Sizing of a Water Heating System in a Single-Family Residence through Solar Energy Capture: Case Study

One of the major problems faced in the contemporary world is related to adopted energy matrices, since they result in a series of environmental impacts harmful to man. Therefore, it is necessary to develop new technologies for energy generation that can contribute to the preservation of natural resources and, consequently, reduce adverse impacts on the environment. the respective study presents itself as a tool of fundamental social, economic, ecological and environmental importance, since it is directed to the development of a project that aims to use a form of renewable energy to heat water in a single-family residence. The present study aimed to design a water heating system for a single family home, through the capture of solar energy. The methodological process used was the case study addressing the cost benefit of using photovoltaic energy technology to heat water in a single family home. For the dimensioning of the system, a survey of the number of people residing in the building was carried out, as well as the respective water consumption per capita. Based on the above, it is concluded that the project is economically viable since the results demonstrated a significant reduction in the cost of energy consumed at the residence. It presents itself as a tool of fundamental social, economic, ecological and environmental importance as it uses a renewable energy source.
