Sol-Bright Technology’s latest generation robot for 1P tracker systems represents a significant advancement in automated solar panel maintenance. Purpose-built to meet the complex demands of utility-scale solar operations, this robotic cleaner offers an intelligent, durable, and highly efficient solution for maintaining panel cleanliness while minimizing labor and water dependency.
Intelligent Engineering for Smart Solar Maintenance
The latest generation robot is powered by a brushless DC motor and a dry roller-brush cleaning system, designed for reliable and eco-friendly performance. It operates entirely on a 24V DC power supply and is self-charging via a 170Wp–200Wp photovoltaic panel mounted on the docking station. This intelligent energy autonomy ensures sustainable operation without external power sources, making it ideal for remote or off-grid installations.
Advanced communication capabilities such as LoRaWAN and RF433MHz enable seamless SCADA integration for wireless remote control, while Modbus TCP/IP compatibility supports broader industrial automation frameworks. A manual mode is also available, operated via a portable remote controller, providing flexibility in deployment and troubleshooting.
Designed for Performance, Built for Resilience
Constructed with a lightweight yet torsionally adaptable structure, the robot can accommodate ±25° of twisting, allowing it to adjust dynamically to horizontal and vertical misalignments in tracker rows. This capability, combined with posture correction via gyroscopic technology, ensures consistent and thorough cleaning even on uneven terrain or with irregular panel placements.
The cleaning mechanism features UV-resistant bristles rotating at 130 RPM (±10%), delivering effective debris removal without damaging the panel surface. Operationally quiet at below 60 dB, the robot ensures high-performance cleaning with minimal disruption.
Robust Environmental Adaptability
The latest generation robot thrives in challenging environments. It operates across a temperature range of -40°C to 70°C and humidity levels up to 95%, functioning efficiently after rainfall or in humid conditions. It can operate at wind speeds up to 26 m/s, supported by a comprehensive windproof system that includes an anti-dropping hook, windproof lock, and step motors for anchoring.
Capable of climbing angles up to 30° on short bridge spans and handling terrain slopes under 8°, the robot is suited to both structured tracker fields and complex landscapes. With a recommended cleaning frequency of once per day especially in desert solar farms it maintains optimal panel performance, achieving a cleaning efficiency of ≥99.5% and an uptime rate of ≥98.5%.
Reliable and Eco-Conscious Solution
Rated IP65 for dust and water protection, the latest generation robot is both durable and environmentally friendly. It produces no waste or toxic byproducts, aligning perfectly with green energy principles. The system is backed by a two-year standard warranty, with Sol-Bright providing full maintenance services and spare parts support throughout the coverage period.
In essence, Sol-Bright’s latest generation robot is not just a product it’s a smart, high-performance solution that embodies the future of sustainable and efficient solar O&M.
