Project Background
A 5.6MW distributed solar power station on a commercial and industrial rooftop in Hebei Province, built in 2019, had long-term accumulation of pollutants such as dust and catkins on the rooftop panels, seriously affecting power generation efficiency. The station had previously tried cleaning methods such as manual wiping and high-pressure water jets, but these methods resulted in uneven cleaning, high water consumption, and the risk of hidden cracks in the panels. In early 2024, the station introduced the XYTX2 manual water spray brush solar panel cleaning machine, seeking a safer, more efficient, and more water-efficient cleaning solution.
Application Process
Equipment Configuration:
The power station is equipped with two XYTX2 manual water spray brushes. These devices feature a user-friendly, retractable pole design to accommodate modules of varying heights. Equipped with a highly efficient, water-saving nozzle and soft, durable nylon bristles, they can be directly connected to an on-site water source for manual cleaning.
On-site Operation:
No specialized training is required; operators can learn and use them immediately. A single operator can operate the brush by simply gripping the brush handle, connecting the water line, opening the valve, and gently moving the brush head along the module surface. The spraying and scrubbing process occurs simultaneously, removing dirt and rinsing instantly, leaving no residual water stains. Cleaning a single module takes approximately 30 seconds, and approximately 1MW of cleaning capacity can be completed in an eight-hour workday, achieving approximately three times the efficiency of traditional manual scrubbing.
Effect comparison:
Cleanliness: Soft brushing combined with water flow provides thorough cleaning, eliminating the risk of scratching the module surface and significantly improving light transmittance.
Power Gain: The day after cleaning, power generation increased by approximately 11.5%.
Water Savings: Compared to traditional high-pressure water guns, this system saves up to 60% water and requires low water pressure, sufficient with standard mains pressure.
Safety: This completely physical cleaning method eliminates electrical risks, making it ideal for rooftop power plants.
User feedback
“This brush has really solved a big problem for us!” said Master Li, a maintenance worker at the power station. “What used to take two people a day can now be completed by one person in half a day, and it’s not tiring at all. By adjusting the water flow to a lower level, the roof won’t be completely flooded. It’s safe and clean. Most importantly, we no longer have to worry about damaging components.”
Technical highlights verification
Flexible and Efficient: The telescopic pole design accommodates diverse scenarios, and the brush head flexibly rotates, easily reaching even tight corners and edges.
Economical and Durable: No electricity required, minimal failure rate, and near-zero maintenance costs; bristle replacement is inexpensive.
Safety Guaranteed: Manual operation fundamentally eliminates electrical hazards and potential damage to components from high-voltage shocks.
The successful implementation of the XYTX2 manual water spray brush photovoltaic cleaning machine at this rooftop power station demonstrates its effectiveness as a truly labor-saving, water-saving, worry-free, and cost-effective solar panel cleaning tool. It is particularly well-suited for the regular cleaning and maintenance of distributed rooftop power stations, effectively improving power generation efficiency and reducing O&M costs, making it a trusted “right-hand man” for solar power station operators.
