Flat Roof  Ballasted system

The concrete ballast ensures exceptional wind resistance and swift on-site installation. Its unique dual-orientation design promotes more efficient utilization of rooftop space and enhanced power generation.

Unique dual-orientation matrix design 

This unique design requires reducing structural costs and ballast weight. It also maintains flexible compatibility with concrete blocks or ballast foundations. 

Fully-Railed System and Shared-Rail System

Fully-Railed System: This system necessitates two rows of rails for each module of panels, enhancing the strength of the mounting brackets.
Shared-Rail System: In this configuration, every two panels share a middle rail, reducing the overall number of rails and attachments. This not only saves on installation time but also lowers costs.

Save time with pre-assembled components 
Pre-Assembled for efficiency, saving your time! 

High durability ensures structural strength
Professional design and the use of durable Zn-Al-Mg coated steel guarantee the stability and robustness of the structure.
