Abstract
A sun tracking solar concentrator includes a one or two-sided linear Fresnel lens imprinted on a rollable sheet that is curved to form as a cylindrical arc surface. A one sided lens has a first zero line or a center point that transmits sunlight through without any refraction. A two sided lens also has a second zero line that is perpendicular to the first zero line. The Fresnel lens may be spooled onto rollers at its two straight ends. The first zero line or the center point may be positioned along the cylindrical arc by rotating one or both of the rollers. This mechanism aimed at providing horizontal tracking of the sun as it moves from East to West. Vertical tracking is accomplished by a tiltable mount coupled to the two rollers.
