In this study, we give an overview of different approaches for Photovoltaic module temperature prediction by comparing different theoretical models with experimental measurements. These temperature models are calculated using meteorological parameters such as environment temperature, incident solar irradiance and wind speed if necessary.
PV module temperature (°C) described as a function of weather data and empirical parameters. solar rad iation intensities. The Sandia cell temperature model estimates cell temper a- about °C at an irradiance level of = 1000W/m². The module temperature is PV module or cell temperature (see Table 2). They are based on material properties
The temperature distribution in the PV module was calculated using the Ansys Transient Thermal software package, and the already confirmed empirical equation [10, was used to calculate the output power of the PV module.
The temperature of the solar PV module is decreased by providing water spray using mini DC water pumps. In this project, an experimental setup is designed in which a spray of water tube is fitted to the back of the solar panel to reduce its temperature and bring the temperature to a normal operating point.
In a steady-state controlled environment, the experimental results show that the measured voltage, current and its power decrease with time as the temperature of the photovoltaic panel increases. As a result, the efficiency of the photovoltaic module will decrease progressively.
Previous studies have reported that it is difficult to apply a single model or a unique formula to precisely calculate the PV module/cell temperature [9,11, 18, 19]. Moreover, the thermal characteristics of PV modules are slightly different even if they are manufactured with the same technology and materials [12,13]. ... ...
