The solar panel cleaning
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.
Cleaning via airflow + flicking action
Up to 2 years of microfiber fins life
Easy microfiber replacement
Up to 98% cleaning in a single pass
Our attention to detail and support from IIT Delhi has resulted in a precision-engineered machine that delivers performance while consuming less power.
We have patented our unique dual-drive system with real-time orientation control which helps to overcome the module irregularities upto 40 mm.
This aluminum and steel-made drive-unit is custom-designed to be strong and lightweight.
High-grade aluminum & stainless steel is used in parts and fasteners to achieve exceptional durability and corrosion-resistant product.
High-performance BLDC motors provide 5000+ hours of life under extreme conditions with high power to weight ratio and zero maintenance.
Our robots have a rigid open-body frame which doesn’t slack while lifting and produce minimal shading with stable operation under 50 kmph wind.
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.
Easy to handle and move
Carefully designed detatch-able handles provide row-shifting time as low as 25 secs while minimizing the weight of the robot.
25 secs row-shifting time
Maintains the SAFETY and INTEGRITY of solar PV module
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.
