Abstract
This paper presents the effects of optical properties on the performance of flat plate solar collectors. Efficiency is presented for flat plate designs utilizing a single glass cover, two glass covers, two transparent plastic covers, and honeycomb between the cover and absorber plate. The performance of evacuated systems with a single glass cover are compared to the other designs. The effects due to variation in solar transmittance and infrared reflectance of the cover plate and in solar absorptance and emittance of the absorber plate are discussed.
