Résumé

At elevated ambient temperatures, the production and efficiency of solar panels are degraded due to the overheating of the cells. Cooling photovoltaic cells at elevated ambient temperatures can prevent overheating, extend their life, and enhance overall efficiency, particularly in areas exposed to strong sunlight and elevated temperatures. In this study, an attempt was made experimentally to increase the performance of solar photovoltaic thermal systems with a novel cooling technique. The proposed system has an absorber plate coupled with novel skeleton-shaped fins used to create double-pass ambient air channels below the solar module for natural heat dissipation. Performance of the proposed photovoltaic thermal system with skeleton-shaped fins was designed, evaluated, and evaluated, under different climatic conditions of the southern Algeria city of Ghardaïa from 8:00 am to 6:00 pm. Theoretical analysis was also developed relying on the energy and exergy balance equations for the system components. An economic analysis is also performed by the life cycle cost analysis to evaluate the feasibility, annual performance, and payback period of the proposed solar system compared with that of the conventional system. Results showed that the proposed photovoltaic thermal generates an average daily production of 2.02 kWh, which is 55.1 % more than the conventional system. The energy and exergy efficiency of the proposed system are higher than the conventional system by 8.61 and 8.98 %, respectively. The levelized costs of energy associated with the proposed system (0.17 $/kWh) is lower than that of the conventional system by 11.76 %. The payback period of the proposed system (6.21 years) is lower than that of the conventional solar systems by 34.7 %. This means that the additional power generation obtained by the proposed system with skeleton-shaped fins was sufficient to offset the total life cycle costs
