Abstract

24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 4357-4359, Photovoltaic (PV) systems used in applications for sustainable mobility dramatically suffer from mismatching effects. In fact, the energy losses due to shadows and soil, but also referable to manufacturing tolerances and ageing, lower the power production of the PV string significantly and make the adoption of such energy source unattractive. It is a common practice, especially if the PV string is made of a small number of cells, to connect the cells in series, thus connecting the resulting string at the input of a battery charger in order to adapt the current profile to the battery needs. Nevertheless, such solutions guarantee a poor battery recharging and this estranges the customer from the PV technology even if it has a large potential in this field of application. In this paper the development of a new PV kit for sailing applications and for sustainable mobility is presented. It has been initially designed for the Class 40 racing craft “Telecom Italia” of Giovanni Soldini, but now it is on the market as a plug-and-play device for a variety of uses.

143. Translation of the Single-Diode PV Model Parameters Identified by Using Explicit Formulas

Author

Abstract

Recent literature proposes some approaches that employ explicit equations for identifying the five parameters of the single-diode model describing a photovoltaic (PV) panel. These methods avoid the iterative solution of a nonlinear system of equations, whose convergence is very sensitive to the guess solution. Therefore, they are particularly suitable to perform parameter identification in real time and to be implemented on low-cost, low-performance processing platforms. In this paper, the applicability of some explicit methods, previously validated under standard test conditions, is analyzed for a large class of panels under operating conditions that are different from the standard ones. The study considers both a consolidated method for translating the PV model parameters as well as a novel approach. The analysis allows assessing the most suitable parameter translation equations for each considered explicit identification method, highlighting the effectiveness of such explicit approaches under different operating conditions. An in-depth validation based on experimental data concerning two commercial PV panels corroborates the analysis.
