CPV solar tracker prototype to debut in Spain

Germany-based Fraunhofer ISE and Spain-based Soltec are collaborating to develop a two-axis tracker for Fraunhofer’s micro-CPV technology, which offers a 36% conversion efficiency and a 30% increase in energy yield compared to traditional PV solutions. Scheduled for installation in Spain by 2024, the first prototype will test the advanced tracking technology designed to enhance performance at nearly 1000 suns concentration. According to Fraunhofer ISE, this micro-CPV technology significantly reduces module areas by 30% and cuts semiconductor material use by 1300 times, thereby conserving resources and energy. The prototype will incorporate 15.7 kWp of micro-CPV panels to evaluate tracking precision. This initiative aims to rejuvenate high-concentration photovoltaics, enhancing their energy yield, durability, and sustainability, positioning CPV as a leading choice for regions with high solar exposure.
