Abstract
A high solar flux scanner has been designed and constructed to acquire solar flux distribution profile of a non-imaging dish concentrator (NIDC). The scanner is capable of acquiring high concentrated solar flux distribution up to 1182 suns accurately and rapidly using an array of triple-junction solar cells. A numerical simulation has also been developed for modeling onsite solar flux distribution by considering all imperfection factors, i.e. circumsolar radiation, slope error and optical misalignment. A systematic technique has been proposed to analyze the amount of various imperfection factors for the NIDC prototype: mirror reflectivity of 0.93, slope error of 3 mrad, circumsolar ratio of 0.1, and optical misalignment angles of 0.2°.
