Optimization of a System to Enhance Photovoltaic Module Performance While Producing Thermal Energy
摘要
The use of solar energy in the form of hot air requires the storage of part of the heat produced during hours of sunshine, so that it can be released during hours of consumption, or at least to ensure continuity of operation during cloudy spells. Molten salts, and in particular Heat Transfer Salt, appear to be the best thermal storage fluids. In this paper, we present the design and thermophysical properties of the system's various components. Then, we propose a solution for controlling the temperature of the hot air leaving the collector, in order to broaden its field of application. Finaly, we unveil a mathematical model of the photovoltaic panel, enabling us to determine the current-voltage and power-voltage characteristics using Matlab-Simulink Software.
