A comparative technical evaluation of the four primary solar collecting configurations, namely, the central receiver, parabolic trough, paraboloidal dish, and "Winston" collector, is made. Subsystem and overall efficiencies are presented, and technical descriptions and performance characteristics are discussed. Comparisons are made on a solar thermal conversion basis. Applicability of the "Winston" collector for photovoltaic conversion is summarized. The most attractive candidate for solar thermal applications from a technical viewpoint is the central receiver configuration with the overall efficiency of 19.2%. The "Winston" collector is more applicable for photovoltaic conversion than for solar-thermal conversion.
