New goods bifacial 320w 450w trina solar panel bifacial dual glass for solar panel system

These Trina Solar bifacial panels feature advanced dual-glass construction with transparent backsheet technology, offering superior durability and light transmission. The 320W and 450W models utilize 120 half-cut monocrystalline PERC cells with multi-busbar design, achieving up to 21.2% front-side efficiency. The 2.5mm front glass/2.0mm rear glass construction provides exceptional resistance to environmental stress while allowing 90% rear-side light transmission. The frameless design eliminates potential corrosion and reduces dust accumulation. These panels demonstrate bifacial gains of 5-25% depending on installation height and surface albedo. The half-cell configuration improves thermal performance and reduces mismatch losses in partial shading. Anti-reflective coatings on both surfaces enhance light capture at low angles. The panels are PID-free certified and withstand 5400Pa snow loads. Includes 30-year linear power warranty (86.9% at 30 years) and 12-year product warranty. Certified to IEC TS 62941 for bifacial performance testing. The optimized electrical characteristics allow for longer string lengths, reducing balance-of-system costs. Ideal for commercial rooftops, carports, and ground-mounted systems where both sides of the panel receive illumination. The panels maintain performance in high-temperature environments with -0.34%/?C temperature coefficient. The transparent backsheet version weighs approximately 15% less than full glass-glass modules while maintaining structural integrity.
