Soltec, a leading provider of solar tracking systems, and the renowned Fraunhofer Institute for Solar Energy Systems ISE have joined forces to develop a cost-competitive prototype for the next generation of concentrating photovoltaics (CPV).
This emerging technology holds the potential to become a highly efficient and economically viable solution for regions blessed with abundant direct solar radiation.
Combining Expertise for Enhanced Solar Efficiency
Soltec, specializing in the manufacture of solar trackers for large-scale projects, brings its vertically integrated expertise to the table.
Meanwhile, Fraunhofer ISE boasts a rich history in research on III-V semiconductors and concentrator photovoltaics.
Their latest micro-CPV technology has achieved an impressive 36% conversion efficiency, offering a remarkable 30% increase in energy yield compared to traditional photovoltaic (PV) solutions.
Precision Tracking for High-Concentration Modules
The collaboration centers on leveraging Soltec’s advanced solar tracker technology, specifically adapted to meet the unique requirements of Fraunhofer ISE’s new generation of micro-CPV modules.
These modules operate at an exceptionally high concentration of nearly 1000 suns, necessitating precise two-axis tracking to optimize electricity generation.
Dr. Frank Dimroth, department head of III-V and Concentrator Photovoltaics at Fraunhofer ISE, emphasized their mission to reintroduce high-concentration photovoltaics into the market with a competitive product that delivers high energy yield, robustness, and sustainability.
He highlighted the resource efficiency of their micro-CPV technology, which reduces module areas by 30% and semiconductor materials by a factor of 1300, thereby conserving valuable resources and energy during production.
