Abstract
This paper deals with the suitability of Fresnel lenses of imaging and nonimaging designs for solar energy concentration. The paper's scope is the review of long known, and recently developed Fresnel lenses, and the analyses of their characteristics for utilization as solar concentrators, putting an emphasis on a lens designed by the authors. Nonimaging optics are presented as offering the possibilities needed for a breakthrough of Fresnel lenses in commercial solar energy concentration, both in photovoltaic and thermal power conversion.
