“…Each subfigure is associated with a specific efficiency model, and inside there are six histograms related to each PV module. The mean and the standard deviation of these error distributions are equivalent to the ones calculated with Equations ( 19), (20), and are presented in Table 7.…”

“…In [20], the efficiency expression (10) was derived from values readily available in PV modules datasheets. By employing simulations, the authors were able to verify that the efficiency values obtained from the proposed model at different temperatures and irradiances had at most 2.6% difference with respect to more complex and validated models such as the Evans efficiency model, e.g.…”

The study of the efficiency of photovoltaic modules in outdoor conditions allows determining their correct operation and to detect abnormal behavior. Most efficiency models developed use experimental data that are difficult to obtain as they require specialized equipment and a long measurement time under laboratory conditions to identify or adjust the model parameters. In this article, we propose a linear equation that estimates the efficiency of photovoltaic modules using irradiance and back panel temperatura measurements as input variables. The main contribution is that the parameters of the proposed model can be obtained directly from the reference information (IEC61853-1 power values) without any data regression. The proposed model was validated using experimental data obtained from three different climatic zones during a whole year. The model shows the best fit to the data of four analyzed models, and its normalized root mean square deviation for all photovoltaic modules is less than 3.6%; this dispersion could be explained by the fact that the outdoor data have an uncertainty of around 3.0%

“…Temperature is the most important parameter which affects the performance of solar cells. In literature, there are many models derived to indicate temperature effect on PV module efficiency [4,[6][7][8][12][13][14]. In literature, the most-cited and the most used efficiency model and open circuit output voltage relation are given below:…”

The use of solar energy systems among renewable energy sources is gaining importance day by day. Photovoltaic systems have a special importance among solar energy systems. Although the incident light flux increases the electrical energy produced in the solar panels, the increase in temperature caused by the radiation reduces the efficiency of the solar panels. Important methods are being studied in order to increase this falling efficiency. Dynamic cooling systems are one of the important methods used in this field. In this study, a dynamic cooling mechanism was designed and developed for a double-faced photovoltaic power generation system. From this point, it was concluded that temperature is one of the important factors affecting the efficiency of solar panels.
