Description
-1- Photovoltaic Module Frame
[01] The present disclosure relates to a photovoltaic module frame.
[02] In recent years, due to the year-by-year decrease in crude oil stocks around the world, energy issues have become the focus of global attention. In order to resolve the crisis of energy depletion, the research and development of various alternative energy sources has indeed become a top priority. With the rising awareness of environmental protection, together with the advantage of zero pollution that solar energy has, solar energy has become the most attention-grabbing focus in related fields.
[03] Common photovoltaic module frames are mostly made by using metal casting.
Owing to the problem of corrosion, the current photovoltaic power generation equipment is not suitable for being installed in coastal areas, which greatly reduces the durability and application flexibility.
[04] One aspect of the present disclosure provides a photovoltaic module frame.
[05] A photovoltaic module frame is provided. The photovoltaic module frame includes a first vertical board, a first horizontal board, a second horizontal board, a third horizontal board, and a second vertical board. The first horizontal board adjoins one end of a sidewall of the first vertical board. The second horizontal board adjoins the sidewall of the first vertical board and is located below the first horizontal board, and is configured to clamp a photovoltaic module with the first horizontal board. The third horizontal board adjoins another end of the sidewall of the first vertical board and is located below the second horizontal board. The second vertical board is parallel to the first vertical board, and two ends of the second vertical board respectively adjoin the second horizontal board and the third horizontal board. The first vertical board, the second vertical board, the first horizontal board, the second horizontal board, and the third horizontal board are integrally formed as a single piece, and the first vertical board, the second vertical board, the first horizontal board, the second horizontal board, and the third horizontal board include a plastic material or a composite material.
[06] In the foregoing, the plastic material of the photovoltaic module frame includes polyvinyl chloride, polyethylene terephthalate, polycarbonate, polybutylene terephthalate, polyphenylene sulfide, polyether sulfone, polyamide, or combinations thereof.
[07] In the foregoing, the composite material of the photovoltaic module frame includes polyvinyl chloride with a glass fiber, polyethylene terephthalate with a glass fiber, 40 polycarbonate with a glass fiber, polybutylene terephthalate with a glass fiber,
-2- polyphenylene sulfide with a glass fiber, polyether sulfone with a glass fiber, polyamide with a glass fiber, or combinations thereof.
[08] In the foregoing, each of the first vertical board, the second vertical board, the first horizontal board, the second horizontal board, and the third horizontal board of the photovoltaic module frame further includes a weather-resistance additive.
[09] In the foregoing, the first horizontal board of the photovoltaic module frame has a bottom surface, the bottom surface inclines downwards.
[10] In the foregoing, the bottom surface of the first horizontal board of the photovoltaic module frame has a groove.
[11] In the foregoing, the bottom surface of the first horizontal board of the photovoltaic module frame has a sawtooth structure.
[12] In the foregoing, the second horizontal board of the photovoltaic module frame has a top surface, the top surface inclines upwards.
[13] In the foregoing, the top surface of the second horizontal board of the photovoltaic module frame has a sawtooth structure.
[14] In the foregoing, the first horizontal board of the photovoltaic module frame has a top surface, the top surface has an anti-slip pattern.
[15] According to the embodiments of the present disclosure, due to the plastic material and composite material included in the photovoltaic module frame, the weather resistance of the frame and the durability of the frame in the coastal area can be increased, and the strength of the frame is not affected by erosion. Different from the phenomenon in which the corrosion is accelerated after the metal surface protective layer of the traditional frame is worn away, the photovoltaic module frame according to the present disclosure is completely insulated, and there is no potential difference between the photovoltaic module, fasteners, and bracket because of heterogeneous metals. Additionally, the photovoltaic module frame has the advantage of light weight due to its materials, and the construction process when the photovoltaic module frame and the photovoltaic module are mounted is the same as the traditional method, which can reduce the construction cost.
[16] lt is to be understood that both the foregoing general description and the following detailed description are by examples, and are intended to provide further explanation of the disclosure as claimed.
[17] The disclosure can be more fully understood by reading the following detailed description of the embodiments, with reference made to the accompanying drawings as follows:
[18] Fig. 1 depicts a cross-sectional view of a photovoltaic module frame according to one embodiment of the present disclosure.
[19] Fig. 2 depicts a cross-sectional view of the photovoltaic module frame in Fig. 1 40 when being mounted on a photovoltaic module.

[20] Fig. 3 depicts a cross-sectional view of a photovoltaic module frame according to another embodiment of the present disclosure.
[21] Fig. 4 depicts a cross-sectional view of a photovoltaic module frame according to still another embodiment of the present disclosure.
[22] In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. lt will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and components are schematically depicted in order to simplify the drawings.
[23] Fig. 1 depicts a cross-sectional view of a photovoltaic module frame 100 according to one embodiment of the present disclosure. Fig. 2 depicts a cross-sectional view of the photovoltaic module frame 100 in Fig. 1 when being mounted on a photovoltaic module C. A description is provided with reference to Fig. 1 and Fig. 2. The photovoltaic module frame 100 includes a first vertical board 110, a second vertical board 120, a first horizontal board 130, a second horizontal board 140, and a third horizontal board 150. The first horizontal board 130 adjoins one end {such as an upper end) of a sidewall of the first vertical board 110. The second horizontal board 140 adjoins the sidewall of the first vertical board 110 and is located below the first horizontal board 130. When the photovoltaic module frame 100 is used, the second horizontal board 140 is configured to clamp the photovoltaic module C with the first horizontal board 130. The third horizontal board 150 adjoins another end (such as a lower end) of the sidewall of the first vertical board 110 and is located below the second horizontal board 140. That is to say, the second horizontal board 140 is located between the first horizontal board 130 and the third horizontal board 150. The second vertical board 120 is approximately parallel to the first vertical board 110, and two ends of the second vertical board 120 respectively adjoin the second horizontal board 140 and the third horizontal board 150. The second vertical board 120 extends from the second horizontal board 140 to the third horizontal board 150.
[24] Each of the first vertical board 110, the second vertical board 120, the first horizontal board 130, the second horizontal board 140, and the third horizontal board 150 is made of a plastic material or a composite material. The first vertical board 110, the second vertical board 120, the first horizontal board 130, the second horizontal board 140, and the third horizontal board 150 may be integrally formed as a single piece, such as plastic injection molding, but the present disclosure is not limited in this regard. The above plastic material may include polyvinyl chloride (PVC), polyethylene terephthalate (PET), polycarbonate (PC), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), polyether sulfone (PES), polyamide (PA), or combinations thereof. The polyamide includes PA4, PA46, PAS, PAGS, PAST, PAST, PA610, PA812, PA10T, and PA11T.
40 [25] The above composite material may include polyvinyl chloride (PVC) with a glass
-4- fiber, polyethylene terephthalate (PET) with a glass fiber, polycarbonate (PC) with a glass fiber, polybutylene terephthalate (PBT) with a glass fiber, polyphenylene sulfide (PPS) with a glass fiber, polyether sulfone (PES) with a glass fiber, polyamide (PA) with a glass fiber, or combinations thereof. The polyamide includes PA4, PA46, PAG, PAGS, PAST, PAST, PAB10, PA612, PA10T, and PA11T.
[26] In addition, no matter whether it is the plastic material or the composite material, a weather-resistance additive can be further added, so that each of the first vertical board 110, the second vertical board 120, the first horizontal board 130, the second horizontal board 140, and the third horizontal board 150 of the photovoltaic module frame 100 includes the weather-resistance additive.
[27] When the photovoltaic module C is installed in a coastal area, the salt in the sea water frequently accelerates the corrosion of the frame of a traditional metal photovoltaic module. Due to the plastic material and composite material included in the photovoltaic module frame 100, the weather resistance of the frame and the durability of the frame in the coastal area can be increased, and the strength of the frame is not affected by erosion. Different from the phenomenon in which the corrosion is accelerated after the metal surface protective layer of the traditional frame is worn away, the photovoltaic module frame 100 according to the present disclosure is completely insulated, and there is no potential difference between the photovoltaic module C, fasteners, and a bracket because of heterogeneous metals. Additionally, the photovoltaic module frame 100 has the advantage of light weight due to its materials, and the construction process when the photovoltaic module frame 100 and the photovoltaic module C are mounted is the same as the traditional method, which can reduce the construction cost. In addition to that, after changing to the plastic material or the composite material, not only can the problem of corrosion be avoided, but a grounding process can also be further omitted to save a lot of grounding wires and the cost of grounding process.
[28] In the present embodiment, a bottom surface 132 of the first horizontal board 130 inclines downwards, and a top surface 141 of the second horizontal board 140 inclines upwards. Since the photovoltaic module frame 100 is flexible due to its material characteristics, the above inclined design of the first horizontal board 130 and the second horizontal board 140 can clamp the photovoltaic module C more firmly. The photovoltaic module C and the frame may be combined by first using a double-sided tape to seal a periphery of the photovoltaic module C, and then placing the photovoltaic module C between the first horizontal board 130 and the second horizontal board 140 of the photovoltaic module frame 100. Or, the photovoltaic module C is inserted after silicone glue is applied between the first horizontal board 130 and the second horizontal board 140 of the photovoltaic module frame 100.
[29] In addition, a top surface 131 of the first horizontal board 130 has an anti-slip pattern 170. In the subsequent processes, the photovoltaic module frame 100 is locked to 40 some other component(s) on it, and the disposition of the anti-slip pattern 170 can effectively

increase a friction force between the photovoltaic module frame 100 and the some other component(s).
[30] It should be understood that the connection relationships, materials, and effects of the components that have been described will not be repeated. In the following description, other types of photovoltaic module frames are illustrated.
[31] Fig. 3 depicts a cross-sectional view of a photovoltaic module frame 100A according to another embodiment of the present disclosure. The photovoltaic module frame 100A includes the first vertical board 110, the second vertical board 120, a first horizontal board 130A, the second horizontal board 140, and the third horizontal board 150. Different from the embodiment of Fig. 1, a bottom surface 132A of the first horizontal board 130A of the photovoltaic module frame 100A further has a groove 180. When the photovoltaic module frame 100A is used to clamp the photovoltaic module C of Fig. 2, silicone glue is first applied to a clamping position. When the photovoltaic module C enters, the silicone glue will enter the groove 180 of the first horizontal board 130A, which can significantly reduce the amount of silicone glue overflowing the outer frame. The groove 180 may be called a glue stop groove.
[32] Fig. 4 depicts a cross-sectional view of a photovoltaic module frame 100B according to still another embodiment of the present disclosure. As shown in the figure, the photovoltaic module frame 100B includes a first vertical board 110A, the second vertical board 120, a first horizontal board 130B, a second horizontal board 140A, and the third horizontal board 150. Different from the embodiment of Fig. 1, each of a bottom surface 132B of the first horizontal board 130B and a top surface 141A of the second horizontal board 140A of the photovoltaic module frame 100B has a sawtooth structure 160. When the photovoltaic module frame 100A is used to clamp the photovoltaic module C of Fig. 2, the sawtooth structures 160 can increase a friction force between the photovoltaic module frame 100B and the photovoltaic module C so that the clamping is firmer.
[33] Additionally, in the present embodiment, the first vertical board 110A of the photovoltaic module frame 100B has a thickness greater than that of the first vertical board 110 in Fig. 1 and Fig. 2 to further improve the structural strength and bearing capacity.
[34] The improved photovoltaic module frame with the new material(s) can not only meet the needs of upgrading weather resistance and durability, but can also resolve the problem of metal corrosion. As a result, it can be used in coastal areas. At the same time, the light weight of the photovoltaic frame is more advantageous for manufacturing and transportation. The photovoltaic module frame according to the present disclosure can be used with the installation components of the traditional photovoltaic modules, and no additional burden is added to the construction process.
[35] Since the aforementioned photovoltaic module frames 100, 100A, and 100B are made of the composite material including polyamide (i.e., Nylon), lifespan can be extended to at least 20 years for the consideration of durability, metal corrosion, and strong wind in 40 coastal areas. In addition, the materials of the photovoltaic module frames 100, 100A, and
-6- 100B can be recycled to prevent pollution. The composite material of the aforementioned photovoltaic module frames 100, 100A, and 100B is betterthan PVC and PET. For example, PVC is too soft and cannot be mixed with glass fiber to strengthen structure. If a photovoltaic module frame made of PVC is manufactured by extrusion, it would deform during the extrusion. The strength of the photovoltaic module frame made of PVC is not enough to be a frame of a solar cell. If a photovoltaic module frame is made of PET, the photovoltaic module frame would be brittle and hydrolyzed under high temperature and humidity. In addition, the product yield for the photovoltaic module frame made of in the extrusion is bad.
[36] Nylon has a saturation point of water absorption, so the composite material including polyamide does not get worse after using for a period of time. The glass fiber is added in the composite material to increase rigidity and strength, and an anti-UV additive (to be described hereinafter) can be further added in response to outdoor environment. The composite material may be melted in an extrusion tool to form the photovoltaic module frame through extrusion.
[37] In some embodiments, each of the aforementioned photovoltaic module frames 100, 100A, and 100B may be made of a composite material including polyamide with a glass fiber, and further including cyclohexanedicarboxylic acid (CHDA). The composite material including CHDA is configured to prevent absorbing ultraviolet (UV) light, such as a wavelength of UV light in a range from 290 nm to 320 nm. As a result, a photosensitivity wavelength of each of the photovoltaic module frames 100, 100A, and 100B can be changed to decrease the formation of free radical groups, thereby improving weather resistance and durability. Moreover, CHDA in the photovoltaic module frames 100, 100A, and 100B is a rigid and flexible structure, which improves the weather resistance and solves the problems of insufficient strength, poor processability, and easy moisture absorption.
[38] In some embodiments, if the aforementioned photovoltaic module frames 100, 100A, and 100B made of the composite material including polyamide, CHDA, and the glass fiber, a specific gravity of the composite material can be smaller than or equal to 1.47, a tensile strength of the composite material can be greater than or equal to 170 MPa, a Rockwell hardness of the composite material can be greater than or equal to 110. In addition, a proportion by weight of CHDA and polyamide in the composite material may be smaller than 70%, such as 60%, and a proportion by weight of the glass fiber in the composite material may be greater than 30%, such as 40%. Through such a configuration, the above properties and advantages of photovoltaic module frames 100, 100A, and 100B can be achieved.
