Longi brings special 66-cell solar panels to Europe
Longi's new units are based on M10 wafers with 66 solar cells and a new chassis. The special configuration of the unit allows installation in a horizontal format, as the panels can also be fixed on the short side of the frame.
Longi has added another half-cell model to its HiMO5 line of monocrystalline solar modules.
The new product is based on M10 wafers with 66 solar cells and a new chassis. The Chinese solar panel maker said it was developed specifically for the European market photovoltaic. The special module configuration also allows installation in a horizontal format, as the panels can also be attached to the short side of the frame, he added, noting that he designed it this way to optimize the installation of solar modules in ground-mount systems.
Longi claims that the new units make system planning significantly more flexible, especially in the power plant segment, thanks to the horizontal orientation format. The units are compatible with standard market mounting systems.
By choosing to mount it on the short side of the frame, there is less installation and material expense than conventional solar panels of comparable size. For example, Longi noted that six-row horizontal layout systems can be implemented, which would otherwise require significantly more mounting rails and unit clamps.
PERC cells
PERC solar cells improve performance by depositing an additional passive coating and laser grooves on traditional cells. LONGi launched mono-PERC modules in 2016, with integrated PERC technology in monocrystalline silicon and low-light degradation, and its cell efficiency has increased from 21% to 24,06%.
Two-person PV
Bifacial modules collect solar energy from both the front and back of the module, increasing the total power output per module. LONGi had started large volume production of duplex units and has become the largest producer photovoltaic of duplex products, with duplex units exceeding 20 GW in early 2021.
Half cut technology
Higher Power & Higher Reliability: The half-cut technology adopts the infrared laser to cut the high-efficiency cells from one to two to halve the current. Finally, heat losses will be significantly reduced and the efficiency of the unit could increase by 2%. Reducing the working current of the cell increased the reliability of the unit at the same time, especially the higher current double sided cells.
