Given that the world’s largest solar farm is located in the scorching hot desert of Rajasthan state, in northeastern India, cleaning the solar panels on the now 5,700-hectare site would be a challenge without solar-powered robotic cleaners.

Ecoppia, a leading company in the field of robotic PV cleaning solutions, uses cloud-based water-free robotic technology to clean the solar panels during the night. It can be controlled remotely using its cloud-based support, and is itself powered by solar energy.

It’s estimated that the robotic cleaners will save more than two billion liters of water over 25 years of a solar plant operation.
