Quasi Parabolic reflector for a quasi Parabolic Solar Concentrator which comprises a Concave Reflective Surface portion, a First Reflective Mirror, a second portion, where the first Focal area and the second Focal area are a focal distance from the Concave side of the supe Rficie Reflective Concave; method.

摘要

A quasi-parabolic reflector and method are provided for a solar concentrator which produces a unique radiation pattern which is less susceptible to surface defects, less sensitive to target distance irregularities, and having greater uniformity of intensity for PV applications in comparison to that produced by true parabolic reflectors. Cross-sections of the quasi-parabolic reflector include spaced reflective surfaces which have focal areas spaced one from the other about an axis of symmetry. A method for forming petals of a quasi-parabolic reflector includes stamping them into shape using a stamping apparatus with a higher radius of curvature than the finished petal and iteratively testing and stamping the petal until the petal passes or fails a quality and accuracy threshold.
