Eficiência na geração de energia elétrica de painéis fotovoltaicos em diferentes processos de manutenção

Abstract

The elevated levels of atmospheric pollutants mostly produced with the use of non renewable resources of energy has motivated the country to search diversification in the energetic matrix. Furthermore, the current standards of energy production are structured in the use of non renewable energy, especially the nuclear energy and the fossil fuels. In addition, these energy sources result in elevated impact in the local environment. In the face of the current situation, the photovoltaic panels perform as a promising and effective alternative that is able to show the use of an abundant and endless source. Although, the dirt accumulation in the units surface results the loss of efficiency in the energy generation. Therefore, in this assignment was analysed the photovoltaic panels efficiency in the electric energy generation, considering three different maintenance systems of the photovoltaic panels. In the first treatment (T1) happened manual cleaning of the panels, with non pressurized water application and using neutral detergent. In the second treatment (T2) were made manual cleaning through non pressurized water drain, simulating a water sprinkler during 60 seconds. Lastly, in the third treatment (T3), weren't made interventions in the panels. Accordingly, it was collected the production data and realized the efficiency evaluation and the economic viability of each maintenance system. Based on the results, it was possibly to verify that related with the efficiency, the first treatment had the biggest energy generation. However, the third treatment demonstrated the best economic option.
