The use of clean energy from renewable natural resources, replacing what is commonly used is seen as a solution to environment preservation and cost savings with energy generation and distribution. Therefore, the use of solar irradiation for the generation of electric energy is a viable option for regions that present climatic conditions favorable to this technology, as the state of Tocantins does. It is analyzed the feasibility of the energy generation system capable of supplying a building of up to 50m² with monthly consumption of 800kWh using the solar potential of the region. Following the norm that regulates the micro generation of energy in the country, according to the regulatory agency (ANEEL), presenting the components of the system and punctuating the advantages of its implementation. With a survey of energy costs based on the value determined by the concessionaire and the feasibility of deploying solar energy according to the monthly solar irradiation in conjunction with the equipment costs of the system. According to the results obtained from the method of implantation of the system, which is compact and flexible and capable of suiting any existing building structure, which allows a lifespan of close to 25 years, presenting a return on investment in 60 months of operation and providing a 75% reduction in the monthly energy bill, disregarding that this percentage may increase according to possible tariff readjustments. Being a clean energy that causes very low environmental impact in relation to the other methods commonly.
