1)Ground mounting structure with cement base applies to sandy soil and hard clay. Its lifetime is long and not easy to sink. 

2)U channel with row holes enhance the adjustability of whole structure. For horizontal solar panel layout structure, poles are with angle. Cross beam can put on it directly and fasten with bolts. There is no need to adjust tilt, which reduce installation period and cost. 

3)According triangle theory, this structure is stable with high strong wind and heavy wind resistance ability.  

4)Less welding, easy to processing and modular manufacturing. Delivery time is about 10 days. 

5)Can be customized.
