Abstract:
Solar energy is one of the most promising renewable resources, playing a vital role in addressing
environmental challenges and meeting the growing global electricity demand. However, the performance
of photovoltaic (PV) systems remains constrained by various environmental factors. This study
investigates the impact of three integrated solar techniques on enhancing PV panel performance: the solar
concentrator, the aerovoltaic system, and the solar oven. Experiments were conducted in Annaba,
Algeria (geographic coordinates: 36.9° N, 7.77° E).
The adopted methodology involved designing, building, and testing functional prototypes. Results
showed that the aerovoltaic system achieved a net power output of 86.07 W, compared to 84.36 W in the
standard setup, while performance dropped to 23.76 W without ventilation—highlighting the role of
active cooling. The solar concentrator reached a peak power of 0.403 W under 715 W/m2 irradiance with
22.5% efficiency, rising to 28% under 510 W/m2. The solar oven allowed for stress testing at extreme
temperatures up to 117°C, providing insights into PV thermal durability. These findings confirm the
effectiveness of the studied techniques in improving photovoltaic efficiency and reliability under diverse
environmental conditions.
