Analysis on Concentrating Radiation Transfer to Solar Array with Concentrator

An algorithm of ray tracing Monte Carlo method was developed to simulate concentrating characteristics of solar radiation transfer to solar array with an ideal shape solar concentrator (ISSC). The effects of the solar angle, slope error and tracing error on the concentrated solar flux were investigated, and a uniformity factor is defined to evaluate the concentrating solar beam. The results of calculation show that the non-uniform factors lie in the range from 0.6 to 0.8 under these influencing effects.
