Description

Technical Field

[0001] This invention relates to the field of photovoltaic product application technology, specifically to a superimposed photovoltaic module installation system and its installation method. Background Technology

[0002] The current installation method for photovoltaic modules or panels is generally to lay them flat. The overlapping parts of the modules are fitted with adhesive strips for waterproofing. To prevent water leakage caused by the aging of the adhesive strips, a water collection channel is also needed under the frame. Water is diverted to the W-shaped water channel through the water collection channel, and gaps are left between the left and right modules to drain water through the W-shaped water channel.

[0003] While this solution can also achieve the problem of waterproofing the components, it is complicated to install and has high labor costs; it also requires the installation of horizontal and vertical drainage channels, which increases the overall cost.

[0004] To address the aforementioned shortcomings, a technical solution is provided. Summary of the Invention

[0005] The purpose of this invention is to provide a superimposed photovoltaic module installation system and its installation method.

[0006] The technical problem to be solved by this invention is as follows:

[0007] Existing technologies have poor waterproof performance of components, and the installation of waterproof components is cumbersome and labor-intensive; the installation of horizontal and vertical drainage channels is also costly.

[0008] The objective of this invention can be achieved through the following technical solutions:

[0009] A superimposed photovoltaic module installation system includes a left frame, a right frame, a top frame, a bottom frame, pressure blocks, water-blocking strips, horizontal keels, vertical keels, an aluminum alloy cover plate, and positioning hangers. The left and right frames have the same structure and are used for left-right overlap of the system, while the top and bottom frames are used for top-bottom overlap of the system. Several horizontal and vertical keels are provided and placed vertically. The horizontal keels are located above the vertical keels. The positioning hangers are fixed to the top of the horizontal keels with bolts and are used to hang the bottom frame.

[0010] Furthermore, both the left and right side frames include an I-shaped first support frame, with a first drainage groove provided at the bottom of both sides of the first support frame. One side of the first drainage groove is fixed with a pressure groove, and a first glass groove is provided on one side of the top of the first support frame, while a first adhesive strip groove is provided on the other side of the top of the first support frame.

[0011] Furthermore, the upper frame includes a second support frame, and a second glass groove is formed on one side of the top of the second support frame.

[0012] Furthermore, the lower frame includes a third support frame, a third glass groove is provided on one side of the top of the third support frame, a second adhesive strip groove is provided on the other side of the top of the third support frame, and a second drainage groove is provided on one side of the second adhesive strip groove.

[0013] Furthermore, the first glass trough, the second glass trough, and the third glass trough are all used to install photovoltaic modules.

[0014] Furthermore, the photovoltaic module is made by inserting adhesive strips into the frame of a photovoltaic panel and then installing an aluminum alloy frame.

[0015] A method for installing cascaded photovoltaic modules includes the following steps:

[0016] Step 1: Insert adhesive strips into the frame of the photovoltaic panel, install the aluminum alloy frame, and process it into a photovoltaic module;

[0017] Step 2: Evenly place several longitudinal keels at the bottom of several transverse keels and set them vertically;

[0018] Step 3: At the intersection of one row of horizontal and vertical keels, fix the positioning point to the top of the horizontal keel with bolts, fix the lower frame to the positioning point, set the second glass groove on the upper frame and the third glass groove on the lower frame facing each other, and set a water-blocking strip between the bottom of the upper frame and the top of the lower frame to complete the upper and lower overlap.

[0019] Step 4: Set the left and right frames opposite each other so that the two pressure grooves on the two first support frames are adjacent. Connect the bottom of the left and right frames with pressure blocks, and connect the top of the left and right frames with aluminum alloy cover plates. Fix the pressure blocks to the top of the horizontal keel with bolts to complete the left and right overlap.

[0020] Step 5: Install the photovoltaic modules sequentially in the adjacent first glass trough, second glass trough, and third glass trough. Continue this process until the first row of products is installed. Install each row of products in the same way.

[0021] The beneficial effects of this invention are:

[0022] This invention solves the problem of cumbersome installation of photovoltaic modules or panels in the building industry. The left and right overlaps are fixed with clamping blocks, and the top is covered with an aluminum alloy cover plate, with drainage grooves in the frame. The left and right modules do not affect each other and are easy to replace; the combination of the top cover plate and drainage grooves greatly improves the waterproof performance of the product, while the clamping blocks can prevent wind but do not affect the product's deformation due to thermal expansion and contraction.

[0023] This invention overcomes the drawback of high construction and installation costs when photovoltaic products are installed in the building sector; it also overcomes the cumbersome installation process of photovoltaic modules in some existing technologies, improving installation efficiency; and it overcomes the cost disadvantage of existing modules requiring drainage channels, bolts, or clamps, as this product itself has a built-in waterproof system and does not require external drainage channels, effectively reducing product costs.
