Fraunhofer ISE and Soltec develop advanced micro-CPV solar tracker
Fraunhofer Institute for Solar Energy Systems ISE and Soltec are partnering to develop a prototype two-axis tracker for Fraunhofer ISE’s latest micro-Concentrator photovoltaics (CPV) technology, with installation planned in Spain by the end of 2024.
Soltec, specialising in solar trackers for large-scale projects, and Fraunhofer ISE, known for its III-V and concentrator photovoltaics research, aim to enhance CPV technology. Fraunhofer’s micro-CPV modules achieve a 36% conversion efficiency, yielding 30% more energy than conventional PV solutions.
The new tracker will adapt to the high-precision needs of micro-CPV modules, which operate at nearly 1000 suns concentration and require exact sun alignment. Dr. Frank Dimroth of Fraunhofer ISE highlighted the product’s high energy yield, robustness, and sustainability, noting significant reductions in module area and semiconductor material usage.
Eduardo de San Nicolás of Soltec expressed excitement about the collaboration, emphasising the advancements in solar energy applications. The prototype will test tracking accuracy, with plans to equip the system with 15.7 kWp micro-CPV panels.
