We consider the feasibility of low-concentration CPC’s for low-temperature applications. A quantitative assessment of optical gains versus thermal losses, and of savings in reflector area, leads to the conclusion that low-concentration CPC’s of relatively small acceptance angle may be competitive with, or superior to, flat plates. Calculations of yearly collected energy and material requirements are presented, and comparisons are made with corresponding flat plate collectors.
