Solaris Hydrobotics' autonomous PV panel cleaners are made of plastic materials—including the motors—and manufactured using injection technology, a relatively inexpensive process. The robots are also light enough to move on the panels without support rails and only require standard water infrastructure to work.

The patented, water-powered engine used in the Solaris H20 and H40 Hydrobotic™ Cleaners is a proven water-motor technology. Lab tests by PI Berlin have shown that our autonomous robots' cleaning procedure is "very good" and does not harm PV panels within the first 25 years of cleanings at the rate of 3 cleanings per week. In addition, more than 3.5 million motors have been sold in North America and are used in outdoor consumer products.

One Solaris Hydrobotic robot can clean a single line of PV panels up to 100 meters long. A row of panels can consist of a column of 1-3 panels placed lengthwise or side-by-side. A longer row would need to have two robotic cleaners, with the second one cleaning the section from 100 meters to 200 meters.

You can operate the Hydrobotic cleaners using a mobile phone app or via the web. The mobile/web app gives you full control over many parameters, including cleaning frequency, the order in which the rows are cleaned, the number of passes per row, and more.

Yes. The app gives you access to cleaning and power production analytics securely stored on the cloud. You can also monitor the performance of the robotic cleaners in real-time for verifying SLAs and generate KPI reports for robot activities, water usage, "recovered" power production, and more.

Wet cleaning is more effective than dry cleaning because water dissolves the dust and dirt layers containing salts and reduces their adhesion to PV panels. Water also forms a layer between the dirt and the PV panel and reduces the likelihood of scratching. To illustrate how wet cleaning is better, try cleaning your car windshield using only the wipers, and then with both the wipers and the washer fluid.

Solaris H20 and H40 Hydrobotic™ Autonomous Cleaners use 1.5 liters of water per meter of panels. For a row of individual panels placed side-by-side lengthwise, 1.5 liters of water would be used per panel. For a row of double-panel columns or a row of triple-panel columns placed lengthwise, 0.75 liters or 0.5 liter of water be used per panel.

Dry cleaning is the preferred method of cleaning solar panels when wet cleaning is logistically impossible due to infrastructure limitations, or the cost of water is prohibitively expensive. Also, dust can be extremely fine in some climates, and using water will turn the dust into mud that will adhere to the PV panels. In such situations, the Solaris Aerobotic™ Autonomous Cleaners provide extremely cost-effective dry cleaning.

Solaris autonomous cleaners are produced through injection molding and engineered with plastic materials that are highly resistant to harsh environmental conditions. The exterior housing and structural exposed to the environments are made from Polyamide reinforced with glass fibers and treated for UV and hydrolytic stability. Internal parts such as the motor, transmission and operating value, are made from Acetal, PBT, and PBT reinforced with glass fibers.

The water-powered H20 and H40 Hydrobotic™ cleaners are commercially available for delivery in Q1/2021. The air-powered A20 and A40 Aerobotic™ cleaners can be ordered in Q1/2021 for delivery in Q2/2021
