“…The minimum value of I sc in the worst winter months is approximately 12% less than the peak value of this parameter for the a-Si/μc-Si solar cells. This reduction is very small compared to the observed on a-Si PV modules in outdoor conditions of work at the same location [Kichou et al, 2016]. The reduction of R sh in TF solar cells under outdoor exposure for long periods of time has been previously reported [Radue and van Dyk, 2010;van Dyk and Meyer, 2004].…”

“…The parameter extraction technique used in this study is the same used in [Kichou et al, 2016], where the monitored data: Current, Voltage and Power at the DC output of the PV array together with the in-plane irradiance (G) and cell temperature (T c ) profiles, are used as inputs for the parameter extraction algorithm in order to estimate the set of model parameters of the solar cells forming the PV array.…”

“…2-5 and actual daily profiles of monitored electrical parametersnamely, current and voltage at the DC output of the PV array, together with G and Tc. Then, a nonlinear regression algorithm based on the LevenbergMarquardt method was applied to both data sets: The daily monitored data from the PV array in real conditions of work and simulation results generated by using the described model, in order to minimize the following quadratic function [Chouder and Silvestre, 2009;Durisch and Mayor, 2003;Kichou et al, 2016]:…”

The analysis of the degradation of tandem amorphous silicon (a-Si:H) and microcrystalline silicon ( -Si:H): Micromorph thin-film photovoltaic (TFPV) modules and its impact on the output power of a PV array under outdoor long term exposure located in Jaén (Spain) is addressed in this work. Furthermore, the evolution of main solar cell model parameters is evaluated by means of parameters extraction techniques from monitored data of the PV system in real operation of work. The degradation rate and the stabilization period of micromorph TFPV modules, as well as the results of the evolution of each of the solar cell model parameters along the outdoor long-term exposure are analysed in order to gain a better understanding of changes in performance of micromorph TFPV modules and the behaviour of the output power of the PV generator.

“…Thin-film PV modules have higher degradation rates than polycrystalline or crystalline silicon modules. Their behavior and degradation patterns in Jaen, Spain, a dry and sunny inland site with a continental-Mediterranean climate, were analyzed by Kichou et al [4] from July 2011 to October 2014. They used the least squares method and linear regression.…”

Investigation of Operating Parameters and Degradation of Photovoltaic Panels in a Photovoltaic Power Plant

Recently, the use of photovoltaic (PV) cells and the increase in the number of photovoltaic power plants has led to a detailed examination of their operating parameters. In this article, we discuss material and operating parameter influences on the performance and efficiency of photovoltaic panels in a photovoltaic power plant. The plant consisted of 3600 pieces of polycrystalline PV panels from Renewable Energy Corporation (REC) Solar (type REC 230AE) with a maximum power of 230 Wp. Parameter measurements were made three years after the power plant was started. The measured and computed data were statistically processed using multidimensional statistical methods where the relationships between input and output variables were examined, which was subsequently quantified by regression analysis. Using the ANOVA, the variability of the measured efficiency of the panels and the performance for individual years was examined. Efficiency has been found to increase significantly over the years. The reason for this is the statistically proven prevailing operating time of the PV power plant in conditions with lower temperature than standard operating conditions (25 °C). Ageing was not confirmed in optimal conditions and calculated efficiency was constant.

“…The use of meteorological data will be used in order to analyse the behaviour of the photovoltaic devices before and afterwards its installation. This data will be used before the installation is sited, if the behaviour of the systems in particular conditions is simulated [18], otherwise the data will be used afterwards if some aspects are approached, such as the degradation suffered by the photovoltaic devices with the passing of time [19], or the behaviour of different technologies in different meteorological conditions [20][21][22].…”

Abstract:Renewable energies have experienced a great growth in recent years, and nowadays participate in the set of energies used in developed and developing countries to produce electricity. Among these technologies, photovoltaic energy, which produces clean electricity from the Sun, is the one that has grown faster, and its implementation all over the world is a guarantee of a solid and efficient energy technology. Nevertheless, in order to design very efficient solar energy systems, it is crucial to have a good solar radiation database. There are databases where it is possible to find information on solar radiation, but only for horizontal surfaces. Afterwards, it is necessary to transform the horizontal solar radiation data to tilt solar radiation data. This transformation is not easy, and the application of complex mathematical equations, and expressions, and difficult algorithms must be done. An application called virtual laboratory "OrientSol 3.0" which allows the user to easily obtain the solar radiation for any tilt surface has been developed by us. Thus, our main objectives in this paper are to present the developed virtual laboratory and to explain its main features and core functionalities. In order to point out the difficulties and complexity of the transformation of horizontal solar radiation data to tilt solar radiation data, we will present some examples of the results this application provides and compare the solar radiation data supplied with this application with some other solar radiation data obtained from other databases.
