Shading losses in PV systems, and techniques to mitigate them

Solar photovoltaic (PV) systems generate electricity via the photovoltaic effect — whenever sunlight knocks electrons loose in the silicon materials that make up solar PV cells. As such, whenever a solar cell or panel does not receive sunlight — due to shading or nearby obstructions — the entire installation generates less overall solar power.

The effect of shading on photovoltaic solar panels

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).
