The graduation project shows the results of an analysis of the technical, financial and environmental feasibility of a photovoltaic solar system connected to network (SFCR) in Granja La Fortaleza located in Melgar - Tolima, based on the historic energy demand of the Farm, availability of solar resources, the technological features of the system and the actual costs for the use of photovoltaic solar energy. Financial analysis was performed and the environmental benefits of replacing the current energy supply by solar energy were evaluated. It is concluded that the installation of solar photovoltaic system is feasible for weather conditions diagnosed as solar radiation, temperature and precipitation of the place and the required technical conditions. According to the results of the financial analysis, the cost of electricity savings is not enough to recoup the investment.
