Abstract
In this study, a solar collector that uses porous media has been designed and constructed as an absorbing and storing heat surface. The solar collector is inclined of ( ) with the horizon. Heat has been absorbed from the collector by forced convection of air. A theoretical and experimental study was made for testing the performance of the collector in continuous operating of an air blower( from a.m to p.m) The highest instantaneous efficiency of the collector was about ( ), while the highest different between air input temperature and air output temperature from solar collector was about( ).
