Ray-trace analysis of the low-CR concentrator shows that its optical performance is quite forgiving of moderate pointing error. Ray-tracing also identifies the upper reflector corners as the source of reflector heating. Making these zones nonspecular could produce lower, more uniform reflector temperatures with a small sacrifice in optical efficiency. A coupled thermal-electrical analysis of a typical concentrator element within the large array shows that nonuniform illumination need not produce significant mismatch losses provided that solar cells are connected in parallel groups across the half-panels. In general, the ground test results of a prototype concentrator conform with theoretical predictions which take into account known environmental and design factors. The predicted insensitivity to pointing angle is confirmed.
