Photovoltaic cell electrical output is extremely sensitive to shading (the so-called "Christmas light effect"). [45] [46] [47] When even a small portion of a cell or of a module or array of cells in parallel is shaded, with the remainder in sunlight, the output falls dramatically due to internal ''short-circuiting'' (the electrons reversing course through the shaded portion). When connected …
