Abstract: The utilization of solar energy will be more relevant for developing countries whose energy requirements are increasing rapidly as a result of large-scale industrialization covers a large area of multiple applications. Installations of Solar Flat plate collector for tapping solar energy to some useful energy are the most frequently used in various solar thermal systems. From the present work the performances of the system both with and without wind shield were evaluated and compared. In a present solar system by adding the wooden windshields along perimeter of the flat plate solar energy collector creating the heat convective film that minimize the top loss coefficient by increasing the energy gained results enhancement in the heat flow rate from absorber plate to riser tubes. Hence, the efficiency of proposed system is more than the conventional system.
