Potencializador de Captação de Raios Solares: Espelhos Móveis para o Redirecionamento da Irradiação Solar Aplicados emMódulos Fotovoltaicos.

Abstract

Despite its advantages and the continuous growth of photovoltaic energy in the market, photovoltaic modules still have low efficiency in the generation of electric energy, which, in fixed module systems, is aggravated by the fact that the solar rays do not fall perpendicularly on the modules, causing their potential not to be used to its fullest. Seeking to solve this problem, optimization strategies have been created to maximize the power generation capacity of these modules. to analyze the efficiency and technical feasibility of implementing mobile mirrors coupled to photovoltaic modules to increase the use of solar rays in photovoltaic generation and reduce the shading effect. For the development of this research, two prototypes were assembled: the first one is a physical model simulating a residence with the system of movable mirrors, automatically controlled, using an Arduino development board, and the second one was built with a kit of photovoltaic modules with a nominal power of 345 W and, coupled to it, a mirror that remains mobile, allowing the rotation and desirable inclination. From the data collected, an average optimization of 19.1% was obtained in the generation and reduction of 31.12% of the shading effect through the redirection of sunlight with the mirror.
