Análise técnica e econômica para implantação de um sistema fotovoltaico residencial

Abstract

Searching an alternative solution for electric energy production, this work has the technical and economic feasibility analysis for the implementation of a residential photovoltaic system connected to the grid. From the dimensioning of the photovoltaic panels and inverter, considering the effects of temperature on the efficiency of panels and obtaining budgets with companies of the region to obtain the average value to obtain the other components of the system, as well as their installation and homologation, verifying the costs related to this deployment and the return of this investment by calculating the project payback. After this stage a budget was made with a company specialized in photovoltaic systems to verify if the selected system was consistent with what would be indicated by the company, and the result was very approximate. Finally, a financial analysis is carried out based on comparative analysis with another type of investment, the latter being a savings account. From the results, it was verified the feasibility of the implantation of the photovoltaic system, which was more profitable than the investment in savings account for the considerations adopted.
