German solar module maker Heckert Solar, photovoltaic products distributor Wattkraft and Europe's largest solar glass maker Interfloat are planning to invest around 2 billion euros ($2.18 billion) in three different manufacturing plants to produce the full range of products from polysilicon to solar modules .

Thanks to the new investment, the capacity of Heckert Solar's existing plant in Langenweizendorf in Thuringia will increase from 400MW to 2.8GW. In addition, the consortium will build a 5GW facility to produce polysilicon and solar cells at Heckert Solar's plant in Frankfurt an der Oder in eastern Germany.

Furthermore, Interfloat is planning to produce antimony-free low-iron textured solar glass for the combined value-added chain at one of its plants in Brandenburg.

The consortium also said the new production facility will produce glass-to-glass assemblies with efficiencies of up to 24% and a carbon footprint of less than 18 g/kWh, which it says will meet the highest ESG sustainability standards.
