“…Second Order Upwind was selected in momentum and energy equations. A convergence criterion of 10 -5 was applied to the residuals of continuity equations while for the momentum and energy ones was 10 -6 [23]. The model was developed to evaluate, on each surface, both the weighted average temperature T value and the temperature distribution T (xi, Ti), reported in Eq.…”

Ventilated Faç ades integrating photovoltaic panels are a promising way to improve efficiency and the thermal-physical performances of buildings. Due the inherent intermittence of the non-programmable renewable energy sources, their increasing usage implies the use of energy storage systems to mitigate the mismatch between power generation and the buildings' load demand. The main purpose of this paper is to investigate the thermo-fluid dynamic performances of a prototype integrating a photovoltaic cell and a battery as a module of an active ventilated faç ade. Based on an experimental setup, a numerical study in steady state conditions of flow through the air cavity of the module has been carried out and implemented in a fluid-dynamics Finite Volume code. In order to assess the viability of the prototype, the calibrated model was lastly used to predict thermal performance of the prototype on different climate conditions supporting its further improvement.

“…Numerous thermal models have been developed to estimate the effect of heat load on temperature, and consequently, the energy yield. Goverde et al [20] performed wind tunnel experiments that indicated that the spatial temperature variations caused by wind should be considered for accuracy yield evaluation. Prilliman et al [21] then developed a fast transient thermal model that accounts for transient climatic conditions and thermal mass of module, which improves energy production prediction.…”

Thermal Effects on Photovoltaic Array Performance: Experimentation, Modeling, and Simulation

et al. 2021

The performance of photovoltaic (PV) arrays are affected by the operating temperature, which is influenced by thermal losses to the ambient environment. The factors affecting thermal losses include wind speed, wind direction, and ambient temperature. The purpose of this work is to analyze how the aforementioned factors affect array efficiency, temperature, and heat transfer coefficient/thermal loss factor. Data on ambient and array temperatures, wind speed and direction, solar irradiance, and electrical output were collected from a PV array mounted on a CanmetENERGY facility in Varennes, Canada, and analyzed. The results were compared with computational fluid dynamics (CFD) simulations and existing results from PVsyst. The findings can be summarized into three points. First, ambient temperature and wind speed are important factors in determining PV performance, while wind direction seems to play a minor role. Second, CFD simulations found that temperature variation on the PV array surface is greater at lower wind speeds, and decreases at higher wind speeds. Lastly, an empirical correlation of heat transfer coefficient/thermal loss factor has been developed.

“…Edgar et al [5] show that passive convection cooling of PV modules can improve electrical power by 2% under nominal operating conditions. Goverde et al [6] conducted an experimental study varying the irradiation of the PV panel and the wind speed between 1 and 5 m/s. They found that the temperature of the module as well as the coefficient of convective heat transfer were significantly affected by the wind.…”

Numerical study of the effect of wind on the cooling of photovoltaic panels

The main objective of this study is to optimize the production of electricity from a photovoltaic (PV) plant with a capacity of 50MWc. The power plant is located near the city of KITA, Mali, in an area whose climate is characterized by high temperatures. However, the temperature of photovoltaics cells plays a key role in their performance, which deteriorates when the temperature increases. In this study we focus on the analysis of laminar forced convection flow around a PV panel, main element of a photovoltaic plant, considering the ambient temperature, irradiation as well as the velocity and the direction of the wind. Several operating configurations were analysed in relation to the specific climatic conditions of Mali for a typical day of sunshine with a daily irradiation of a duration of 12 hours between 6:00 and 18:00. The mass transport, momentum and energy equations are solved numerically using the finite volume method. This method is based on the spatial integration of transport equations with respect to elementary control volumes. Computer simulations are performed with ANSYS Fluent® CFD commercial software. Our results show that considering the effect of wind plays an important role in the temperature estimates of photovoltaic cells and that accurate knowledge of this behaviour is essential for optimizing production.
