In recent years, solar cells increasingly are using in the buildings to supply the part of required electricity. This device must be inclined to receive a larger amount of energy. It is suggested that solar cell must be installed at tilt angle equal to location latitude as optimum condition. Solar cell is often installed on the roof of the buildings, where the effect of spatial obstacles shadow is minor. However, this important effect is neglected in the time of installation and there is no evidence of its consideration. Effect of spatial obstacle such as building on optimum location and inclination angle of solar cell was investigated in this study. Modeling results reveal that in the case of obstacle existence in both sides ofthe solar cell, optimum location is near to the lower wall and there is no change in optimum inclination angle.
