He Jiangtao, General Manager of LONGi Solar Technology in Jiangsu said, “The production line at our new 5GW module facility in Taizhou, Jiangsu Province is currently at the highest level in the PV industry, and the per capita output of the facility will also be at the forefront of the industry in the future. According to our estimates, its efficiency will ultimately increase by about 35%, which both ensures product quality and accelerates the production capacity of our M6 (166mm) wafer modules.” 

LONGi had launched its Hi-MO 4 module in 2019 and continued performance upgrades have resulted in outputs of up to 450Wp, with a conversion efficiency of 20.7%.  

Cumulative order intake for Hi-MO 4 modules was said to have exceeded 10GW, with more than 2GW having already been delivered to global customers.

According to LONGi’s production plans in 2020, the 166mm mono module types are expected to exceed 20GW in capacity.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 7-8 October 2025 is our third PV CellTech conference dedicated to the U.S. manufacturing sector. The events in 2023 and 2024 were a sell out success and 2025 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
