STUDY OF THE FEASIBILITY OF INCREASING THE EFFICIENCY OF SOLAR THERMAL COLLECTORS AS A WAY OF DIVERSIFYING THE ENERGY MATRIX THROUGH THE PRODUCTION OF HIGH-EFFICIENCY SELECTIVE SURFACES (Atena Editora)

Abstract

Brazil is currently going through a period of population growth, the increase in the number of new homes and electricity consumption is directly related to this growth. The rate of this increase is greater in the north and northeast regions of the country. In recent years, Brazilians have come across the terms “yellow tariff flag” and “red tariff flag” on the electricity bill, which are fees related to the generation of electrical energy. Climatic factors such as lack of rainfall can also directly affect the cost of energy generation. In Brazil, geographic position and climate are factors that favor energy generation through hydroelectric plants. Recent research by ONS-BR shows that the biggest villain in electricity consumption in a home is the shower, consuming around 25% of energy demand, reaching up to 13% of national demand during peak hours, between 6 pm and 10 pm. However, there are still regions that do not have access to electrical energy, which is replaced by thermal energy generation processes, such as the burning of petroleum derivatives or sugar cane. In the context of seeking solutions to increase energy supply, the viability of using clean renewable energies, which do not emit other pollutants into the environment, is now widely questioned and seen as an alternative to diversify the energy matrix in order to reduce energy consumption. dependence on the rainfall regime, sustain the country's growth and serve areas where energy generation is carried out by burning petroleum derivatives and sugarcane.
