    Abstract

    The purpose of this work is to determine the improvement of the solar collector efficiency of a flat plate collector, at incident angles between 0° and 90°, by adding an antireflective coating to its normal low iron glass cover. And to determine the transmittance, at incident angles between 0° and 90°, for the low iron glass with and without the antireflective coating.The solar transmittance for a low iron glass without and with an antireflective coating will be measured at incident angles between 0° and 90° in an outdoor test facility which can track the sun.A flat plate solar collector will be tested in the same test facility. First with the normal low iron glass cover and afterwards with the glass with the antireflective coating. The solar collector efficiency for the solar collector with the two covers will be measured at different angles of incidence.The improvement of the solar transmittance by adding an antireflective coating to a normal low iron glass will be shown at different angles of incidence.The improvement of the solar collector efficiency for a flat plate solar collector by changing the normal low iron glass cover to a normal low iron glass with antireflective coating will also be shown at different angles of incidence.
