LONGi Green Energy Technology Co., Ltd. was founded in 2000 in Xi'an, China, and has since become a world leader in monocrystalline silicon wafer and solar module manufacturing. The company's mission is to "make the best use of solar energy to build a green world."

LONGi has built a complete vertical production chain — from silicon ingots and wafers to cells and modules — and its products include the Hi-MO series of high-efficiency modules, as well as BIPV (Building Integrated Photovoltaics) and “Green Power + Green Hydrogen” solutions. The company also focuses on energy storage and hydrogen energy as parts of the future energy system.

LONGi has a strong global presence, with manufacturing facilities in China, Vietnam and Malaysia, and products sold in over 130 countries. It regularly sets new world records in solar cell efficiency (e.g. 34.85% efficiency for a perovskite-silicon tandem cell) — demonstrating its commitment to technological excellence.
