Desenvolvimento de produto: melhoria da eficiência energética em painéis fotovoltaicos através da aplicação de um sistema passivo de troca de calor

Abstract

Energy consumption in the world has grown dramatically and with it the concern and the search for alternative energy generation solutions that can have less environmental impact in its process. There is also greater interest in energy efficiency solutions both in the production and design of new products and those already in use in the market. The growth of economic activities has contributed to the increase in energy use, including in Brazil, where the percentage reached 73% between 2000 and 2017, according to data from the Energy Efficiency report of 2018. Brazil stands out as a of the least carbon intensive economies in the world due to their characteristic of electric generation given by its its great extentand the extremely favorable climatic characteristics. Even so, it is known that today there is a great variety of potential on the market that can and should be better exploited, it is the generation of energy from clean sources, which stand out here the wind and solar. The main objective of this research is the development of a heat exchanger capable of improving the efficiency in photovoltaic panels by reducing the operating temperature. By reviewing the literature on research-related topics and concepts such as solar energy, energy efficiency, clean energy, photovoltaic panels and others, it was found that the panel can lose up to 20% of its energy efficiency when subjected to high temperatures. job. In this way, with the aid of the Solid Works 3D CAD software, some models of heatsinks obtained through aluminum frame were built and tested, which can be easily found in the market for the temperature exchanger test and elaboration phases. The research is structured in the development methodology known as Design Science Research (DSR) and as a result will be presented a profile model different from those available in the market, but which presents better results in heat dissipation, based on decision making. the results obtained through simulations performed with the known frame.
