Comparative study with practical validation of photovoltaic monocrystalline module for single and double diode models

Abstract A photovoltaic (PV) module is an equipment that converts solar energy to electrical energy. A mathematical model should be presented to show the behavior of this device. The well-known single-diode and double-diode models are utilized to demonstrate the electrical behavior of the PV module....
