Estudo da viabilidade de aproveitamento da energia solar em cidades da América do Sul através da aplicação do método da fração solar

Abstract

This paper presents a study on the feasibility of using solar energy in six different cities of South America (Buenos Aires, Caracas, Lima, Montevideo, Rio de Janeiro and Quito) in the supply of energy demands for heating domestic water in a residence. In order to do so, a quantitative analysis of the monthly solar irradiance that can be absorbed by solar collectors is carried out in these six cities. Then, the solar fraction method is applied with the purpose of to know which part of the thermal loads of hot sanitary water in the residence can be supplied by the solar collector that compose the heating system. By searching and comparing the results found, it was observed that for all cities, solar energy showed a high participation in the supply of thermal loads, proving to be a great alternative for heating sanitary waters.
