Abstract:

Solar photovoltaic (PV) systems typically exhibit reduced efficiency due to variable weather conditions and thermal losses.      This study examines a unified method to improve photovoltaic (PV) efficiency by incorporating thermoelectric cooling (TEC) modules with offline Maximum Power Point Tracking (MPPT) in a multi-string inverter setup.      The offline MPPT methodology employs adaptive data-driven tuning and established optimization methods to ascertain the maximum power point (MPP) under varied temperatures and irradiance levels.     It is not necessary to engage in mathematical calculations constantly.      This technology ensures the steady and efficient collection of energy while utilizing fewer computational resources and facilitating system management.      The Peltier effect is employed by thermoelectric cooling modules to efficiently dissipate excess heat from photovoltaic panels.     This maintains the cell at the optimal temperature and enhances the efficiency of the energy conversion process.      TEC modules are effective in temperature regulation in various environments because to their portability, low power consumption, and versatile applications.      The multi-string inverter configuration enables optimization at the string level, thereby addressing issues related to partial shading, mismatch losses, and uneven irradiance.      Both laboratory and field trials demonstrate that the proposed integrated system significantly enhances energy yield, thermal stability, and overall system reliability.      The findings indicate that integrating offline MPPT, thermoelectric cooling, and multi-string inverter technologies could significantly enhance the efficiency of photovoltaic systems.   This could represent a significant advancement for scalable solar energy systems that are environmentally beneficial
