The effect of shading on photovoltaic solar panels

The PV module is obtained by series/parallel associations of solar cell circuits. The shading and the mismatch effects between strings of solar cells are the most relevant factors related to the reduction of the collected power P series connected solar cells, if a single solar cell is completely shaded, the power generated by the PV panel vanishes.
