The SRB solar thermal panel

Abstract

Can one build a solar thermal collector which reaches 400 C even without using focusing mirrors? Yes we can, says SRB Energy, a company aiming at industrially producing a flat panel solar collector patented at CERN in 2003. The distinctive feature of this collector is the high efficiency achieved thanks to the vacuum maintained by a getter pump powered by the sun. © 2013 European Physical Society, EDP Sciences.
