Estudo de caso de desempenho: duas usinas fotovoltaicas

Abstract

This study aims to analyze the performance, generation, consumption, and economic data of two off-grid photovoltaic plants of different sizes located in the state of Goiás. The research, conducted in partnership with the company Yellot, used data collected between January 2022 and December 2023. The study also includes a sustainability assessment, considering the amount of carbon avoided and the number of trees needed to offset emissions if conventional energy were used. The results show that, after adjustments made in September 2024, Plant I exceeded expectations, generating 104% of the projected energy, while the average monthly generation in 2022 and 2023 was 97%. However, the energy consumption of Plant 1 reached 178% of the projected value, indicating high demand. Plant II, after improvements, generated 91.35% of the projected energy, with an average of 89% in the previous years. Its energy consumption was 148.2% of the initial projection. These results highlight the benefits of the interventions made, but also emphasize the need to monitor the increase in consumption at both plants
