Abstract
System(s) and method(s) are provided for assembling and utilizing parabolic reflectors in a solar concentrator. Parabolic reflectors assembly starts with a low-cost, flat reflective material that is bent into a parabolic or trough shape via a set of support ribs that are affixed in a support beam. The parabolic reflectors are mounted on a support frame in various panels or arrays to form a parabolic solar concentrator. Each parabolic reflector focuses light in a line segment pattern. Light beam pattern focused onto a receiver via the parabolic solar concentrator can be optimized. The receiver is attached to the support frame, opposite the parabolic reflector arrays, and includes a photovoltaic (PV) module and a heat harvesting element that enable dual-mode energy conversion operation. To increase performance of the parabolic solar concentrator, the PV module can be configured to advantageously exploit a light beam pattern optimization regardless irregularities in the pattern.
