Photovoltaic applications worldwide have reported problems with shading. Passing clouds, the moving shade of a neighbor's chimney or nearby tree, can completely compromise power production such plants despite their size sophistication. In order to address this issue, paper makes an exhaustive study available interconnections among modules shaded photovoltaic field and how they impact production. As result, clear relationship between PV output is proposed through empirical connection laws.
