LightCore™ Super Lightweight Design
The lightweight structure enables easy transportation and one-person deployment, making it ideal for commercial rooftop solar applications.
HydroFlex™ Wet & Dry Cleaning System
SolarWalker S2 LITE supports both dry sweeping and wet washing modes. Operators can choose the suitable cleaning method according to dust level, weather conditions, panel contamination and project requirements.
SafeEdge™ MultiLayer Safety System
Dual ultrasonic anti-fall sensors and slope anti-slip lock-up help improve operating safety on inclined solar panels and complex PV installation layouts.
CleanTune™ Adjustable Cleaning System
Three brush speeds and three moving speeds allow operators to adjust cleaning intensity and working efficiency for different dust levels, panel conditions and PV site requirements.
The S2 LITE features anti-microcrack, gap-crossing, tilt-adaptable, and 3-speed brush for comprehensive PV protection. TÜV-validated, it handles gaps and tilts easily, adapts to different dirt, and ensures long-term performance.
CrackProof™ Anti-Microcrack Protection Design
Validated through 20,000 TÜV micro-crack tests for reliable long-term solar panel cleaning.
Superior Gap Crossing
Horizontal gap ≤300mm, vertical gap ≤20mm
Wide Tilt Angle Compatibility
SolarWalker S2 LITE supports dry cleaning on PV modules with tilt angles below 33° and wet washing on modules with tilt angles below 25°, depending on site conditions and operating requirements.
3 Adjustable Brush Speeds
The brush speed can be adjusted to 120 / 140 / 160rpm, allowing operators to choose the proper cleaning intensity for light dust, regular dirt or heavier contamination.
The S2 LITE is compatible with all framed commercial and industrial PV modules, TÜV-certified, supports multi-array bridging, and flexibly adapts to complex layouts for thorough solar plant cleaning.
Compatible with All Framed industrial and commercial PV Modules
SolarWalker S2 LITE is compatible with common framed industrial and commercial PV modules, including M2, M4, M6, M10, G1 and G12 solar cell formats.
TÜV-Certified Quality and Reliability
SolarWalker S2 LITE is designed for professional PV cleaning applications and tested for long-term cleaning reliability. Warranty coverage is 1 year / 2400 hours / 1000km, whichever comes first.
Multi-Array Bridge Connection
SolarWalker S2 LITE supports bridge connection across multiple PV arrays, helping operators clean complex solar panel layouts with greater flexibility.
