Chinese solar panel manufacturer Longi has unveiled a new module series based on its patented hybrid passivated back-contact (HPBC) cell technology.
The company has yet to explain exactly what HPBC is, but it is believed to be an extension of the p-type interdigitated back-contact (IBC) technology that combines the structural advantages of PERC, TOPCon and IBC solar. Furthermore, BC technology can be combined with p-type wafers, for which Longi has significant production capabilities, giving it an advantage over the more common IBC technology.
The new Hi-MO X6 Scientist panel is available in three versions with output power from 620 W to 630 W and energy conversion efficiency from 23.0% to 23.3%. The no-load voltage is between 52.72 V and 53.02 V and the short-circuit current is between 14.93 A and 15.07 A.
The modules have a temperature coefficient of -0.28%/C and a maximum system voltage of 1,500. Their dimensions are 2,382 mm x 1,134 mm x 30 mm and their weight is 28.5 kg. They also feature IP68 junction boxes, anodized aluminum alloy frame and 3.2mm coated tempered glass.
The new products come with a 25-year linear performance warranty, with the The final power over a period of 25 years is guaranteed not less than 89.4% of the rated output power.
“The Hi-MO Longi in a statement. “The Hi-MO X6 series entered mass production in the current quarter, with a full transition for all mainstream products expected in the third quarter of 2024.”
In March, Longi launched its Hi-MO X6 Explorer and Hi-MO X6 Guardian modules.
