Semprius has increased its printed micro-cell module efficiency to 35.5% at CSTC. This design has been field tested for more than two years with no measurable signs of degradation. Three different commercial ready CPV systems have been designed, installed and characterized. The pointing error of all three trackers is ±0.1°, well within the module angle of acceptance (AOA) of ±0.8°. The on-sun performance of these systems is consistent with expectations. The peak AC efficiency of the systems was ∼30%.
