Abstract: It is generally assumed that a solar heating system should be sized by minimizing its life-cycle cost. This study shows, however, that the uncertainty in future economic trends makes the results ...

Abstract: Circumsolar radiation is one of several factors, along with optical errors (contour, tracking, etc.), that determine the size and shape of the solar image at the receiver of a concentrating ...

Abstract: This paper describes a novel alternative to the laser ray trace technique for evaluating the optical Quality of focusing solar collectors. The new method does not require any equipment beyond ...
