LONGi Solar Panels

LONGi Green Energy Technology Co., Ltd. is a global leader in solar technology, specializing in the manufacturing of high-efficiency monocrystalline solar cells and modules. Established in 2000, headquartered in Xi'an, China, the company has grown from a specialized wafer manufacturer into the world's largest manufacturer of monocrystalline silicon products. LONGi is renowned for its focus on R&D, particularly in Mono-PERC and Hi-MO technology, which has significantly lowered the cost of solar energy worldwide.

While the bulk of its manufacturing capacity is concentrated in China (including facilities in Xi'an, Taizhou, and Ningxia), LONGi has expanded its global footprint to mitigate trade barriers and meet international demand. This includes significant production facilities in Vietnam and Malaysia. The brand is vertically integrated, controlling the process from silicon ingots and wafers to cells and finished solar modules, ensuring high quality and consistent supply chains for utility-scale, commercial, and residential solar projects.
