Automated Solar Array Cleaning System by using Robot

In present days the energy consumption scenario is clearly showing the faster depletion of fossil fuel reserves. On the other hand, the energy usage index indicates the state of growth of a country. The use of renewable energy sources like solar PV has increased in recent years. It faces lots of challenges such as high cost, erratic and unpredictable in nature, needs for storage and low efficiency. The solar PV modules are generally employed in dusty environments which is a case like India. The dust gets accumulated on the front surface of the module and blocks the incident light from the sun. It reduces the power generation capacity of the module. The power output reduces as much as by 50%. The solar photovoltaic panel cleaning technology can considerably increase the efficiency of electricity generated and also increase the durability of Solar panels. Power output is reduced if the module is not cleaned for a month. In order to regularly clean the dust, an automatic cleaning system that removes the dust on the solar panel is to be developed. To overcome this, a solar panel cleaning robot is used to clean the PV modules.
