ESTUDO DA GERAÇÃO DE ENERGIA ELÉTRICA ATRAVÉS DE UM PROTÓTIPO DE TELHA FOTOVOLTAICA DE PET

Abstract

The transition for a low carbon economic matrix demands the development of efficient and clean solutions. In this context, the use of photovoltaic distributed systems is growing because of public policies, scientific and technological development. A new construction concept called Building Integrated Photovoltaic Systems (BIPV) considers the introduction of photovoltaics elements in the functional or architectural structures. Among the various promising solutions in BIPV, photovoltaic roof has conceptual advantages such as: easy installation and less visual pollution. Despite the advantages, there are many aspects that need to be studied, since the photovoltaic modules efficiency depends on the received solar irradiation and operating temperature. Some open points related to photovoltaic roofs are: type of module material, that can be crystalline (monocrystalline or polycrystalline), inorganic thin films or organic technologies; incidence angle of solar irradiation, which are influenced by position and inclination of the roof; presence of atmospheric particles or gases, which can cause energy mirroring; capacity to dissipate heat, since it is not foreseen the introduction of the elements in the roof; certification of products, since the technology considers the possibility of connection to the public energy grid that has some control parameters; among others. To contribute with the development of photovoltaic roofs, this paper shows the results of experiments carried out in a prototype that combine PET roof and polycrystalline modules. Thus, the objective of this work is to study the behavior of electric power generation in a photovoltaic roof considering the climatic characteristics of the Parati city.
