Análise comparativa da redução da área de geração de energia fotovoltaica proporcionada por módulos bifaciais

Abstract

The wide use of polluting energy sources to supply a growing demand ends up directly impacting the environment.. The sector now has renewable alternatives, such as solar energy. This paper presents a possible solution for power generation in restricted spaces, such as buildings with more than eight floors, where the energy demand is high in relation to the area available for production. A comparative study is presented between used photovoltaic systems and systems with bifacial modules.. The results of this study allow for a real increase in generation efficiency, since the bifacial module uses incident solar radiation as well as solar radiation reflected in the atmosphere to generate a greater amount of energy. Despite their high cost, bifacial modules are used as a viable alternative because they generate up to 30% more energy per square meter compared to the conventional system. In the test case in this work, an option to use bifacial modules represents a 31.9% reduction in the generation area when compared to the area required for the modules used.
