Comparison of the Efficiency of Three Types of Solar Collectors

Résumé

Solar energy is one of the most abundant resources energy available in the world. Solar collectors have evolved in the last decades, but still they haven’t reached very high efficiencies.
The collector efficiency is dependent on the temperature of the plate which in turn is dependent on the nature of the fluid flow inside tube, solar isolation, ambient temperature and top loss coefficient, the emissivity of the plate and glass cover. This paper presents the test results of three different solar collectors and compares their efficiency.
