Mitigating impact of partial shading on photovoltaic array configuration by using rearrangement

This paper proposes a photovoltaic model which is presented by using single diode. The photovoltaic array configuration is considered based on the effect of irradiance and temperature. The different sunlight intensity on the photovoltaic array will generate multiple maximum power points. These multiple maximum power points are basically lower than the maximum power point in unshaded condition. Therefore, the methodology of photovoltaic array arrangement is important. In addition, the comparison of electrical power based on patterns of shaded modules in photovoltaic array and the proposed arrangement method are analyzed. The results indicate the proposed method of arrangement can increase the generated power more than the patterns of shaded modules without rearrangement. The multiple maximum power points can be reduced to become a single maximum power point with higher generated power.
