AirTouch Solar :: Water-Free Robotic Cleaning Solutions for Solar Photovoltaic (PV) Panels

AirTouch Solar is a pioneering company in the renewable energy sector, specializing in advanced, water-free robotic cleaning solutions for solar photovoltaic (PV) panels. Founded with a focus on sustainability and efficiency, AirTouch Solar develops autonomous robots that maximize solar energy output by maintaining panel cleanliness without the environmental drawbacks of traditional water-based methods. Their technology addresses soiling losses—dust, sand, bird droppings, and other debris—that can reduce energy yield by up to 30% in arid or dusty regions. With global deployments exceeding 3 GW, the company serves utility-scale solar farms, helping operators boost ROI through increased production and reduced operational costs.

The flagship product is the AT 4.0 Robot, an advanced linear, water-free cleaning system. It uses innovative wind-blowing technology combined with microfiber elements to remove heavy particles effectively over long distances—up to 2,000 meters on a single charge. The robot operates autonomously along fixed tracks or rails on solar arrays, performing daily or scheduled cleanings with minimal human intervention. It supports various enhanced cleaning modes and has received top ratings from independent testing bodies like PI Berlin for performance and panel safety. The design prioritizes durability, low maintenance, and adaptability to different site layouts, making it suitable for large-scale installations in challenging environments.

AirTouch Solar emphasizes sustainability: their solutions save hundreds of millions of cubic meters of water annually while generating additional clean electricity through consistent panel performance. Robots are engineered for reliability in extreme conditions, with features that optimize cleaning without scratching or damaging sensitive PV surfaces. Clients benefit from data-driven insights, remote monitoring, and integration into plant management systems. The company also provides guidance on “robot-friendly” PV site design to maximize efficiency from the planning stage.

Major projects highlight AirTouch Solar‘s impact, including installations for developers like ReNew Power (450 MWp in Rajasthan, India), Avaada, EDF, and Enlight in Israel and India. Testimonials praise water conservation (e.g., 50 million liters per year at one site), higher energy yields (up to 1.2% or more), and long-term reliability. The technology supports India’s and global pushes for renewable expansion by lowering O&M costs and environmental footprints. AirTouch Solar operates with entities in Israel and India, positioning it strongly in high-growth solar markets.

Beyond hardware, AirTouch Solar offers comprehensive support, from initial site assessment to ongoing service. Their approach combines robotics, AI elements for optimization, and a commitment to innovation in clean energy maintenance. As solar capacity grows worldwide, AirTouch Solar‘s water-free robots play a vital role in making large installations more productive and sustainable. The company continues to expand its reach, delivering proven technology that empowers a cleaner energy future through efficient, automated panel care.
