Abstract

We derive analytic expressions for the geometric characteristics of extremely asymmetric nonimaging solar concentrators ("asymmetric CPCs") with tubular receivers, of fixed maximum concentration ratio C_max. We show that, at fixed C_max, there are nonideal concentrator configurations that minimize reflector area and average number of reflections, and determine configurations that are approximately optimal (maximizing yearly energy delivery at minimal material requirements), independent of climate and economics.
