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

LONGi has built a complete vertically integrated manufacturing chain – from silicon ingots and wafers to cells and modules – and its products include the high-efficiency Hi-MO series 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 integral parts of future energy systems.

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