Application Scenarios of the Product Series
The application of this product series strictly aligns with the three dimensions of PV power plants: "scale, installation environment, and automation requirements", achieving full-scenario coverage from small household systems to large-scale power plants:2.1 Household/Small-Scale Distributed Power Plants (<10kW, Area: 50-100㎡)
Most of these power plants are installed on rooftops, with limited space and low cleaning frequency (1-2 times a month). Manual models with flexible operation and low cost are preferred:Flat rooftops or small sloped areas (<50㎡): Single-head disc brush is recommended, which can be operated by one person independently, especially suitable for PV arrays on rural self-built houses;Medium-sized rooftop areas (50-100㎡): Double-head disc brush or manual push-type roller brush is recommended. The double-head model improves efficiency, while the manual push-type roller brush is suitable for flat rooftops, reducing fatigue caused by bending.2.2 Small and Medium-Sized Industrial/Commercial Power Plants (10kW-1MW, Area: 100-10000㎡)
Most of these power plants are installed on factory rooftops or small ground arrays, with high cleaning frequency (once a week). Semi-automatic or simple fully automatic models are preferred to balance efficiency and cost:Sloped factory rooftops (inclination angle: 15-25°): Electric roller brush is recommended, equipped with an extended power cord or lithium battery model. One person can clean 500-800㎡ per day, suitable for rooftop power plants of electronics factories, garment factories, etc.;Small ground-mounted flat arrays: Solar-powered orbital brush is recommended. The rails are customized according to the length of the panel array, requiring no external power supply and realizing automatic scheduled cleaning, suitable for distributed power plants in industrial parks to reduce labor costs.2.3 Large-Scale Ground-Mounted Centralized Power Plants (≥1MW, Area: >10000㎡)
These power plants are large in scale, located in remote areas (mostly deserts, Gobi, and grasslands), with heavy dust and high labor costs. Fully automatic intelligent models are preferred:Standardized large-area flat arrays: Solar-powered orbital brush is recommended. Rails are installed in divided blocks, and multiple main units work simultaneously, with a cleaning efficiency of 10,000-20,000㎡ per day, suitable for desert PV power plants;Complex terrain or non-standard arrays: Remote-controlled robotic brush is recommended. The tracked walking mechanism adapts to undulating terrain, and visual navigation avoids obstacles. Multiple robots can work in coordination, suitable for mountain PV power plants or agri-PV complementary projects.2.4 Applications in Special Environments
Dusty/Windy Environments (e.g., Northwest Gobi): All products should adopt enhanced dust-proof bearings. Roller brushes or disc brushes should use high-density bristles to prevent sand and dust from entering the interior and causing jamming; orbital brushes or robotic brushes are preferred to reduce the time workers are exposed to harsh environments;High-Humidity/Rainy Environments (e.g., Southern Coastal Areas): The bracket or body material should be upgraded to 304 stainless steel. Mold inhibitors should be added to the brush bristles, and the electric models should strengthen the circuit waterproof sealing; dry-wet dual-purpose models (e.g., roller brushes with spray function) are recommended to use rainwater for auxiliary cleaning and reduce water consumption;Low-Temperature/High-Altitude Environments (e.g., Qinghai-Tibet Plateau): Batteries should use low-temperature adaptive models (supporting startup at -30℃). Brush bristles should be made of low-temperature resistant elastic materials to avoid brittleness and cracking; orbital brushes should be equipped with heating devices to prevent snow from freezing the rails.III.
