WebMar 1, 2024 · Curved reflector shows higher performance than a flat reflector. The concentration features are almost the same when reflectors of parabolic and cylindrical shapes are taken into consideration for a similar reference. Higher concentrations are achieved if slightly bent reflectors are aimed toward the absorber central line. WebCPCs are static collectors with an involute reflective surface around a cylindrical reactor tube. They have been found to provide the best optics for systems with a low solar radiation concentration and can be designed with a concentrating ratio close to 1 for capturing both direct and diffuse UV sunlight.
