Abstract: The operation and accuracy of portable optical measurement equipment for determining the solar absorptance, αs , and emittance, ε, of solar selective surfaces are presented. The optical equipment ...

Abstract: Parabolic trough solar collectors utilize glass envelopes around the receiver tube in order to reduce thermal losses. Antireflective (AR) coatings applied to the envelope can potentially increase ...

Abstract: In imaging solar concentrators, the solar radiation incident on a receiver surface depends upon both the overall concentrator shape and the angular distribution of light rays (sunshape) that ...

Abstract: The sensitivity of the solar weighted optical properties of selected materials to different terrestrial solar spectral irradiance distributions and computational techniques has been investigated. ...
