Chinese photo voltaic module maker Longi unveiled right this moment its newest photo voltaic modules at a press occasion on the ATP Masters in Shanghai.
The Hi-Mo X10 module sequence is predicated on Longi’s proprietary hybrid passivated again contact (HPBC) cell expertise and has an influence conversion effectivity of as much as 24.6%.
The modules can be found in 4 variations with an influence output of 650 W to 665 W. They measure 2,382 mm x 1,134 mm x 30 mm and weigh 33.5 kg. Their temperature coefficient is -0.26% per C.
The new merchandise include a 15-year product guarantee and a 30-year linear energy output guarantee. The modules are designed for an annual linear degradation price of 0.35% over 30 years, with the primary 12 months capped at 1.0%.
According to the producer, these new panels have 1% greater effectivity in comparison with their predecessors. They are constructed utilizing 182mm n-type TaiRay wafers, that are acknowledged as a breakthrough in silicon expertise. These wafers reportedly enhance resistance consistency, cut back steel impurities, and supply superior mechanical energy.
The new merchandise embody Longi’s HPBC2.0 expertise, which incorporates a distinctive bypass diode construction that permits the blocked present to reroute independently when encountering shade, leading to over 70% with much less energy loss in comparison with conventional TOPCon merchandise, based on the producer. In addition, it reduces hotspot temperatures underneath shading circumstances, lowering overheating by greater than 28% in comparison with typical modules.
Another function is the zero-busbar (0BB) design, which eliminates the busbars and gridlines on the back and front sides of the panel. This design maximizes gentle absorption within the entrance and improves the effectivity of mirrored gentle within the again.
At the occasion, Longi additionally introduced that shipments of HPBC merchandise will exceed 10 GW by the top of the primary half of 2024.
