Against the backdrop of the accelerated global shift toward a low-carbon and clean energy mix, photovoltaic power generation is experiencing unprecedented growth. Industry statistics show that China’s cumulative installed PV capacity maintained its global lead in 2025, with synchronous expansion of distributed solar systems and large-scale ground-mounted power stations, and rooftop PV systems gaining popularity among households. Nevertheless, behind the rapid expansion of the PV industry lies a long-underestimated yet critical link: the cleaning and maintenance of photovoltaic modules.
A dusty module is quietly eroding your revenue
Photovoltaic modules generate electricity from sunlight, and their power output is directly tied to the cleanliness of their surface. Exposed outdoors for long periods, solar panels are constantly subjected to sand, dust, bird droppings and oil contamination, which gradually form a layer of grime on the surface. Scientific measurements prove that the impact of dust accumulation on power generation is far greater than most people expect:
(after consecutive dry days with no rainfall): around 5%–10% loss in power output;
(long-term neglect, sites near construction zones or sandy regions): power loss can exceed 30%.
For a 10 MW solar power plant, even based on a conservative 10% output loss, the annual economic loss can easily reach hundreds of thousands of yuan. For residential PV owners, dust buildup also translates directly into reduced electricity income. Cleaning solar panels has shifted from an optional service to an essential requirement.
Pain points of traditional cleaning methods: high cost, low efficiency and risk of panel damage
Three conventional approaches have long been used for PV cleaning: manual wiping with cloths, high-pressure water washing, and professional cleaning robots. Each comes with obvious drawbacks:
Labor-intensive and slow, with rising labor costs and safety risks for high-altitude work.
Fast but consumes large volumes of water. Improper water pressure can also crack or damage modules.
High price tag. Not cost-effective for small and medium-sized stations or residential projects.
Targeting these market challenges, MULTIFIT, a specialist manufacturer of solar cleaning equipment, has launched an efficient, user-friendly and cost-effective solution —
MULTIFIT solar panel cleaning roller brush
MULTIFIT Solar Cleaning Roller Brush: an efficient “eraser” for solar panels
- 1.
Efficient cleaning for spotless results
Equipped with dense soft bristles and rotating cleaning action, the roller thoroughly removes stubborn dust, bird droppings and oil stains without scratching the glass surface.
- 2.
Labor-saving and multi-purpose telescopic pole
Operators clean large areas while standing on the ground. It cuts labor costs and safety hazards significantly, ideal for residential rooftops and agricultural greenhouses.
- 3.
Durable and cost-effective
The brush head adopts weather-resistant raw materials. Deliver consistent cleaning performance at a much lower investment than expensive robots.
- 4.
Wide application scenarios
Beyond solar panels, it is also suitable for cleaning greenhouse transparent sheets, billboards and building curtain walls.
A small cleaning step, a big gain in power output
In the era of grid parity for solar power, every kilowatt-hour counts. Timely, proper and low-cost module cleaning is one of the most straightforward ways to boost power generation and improve the return on investment of solar assets.
