New physical PV array arrangements are proposed to mitigate partial shading effects. Performance analysis performed under a range of cloud and shading pattern scenarios. Shifted PV arrangements power-voltage curves exhibit a single peak. Global Maximum Power Point is readily determined. Power dissipation is reduced and energy output is optimized.
