Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, and in particular relates to a photovoltaic component installation and retention device for a glass balcony guardrail. Background Art

[0002] One of the most important aspects of sustainable development is to address society's energy needs and use. While there is a limit to what can be done to reduce consumption, the source of energy supply can be considered. This is where renewable energy sources such as photovoltaic solar energy come in. In terms of cost and financial return, the most important component of a photovoltaic system is the photovoltaic solar module. Photovoltaic solar modules capture sunlight and convert it into electrical energy. Depending on the actual implementation of the photovoltaic system, the energy can be stored in batteries, or provide energy for DC or AC loads, or convert DC into AC and feed it back to the grid. Over the past few decades, thanks to technological advances in the photovoltaic solar industry, especially technological advances in photovoltaic solar cells, and economies of scale, the annual installed capacity of photovoltaic solar energy and the expansion of the application range of photovoltaic power generation technology have greatly increased. Compared with traditional glass photovoltaic modules, weather-resistant non-glass semi-flexible lightweight modules not only have almost the same life cycle, but also have the advantages of light weight, resistance to mechanical impact such as knocks, stain resistance, safety, no light pollution, low installation cost, and beautiful appearance. They are very suitable for vertically installed balcony photovoltaic power generation and other application scenarios with low requirements for hail impact resistance. Thanks to the improvement in efficiency and reduction in cost of photovoltaic solar cells, as well as the commercialization of weather-resistant non-glass semi-flexible lightweight module technology, the market demand for balcony photovoltaic power generation systems has also expanded year by year.

[0003] The existing balcony photovoltaic module installation method is to open a number of holes around the flexible photovoltaic module, install metal buckles, and fix it to the horizontal handrail of the balcony railing with a cable tie in the vertical direction; fix it to the vertical rod of the guardrail with a cable tie in the horizontal direction, or interconnect the modules with cable ties. The advantage of this method is that it is easy to install. However, when the above installation method is applied to the glass guardrail balcony, there are problems in the following aspects:

[0004] 1. Poor stability: The glass guardrail balcony lacks rods for tying ties in both the vertical and horizontal directions, making the fixed flexible components unstable and prone to shaking;

[0005] 2. Noise and reliability risks: Flexible photovoltaic modules are fixed by tying them with ropes around the glass. When blown by gusts of wind, the flexible photovoltaic modules will hit the guardrails and produce noise. At the same time, they may vibrate periodically, causing cracks in the crystalline silicon solar cells of the flexible photovoltaic modules, damage to the welding alloy layer between the interconnection welding ribbon and the battery cell, and breakage of the interconnection welding ribbon, posing a serious threat to the long-term reliability of the flexible photovoltaic modules.

[0006] 3. Poor aesthetics: The method of fixing flexible photovoltaic modules by tying them around the glass with ropes is not aesthetically pleasing;

[0007] Therefore, a glass balcony guardrail photovoltaic module installation and retention device is needed to solve the problems in the prior art of poor stability of the installed flexible photovoltaic modules, noise and reliability risks, and flexible light

[0008] The problem of poor aesthetics of volt components. Utility Model Content

[0011] It should be noted in the scheme that the installation assembly includes symmetrically distributed fish-mouth clamps, which are detachably connected to the other side of the glass guardrail body, and an adapter plate is fixed to one side of the two fish-mouth clamps.

[0012] It is further worth mentioning that a silicone rubber pad is fixed to the inner side wall of the clamping plate, and the silicone rubber pad is engaged with the top and bottom ends of the glass guardrail body.

[0013] It should be further explained that a micro inverter is fixed on one side of the adapter plate.

[0014] As a preferred implementation, the adapter plate is a Z-shaped structure.

[0015] Compared with the prior art, the glass balcony guardrail photovoltaic module installation and retention device provided by the utility model has at least the following beneficial effects:

[0016] (1) By providing the clamping plate and the silicone rubber pad, the clamping plate can be stably connected to the glass guardrail, thereby preventing the flexible photovoltaic module from shaking after being fixed.

[0018] (3) The splints and tie bands are provided to simplify the structure of the connection between the flexible photovoltaic module and the glass guardrail, thereby improving the aesthetics of the flexible photovoltaic module after fixation.

[0019] (4) The fish-mouth clamp and adapter plate can be installed without punching holes, which improves the convenience of installing the micro-inverter. BRIEF DESCRIPTION OF THE DRAWINGS
