Explanation of the design points of solar roof mount system Aug 8,2022.
The design of the solar mount should be as simple as possible, reasonable in force, firm and reliable, durable, economical in cost and easy to construct, and fully consider factors such as load-bearing, wind resistance, earthquake resistance, and corrosion resistance.

The solar mount design should also consider reducing welding as much as possible, preferably using hinged or screw-fixed combined connection, which is convenient for installation, adjustment and removal.

When designing the solar mount, the selection and design of the solar mount should be carried out according to the capacity design of the photovoltaic power generation system, the calculated number and size of the photovoltaic modules, the optimal inclination angle of the square array, the installation position and installation method of the photovoltaic modules, etc.

solar roof mount system

The design of roof solar brackets should be carried out according to different roof structures. For sloped roofs, brackets parallel to the slope of the roof can be designed. The height of the brackets is about 10~15cm away from the roof surface to facilitate the ventilation and heat dissipation of solar modules. It can also be designed as a roof inclination bracket with a low front and a high back according to the optimal inclination angle to meet the maximum solar energy reception of solar modules. The flat roof is generally designed as a triangular bracket, and the angle of the inclined surface of the bracket is the optimal receiving inclination angle of the solar module.

The roof solar support must be connected to the main structure of the building, not to the roof material. If the concrete and cement foundation is used to fix the bracket on the roof. Or the roof is drilled with pre-embedded steel bars, or the roof surface of the foundation part is treated to be uneven to increase the adhesion between the roof surface and the concrete foundation, and then secondary waterproofing treatment is performed on the damaged part of the roof waterproof layer.

For roofs that cannot be used as concrete foundations, the solar modules are generally fixed directly with angle steel brackets. The fixing of the brackets requires the use of wire rope.
