The intermittentIntermittent nature of a PV system inherently hinders its performance. Maximum power point trackingMaximum Power Point Tracking (MPPT) is a well-established methodology that effectively improves the powerPower delivery capacity of PV systems. This technique optimizes the operationOperation of the PV system by ensuring that it operates at its maximum powerMaximum Power output, taking into account the prevailing temperature and irradianceIrradiance conditions. This study presents a novel sliding modeSliding mode approach for accurately tracking the peak output of a PV system in the presence of variationsVariation in irradianceIrradiance and temperature.
