Abstract
To keep high-performance operations in photovoltaic system is an important task. However, solar panels are subject to pollution in the natural environment. Possible pollutions include dust in the air, feces in birds and dust from burning materials, etc., which can cause solar energy performance reduced. In this paper, the effects by manual cleaning and natural cleaning are investigated and the result is aimed to help manager to determine the timing of cleaning. The Array Ratio (RA) was used to evaluate the daily power generation performance and various conditions which can prevent from obtaining reliable RA values were addressed. Experiments were conducted to verify the proposed approach. The results showed that the first manual cleaning has a significant cleaning effect of 10.11% and the second manual cleaning effect only 2.03% since before the cleaning there were several heavy rains, resulting in natural cleaning of the plant.
