“…Failure can occur because the shaded cell(s) are now acting as a load instead of a generator. A bypass diode is used to prevent this from happening by rerouting the current away from the shaded cell(s) and into the load [22]. Figure 13 illustrates a single cell that experiences partial shading, while Figure 14 displays the P-V curve of a PV module with multiple maximum power points (MPPs) when partial shading occurs and the bypass diode is activated, resulting in global and local peaks.…”

The ever-increasing demand for electrical energy in recent decades has necessitated the exploration of alternative energy sources, one of which is solar energy. The most practical means of utilizing solar energy is through the use of a Photovoltaic (PV) system. Nevertheless, the energy harvested by PV modules is constrained by low conversion efficiency, nonlinearity, and susceptibility to weather conditions, such as temperature and irradiance levels. To address these limitations, Maximum Power Point Tracking (MPPT) techniques have been developed to optimize the output of PV systems under specific circumstances. This academic article provides an in-depth analysis of the most widely used MPPT techniques, utilizing both traditional and soft computing methods. The article discusses the fundamental principles and practical applications of these techniques, as well as the challenges associated with MPPT, such as coping with rapidly changing irradiance and partial shading scenarios.
