How to choice a solution for concrete roof top system one may ask, HQ Mount hereby introduce some commonly used solution:

1.A low racking system which does require to have space for activity. For this solution in Some of Africa area the concrete block is not required for the raining is seldom so the leaking are not the problem to consider about. And for other areas like Mid-East Aisa it’s commonly used as the photo shown.

2.A High Hot Dip Galvanized Solar Roof Mounting System Which Allows Activities to Happen. This solar usually request the pole for solar mounting to be around 2 meters high.In this solution, the most structure is HDG Surface Q235 Material with 80μm treatment.

3.The same request as 2nd but using aluminum anodized profile surface. This is actually used for solar carport but also applied for solar roof top which is light and looks better than carbon steel mounting structure.

4.The mostly suggested solution- Ballasted solution.This solution saves a lot of installation time and material, and also suitable for all kinds of solar panels. The above solutions, if the panel size changes, the structure usually needs to be changed accordingly. But this ballasted solution is more stocking friendly.

However, Solar ballasted solution does have a more strict environment requirements. For example, the wind speed should be under 40m/s, the angle should be 10Degrees or 15 Degrees. If the condition is different, some enforcement may be considered.
