The 1KOMMA5° PV Module with Raw Materials from Germany.

70% of all PV modules are produced in China, often using fossil fuels. At 1KOMMA5°, we want to change that and bring the value chain back to Europe by investing in a clean and local supply chain. We start by sourcing the critical raw material polysilicon using renewable energy in Germany.

By 2025, we are working to establish our own production line in Europe and produce up to 5 GW per year.
