Problems solved by technology

For a system with a relatively high photovoltaic array design, it is necessary to increase manpower to ensure that the installation is in place. At the same time, it takes time to adjust the relative position of the photovoltaic module and the guide rail. The installation efficiency of the photovoltaic module is low; The locking torque does not meet the technical requirements. Under the long-term outdoor wind load, it is easy to cause the frame fatigue failure or the frame slipping from the pressing block.

Embodiment 1

[0055] like figure 1 As shown, the present embodiment provides a photovoltaic system, including a laminate 4 and a photovoltaic component installation structure, and the photovoltaic component installation structure includes a frame 2, a guide rail 1 and a bracket 3. The laminate 4 is arranged on the frame 2, and the frame 2 is fixed on the guide rail 1. The photovoltaic module mounting structure can protect the laminate 4 and prevent the laminate 4 from being corroded or damaged by wind.

[0056] like figure 1 and figure 2 As shown, the laminate 4 has a rectangular structure, and the laminate 4 includes a front panel, a rear panel, and a string of battery cells disposed between the front panel and the rear panel. The cell string is composed of multiple cells. Multiple cells are connected in series to obtain high voltage first, and then connected in parallel to obtain high current. Then, a diode is used to prevent current from returning to output to achieve power output. B...

Embodiment 2

[0101] like Figure 9 As shown, the present embodiment provides a photovoltaic system, which is different from the first embodiment in that the guide rail 1 is also provided with a puncturing part 15, and the puncturing part 15 can puncture the protection during the installation process of the frame 2 layer and contact with the frame 2 so that the frame 2 can be reliably grounded.

[0102] like Figure 10 As shown, the piercing portion 15 includes an edge extending along the direction of the frame 2, and the edge can pierce the protective layer during the sliding process of the frame 2. Through the relative movement of the piercing portion 15 and the frame 2, the piercing effect is improved, So as to achieve a stable and continuous grounding effect.

[0103] In order to simplify the structure of the guide rail 1 and improve the piercing effect of the piercing part 15, the piercing part 15 can be formed by stamping the guide rail 1. Specifically, the guide rail 1 is provided...

Abstract

The invention relates to the field of photovoltaic technology, in particular to a photovoltaic module installation structure and a photovoltaic system. The photovoltaic module installation structure includes a frame and a guide rail. The frame can be slid into the guide rail along the length direction of the guide rail. One of the guide rail and the frame is provided with an elastic protrusion, and the other A card slot is provided, and after the frame is installed in place, the elastic protrusion can cooperate with the guide rail and the frame card slot to limit the position of the guide rail and the frame. In the photovoltaic module installation structure, the frame and the guide rail are slidably installed, and the frame can be quickly installed on the guide rail without using bolts or pressing blocks, etc., which is convenient for installation and high in efficiency; without using bolts or pressing blocks, the frame can be reduced The stress concentration of the frame and the guide rail can improve the strength; after the frame and the guide rail are installed in place, the elastic protrusions and the card slots are used to limit the position, so as to improve the fixing effect of the frame and the guide rail.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a photovoltaic component installation structure and a photovoltaic system. Background technique [0002] Photovoltaic modules are the core part of the solar power generation system and the most important part of the solar power generation system. The photovoltaic module includes a laminate and a photovoltaic module frame, and the photovoltaic module frame is used to encapsulate and protect the surrounding of the laminate. The frame of the PV module is fixed on the guide rail, which can protect the PV module and prevent the module from being corroded or damaged by wind. [0003] In the prior art, the frame of the photovoltaic module and the photovoltaic guide rail are connected by means of bolt connection or pressure block installation. For a system with a relatively high photovoltaic array design, it is necessary to increase the manpower to ensure the installation in plac...
