LONGi Green Energy

The Xi'an company that bet in 2000 that solar would run on monocrystalline silicon rather than the cheaper multicrystalline wafers that dominated the industry, drove the cost of mono wafers down with diamond-wire sawing and sheer scale until multi all but disappeared (by ~2020), bought its way into modules with Lerri Solar (2014–15) and became, by 2020–22, the world's largest module shipper (industry rankings, reported). Then the industry it helped build overbuilt: China's polysilicon-to-module capacity ran far ahead of world demand, module prices fell to ~$0.10/Wdc (China export, 2024) and LONGi lost ~CNY 8.6bn in 2024 — its first annual loss in twelve years — then ~CNY 6.4bn in 2025 and ~CNY 3.7bn in H1 2026 (company, reported). Its answer is back-contact (BC) cells; its US story runs from UFLPA detentions (2022–23) and Southeast Asian tariffs to a minority stake in Illuminate USA, a ~5 GW module factory in Ohio. LONGi is the book's case that winning the cost war does not guarantee profits in a glut.
