In this study, the effect of reflective coefficient of different covers on the maximum solar radiation at optimum angles was investigated utilizing a mathematical model. The results showed that the maximum total radiation on the collector inclined at optimum angles increases due to increasing the reflective coefficient of covers. Finally, the results showed that the surface which is covered with the aluminum foil is the best place to install the solarcollector. Using aluminum foil caused the maximum total solar radiation on the collector during the year increases about 5.36% and increases about 9.7% during the winter
