Modelo de estimativa da potência elétrica gerada por um sistema agrofotovoltaico

Abstract

This study aimed to evaluate the feasibility of using solar irradiance and air temperature data from an external agrometeorological station as an alternative to on-site monitoring for estimating energy generation in agrophotovoltaic (APV) systems, with the goal of optimizing implementation costs. The methodology consisted of a comparative analysis conducted between October 2022 and May 2023, where the actual generation of a module was compared against two estimates: one scenario using data measured directly in the APV system's microclimate and another with data from the external agrometeorological station, applying the necessary tilt and orientation corrections. The results showed that although the total estimated production with local data was slightly higher (384.89 kWh versus 378.24 kWh), the daily validation confirmed the high accuracy of the model using data from the station, showing minimal variations compared to the measured values, such as the one recorded on April 12, 2023 (2.17 kWh measured vs. 2.15 kWh estimated). Therefore, it is concluded that data from nearby agrometeorological stations, when properly corrected, constitute a robust and sufficient source of information, validating their use as an economically viable alternative for future projects.
