Xi'an LONGi Silicon Technology Co., Ltd., was established.

Xi'an Lumei Single Crystal Silicon Co., Ltd. was established.

The first batch of 18 monocrystalline silicon furnaces began operations, with a production capacity of “device-level” mono silicon ingots up to 30 tons per year.

The 1,000 ton Mono Silicon Ingot Project (Phase I) of LONGi was completed in Ningxia.

The company name was changed to Xi’an LONGi Silicon Materials Co., Ltd.

Xi'an Tongxin Semiconductor Accessories Co., Ltd. was established.

The 350MW Mono Silicon Wafer Project (Phase I) of LONGi was built.

The Wuxi Project of LONGi (Phase I) was built, with a production capacity of mono silicon wafers up to 600 MW.

The LONGi Research and Development Center was founded.

LONGi was officially listed on the main board of the Shanghai Stock Exchange (stock code: SH601012). Production expansion was completed, with wafer production capacity growing to to 1 GW. The Ningxia Project of LONGi (Phase II) was built, with a production capacity of mono silicon ingots up to 8,000 tons.

For the first time, LONGi’s annual wafer shipments exceeded 1 GW.

Xi’an LONGi Clean Energy Co., Ltd., a subsidiary of LONGi, was officially established, marking LONGi’s formal entry into the EPC business of solar power plants. LONGi merged with Zhejiang LERRI Solar Technology Co., Ltd. and extended its business to the solar cell and module sector.

Xi’an LONGi New Energy Co., Ltd. (formerly LERRI Solar Energy Co., Ltd.) was registered, and the company began to develop its distributed solar business.

LONGi (Kuching) SDN. BHD., the first overseas production base, was founded. The LONGi Employer Brand was officially released. LONGi New Energy Division of the Thai subsidiary was established.

Li Zhenguo, President of LONGi, proposed the “Solar for Solar” concept of PV power generation for PV products at the 24th U.N. Climate Change Conference, which attracted global attention.

The rated power of the LONGi 72/144 half-cell module exceeded 450 W, setting a new world record.

LONGi was designated as the “solar solution supplier” for the China Pavilion at EXPO 2020 Dubai, UAE. The company’s first building-integrated PV (BIPV) product — ‘LONGi Roof’ -- went into production. LONGi joined in the Climate Group’s RE100, EV100 and EP100 Initiatives as well as the Science Based Targets initiative, or SBTi.
