Soltec and Fraunhofer Institute for Solar Energy Systems ISE are working together to develop a cost-competitive prototype for next-generation concentrating photovoltaics (CPV). This technology could become an economically attractive and high-efficiency solution for regions with high direct solar irradiance. The partnership aims to create a prototype of a two-axis tracker that integrates smoothly with Fraunhofer ISE’s latest micro-CPV technology. The first prototype is planned for installation in Spain by the end of 2024.
Soltec specializes in manufacturing solar trackers for large-scale projects and operates as a vertically integrated company. Fraunhofer ISE has a long history in research on III-V and concentrator photovoltaics. Their latest micro-CPV technology achieves 36 percent conversion efficiency and offers a 30 percent increase in energy yield compared to conventional PV solutions.
The collaboration focuses on using Soltec’s advanced solar tracker technology, adapted specifically for Fraunhofer ISE’s new generation of micro-CPV modules. These modules operate at a concentration of nearly 1000 suns, requiring precise two-axis tracking to maximize electricity generation. Dr. Frank Dimroth, department head of III-V and Concentrator Photovoltaics at Fraunhofer ISE, emphasized the goal of reintroducing high-concentration photovoltaics into the market with a competitive product offering high energy yield, robustness, and sustainability. He highlighted the resource efficiency of their micro-CPV technology, which reduces module areas by 30 percent and semiconductor materials by 1300 times, thus conserving precious materials and energy during production.
Eduardo de San Nicolás, Chief Strategy and Innovation Officer at Soltec, expressed enthusiasm about the collaboration, stating that it confirms the vision of both institutions and represents a significant advancement in photovoltaic solar energy. The first prototype will test the precision of tracking accuracy throughout the day and will later be equipped with 15.7 kWp of micro-CPV panels.
