Análise da resposta dinâmica de uma estrutura de placas fotovoltaicas

Abstract

Photovoltaic modules are one of the most widely used technologies providing a renewable energy alternative for electricity generation. Furthermore, these devices have been studied using different approaches to determine their dynamic characteristics. Nevertheless, there’s a void of code of practice guidelines that could allow users and manufacturers to choose or recommend different types of photovoltaic module structures according to the location and operating conditions. To develop an initial approach study of the dynamic response was proposed, experimental and numerical structural analysis using the Finite Element Method (FEM). The study aimed to investigate the dynamic behavior of these structures, focusing on identifying natural vibration frequencies and validating numerical models developed in ANSYS software. Validation was performed through an experimental analysis, using piezoelectric accelerometers to capture vibration data, which were processed with the Fast Fourier Transform (FFT). The experimental and numerical results showed a correlation close to 95%, proving the accuracy and reliability of the computational model employed.
