Study on air convection cooling enhancing photovoltaic performance

Researchers from International University of Lebanese, released a study on air convection cooling for photovoltaic panels. The paper examined the impact of air convection-based cooling methods on PV panel efficiency under Lebanese climatic conditions. It analyzed three cooling types: Forced-PV, Free-Finned-PV and Forced-Finned-PV. For domestic applications, Forced-Finned-PV showed the highest gains: 569.09 × R kWh energy, $244.7 × R savings, and 330 × R kg CO₂ reduction. For power plants, these values were 121045.81 × R kWh, $52049.69 × R, and 70206.57 × R kg respectively. Payback periods ranged from 1.21 to 1.41 years across methods. A linear relationship was observed between efficiency increase and energy, savings, and emission benefits. In July, a 40% efficiency boost correlated with 23.51% savings and 31.71% CO₂ reduction.
