Manual cleaning in solar parks or rooftop installations is often not feasible, due to its scale, so you will need to use some help. A big share of solar assets owners or maintenance teams use robots to optimize the cleaning of photovoltaic solar panels.

It is the most versatile cleaning method regarding the scale of the installations and its use is raising as fast as the Solar Industry.

Each robot has its advantages and limitations, so you need to make sure that you choose the right robot for your needs. Before buying, do your research and talk with others that already use them. Most solar cleaning companies are really approachable and will share with you their experience.

Based on our experience and of our partners, you can check our top 5 recommendations (in no particular order) for PV solar panel cleaning robots.  Let’s check what their manufacturers say about them.

hyCLEANER solarROBOT

The hyCLEANER solarROBOT Pro stands out for its ability to handle large photovoltaic installations with speed and efficiency. Designed for both rooftop arrays and ground-mounted systems starting from 2,000 m², this model focuses on delivering quick, economical, and environmentally friendly cleaning.

Its modular construction allows the robot to be assembled in just a few simple steps without the need for tools, making setup fast and convenient. Once in operation, the solarROBOT pro is controlled remotely via radio control, keeping the operator at a safe distance. Features like Autodrive simplify the cleaning process by allowing the robot to navigate across panels autonomously, while edge detection and fall-protection sensors ensure maximum safety by automatically stopping the machine at panel boundaries.

A key advantage of this model is its chemical-free cleaning: thanks to its innovative brush design, the robot removes dirt effectively without requiring detergents or additives. This not only protects the panels but also supports sustainable maintenance practices.

Sunbotics Sunbrush

The Sunbotics 4-in-1 cleaning system, a cross-product modular system and individual extensions. Different sized robot manages different levels of inclination.

The most important parts of the Sunbotics series are the motorized quick coupling System and the intelligent carrier arms. Every Sunbotics product is based on these two features. When purchasing a Sunbotics machine, most of the other products are always included and your product will be expanded in just a few simple steps.

Easy to handle you can carry your equipment comfortably onto the roof – without the need for a lifting platform. Disassemble your equipment conveniently and quickly on the ground and reassemble the individual parts on the roof. Sunbotics carrier arms have a high strength aluminium core, having a lower overall weight.

Mains Specifications:

• The suspension system is equipped with a remote control of about 100m range.
• Clean on up to 25° with a 1,45 m brush size, the larger versions with a 2,10m or 3,20m brush size can drive on up to 20°.
• Power & battery operated - the sunbotics e-Boxes are available in different versions, all operated either via power connection or rechargeable battery.
• Overcoming obstacles - Overcomes module gaps of up to approx. 60 cm. Height-adjustable brushes that allow to easily overcome slight height differences of up to approx. 15 cm.
• Anti-splash - The robust splash guard is made of truck tarpaulins.
• Integrated water tanks.
• The shifted brushes that ensure that best possible cleaning results.
• The specially designed rubber profiles of the chains easily provide extra grip for vertical driving on inclinations of up to 25°.

SolarCleano M1

The SolarCleano M1 is an ultra-lightweight and highly versatile mini solar robot designed for smaller installations, rooftop systems, and even window cleaning. Its compact design and powerful cleaning capability make it ideal for operators who need agility without sacrificing performance. It is small, easy to handle, and delivers impressive efficiency—1 robot ≃ 1 MW cleaned in one day by one operator. Suitable for both wet and dry cleaning, the M1 adapts perfectly to smaller or more complex sites.

Why trust the SolarCleano M1? The M1 is certified NO microcracks after electroluminescent testing and connects to standard garden hoses (13–15 mm; 2.0–8.0 bar). Water consumption can be regulated via valves. Its helicoidal 0.8 m brushes with two bristle types ensure efficient cleaning for various panel types, including thin-film.

Highly mobile and fully modular, the robot can be dismounted into 3 parts and assembled in just 2 minutes. At only 37 kg, it can be easily transported in any vehicle and operated by a single person.
