First, SolTrace is used to analyze collector sensitivity to individual optomechanical error perturbations in both the primary reflectors and the receiver assembly. Optical models are implemented in SolTrace, a Monte-Carlo ray-tracing software developed at NREL. Here, this study presents a detailed sensitivity analysis of the optical performance of Hyperlight linear Fresnel technology, characterizing the effects of potential optomechanical error sources on collector performance. The ability to accurately model the complex optical interactions of a collector becomes essential in successfully implementing a new collector technology. The optical performance of a concentrating solar power collector represents the largest loss in the efficiency of the overall system. Hyperlight is currently deploying their linear Fresnel collector technology in a half-acre pilot loop near Brawley, California. A novel, low-cost linear Fresnel collector for concentrating solar power applications is being developed by Hyperlight Energy (Hyperlight) and the National Renewable Energy Laboratory (NREL).
