The solar water heater bracket is the supporting element of the solar water tank, an important part of the solar water heater, and plays an important role in the promotion of the solar water heater. Today, solar mounting brackets are developing into an independent small industry, and more and more companies are producing solar mounting brackets, making the mounting brackets independent from the division of labor in the solar water heater industry. In the popularization of solar water heaters, solar brackets have played an important role and become one of the important parameters for people to purchase solar water heaters. The bracket design of the domestic solar water heater should be reasonable, and it should have sufficient strength and rigidity to ensure sufficient load-bearing capacity. In some areas with strong daily wind, especially in coastal areas, when purchasing household solar water heaters, you should also pay attention to whether the product has wind resistance in design. Generally good quality solar water heaters use aluminum alloy brackets, which are thick and firm.

Solar photovoltaic bracket is a special bracket designed for placing, installing and fixing solar panels in the solar photovoltaic power generation system. The general materials are aluminum alloy and stainless steel. Photovoltaic bracket products are divided into ground type, roof type, wall type, portable, etc.

Large-scale photovoltaic power generation enterprises generally use galvanized metal materials. First, the cost is low, and the second is that it has a large load and has a rotating device, which can adjust the angle itself with the rotation of the sun, and the utilization rate of light energy is high.

When some customers and friends choose solar photovoltaic brackets, they can see that there are many different styles of products. Of course, there are also some differences in the installation methods of different styles of brackets, in order to meet the application needs of different places and regions. To make the solar panel more stable and reliable, we are also very important in the selection of brackets. The following editor will introduce several photovoltaic brackets and installation specifications and dimensions.

Preparations before installation:

1. When the photovoltaic support arrives at the construction site before installation, an effective part should be selected, and at the same time, the surrounding environment should be kept naturally ventilated and dry. After the fixing bracket and components arrive at the construction site, check whether the outer packaging box is deformed or damaged. If there is any damage, please contact the manufacturer to replace it immediately.

2. Check on the spot before construction, and after there is no problem, carry out construction set-out according to the reference line shown in the design drawings, and control the oblique angle of the square array. Calculate the construction drawings, clarify the area of the fixed bracket guide rails, accessories and parts used, and load the materials in stages according to the total area spread and the construction process.

Installation of support frame and module:

According to the design drawing, firstly carry out precise positioning construction and lay-out, mainly for the precise positioning of the fixture for the color steel top, and then install the guide rail, you should pay attention to the fixture, the same row of component guide rails, and the distance between the two adjacent rows of component guide rails. When installing, it should be carried out in the order of the middle area, the two sides, and the guide rail connector. After installing the guide rail connector, check the flatness of each guide rail, bend each span, and carry out precise strength calibration on the support frame. nuclear. The distance between the seats should be paid attention to in the formulation, and the distance between the seat and the wall should be specified. In addition, when installing the support frame poles, load-bearing beams and guide rails, it is not necessary to tighten the anchor bolts at one time in time. After all the support frames are adjusted vertically, all the anchor bolts are tightened.

Component installation

(a) Installation of fixed solar panels

The installation of solar panels should be carried out gradually from the top to the top, and ensure that the horizontal and vertical directions are maintained, and the distance between the panels in the same direction is kept the same. At the same time, it is necessary to pay attention to the wiring orientation of the panels. When the battery plate is fixed, use anchor bolts to fix the components on the sprocket in the steel frame structure, add a double thorn washer between the battery plate and the guide rail, put on the middle clamp and the side clamp, and lock it with a nut. .

 Panel connection

According to the design drawings, the interface method of the battery board should be clarified. When wiring, it is necessary to pay attention not to connect the positive and negative stages incorrectly, so as to ensure proper wiring. After each battery board is connected, check whether the short-circuit working voltage of the battery board string is appropriate. After the close connection is made, the route on the battery board should be disconnected, and the actual operation of the subsequent process flow should be carried out.

Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation; photovoltaic effect It refers to the phenomenon in which a potential difference is generated between uneven semiconductors or parts where semiconductors and metals are combined when illuminated.

 In the related art, during the installation of photovoltaic panels, it is first necessary to select the appropriate direction according to the geographical location, then fix the brackets in the corresponding orientation, and then fix the photovoltaic panels on the brackets by bolts to realize the installation of photovoltaic panels. .

 In view of the above-mentioned related technologies, the inventor believes that the long-term exposure of photovoltaic panels to the air will cause damage to photovoltaic panels and shorten the service life of photovoltaic panels when encountering rain and snow weather.
