A Novel Method for Fault Detection and Protection in Solar Photo Voltaic Arrays

With the increased use of photovoltaic (PV) modules, there is a greater demand for quick response and effective PV fault detection methodologies, not just to assure system dependability, but also to cut down on maintenance costs, computational load, and human labour. To improve the efficiency and reliability of solar modules, fault detection and condition monitoring are critical. Manufacturing errors are thought to be the primary cause of performance inconsistencies in some modules. Undetected defects in photovoltaic (PV) arrays have the ability to cause permanent power loss and severe catastrophic failures. Some of the defects that cause damage to the PV arrays are over voltage, under voltage, over current, short circuit, open circuit, blindspot error and hotspot error.
