As commercial and industrial rooftop PV systems continue to expand, module cleaning has become an important part of daily solar O&M. Dust, sand, bird droppings and other deposits can reduce effective irradiance on the module surface, while manual cleaning often involves working-at-height risks, labor coordination challenges and limited cleaning frequency.
For C&I rooftop PV plants, Huibo Robot provides a rooftop solar panel cleaning robot designed for regular dry cleaning on low-slope PV arrays. With a tracked structure, dual roller brushes, automatic recharging, anti-fall sensing and night operation capability, the robot helps make rooftop PV cleaning safer, more regular and easier to manage.

1. Why C&I Rooftop PV Plants Need Automated Cleaning
Compared with utility-scale ground-mounted PV plants, C&I rooftop projects often have tighter space, more concentrated module layouts and stricter safety requirements. Cleaning work may be affected by roof structure, access conditions, working-at-height rules and available maintenance windows.
For rooftop PV owners, EPC companies and O&M service providers, automated cleaning can help reduce reliance on manual high-altitude work and support a more standardized cleaning process. The robot can perform repeated cleaning tasks within a defined operating area, making cleaning frequency easier to plan and manage.
2. How Huibo Rooftop PV Cleaning Robot Works
Huibo rooftop PV cleaning robot is designed around practical C&I rooftop cleaning requirements, including cleaning efficiency, operating safety, battery endurance and routine maintenance.
1. Dry cleaning with dual roller brushes
The robot uses a tracked moving structure and front-and-rear roller brushes. With a brush length of 1000mm and cleaning efficiency of ≥600㎡/h, it supports routine dry cleaning without relying on a water washing system. This makes it suitable for projects that need more frequent module cleaning with reduced water use.
2. Automatic recharging for lower manual intervention
The robot can operate according to the cleaning task and return to the charging position when the battery is low. It is equipped with a 38.4V / 15Ah battery, with a nominal runtime of 3 hours and a charging time of about 2.5 hours.
3. Anti-fall sensing and operation protection
The robot is equipped with front and rear ultrasonic edge anti-fall sensing. It has an IP65 dust and water protection rating and supports operation at night without lighting, helping improve adaptability in rooftop environments.
4. Lightweight tracked structure
With a total weight of about 38kg, the tracked structure helps improve movement stability on PV modules and reduce concentrated pressure during operation.

4. Which Rooftop PV Projects Are Suitable?
The suitability of a rooftop PV cleaning robot should not be evaluated only by plant capacity. It should also be assessed based on module layout, roof structure, module gaps, height differences, deposit type and expected cleaning frequency.
Based on current product compatibility, the following site conditions should be checked first:
1. Module tilt angle ≤10°;
2. Horizontal gap between modules ≤20mm;
3. Height difference between modules ≤30mm.
For C&I rooftop PV projects with regular array layouts, small module height differences and stable cleaning demand, automated PV cleaning can provide strong practical value, especially when the project aims to reduce frequent manual work at height.
If the project has large module gaps, obvious height differences, complex roof structures or special types of deposits, a site assessment is recommended before deployment. This helps confirm robot suitability, operation routes, charging position and cleaning frequency.
5. Service and Technical Support
Huibo Robot can provide equipment commissioning, operation training, remote technical support and after-sales service support to help customers move smoothly from deployment to routine operation.
Support may include product operation training, on-site commissioning guidance, common troubleshooting support, spare parts support and remote OTA upgrades, helping reduce the complexity of daily equipment management.
For different rooftop projects, Huibo Robot can help evaluate the number of robots required, operating areas, charging locations and daily cleaning workflow based on roof drawings, module layout, cleaning scope and O&M requirements.
6. Support for PV Owners, EPCs, O&M Teams and Channel Partners
