Optical and thermal modeling of a photovoltaic module and experimental evaluation of the modeling performance

Abstract

In the present study, coupled optical and thermal models were used to predict the temperature distribution of photovoltaic (PV) module's layers. To verify the modeling performance, an experimental measurement was also conducted in this study and temperatures of two PV modules fixed at 10° and 30° tilt angles were measured and compared with the predicted module temperatures. Two extra experimental data sets measured in two other locations of the globe were also used to further verify the modeling performance. The modeling prediction was also compared with the results of other mathematical models developed in the past studies. This study paid a special attention to the prediction of air convection heat transfer coefficient over the PV module as well as the optical and thermal modeling. The results of this study showed that the present modeling predicts the PV module temperature with a reasonable accuracy compared to the experimental data measured in this study and the other data sets measured in the other parts of the globe. The results also showed that the present modeling predicts the PV module temperature with a higher accuracy compared with the other mathematical models developed in the past studies. Furthermore, this study showed that the accurate prediction of convection heat transfer coefficient over the PV module based on ambient temperature and wind speed, yields to an accurate prediction of PV module temperature © 2016 American Institute of Chemical Engineers Environ Prog, 36: 277–293, 2017

A Fuzzy-SOM Method for Fraud Detection in Power Distribution Networks with High Penetration of Roof-Top Grid-Connected PV

“…The PV module is a non-linear device that can be considered as a current source as shown in Figure 2 [30][31][32]. Regardless of the internal series resistors, the common current-voltage (I-V) equations of a solar module can be expressed as in Equation 2;…”

Model for Characterization and Optimization of Spectrally Selective Structures to Reduce the Operating Temperature and Improve the Energy Yield of Photovoltaic Modules

“…Many simple models exist to calculate the power or operating temperature of a photovoltaic module, − including those that model outdoor performance. − For example, Sun et al, Li et al, and Vaillon et al modeled the module temperature reduction from a given sub-bandgap reflective and mid-IR emissive coating on the module glass using a 1-D heat transfer equation or a heat balance on the entire module. , Finite-element simulations are also useful for calculating cell temperature or, as in our previous work, ,, module operating temperature and output power.…”

A state of the art review of PV‐Trombe wall system: Design and applications

“…The integration of a PV system is necessary as it replaces conventional building materials and is considered as an energy generator to make the building self‐sustainable . Using PV system diminishes the building's energy demand on conventional grid and overall emission of gases . However, the main problem of solar cells is elevated temperature decreases its efficiency as shown in Figure .…”
