Soiling index modeling for photovoltaic systems
| Resumo: | This work has as general objective the creation of a soiling index modeling for photovoltaic systems. The specific objectives are: To characterize the functioning of photovoltaic cells, to simulate the photovoltaic system utilizing the PVSyst software to analyze the production capacity of the system, to identify how these variables affect the production of solar energy and to characterize the conditions of energy production based on simulations. To accomplish these objectives, it is necessary to perform a systematic literature review aiming at the soiling impact and the tilted angle in photovoltaic systems. To perform the modeling, a mathematical formula was adapted to calculate the output current of photovoltaic systems. The differences of this approach regarding the other on the extant literature are the facilities to implement this technology using a reduced number of sensors and demanding less processing power. To validate the proposed soiling index model and achieve the objectives, it was performed a simulation of the photovoltaic system, where the theoretical production values of the photovoltaic system were acquired which were used as a database to analyze the results obtained by modeling the soiling index. From these steps, it was possible to realize the relative error for the modeling varies from 0.33% to 2.48%, with a consistent behavior for most of the scenarios. It is possible to conclude that the behavior presented by the modeling is similar to the simulated. The modeling can contribute to photovoltaic systems as a tool to create better and cleaning schedules. |
