The use of electric energy in Brazil is provided in mostly through hydroelectric. With the increase of energy demand and the growing precariousness of the natural resources explored, related to an environmental amplitude, is necessary to investigate solutions with renewable energy. The solar irradiation is one of the most important and plentiful renewable energy sources and one of the options to replace the hydroelectric. In this context, the study of the environment impacts related to your deployment becomes relevant to ensure a clean and sustainable system. Thus, the study aims to characterize the potential environmental impacts caused by the production of a thermal solar panel, produced in the city of Pato Branco - PR, composed of polymeric material, intended for residential use and capable of heating 62.5 liters of water at 60ºC during the local solar cycle, associated with the life cycle, identifying the impact categories with the most significant contribution in this system. From this objective, a study was developed on the production process of solar panels, manufactured by the company Sustentabil Energias LTDA in Pato Branco, PR, verifying the contribution of each of the processes and inputs, as a result of environmental impacts. For this determination will be use the Life Cycle Assessment (LCA) technique, through Simapro® software that uses the ecoinvent® database, which evaluates the inputs and outputs of the entire system, in this case considering the product's production process (cradle to gate), checking which component has the greatest impact and which category it fits into The CML methodology was used. The results found indicate that the flux with the most significant potential environmental impact, that is, with the greatest impact, is the polycarbonate module. This result reinforces the bibliography that the main component of the solar plate, regardless of whether it is a thermal solar plate made of conventional or alternative material is the most impactful, a fact that does not make its use unfeasible.
