Solar Heat for Industrial Processes: RefleC Collector Development and System Design
Abstract
Since August 2007, Wagner & Co. Solartechnik together with Fraunhofer ISE has developed a stationary concentrating, double-covered (glass and polymer foil) flat-plate collector with external reflectors for the generation of process heat between 80 °C and 150 °C. The prototype has a one-sided CPC reflector on the lower side, approximated by three flat reflector segments. Its acceptance halfangle is 35° with a geometric concentration ratio of 1.26. The reflectors have a measured reflectivity of 86 % and were subjected to a hail-impact test according to EN 12975-2: 2006 (method two with ice balls), where the material did not show any damage.
