The solar panel cleaning
companion
to
count on!

Introducing LOTUS-P4000, a semi-autonomous and waterless solar panel cleaning robot. It is an intelligent, worker-friendly, and economical solution for sharing a single cleaning robot on multiple solar rows. It comes with unmatched product quality and a remarkable ROI under 9 months for typical solar plants. 

Upto 10% more generation output than bi-weekly cleaning

LOTUS P4000 cleaning system is based on ultra-soft microfiber cloths rotating along the length direction of the robot. The microfiber cleaning fins generate airflow and a controlled impact that flicks off the dust particles from the panels without any scratching or dragging.

Precision Engineered

The precision engineered parts provide desired features of high strength and reliable operation while minimising the weight and power loss.

Our robots have passed multiple outdoor and indoor tests of 100 + hours of continuous-operations in IIT Delhi's facilities.

  • The wheels of the robot run on module frame to transfer the load from the frame to the underlying structure.

  • Microfiber cleaning fins flicks-off the dust and debris to prevent any damage to the Anti-Reflective Coating (ARC).

  • Appropriate hardness of the wheel coating material (TPU) provides cushion as well as durability.

  • In-lab simulations result in a Factor-of-Safety (FOS) value of 5.62.
