Abstract

Concentration PV systems are emerging recently and primary lenses have been developed for concentrating solar incident. Although the authors already produced 500X dome-shaped Fresnel lens, its production process was complicated because of the shape. The objective of this study is to investigate new design method for non-imaging Fresnel with flat upper surface so that the production can be easier. The design of prisms is formulated by means of nonlinear optimization to have maximum acceptance half angle with edge-ray principle. It is shown that designing more than 500X flat Fresnel lens is possible. The study also presents optimal condition of lens size requiring energy payback year to satisfy from the viewpoint of life cycle energy production and consumption.
