This paper describes how the effect of thermal and optical properties of the transparent plate on the collection characteristics of a volume heat trap solar collector was studied theoretically and experimentally. for collectors with transparent plates of different material and thickness, the time changes of the temperature distribution were measured in the indoor and outdoor experiments. The calculated results, taking natural convection within the working fluid layer into consideration, were compared with the experimental data. If was found that the collection characteristics of the volume heat trap collector greatly depended upon both the thermal resistance and the transmittance of the transparent plate.
