In , the authors indicate that increasing the PV cell temperature by 10 °C results in a 4% energy loss. For this reason, accurate knowledge of the photovoltaic cell temperature is essential for the correct prediction of the energy produced . In the literature, different models have been suggested for predicting PV cell temperature.
Photovoltaic (PV) cell performance is significantly influenced by temperature. Higher temperatures can reduce the efficiency of PV cells, leading to decreased energy output. Understanding and calculating PV cell temperature is crucial for optimizing the design and performance of solar energy systems.
We know the PV modules are usually tested under standard conditions (i.e., standard test conditions (STC) are 1000 W/m 2, AM1.5, 298.15 K), but the actual operating temperature is much higher and there are uncertainties . As one of the core components of PV modules, solar panel performance is strongly influenced by its temperature.
1. Introduction The important role of the operating temperature in relation to the electrical efficiency of a photovoltaic (PV) device, be it a simple module, a PV/thermal collector or a building-integrated photovoltaic (BIPV) array, is well established, as can be seen from the attention it has received by the scientific community.
In this paper, a brief discussion is presented regarding the operating temperature of one-sun commercial grade silicon- based solar cells/modules and its effect upon the electrical performance of photovoltaic installations. Generally, the performance ratio decreases with latitude because of temperature.
In the literature, different models have been suggested for predicting PV cell temperature. The simplest explicit model is the NOCT model, which depends only on ambient temperature and solar radiation . The complexity of the models increases according to the increase in input elements.
