Transmissivities, as a function of incident solar angle, were experimentally determined for various commercially available cover-plate materials using actual outdoor and indoor simulated solar conditions. The glazing materials tested were float glass, plexiglass, fiberglass, and several window films. Since the optical properties of many of these materials are not readily available, the transmissivities could not be calculated analytically. Therefore, the experimental method proved to be invaluable. Furthermore, transmissivities determined from indoor data were found to be in close agreement with outdoor results, making the simulator a practical tool. The transmissivities determined and the methods provided in this paper can be valuable in the design of solar collectors.
