The result of this work is atheoretical and mathematical analysis of the unsteady thermal regime of flatsolar collectors on the modes of operation under consideration. Based on theresults of the analysis, it is possible to optimize individual structuralelements, as well as to predict the thermal regime and select alternativesolutions for the design of flat solar collectors and the choice of operatingmodes.
