How To Install The Pv Bracket Of Different Types Of Roof?
Mar 21, 2018

Photovoltaic supports are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. The general material is aluminum alloy, carbon steel and stainless steel. In the specific installation process, you need to choose the appropriate installation method according to different types of roofs


Cement roof-mounted solar rack systems

1. On-site pouring cement foundation.

Advantages: integrated with the roof, solid foundation, less cement.

Disadvantages: It is necessary to pre-embed the steel bar on the roof of the building, or use an expansion screw to connect the cement foundation and the roof together. This will easily damage the waterproof layer of the roof, and it will leak for a long time.


2. It is necessary to accurately calculate the average annual wind speed at the project site and the wind direction in different seasons, and calculate the positive and negative wind pressures. Then calculate the weight of the cement foundation by the wind pressure. Pre-processed cement blocks of consistent dimensions and transported to the site for installation


 Tin roof structure

Tin roof mounted rack is generally used in light steel structure buildings more common in standardized factory buildings and warehouses. Lightweight steel structures use lightweight steel tile roofs as roofs, and spans can be very large. It is very suitable for large-scale laying of solar modules. Urban industrial parks are standard factory buildings that are built together. They are large in size and often can build tens of megawatts of solar power stations at a time.


Tin roof mounted rack is composed of a thin metal plate wrapped with a foam plate, and the bracket of the battery assembly cannot be fixed by a conventional method. Need to use a dedicated "fixture", the use of fixtures will not destroy the original structure, will not lead to leaking roof or overall structural damage.

From the load-bearing point of view: If installed in accordance with the best angle, it is inevitable to use more support, increase the weight of the roof. From a safety point of view, according to the best inclination angle, the components cannot be parallel to the roof, causing additional wind pressure when the wind blows, creating a potential safety hazard. To sum up, the components can only be tiled on the roof of the color steel tile. The number of components installed is only related to the roof area and bearing weight, and there is no optimization.


Tile roof structure

This refers to the wooden under the tile surface. The installation method is generally to open the tile. Drill the screw up and down the wooden, install the hook adapter, and then cover the tile back. The key is to control the position of the  screw. Distance from the lower edge of the tile. If you want to look good, you may also need to saw the bottom of the tile out of a gap. Special attention should be paid to the thickness of the concrete, which cannot damage the waterproof structure of the roof.
