Abstract
This study investigates the performance of a power generation system that integrates solar flat plate collector systems (SFPC) with thermoelectric generators (TEGs) under standard operating and environmental conditions to enhance the utilization of renewable energy sources. The system utilizes a vacuum-type collector and a stagnant fluid enhancer mixture comprising 50% ethylene glycol (EG) and 50% water 2 within the copper tube absorber to absorb heat from solar radiation. At approximately 10:00 a.m., the system achieves a maximum power generated of 13 V and 1.5 amps at an external temperature of 34°C, showcasing its capability to capture solar energy effectively. Additionally, the study emphasizes the significant role of the differential temperature between the upper and lower layers of the SFPC in maximizing power production, with the optimal range identified between 75 and 100°C. The generator efficiency of the system reaches 2.69%, surpassing the typical 2% efficiency of standalone thermoelectric generators. However, it is noted that increasing the temperature on the low side of the SFPC results in a decline in the average power generated by the TEGs. This research highlights the dependency of the TEG-SFPC system's energy efficiency on solar irradiation levels and ambient temperature fluctuations, offering valuable insights for enhancing the performance of such integrated systems.
