Shading a solar cell is similar to introducing a clog in a water pipe. The clog restricts the flow of water through the entire pipe. Similarly, when a solar cell is shaded, the electrical current through the entire string can be reduced. This is significant because every PV cell in the cell string has to operate at the current set by the shaded ...
