Zhejiang Twinsel Electronic Technology Co., Ltd. is based in China and lists solar panels on Global Trade Plaza. The company offers modules rated at 540 W and 455 W, as well as a general solar panel line referenced as 655bmdg. The 540 W panels use NDS and MBB 210 mm cell technologies, cut-cell encapsulation and an optimized circuit design that is said to improve module power output by 10 %. They are described as compatible with mainstream optimizers and rapid shutdown devices, with a size and weight suited to residential rooftops. The design aims for lower balance-of-system cost and levelized cost of energy, with low voltage and high load capacity for maximum string power. Buyers can send an enquiry through Global Trade Plaza.
