Estudo de geração e análise detalhada de perdas de um sistema fotovoltaico em Fortaleza/CE

Abstract

This work shows a study of energy generation losses presents in a photovoltaic solar system, in a depth way of each type of loss, in a way that is not usually seen in other works in the area. Considering that when this type of system is bought, designed and installed, both the owner of the equipment and the technical team share the interest to extract the maximum system performance. Initially, the work introduces and explains important concepts for its development, explaining the operation of a solar plant and the role of each equipment present in it, besides punctuating the types of losses and its reasons. The concepts introduced enables the proposed case study of a power plant with maximum power of 38.94 kWp, 1 inverter and 66 solar panels, installed on a store located in Fortaleza/CE. In this case study all the necessary premises and all the losses present in the system are punctuated and analyzed separately, with support of the PVsyst software, which is made a simulation of the system with all its losses. As a result, the loss diagram is extracted, that shows the impact of 36.24% for all losses for the solar plant in the first year of operation. With this simulation it’s possible to make a comparison between the expected power generation and the real power generation with the solar plant working. Finally, some analyzes are performed, one about the financial impact that these losses cause, revealing an impact of around 25,699.37 BRL, other about the possible solutions to minimize each type of loss and maximize efficiency of the photovoltaic system and a couple simulations of possible scenarios with application of proposed solutions, one with the use of microinverters and other with with the change of the plant location to a location without shading.
