PVTIME - LONGi has announced that it has exclusively supplied 200MW of its Hi-MO 5 bifacial modules to the China Energy Engineering Group’s Northwest Electric Power Test Research Institute for a solar project in Ningxia, China. The project, developed by the Ningxia Zhongke Ka New Energy Research Institute, has already entered the construction and installation stage.
Hi-MO 5 series modules are mass-produced in LONGi’s bases at Xianyang in Shaanxi Province and Jiaxing in Zhejiang Province, which respectively has a capacity of 5GW and 7GW. The new-generation product, based on M10 (182mm) standard gallium-doped monocrystalline wafers, has quickly entered the stage of delivery and has gradually begun to be widely deployed at numerous PV projects.
Because of the relief of Ningxia, each rack is only able to carry a limited number of modules (2P fixed rack, 13×2). In this way, the 15m rack ensures construction convenience as well as the decrease of rack and pile foundation costs.
Moreover, the tilt angle, the height of the module from the ground, and the system capacity ratio have a significant impact on the power output of the module. The Ningxia project adopts a 15° tilt design and 535W Hi-MO 5 bifacial modules with an efficiency of 20.9% to maximize installation capacity.
The EPC company reported that, in spite of the certain size and weight of a Hi-MO 5 module, it can be installed smoothly and efficiently, ensuring on-schedule connection to the grid. In terms of electricity, Sungrow’s 225kW string inverter with a maximum input current of 15A is applied in the project, which is perfectly adapted to the 182mm-size bifacial module and can save costs on cables and inverters.
Based on the larger cell (182mm) and innovative “Smart Soldering” technology, the LONGi Hi-MO 5 module made its debut in June 2020. After a short ramp-up in production capacity, cell efficiency and production yield achieved excellent levels comparable to Hi-MO 4. At present, the capacity expansion of Hi-MO 5 modules is progressing steadily and expected to reach 13.5GW in Q1 2021.
The design of the Hi-MO 5 takes into account every parameter in each link to the industrial chain. During the module delivery process, overall installation efficiency is significantly improved. For instance, it takes LONGi team no more than three months to achieve fast and high-quality delivery.
