The effect of shading on photovoltaic solar panels
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. In series connected solar cells, if a single solar cell is completely shaded, the power generated by the PV panel vanishes. To mitigate this problem, bypass diodes (BP) are used (Fig. 2).
