Influence of Dust Removal Mechanism on Solar Power Plant and Its Performance

Sun is a vast source of energy which emits energy in the form of light and heat. Best places to exploit that free, abundant, and environmentally friendly energy are deserts, arid regions, open places and roof tops. But, the main problem with these deserts and open places is dust or dirt. Accumulation of dirt or particles like dust, water, sand and moss on the surface of solar photovoltaic panel obstruct or distract light energy from reaching the solar cells. This is a major problem since the light obstruction materials pose as external resistances that reduce solar photovoltaic performance. We made a microcontroller and voltage sensing integrated system to clean solar panels. Our system is integrated with wiper and provision to add other facilities like water and detergent. The system can work in the night, so there will be no obstruction for the generation of power during the day time. And practically analyzed on 2.2KW plant. Economic analysis with payback period is done. Deploying it ends up being lot of extra power generation, economical and most reliable.
