The manufacturer specified the new product relies on ‘zero-busbar’ (ZBB) technology, which it claims ensures maximum light capture and low reflection.

No more technical details on the new product were unveiled. Longi Solar now has a fullrange product portfolio consisting of HiMO 4, HiMO 5, Hi MO N and the new HiRO Onyx, with each product series optimized for different application scenarios,” said the company’s senior vice president, Dennis She.
