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.
