In the market it is possible to find different technologies of photovoltaic modules, these technologies experience different impacts related to performance due to dirt in modules. This dirt, besides being able to degrade the modules, causes a loss of performance of the generated power. Studies comparing the loss of dirt in the various types of photovoltaic modules are scarce, and when found they are performed in the laboratory. The present study seeks to evaluate the loss of performance in the system caused by the accumulation of dirt on the surface of the modules, using IxV curves measured directly on modules of a photovoltaic plant. An experimental explanatory research was carried out, seeking to correlate, the ideal time for cleaning photovoltaic modules of different technologies, aiming at the maximum efficiency of the system. For the evaluation of the research, the strings of the power plant were cleaned in different time intervals, seeking to prove which time interval is more appropriate, this makes it possible to measure different values of maximum power imposed by the amount of dirt deposited in the modules, and the comparison of values obtained in strings of different characteristics. The power plant used by the research is located in Capivari de Baixo, Santa Catarina State, in the Parque Ambiental Encantos do Sul, managed by the company Associação Jorge Lacerda, the purpose of the power plant is to make the park self-sufficient energetically, so that a study that improves the efficiency and fits the cleaning mode is of great help to the company and its goal. In view of the fact that soiling implies a loss of efficiency of photovoltaic modules, this research has analyzed different cleaning times and a study to find out what is the ideal time interval for cleaning, in order to maintain the system with high efficiency of the photovoltaic modules studied.
