Abstract
In this work it is developed theoretical model which utilizes the Oppenheim concepts of surface and spatial resistances for thermal radiation transfer on solid surfaces in order to determine the heating performance of plane-concentrators solar collectors. It is shown that the shape factor for trapezoidal geometries, which includes the reflecting surfaces, may be utilized to determine the solar concentration chamber effective absorptivity with reasonable degree of accuracy. The experimental results measured on 2:1 plane-concentrators confirm the theoretical values. (author). 13 refs., 5 figs
