Concentrator photovoltaics (CPV) might as soon as once more turn out to be an economically engaging and high-efficient PV expertise for areas with excessive direct photo voltaic irradiance. To leverage its benefits, Fraunhofer Institute for Photo voltaic Vitality Methods ISE and Soltec have partnered to develop a prototype of a two-axis tracker which is designed to easily combine with Fraunhofer ISE’s newest micro-CPV expertise. Soltec and Fraunhofer ISE plan to put in a primary prototype in Spain by the tip of 2024.
Soltec is a vertically built-in firm specializing within the manufacturing of photo voltaic trackers for large-scale initiatives. Fraunhofer ISE has an extended historical past in analysis on III-V and concentrator photovoltaics. The most recent micro-CPV expertise of the institute reaches 36 p.c conversion effectivity and results in a 30 p.c enhance in power yield in comparison with typical PV options.
The collaboration goals to make use of the superior photo voltaic tracker expertise of Soltec and adapt it particularly to the necessities of a brand new era of Fraunhofer ISE’s micro-CPV modules which function at a focus of almost 1000 suns. The micro-CPV modules place stringent necessities on monitoring accuracy alongside two axes since they have to at all times level precisely to the solar all through the day with a view to obtain the utmost electrical energy era.
“We are preparing the path for the reentry of high-concentration photovoltaics into the market by offering a competitive product which shall convince investors with its high energy yield, robustness and sustainability.” mentioned Dr. Frank Dimroth, division head of III-V and Concentrator Photovoltaics at Fraunhofer ISE. “Resource efficiency is becoming an increasingly important topic in photovoltaics. Compared to the state-of-the-art, our micro-CPV technology reduces module areas by 30 percent and semiconductor materials by 1300 times at comparable power output. This helps to safe precious materials and energy in the production process and therefore improves sustainability.”
“This collaboration between Soltec and Fraunhofer ISE confirms the vision of both institutions. We look forward to continuing our collaboration in the future to further elevate the use of solar energy. These advancements not only represent a step forward in photovoltaic solar energy but also expand its application possibilities across various sectors,” mentioned Eduardo de San Nicolás, Chief Technique and Innovation Officer at Soltec.
The primary prototype might be used to check the precision of monitoring accuracy all through the day. In a later stage, the system may be geared up with 15.7 kWp of micro-CPV panels. The event of the micro-CPV module itself is a part of a research project at Fraunhofer ISE supported by the Federal Ministry of Financial Affairs and Local weather Motion (BMWK).
