Efficiency improvement of solar array by mitigating soil loss using Arduino

Installation of photovoltaic cell has been increasing day by day in industries and houses due to the increase in cost of power. But the major concern for the increase in future usage of the photovoltaic cell depends on the improvement in efficiency. Accumulation of soil and debris in the photo voltaic cell from the environment reduces the efficiency at the considerable level. In this paper, increase in efficiency can be achieved by removing the soil and dust accumulated in the surface of the photovoltaic cell using wiper which has been operated with servomotor, governed by Arduino microcontroller.
