The Impact of Surface Cleaning and Watering on Photovoltaic in Bangka Belitung Islands

The use of photovoltaics as a new renewable energy source is one of the options to increase the energy mix in Indonesia, especially in the Province of the Bangka Belitung Islands. In this regard, research was conducted to increase the efficiency of the photovoltaic used. The treatment is cleaning the surface of the photovoltaic panel and sprinkling water in front and behind the photovoltaic panel. From the measurement results, it was found that the measured voltage before cleaning on the photovoltaic surface was 10.1 - 14.5 Volts and after cleaning the photovoltaic surface increased to 13.4 - 18.3 Volts. The current measured before cleaning the photovoltaic surface is 0.68 - 3.2 Ampere and after cleaning the photovoltaic surface it becomes 2.2 - 8.9 Ampere. Then by treating the water sprinkling in front and behind the photovoltaic simultaneously, the lowest measured voltage is 14.3 Volts and the highest is 18 Volts. For the current measured after watering in front and behind the photovoltaic, the lowest measured current value is 3.2 Ampere and the highest is 9.2 Ampere.
