LONGi is a huge Chinese company that supplies silicon products for the electronics and photovoltaic industries. They also manufacture their own photovoltaic modules under the LONGi Solar brand. They are probably the largest manufacturer of monocrystalline panels in the world. LONGi was founded in 2000 and initially focused on the production of silicon wafers, the starting material for monocrystalline cells. In 2007, they acquired the Chinese solar panel brand Lerro Solar and since then have also been manufacturing complete photovoltaic modules, and since 2017 under their own brand LONGi Solar.
