1, bracket installation
The verticality deviation of the bracket is not more than 65438±0mm per meter, and the angle deviation of the bracket is not more than 65438 0 degrees. Generally speaking, the bracket should be installed neatly, the rear column should be vertical to the installation surface, and the main keel should be parallel to the installation surface. The mechanical installation hole of the component should be located near the two main keels, so the distance between the two main keels of the bracket should be 867- 1067mm when installing the bracket.
2. The photovoltaic bracket is grounded with 40*4 mm galvanized flat iron.
3. Installation of components. Before installation, determine the installation height of the components. The glass surface at the lower end of the module is 300mm from the ground. Fix the components with side blocks. First, fix the pressing block to prevent the parts from sliding. The frame of the member is 20-30mm away from both ends of the keel. When fixing, two people should cooperate with each other to determine the overall parallelism of assembly by drawing or level.
Definition and classification of photovoltaic bracket;
Definition of photovoltaic bracket:
Refers to the special bracket used to install and support solar panels. The difference between it and the traditional bracket is that the photovoltaic bracket needs to be customized according to the size and shape of the solar panel to meet the installation requirements in different environments. By fixing the photovoltaic bracket on the ground, roof or other structures, the solar panel can keep a certain inclination angle and receive solar radiation to the maximum extent.
Classification of photovoltaic supports
Photovoltaic supports mainly include columns, main beams, purlins, weldments, foundations and other components. At present, the common photovoltaic brackets on the market are divided into three types according to materials: concrete brackets, steel brackets and aluminum alloy brackets. The supporting materials used in these photovoltaic systems usually depend on the climate.
For example, when building photovoltaic systems in coastal areas, all structural components should be made of galvanized steel or aluminum, because such materials have high corrosion resistance. Among them, aluminum alloy bracket has become one of the hot products in photovoltaic bracket market because of its light weight, corrosion resistance and convenient installation.
