Waterless Robotic Cleaning of Solar Panels

Crisis developing behind the scenes
The water conservation initiative is also important from the point of view that utility scale big capacity solar power plants come up in those areas where water is already scarce. India has an ambitious target of 100 GW of Solar PV Energy generation by 2022 and the water scarcity can hamper this ambitious plan. The sources of water in solar plants can be borewell, water tanker, etc.
As per the study by the renewable energy research firm Bridge to India, the 60% of the water source is borewell in India. The study recorded ‘very high’ water consumption at plants in Rajasthan, UP, Gujarat, Punjab and Haryana, where a quarter of India’s installed capacity is located.
94% of India’s solar capacity is exposed to medium to high level water risk. Rajasthan, for example, is estimated to require 600,000 m³/year for module cleaning. The state is highly arid, and this water use reportedly further exacerbates the situation.
While Karnataka is located in a considerably more humid region than Rajasthan, the higher installation capacity here also requires more water use for cleaning. The 1,000,000 m³/year for module cleaning still places the state at medium to high risk
every problem has a solution
Raising awareness is important, but we decided to go the extra mile and develop a solution to the probem. Atmus Infinity, our flagship product, is an automated robotic solution for water-less cleaning of solar panels.
