“…In order to describe the geometry of the considered LCPV system there have been denoted the following quantities (see Figure 11) [20,21]: -x is the angle between the mirror and the photovoltaic module, and is a constant parameter; -h is the maximum incidence angle created by the solar ray with the normal to the photovoltaic arrays; -k represents the ratio between the mirrors width (Lm) and the photovoltaic module width (Lp); -c1, c2 are the width coefficients of PV module brushed by the rays reflected by the mirror; -kl is the longitudinal deviation coefficient, defined as the ratio between the additional length of the mirror (necessary for the compensation of the deviation of solar rays reflected, caused by the elevation deviations of the PV module from the solar elevation) and the photovoltaic module width.…”

Solar irradiation is one of the important parameters that should be taken into consideration for the design and utilization of a photovoltaic system. Usually, the input parameters of a photovoltaic system are solar irradiation, the ambient environment temperature and the wind speed, and as a consequence most photovoltaic systems are equipped with sensors for measuring these parameters. This paper presents several mathematical models for solar irradiation assessment. The starting point is represented by the mathematical model of extraterrestrial irradiation, and resulting finally in the model for solar irradiation, absorbed by a low concentration photovoltaic panel. These estimating models of solar irradiation have been particularized for the Craiova, Romania, and have been verified through numerical simulation. Regarding terrestrial solar irradiation, four mathematical models have been adopted, namely Adnot, Haurwitz, Kasten and Empirical (EIM). Of these, the most appropriate for the Craiova location were the models Adnot and Empirical. Consequently, for the calculation of the solar irradiation absorbed by the photovoltaic (PV) panels with low concentration, these models have been taken into consideration. In this study, a comparative analysis was also carried out with respect to the solar irradiation absorbed by the PV panels without concentration and those with collectedness of the solar radiation. This analysis was based on the results of numerical simulation and experimental tests. OPEN ACCESSSustainability 2015, 7 2645

“…The solar constant is generally used for photovoltaic calculations, but the actual value of the solar intensity falling on the surface of the Earth's atmosphere is variable during the year, since the trajectory of the Earth's orbit around the Sun is an ellipse. The elliptical trajectory causes the value of the actual radiation intensity to vary in the range of 3.4% of the solar constant, while it reaches its maximum in January, and the value can be expressed using (3). Based on this equation, we can calculate the value of the incident radiation intensity on the upper layer of the atmosphere for a given day of the year n [34,35].…”

This paper presents a proposal of a complex mechatronic system that enhances the effectivity of obtaining energy from renewable resources. The main focus is on the photovoltaic energy system, which obtains electricity from the conversion of solar radiation through photovoltaic crystalline silicon-based panels. The design of the complex mechatronic system consists of several steps. The structural design of the photovoltaic panel positioning unit in the form of a three-dimensional model is made in the selected modelling programming environment. Subsequently, a propulsion system is proposed for the designed structure, the functionality of which is verified in the programming environment Automated Dynamic Analysis of Mechanical Systems. The control system design using a programmable logical controller is also presented. The corresponding control algorithm is designed in the programming environment Step7 and covers the optimal positioning of photovoltaic panels. The developed application in the WinCC environment provides a visualization of the positioning control process. The conclusion is devoted to the assessment of the obtained results for the proposed complex mechatronic system for photovoltaic panel positioning in comparison with photovoltaic panels in fixed installation. The presented results were obtained by simulations.
