Product Introduction
The self-cleaning system is a proactive protection technology developed specifically for complex outdoor environments. It efficiently removes pollutants such as dust and bird droppings from the surface of solar panels through physical means, ensuring that the light transmittance remains stable above 92% and increasing the power generation efficiency by 20%-35%. It significantly reduces the risk of performance degradation caused by dust accumulation.
This system is especially suitable for installations on high poles (≥12 meters), in remote areas (where the cost of manual maintenance is high), and in extreme climate scenarios (such as regions prone to frequent sandstorms and coastal areas with high humidity). It can achieve maintenance-free operation for more than 10 years and is compatible with dual-axis tracking technology to further optimize the utilization rate of low-angle sunlight.
Core Functions
1. Dual-mode Driving Mechanism
Active Driving Mode: A built-in micro motor drives the cleaning brush (materials: silicone/ultrafine fiber) to move back and forth along the surface of the solar panel. The cleaning process is triggered by a preset program (for example, automatically starting at 2 a.m. every day) or a remote command.
Passive Driving Mode: It utilizes natural forces (such as wind and rainfall) to assist with cleaning. For instance, it achieves self-flushing with rainwater through the inclined angle of the panel surface (15°-30°) and the hydrophobic coating on the surface (contact angle ≥110°), reducing the need for manual intervention.
2. Pollutant Removal Mechanism
● Coverage of Multiple Types of Pollutants: The cleaning brush can effectively remove obstructions such as dust (PM2.5-PM10), fallen leaves, bird droppings, and insect carcasses, preventing a decrease in power generation efficiency caused by a drop in light transmittance.
● High-frequency Cleaning Strategy: In areas with dense dust (such as industrial parks and around construction sites), the cleaning frequency can be set to twice a day to prevent fine particles (particle size ≤10μm) from accumulating to form oily stains, ensuring that the surface cleanliness of the solar panel (in accordance with ISO 8573-1 standard) remains at Class 1 level for a long time.
Improvement in Light Transmittance and Power Generation
1. Performance Comparison in Sand-dust Weather
Without a Self-cleaning System
In a sandstorm environment with a PM10 concentration > 500μg/m³, the light transmittance of the solar panel can drop below 45% within 72 hours, resulting in a power generation decrease of over 55%.
With a Self-cleaning System
Through mechanical cleaning twice a day, the light transmittance can be stably maintained above 92% for a long time (measured data: it recovers to 98% of the initial value 24 hours after the sandstorm). Under the same light intensity (1000W/m²), the daily power generation is increased by 28%-35%.
2. Long-term Assurance in Industrial Dust Areas
In areas with dense dust emissions such as cement plants and mining sites, the nanoscale fibers of the cleaning brush can penetrate the texture of the solar panel (surface roughness Ra ≤0.8μm) and remove embedded particles, avoiding local hotspots (temperature increase > 15℃) caused by electrostatic adsorption, thus extending the lifespan of the solar cells (the L70 lifespan is extended by 15%-20%).
