Abstract A study is reported here of the feasibility of using a mixed solution of dyes as a substitute for a solid selective surface. The criteria for the choice of compounds were fast photothermal conversion and stability. As a result of a preliminary assessment of the photoconversion capability of such a composite system, a collector was designed ...

The Sun position determination is required in several solar applications, within them is the Sun tracking. The Sun position is determined in this chapter with reference to the Earth's center and with reference to an observer on the Earth's surface. This procedure allows determining the possible relationships between different solar angles.

In this investigation, the temperatures of the insulated collector plate and glass cover of a horizontal solar collector were measured and compared to theoretically predicted values for different ambient conditions. By employing an appropriate equation for the prediction of the heat transfer between the cover and the natural environment, good agreement

Abstract In order that tests on different solar collectors conducted at different times shall be comparable, it is necessary that the test define the governing equation of the collector. This involves measurements at different solar intensities, different operating temperatures and different flow rates.
