Global environmental problem induced by vast amount of consumption of fossil fuels is one of the most important subjects in the world. To solve this problem, utilization of solar energy is one of the most useful methods. Above all, PV system is one of the power generation systems expected to attain this purpose, which is composed of PV modules connecting many solar cells. Power generation of solar cell is affected by the fluctuation of solar radiation and temperature, and actual output is less than that of standard condition. In this paper, analytical considerations is done to obtain the maximum output of PV array under some solar conditions and we obtain maximum conditions from simplified V-I characteristics equations. From the analysis, the output increses by the method we introduced and we defined the characteristics of solar cell for this realization.
