In this paper the experimental study provides first one is, the effect of shading on PV module and second one is, to enhance the power of series and parallel connection of photovoltaic module under shading condition using diode and this diode can be worked as a bypass diode under the series connection of PV module and also worked as a blocking mode under the parallel connection of photovoltaic module. this experimental study evaluates the higher power of photovoltaic module under the shading condition of 1-solar cell, 2-solar cell, 4-solar cell , 9-solar cell and full cover of photovoltaic module cell and also evaluates the power of PV module under the partial shading condition Of 9-solar cell cover above the one feet from the photovoltaic module, these all module or cell shading can remove the power due to shading and these all shading effect can be removed by using diode and improve the power of solar photovoltaic module, result indicates that the power improves approximately between 20%- 30% of solar photovoltaic system under shading condition
