The solarROBOT compact is the ideal solution for small to medium-sized solar installations with inclines of up to 20°. Its agility and efficiency enable the quick and thorough cleaning of large areas, even in challenging conditions.
Not every solar panel system can rely solely on robotic cleaning. That’s why having multiple cleaning options within a solar panel maintenance kit is a smart approach. In some cases, using a hand brush is the more effective solution. This is particularly true for residential installations, smaller or irregularly placed arrays, and south-facing industrial setups where a robot may not function optimally.
For startups and entrepreneurs with a smaller budget, a professional hand brush set can be an excellent way to enter the solar cleaning business. It provides an affordable starting point before transitioning to robotic cleaning for larger surfaces as demand increases.
Additionally, a hand brush set is a valuable complement to a robotic cleaning system. In many cases, manually cleaning certain solar panels while the robot operates in autodrive mode on other sections can enhance efficiency and ensure thorough cleaning across the entire installation.
A hand brush set is a flexible and cost-effective solution, ideal for smaller surfaces or as a supplement to robotic cleaning.
As a cleaning expert, you frequently work with installations that have varying requirements. In such cases, determining the right cleaning method in advance can be challenging. This is where the advantage of a well-thought-out professional cleaning system comes into play. With a customized solution, you always have the necessary tools on hand.
A complete system is tailored to customer needs and consists of multiple components, including hand brushes, hot water preparation, hoses, and cleaning robots. This flexibility allows you to select the ideal equipment for your specific requirements. The hyCLEANER team is here to provide expert guidance, helping you implement the perfect solution.
Conclusion: When it comes to choosing the right solar cleaning system, we firmly believe there is a solution for everyone. Whether hand brushes or cleaning robots, the right equipment ensures you are fully prepared to meet any cleaning challenge.

As a solar cleaning robotics engineer, I’ve seen firsthand how rapidly automation is transforming the maintenance of photovoltaic (PV) systems. Traditional methods—manual labor, water-intensive washing, and time-consuming processes—are no longer sustainable.Solar panel cleaning robots are now revolutionizing how we maintain PV installations. These high-tech devices offer efficient, automated, and water-free cleaning, helping solar systems maintain peak performance even in harsh, dusty environments. Whether you’re running a large solar farm or managing a rooftop array, robotic cleaning solutions are now essential tools for optimizing system output.
A solar panel cleaning robot is a fully automated device designed to clean solar panels without human intervention. Mounted directly on the panel surface, it uses electric motors, intelligent navigation systems, and sometimes AI-powered algorithms to detect and remove dust, debris, and bird droppings.
These robots eliminate the need for water in most cases, making them ideal for arid regions where water conservation is critical. Most are powered by rechargeable batteries and operate silently, ensuring minimal disruption to solar production.
Clean panels are efficient panels. According to the U.S. National Renewable Energy Laboratory (NREL), dirt and dust accumulation can lead to up to 30% energy loss if panels are not properly maintained.In places like Gujarat, India—known for its solar farms and dust-prone environment—this loss can be even more severe, especially during dry seasons. Traditional cleaning methods involve large volumes of water and significant labor costs. Moreover, these methods are not sustainable or scalable.
This is where automated robotic cleaning comes in. With precision cleaning and zero water consumption, robotic systems from companies like Solabot Technologies are now setting new standards in solar maintenance.
Robotic solar cleaners like those developed by Solabot utilize an advanced combination of:Solabot：
Soft, anti-scratch brushes
Sensor arrays to detect debris and panel layout
Autonomous navigation systems to move across rows
AI algorithms for optimized cleaning patterns
Battery-powered motors for quiet and efficient operation
These robots clean without causing micro-scratches, which can otherwise reduce panel efficiency over time. The entire process is automated and can be scheduled during non-peak hours or at night, ensuring maximum energy capture during the day.
Additionally, for large solar farms, these robots come with return-to-dock functionality, automatic recharging, and are designed to move over inter-row gaps using built-in bridge mechanisms.
There are generally two categories of solar cleaning robots available:
???? Semi-Automated Cleaning Robots
These systems involve human-operated vehicles, often tractors, where robotic brushes are attached. The operator controls the speed and brush pressure, ensuring the solar panel surface is not damaged.
Suitable for solar farms with wide spaces and straight rows
Requires turning radius at the end of each row
Brush pressure is manually adjusted, depending on the operator’s skill
???? Fully Automated Cleaning Robots
Fully autonomous robots are permanently installed and move along the panel rows using pre-installed rails or guided tracks.
Best for utility-scale solar farms or commercial arrays
Require charging stations and docking units
Can clean at night or during scheduled intervals
Work independently of human intervention

These systems are more expensive upfront but offer superior ROI over time due to consistent and cost-effective operation.
Absolutely. Here’s why neglecting solar panel cleaning can have serious consequences:
As mentioned earlier, dirty panels can lose 20–30% efficiency. Even light dust can cause a measurable drop in output.
Accumulated grime, bird droppings, or fallen leaves can cause hot spots by blocking sunlight unevenly, leading to thermal stress and eventual cell degradation.
Especially on residential rooftops, unclean panels can look unsightly. They give the impression of neglect and may lower the visual appeal of your building.
From an engineering standpoint, robotic cleaning systems bring several advantages:
Cleaning occurs during non-productive hours (like at night), avoiding interference with solar generation and electrical imbalances caused by panel shading during daytime cleaning.
Reduces or eliminates the need for human workers on rooftops or high places, lowering the risk of accidents.
Most modern systems use dry cleaning methods—bristles, airflow, or static charge—eliminating water consumption and wastewater issues.
Lower operational costs over time, especially for large installations, where labor and water logistics become expensive.
Reduces reliance on diesel-powered water cleaning systems, thereby cutting carbon emissions and supporting ESG goals.
For flat or low-slope rooftops (<25°), self-walking robots are ideal.
For steep roofs, consider semi-automatic systems or professional cleaners.
Ensure maintenance walkways are at least 60 cm wide for robot maneuverability.
Choose a robot that fits the width of your PV rows and can handle obstacles like mounting brackets or junction boxes.
Plan ahead during system installation. Leave room for docking stations, cleaning routes, and consider robot-friendly layouts to avoid shadows or tight spaces.
As a robotic engineer, I always recommend selecting a solar module that aligns with your robot’s power and performance needs:
Robots often run on 12V or 24V battery systems. The selected PV module should match the robot’s:
Open-Circuit Voltage (Voc)
Maximum Power Voltage (Vmpp)
If the system is 24V, use either a high-voltage module or connect multiple 12V modules in series.
Evaluate:
Total wattage draw during cleaning (motors + control system)
Peak current needs
Whether the robot operates off-grid or uses grid backup
Energy storage requirements during cloudy days or winter
Calculate how many modules are needed to recharge during standby periods. If the robot operates multiple cycles per day, you may need larger or higher-efficiency panels.
Choosing the right solar module impacts robot weight, structure, and durability:
Pros: High efficiency, durable, 25-year lifespan, economical
Cons: Heavier, adds weight to mobile robots
Pros: Lightweight, easy to integrate or fold into robot design
Cons: Less durable under extreme UV and heat, generally more expensive
If your robot needs to be compact and lightweight, go for flexible modules. For stationary charging stations, glass modules are often better suited.
The answer is a resounding yes if you’re serious about maximizing solar energy yield, minimizing manual labor, and ensuring long-term system health. Whether you’re managing a 10kW rooftop or a 10MW solar farm, robotic cleaning is no longer optional—it’s the new standard.
