The role of the solar panel mounting bracket is to protect the photovoltaic module from 30 years of damage such as light, corrosion, and wind. There are many materials for the solar mounting bracket, the special photovoltaic solar array mounting bracket, the material is carbon steel Q235, using hot-dip galvanizing process, the average galvanizing thickness is 65μm, the basic thickness of the solar support bracket thickness can be equal to or greater than 2.5mm, pressure resistance, anti-wind, Corrosion resistance is very good. In order to save costs, some companies use angle iron as a bracket. After a long time, the bracket is easy to rust and deform.
The connection between the solar support brackets must be assembled with nuts and connectors, and some companies use solder assembly directly, which is easy to break and collapse over time. The bracket assembled by the nut and the connecting piece is easy to disassemble, and the welding assembly must be cut to be removed, which affects the user's interests. Let's talk about counterweights. The most common ones on the market today are concrete piers, steel structures, and chemical anchor bolts.
Households generally use concrete piers that are installed to meet the installation standards of the photovoltaic industry as a counterweight, generally a square solid cement pier. Some companies simply ignore the national standards and directly use the expansion bolts to fix the brackets on the roof. This not only destroys the waterproof layer of the roof, but also loosens the expansion bolts after a long time. Still others use hollow concrete piers that are not up to standard. A lot of news about a certain solar photovoltaic panel being scraped and dropped caused a certain economic loss, basically this is the case, so the bracket and counterweight are very important for the placement of solar photovoltaic panels.
