Opto-geometric performance of fixed-focus solar concentrators

摘要

In this paper, the opto-geometric performance of fixed-focus solar concentrators (FFSCs), namely, the high temperature concentrator (HTC), the Scheffler concentrator and the Scheffler-type solar concentrator (STSC), is analysed. The goal of this study is to determine the behaviours of FFSCs as a function of their dimensions and to compare the results to the results of parabolic dish (PD) solar concentrators. An algorithm based on opto-geometric models of these concentrators was developed, and numerical calculations were performed for each type in a range of thermal power of 1-50 kW.
