1. Track angle from 30^o  to 150^o 
2. Rated area for installation of solar panel:30m²
3. Rated carrying capacity:800kg*N
4. Peak wind:50m/s
5. System protection wind: 23m/s(solar panels become plane)
6. Average power expenditure of the system:<2W *N
7. Output power is higher than fixed system by at least 12% per year
8. Initiative track. The geographic location can be input in the system, and the solar panel will follow the sun initiatively.
9. Function of the controlling system: automatically rack, automatically reposition, automatically protection, check out, hand control, data collection, display, communication, long-distance monitoring, environment monitoring, group control.
