About The Initiative

About The Initiative

ReNew has identified water conservation as a critical area of focus in its sustainability efforts. One of the primary operational activities in the company's photovoltaic (PV) plants is module cleaning, which traditionally involves the use of water. ReNew has started using waterless robotic cleaning for its PV modules to address this challenge.

Outcome

The waterless robotic cleaning approach has offered several benefits to ReNew. Firstly, it eliminated the need for water, leading to significant water savings. Secondly, robotic cleaning was faster and more efficient than traditional cleaning methods, resulting in increased uptime of the PV plants. Thirdly, it reduced the risk of damage to the modules, which could occur with manual cleaning methods.


ReNew deployed the waterless robotic cleaning approach across select solar plants and has been able to save 216,533 kiloliters of water in 2021-22 which is approximately 200 times compared to 2020-21. Additionally, the waterless cleaning approach reduced the cleaning time by half, which led to increased uptime of the PV plants and higher energy yields.
