Abstract

Semprius manufactures HCPV modules with printed microcells that provide cost, performance, and reliability benefits over conventional flat-plate modules. Recent module results exceed 35% efficiency at concentrator standard test condition and current factory built modules average 33%. Semprius has installed several different reference HCPV systems with apertures that range from 54 m²-140 m², suitable for commercial deployment. This paper outlines Semprius´ system design approach and presents field results including system efficiency, power production, and tracker error. Results confirm an ac system efficiency of 30%. In addition, Semprius´ performance model will be described and results presented.
