Fossil resources are limited and their use causes local and global environ-mental damage. This panorama shows us the need for other energy sources, such as photovoltaic solar energy, which can be considered a renewable and practically inexhaustible source. It is in this scenario that this work contributes, carrying out case simulations in a residence in Saquarema with an average annual consumption of 396.33 kWh. Economic feasibility and payback ana-lyzes will be carried out. A numerical analysis of the environmental impact will also be carried out, addressing the emission of the solar system, as well as a descriptive approach on the environmental impacts in the panel manufactur-ing process and in the manufacture of some components. These analyzes are elaborated from equations and data obtained from other works to arrive at a final result and with the household electricity bill data. A technical analysis of sizing and energy efficiency analysis of the system. An exergy analysis will also be covered in this article. As a result of the study for the main case with a rate of return of 2.5 percent and efficiency factor of 0.80, a reduction of 31 percent in the amount of CO2 equivalent was observed when compared to the use of the network, in the energy part an efficiency of 12 percent which is close to the 15 percent provided by the manufacturer and an exergetic efficiency of 18 percent. Economi-cally the NPV was positive and with time and payback of 6 years. With the sensitivity analysis the biggest changes were in the economic part, and with regard to exergy, energy and environmental impacts, we obtained results with low variation.
