Solar Climatic Atlas of Daily Usability by Variable Sky in Algeria

The purpose of this paper is the estimation of solar radiation conversion systems profitability thresholds installed in several climatic zones of Algeria. For this, a numerical simulation has been developed to estimate the profitability thresholds of solar flat plate collectors by zone as well as the effects of input temperature variation, optical efficiency as well as overall losses on the usability function. Finally, the solar atlases of the average monthly usability have been plotted and the zones favorable to the installation of the solar flat plat collectors are identified.
