Traditional solar panels are primarily designed to be installed on rooftops, open spaces, and other locations where they are not subjected to significant physical stress other than the weight of wind or snow. However, in many regions, rooftop installation is not possible due to tornado hazards, urban landscape preservation regulations, roof structure limitations, or lack of available rooftop space, leading to an increasing demand for walkable solar panels.

However, the surface design of traditional solar panel assemblies is not suitable for walking and has some limitations in pedestrian walkways or similar applications. This is because the upper edge of the aluminum frame typically extends above the glass, causing the accumulation of water, mud, and debris, which blocks sunlight and reduces the efficiency of the solar cells. Additionally, there is a safety risk as the surface of the solar cells can become slippery or dangerous. Moreover, the frame edges protruding above the panel are easily damaged by pedestrians, and footwear can wear or weaken the aluminum material, and repeated impacts can weaken the structural integrity of the frame.

Detailed Implementation

[0030] The inventors of this application discovered through research on existing technologies that:

[0031] Figure 1 The cross-section of a prior art solar panel assembly shows that the core component of the solar panel 10 is the photovoltaic cell, which is responsible for converting sunlight into electrical energy. These cells are typically made of silicon and are usually arranged in a grid pattern on the surface of the solar panel 10. To protect these cells, they are layered with two layers of encapsulant 16, a backsheet 17 (a durable, weather-resistant polymer layer on the back), and a light-transmitting layer 18 on the front. This encapsulation ensures that the unit remains intact and functional over a long period of time. Around the edges is a frame 13, preferably lightweight and corrosion-resistant. This frame provides structural integrity and facilitates the mounting of the panel to various surfaces and its horizontal sections 15. Standard frames typically have a single vertical chamber 11 for accommodating corner connectors and components extending onto the light-transmitting layer 14. The internal portions of the frame are typically filled with edge sealant 12. Typically, solar panels use tempered glass with a thickness D1 of 3-4 mm.

[0032] Figure 2 This is a schematic diagram of the installation of a prior art solar panel assembly. In this system, the solar panel 10 is secured using mounting clamps 21, mounting clips 23, and bolts 22 attached to a frame 13. This design ensures that the light-transmitting layer 18 remains unobstructed and unclamped, thus preventing any potential damage to the light-transmitting layer. The mounting clamps 21 are connected to a bracket 28, which provides a stable platform for the solar panel 10. The bracket 28 is then secured to a roof hook 24, which is directly screwed onto the rafters 25, ensuring a secure and stable fixation to the roof structure.

[0033] Based on the analysis of the above-mentioned existing solar panel assembly, it is concluded that the traditional solar panel frame is not designed for walking surfaces, and has some limitations in pedestrian walkways or similar applications. The upper flange of the aluminum frame usually extends above the glass, causing the accumulation of water, mud and debris, thereby blocking sunlight and posing a safety risk. The protruding frame is easily damaged by pedestrian traffic, and the traditional design lacks sufficient load-bearing capacity and is prone to cracking under heavy loads. In addition, the method used to protect the traditional solar panel support structure is complex, inefficient in horizontal applications, and does not provide the possibility for non-professional installation, individuals without professional training to effectively and safely assemble and install solar panels.

[0034] The embodiments of the present application will be described in detail below with reference to the accompanying drawings of the embodiments of the present application.

[0035] Please refer to Figures 3-8 , which is a schematic diagram of the overall structure of a solar panel assembly,

[0036] The present embodiment provides a solar panel assembly 20, which comprises a frame 200 and a photovoltaic panel, the frame 200 being arranged around the four sides of the photovoltaic panel for supporting and fixing the photovoltaic panel.

[0037] The frame 200 comprises a supporting bottom and an upper flange 327, the upper flange 327 being arranged on one side of the top of the supporting bottom and being bent towards the opposite side to form a containing space for accommodating the edge of the photovoltaic panel between the supporting top and the bent end of the upper flange 327; the bent end of the upper flange 327 is provided with a contact rim 320.

[0038] The outer wall around the photovoltaic panel is provided with a matching rim 311 matched with the contact rim 320, the contact rim 320 abutting the middle section of the matching rim 311, so that the contact rim 320 does not extend to the top surface of the photovoltaic panel.

[0039] In the following, a solar panel assembly 20 according to the present exemplary embodiment will be further described.

[0040] In some embodiments, referring to Figure 3 The above-mentioned frame 200 comprises a supporting bottom and an upper flange 327, the upper flange 327 being arranged on one side of the top of the supporting bottom and being bent towards the opposite side to form a containing space for accommodating the edge of the photovoltaic panel between the supporting top and the bent end of the upper flange 327; the containing space is used to accommodate the edge of the photovoltaic panel and limit and support the photovoltaic panel.

[0041] In some embodiments, the bent end of the upper flange 327 is provided with a contact edge 320, and the outer wall around the photovoltaic panel is provided with a matching edge 311 matched with the contact edge 320. The contact edge 320 abuts the middle section of the matching edge 311, so that the contact edge 320 does not extend to the top surface of the photovoltaic panel. Through the above design, the upper flange 327 of the frame 200 does not extend to the upper surface of the photovoltaic panel, thereby making the upper surface of the photovoltaic panel free of any obstruction, and improving the photovoltaic efficiency of the photovoltaic panel; and the upper flange 327 of the frame 200 does not cover the photovoltaic panel, which can prevent debris from accumulating on the upper surface of the photovoltaic panel and affecting light absorption; at the same time, a smooth walkable surface is created for the upper surface of the photovoltaic panel, which can reduce the wear and tear on the frame 200 and the shoes when walking.

[0042] As a preferred embodiment, the photovoltaic panel comprises at least one light-transmitting layer 310, a photovoltaic cell, an encapsulant layer 330 and a backsheet 331 stacked in order from top to bottom. The encapsulant layer 330 is composed of two layers of encapsulant material, and is used to encapsulate the photovoltaic cell and the backsheet 331. The light-transmitting layer 310 is located away from the support bottom, and is used to absorb sunlight. The matching edge 311 is arranged on the side wall of the light-transmitting layer 310, mainly because the light-transmitting layer 310 has a relatively large thickness, which can better connect with the frame 200. The photovoltaic cell is not located in the area vertically mapped by the frame 200 and the light-transmitting layer 310, so as to avoid the photovoltaic cell being blocked, and at the same time, the load on the surface can cause micro-cracks in the photovoltaic cell.

[0043] As a preferred embodiment, the matching edge 311 has a first distance D3 between the top surface of the light-transmitting layer 310 and the bottom surface of the light-transmitting layer 310, and the first distance D3 is equal to half of the thickness D2 of the light-transmitting layer 310, so as to provide a proper surface width and better match with the upper flange 327 of the frame 200, while maintaining the necessary physical properties.

[0044] As a preferred embodiment, the matching edge 311 is one of a round chamfer, an inclined chamfer, a single inclined surface, a double inclined surface, a circular arc surface or a curved surface. Specifically, as shown in Figure 8 Figure 8 The matching edge 311 in A is a round chamfer on the upper part of the side wall of the light-transmitting layer 310, which is a smooth circular curved surface. Figure 8 The matching edge 311 in B is a 45-degree single inclined surface of the side wall of the light-transmitting layer 310, and the inclination direction is adapted to the upper flange 327. Figure 8 The matching edge 311 in C has an "S" shape profile on the side wall of the light-transmitting layer 310, which combines concave and convex curves. Figure 8 The matching edge 311 in D is a circular arc surface of the side wall of the light-transmitting layer 310. Figure 8 The matching edge 311 in E is a double inclined surface of the side wall of the light-transmitting layer 310. Figure 8 ​The matching edge 311 in F is a 45-degree bevel on the upper part of the sidewall of the light-transmitting layer 310.

[0045] As a preferred embodiment, refer to Figure 3 The support base includes a vertical plate 328, a first horizontal plate 324 and a second horizontal plate 329, each of which has an inner chamber. The vertical plate 328 is perpendicular to the photovoltaic panel. The first horizontal plate 324 and the second horizontal plate 329 are parallel to the photovoltaic panel and are connected perpendicularly to one side of the vertical plate 328. The first horizontal plate 324 and the second horizontal plate 329 are located at the bottom and top of one side of the vertical plate 328, respectively. The upper flange 327 is connected perpendicularly to the top of the second horizontal plate 329 and away from one side of the vertical plate 328. The vertical plate 328 has a vertical chamber 322, the first horizontal plate 324 has a first horizontal chamber 323, and the second horizontal plate 329 has a second horizontal chamber 321. The first horizontal plate 324 and the first horizontal chamber 323 serve as a platform for clamping the assembly to the base 410, thereby forming a clamping surface. This facilitates the use of simple commercial clips 431 to easily connect to the support structure, simplifies the installation process, reduces the need for specialized tools, and allows flexible installation on various surfaces. The second horizontal plate 329 and the second horizontal chamber 321, in combination with the vertical plate 328 and the vertical chamber, create a wide support surface for the light-transmitting layer 310 along the length D4 to increase its load-bearing capacity, supporting the light-transmitting layer 310 over a wider surface area and increasing the load-bearing capacity of the panel.

[0046] As a preferred embodiment, refer to Figure 3 The third horizontal plate 326 is connected to the side opposite the first horizontal plate 324 of the vertical plate 328. The third horizontal plate 326 helps distribute weight, thereby improving the overall load-bearing capacity and structural integrity of the solar panel assembly 20.

[0047] As a preferred embodiment, the upper flange 327 near the side of the photovoltaic panel is filled with sealant 325, which serves to better connect and fix the light-transmitting layer 310, while protecting the encapsulation material from environmental factors.

[0048] As a preferred embodiment, it further includes an adjustable base 420 and two joists 430 arranged oppositely, with the first horizontal plate 324 connected and fixed to the joists 430 through connectors.

The distance D5 between the solar panel assemblies 20, commonly referred to as the gap, is determined only by the size of the clamps 431 used, and is typically 5-7mm. The joists 430 are supported by adjustable feet, assisted by spacers 421. The entire device is placed on a relatively level surface 410, such as concrete or gravel.
