Simulation based analysis of the partial shading at different locations on polycrystalline PV array

Photovoltaic (PV) technologies have definite environmental advantages over other power generation techniques. No matter many are used, PV emits no emissions. Solar cells and modules produced using a variety of manufacturing techniques, as with any energy source or product, there dangers to the environment, human health, safety associated these processes. Like device, even go under degradation due numerous reasons. Shading is one such mode degradations which directly impact output system. Along that drastically get impacted. There drop in electrical characteristics gets distorted. During shading condition curves,Power - Voltage Current-Voltage curve seen unusual peaks exact reason for presence module. The paper presents various on curves confirm loss shading.
