinaSolar Duomax Twin photovoltaic modules. The dual glass laminate minimises micro-cracks and ensures PID resistance through cell process and module material control. Mechanical performance reaches 5400Pa positive load and 2400Pa negative load, with certified resistance to salt, ammonia, sand, high temperature and high humidity.
