1. First clean the debris on the roof. Use a tape measure to measure the installation position of the foundation on the roof, and place the foundation of the flat roof solar mounting system.
2. Use a hammer drill to make holes in the cement foundation. The depth of the hole is determined by the thickness of the foundation and the length of the bolt.
3. Put the expansion bolt into the hole. Use a non-metallic hammer such as a wooden or leather hammer to lightly tap the bolt into the hole.
4. Install the bottom beam or base. Align the bottom beam hole or base hole with the bolt and use a wrench to tighten the nut.
5. Measure the installation position of the rear column according to the angle of the bracket. Bolt the base to the rear post.
6. Fix the inclined beam. Use screws to fix it with the rear column and connect the inclined beam to the base with bolts.
7. Install the solar module with mid clamp and end clamp.
