Since 1978, the ENTECH technical team has been developing, field testing, refining, and commercializing photovoltaic concentrator systems based on a patented arched Fresnel lens optical concentrator, which provides maximum optical efficiency coupled with exceptional real-world error tolerance. First- through third-generation systems were deployed from the early 1980s to the early 1990s. In 1991, ENTECH was awarded a contract by Sandia National Laboratories to develop a fourth-generation concentrator module. In 1992, ENTECH was funded by NREL under the PVMaT Phase 2A procurement to develop and implement the manufacturing process for the new module. This report documents the work performed by ENTECH, Inc. under this PVMAT Phase 2A program.
