ABSTRACT
In this study, energy generation of a solar panel in case of different surface contaminants is experimentally examined. The energy production of a solar cell is significantly influenced by the contamination of the panel’s surface. Not only objects in the environment, but pollutants on the panel’s surface also can create shadow effect. The energy production and the efficiency of a solar panel is experimentally investigated in case of different types of contamination, such as leaves, dust and simulated bird excrements. Measurements are done in case of different polluted areas and amount of pollution. A connection between the power generation and the contamination is observed. Following the observation, it is possible to determine the loss of energy production, caused by the surface contaminants, while the optimal cleaning period can be determined.
