This paper focuses on the possibility to improve the performances of the photovoltaic (PV) modules through the passive cooling of photovoltaic cells, using phase change materials (PCMs.) In particular, the use of two organic PCM to reduce the temperature rise in PV module has been investigated by numerical simulations. A two-dimensional fluid dynamic simplified model has been developed in Ansys Fluent software to characterize the thermal behavior of the PV module where the PCM is incorporated (PV-PCM), as well as for a benchmark PV module. The results show that PCMs allow to achieve better performance if compared to PV modules without PCM, with an increase in terms of peak electric power even higher than 9% and in terms of daily energy of about 5% all year round, except for winter. Moreover, the dynamic analysis performed for several days allows to evaluate the effective performance of the PV-PCM, taking into account the real degree of solidification achieved during the night. This analysis shows that the use of PCM with low melting temperature does not guarantee complete solidification during the night and this limits its effectiveness during the day.

“…The pump and the fans used consumed power, so cooling using fins was the most efficient process. Some researchers [17][18][19][20] have presented brief reviews of the different cooling methods and their effects on the efficiency of PV systems, with a view to minimizing the working temperature of PV cells and improving efficiency. Li et al 21 presented a thermal-electric coupled model for PV panels to assess a passive radiative cooling and selective spectral cooling effect under variable conditions.…”

A parametric study of a photovoltaic panel with cylindrical fins under still and moving air conditions in Iraq

Photovoltaic (PV) panel temperature plays a vital role in the performance of PV panels. When PV temperature increases, the electrical power and efficiency decrease. In the present study, a simple simulated model is derived and implemented for a 70-W finned PV panel and the results are compared with those for a reference (unfinned) PV panel. The effect of various parameters including fin diameter, fin height, ambient temperature, fin coverage-to-area ratio, and solar irradiance level on PV performance are examined. It is concluded that more electrical power is generated under moving air than under still air conditions as solar irradiance increases. The optimum values for fin diameter, fin height, and fin coverage-to-area ratio are 0.005 m, 0.25 m, and 50%, respectively. The maximum simulated power difference between the finned and unfinned PV panels is 5 W under realistic weather conditions. The amount of power generated during the summer season would be about 3.32 kW•h greater than that by the reference PV panel over the same period. The root square percent deviation values between the results of the proposed model and previously published experimental data for panel temperature, electrical power, and electrical efficiency are 3.36%, 5.26%, and 5.48%, respectively.

“…In the literatures, a comparison of various methods for cooling PV panels has also been made [20][21][22]. Heat removal in these cases has been carried out, among other methods, using heat sinks, heat pipes, phase change materials (PCMs), air cooling, jet impingement cooling, or water spraying on the panel walls.…”

Photovoltaic Roof Tiles: The Influence of Heat Recovery on Overall Performance

2019

A photovoltaic (PV) roof tile serves both as a roofing material and as an electricity-producing surface. The main aim of the present study was to increase the overall system efficiency of PV tiles by using heat recovery. The chosen strategy was two-fold: determine the operational efficiency of PV tiles and optimize construction to increase the cooling effect when using air as the working medium. A detailed experimental study was undertaken to determine these effects. The results indicated that a combined electrical and thermal efficiency of 24% could be reached. This is promising and proves the potential for air to be the working medium in such systems. Moreover, this shows a direction for future system optimization.
