Efficiency Enhancement of PV System Integrating Thermoelectric Generators and Automatic Cleaning System

This paper presents a comprehensive design aimed at enhancing the efficiency of photovoltaic (PV) systems through the integration of thermoelectric generators (TEGs), automatic cleaning systems, and PV sun tracking mechanisms. TEGs are employed to capture and convert waste heat from PV panels into additional electricity, thus, increasing the system's output. The automatic cleaning system ensures that panels remain dust-free, mitigating performance degradation caused by dust accumulation. Concurrently, PV sun tracking maximizes energy captured by dynamically aligning panels with the sun's trajectory. The result shows through the proposed system, maximum energy capture of PV is ensured, which is 38.14% by maintaining surface cleaning, sun tracking, and optimizing the wastage of heat. A prototype was built to monitor the increase in efficiency in real life.
