Projeto e implementação de planta fotovoltaica de 65 kWp

Abstract

The present work aims to present the activities carried out during the design and implementation stages of a 65 kWp photovoltaic system located in a coastal region of northeastern Brazil. In the design phase, the calculations made to design the system and the criteria used to choose its components are explained. It was chosen 325 Wp Canadian Solar panels and an ABB inverter with 50 kW of nominal power. A topographic survey was performed with unmanned aerial vehicle to study site shadowing. This study was elaborated with the PV*Sol simulation software, which resulted in obtaining parameters such as capacity factor (FC) and generation forecast. The results were 19.92% of CF and a production of 113,429.5 kWh/year was predicted. In the implementation phase, all the procedures performed for the installation of the system are described. These were divided into stages in order to illustrate in a chronological order the work performed. Finally, it is made the general analysis of the approximate costs and deadlines related to the realization of the project, besides praising positive points and punctuating improvements in the activities. The final costs exceeded 14.96% of the previously estimated R$ 285,000.00. This increase was due to logistical difficulties and expenses with works of security infrastructure. The deployment was successfully completed after 4 months and 20 days from the start of the project.
