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 ...

Bypass Diodes are used in parallel with either a single or a number of photovoltaic solar cells to prevent the current(s) flowing from good, well-exposed to sunlight solar cells overheating and burning out weaker or partially shaded solar cells by providing a current path around the bad cell. Blocking diodes are used differently than bypass diodes.

The voltage from the PV module is determined by the number of solar cells and the current from the module depends primarily on the size of the solar cells. At AM1.5 and under optimum tilt conditions, the current density from a commercial solar cell is approximately between 30 mA/cm 2 to 36 mA/cm 2 .
However, that''s one of the many factors engineers must consider when designing a solar photovoltaic (PV) system. For instance, there is still a need to size and choose the ideal solar charge collectors and battery bank and the ideal environment where this solar PV system will be mounted.
Shading of one region of a module compared to another is a major cause of mismatch in PV modules. Mismatch in PV modules occurs when the electrical parameters of one solar cell are significantly altered from those of the remaining devices. The impact and power loss due to mismatch depend on: the operating point of the PV module;
A third approach to increase the resilience against shading consists in connecting PV generators in parallel.
