PV system design of the roof stent

Roof stent design to be carried out depending on the roof structure, respectively, may be designed for the slopes of the roof and the roof inclination parallel shelves, height of the stand about 10cm from the roof surface, both in favor of ventilation components of photovoltaic cells to be based on best the inclination angle of designed low to high before the bracket in order to meet the photovoltaic modules to receive the maximum amount of solar energy, flat roofs are generally designed as a triangle stents, stent slope angle of a photovoltaic cell receiving optimal tilt angle three stent design .

If by way of concrete cement base mounting bracket on the roof, the roof will need to uncover a part of the waterproof layer, pull open the concrete surface, it is best to find the roof of reinforced concrete, and then the foundation bolts embedded parts welded together. Can not be welded steel, the foundation will make part of the roof surface irregularities, increasing the roof surface adhesion with concrete foundation and roof waterproofing destroyed part do secondary water treatment.
