Last modified: June 10, 2024 Researchers have created a comprehensive model of the circular water flows in a solar cell factory with a production capacity of 5 gigawatts (5GWp) per year. The results show that a reduction of up to 79 percent in the water consumption and up to 84 percent in the wastewater is possible.
Researchers from the Technical University of Berlin, Rena Technologies GmbH, and the Fraunhofer Institutes for Building Physics IBP and for Solar Energy Systems ISE have for the first time created a comprehensive model of the water flows in a solar cell factory with a production capacity of 5 gigawatts (5GWp) per year.
