Solar module manufacturer Heckert Solar, PV inverter supplier Wattkraft Systems and solar glass manufacturer Interfloat Corporation have joined hands for GW-scale vertically integrated production plans in Germany.
The trio plans to invest €2 billion to realize the silicon to module manufacturing ambition in 3 locations.
According to the plan, Heckert's existing module production capacity in Langenwetzendorf, Thuringia will be scaled up to 2.8 GW/year with the expansion of an existing production hall and addition of a new one. Currently, the module fab operates 400 MW/year capacity (see 400 MW Solar Fab Online In Germany).
Heckert's existing buildings at Frankfurt's Oder location will also be modified for cell production, and to set up polysilicon production, including wafer production, each with an annual volume of 5 GW.
They aim to produce glass-glass PV modules with 24% efficiency using new cell technologies, which the partners did not reveal. They claim the modules will be low-cost and come with a guaranteed carbon footprint lower than the required 18g/kWh, while complying with the highest ESG standards.
Interfloat, part of India's Borosil Renewables now, will manufacture the world's '1st' antimony-free, low-iron, textured solar glass for the combined value chain at its Brandenburg location, they added (see Environment Friendly Solar Glass From Interfloat).
"The aim of the three consortium partners is to cover at least 90% of the added value in Germany in order to achieve more influence on module and cell development and, above all, greater independence from global suppliers," stated Heckert. "This is the only way to create resilient and diversified module production in Germany and Europe."
The consortium is seeking government support for these manufacturing plans via the Federal Ministry of Economics and Climate Protection's (BMWK) 10 GW manufacturing tender for lighthouse projects (see Germany Launches Big Solar PV Industry Tender).
Another European cell and module manufacturer Meyer Burger is also in the running for the German tender for its 5 GW INTEGRA project (see Meyer Burger Produced 302 MW Modules In H1/2023).
