[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] The following reference Figures 1 to 12 To describe a photovoltaic device 100 provided according to some embodiments of the present invention.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the present invention proposes a photovoltaic device 100, which includes: a photovoltaic element 110; a junction box 120 disposed on the photovoltaic element 110, the junction box 120 including a first housing 122, a second housing 130 and a wire 132, at least a portion of the first housing 122 being located on one side of the photovoltaic element 110, at least a portion of the second housing 130 being located on the other side of the photovoltaic element 110, the wire 132 being fixed to the first housing 122 or the second housing 130, the side of the first housing 122 facing away from the second housing 130 having a groove 124; and a sunlight indicator 140, at least a portion of the sunlight indicator 140 being disposed in the groove 124.

[0038] The photovoltaic device 100 proposed in this utility model includes a photovoltaic element 110, a junction box 120, and a sunlight indicator 140. The junction box 120 is disposed on the photovoltaic element 110, and the sunlight indicator 140 is disposed on the junction box 120. That is, the sunlight indicator 140 is no longer disposed on the photovoltaic element 110, thereby avoiding the occupation of space on the photovoltaic element 110 by the sunlight indicator 140, facilitating the storage of the photovoltaic device 100, and allowing for a larger area to be arranged for components such as solar panels, which is beneficial to improving the power generation efficiency of the photovoltaic device 100.

[0039] Junction box 120 includes a first housing 122, a second housing 130, and a wire 132. At least a portion of the first housing 122 is located on one side of the photovoltaic element 110, and at least a portion of the second housing 130 is located on the other side of the photovoltaic element 110. The first housing 122 and the second housing 130 are directly or indirectly connected to fix them to the photovoltaic element 110. The first housing 122 and the second housing 130 are clamped on the photovoltaic element 110. The wire 132 is fixed to the first housing 122 or the second housing 130, and the wire 132 is electrically connected to the photovoltaic element 110 to output electrical energy.

[0040] The first housing 122 has a groove 124 on the side opposite to the second housing 130. At least a portion of the sunlight indicator 140 is disposed in the groove 124, thereby reducing the height of the sunlight indicator 140 protruding from the first housing 122 and further reducing the space occupied by the sunlight indicator 140, making it easier to store the photovoltaic device 100.

[0041] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the groove 124 includes a first groove 126, and the sunlight indicator 140 includes: an indicator disk 142 disposed in the first housing 122, the indicator disk 142 being located within the first groove 126; and a lens 146 disposed in the first housing 122, the lens 146 being disposed outside the first groove 126, the lens 146 including a light-transmitting portion 148 and a light-blocking portion 150, the indicator disk 142 being opposite to both the light-transmitting portion 148 and the light-blocking portion 150.

[0042] In this embodiment, the groove 124 includes a first groove 126, and the first housing 122 is provided with the first groove 126 on the side opposite to the second housing 130.

[0043] The sunlight indicator 140 includes an indicator disc 142 and a lens 146. The lens 146 is separate from the indicator part 144. The indicator disc 142 is disposed in a first groove 126, and the lens 146 is disposed on the side of the indicator disc 142 away from the bottom of the first groove 126, thereby separating the indicator disc 142 and the lens 146. After sunlight shines on the lens 146, it then shines on the indicator disc 142.

[0044] The indicator disc 142 is disposed within the first groove 126 and fixed to the first housing 122. The lens 146 is disposed outside the first groove 126 and fixed to the first housing 122, such that the lens 146 is located on the side of the indicator disc 142 opposite to the bottom of the first groove 126. The indicator disc 142 can be adhesively attached to the first housing 122, or it can be fixed to the first housing 122 by means of clips or bolts. Similarly, the lens 146 can be adhesively attached to the first housing 122, or it can be fixed to the first housing 122 by means of clips or bolts.

[0045] The lens 146 includes a light-transmitting part 148 and a light-shielding part 150. The indicator 142 is disposed opposite to the light-transmitting part 148 and the light-shielding part 150. When sunlight shines on the lens 146, the sunlight can pass through the light-transmitting part 148 and form a light spot on the indicator 142. Due to different angles of sunlight, the position of the light spot on the indicator 142 is also different. The current angle of sunlight can be determined by the position of the light spot on the indicator 142, thereby facilitating the adjustment of the photovoltaic element 110 and improving the power generation efficiency of the photovoltaic device 100.

[0046] Furthermore, the arrangement of the light-transmitting part 148 and the light-shielding part 150 makes the shape of the light spot easier to distinguish, and the light-shielding part 150 can form a projection point, making it easier to observe the position of the light spot and the position of the projection point, thus making the sunlight indicator 140 easier to use.

[0047] The light-shielding part 150 can be formed by screen printing, ink, or opaque components.

[0048] The lens 146 can be made of glass or plastic, and the indicator 144 can be made of glass, plastic, or metal, etc.

[0049] like Figure 3 , Figure 4 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments, optionally, the indicator disk 142 has a circular structure, the light-transmitting part 148 has a circular structure, and the light-transmitting part 148 is arranged around the light-blocking part 150; the indicator disk 142 includes a plurality of indicator parts 144, which are arranged sequentially from the inside to the outside.

[0050] In this embodiment, the indicator 142 has a circular structure and the light-transmitting part 148 has a circular structure. The indicator 142 and the light-transmitting part 148 are opposite to each other, so that the light spot or projection point formed on the indicator 142 by sunlight passing through the light-transmitting part 148 matches the indicator 142, making it easier for the user to observe the position of the light spot or projection point.

[0051] The light-transmitting part 148 is arranged around the light-blocking part 150, so that a projection point without light can be formed at the center of the light spot. The indicator disk 142 includes a plurality of indicator parts 144, which are arranged in sequence from the inside to the outside. That is, the middle area of ​​the indicator part 144 forms a solid part, and on the outside of the solid part, there are ring-shaped parts arranged in sequence.

[0052] Furthermore, the outer ring of the indicator 144 can be a circular structure, that is, the innermost indicator 144 is a circular structure, and the outer indicator 144 outside the innermost indicator 144 are all circular ring structures, so that one layer of indicator 144 is nested on the outer side of the other side of the indicator 144, forming a nested structure.

[0053] The indicator 144 can be formed by components such as screen printing or ink, and adjacent indicator 144s have different colors, which makes it easier to observe the position of the light spot or projection point.

[0054] When sunlight shines on the lens 146, it passes through the light-transmitting part 148 and the light-blocking part 150, forming a ring-shaped light spot on the indicator 142, which has two edges: an inner circle and an outer circle. The inner circle of the light spot is the edge of the projection point. The inner and outer circles of the light spot can then be displayed on the indicator 144, thereby allowing for a more accurate determination of the angle of sunlight.

[0055] For example, if the inner circle of the light spot is located within only one indicator 144, and the outer circle of the light spot is located within the same indicator 144 or another indicator 144, it indicates that the current sunlight is roughly perpendicular; if the inner circle of the light spot is located within two or more indicator 144, or the outer circle of the light spot is located within two or more indicator 144, it indicates that the current sunlight is not roughly perpendicular.

[0056] Alternatively, the indicator 144 projected onto the inner circle of the light spot can be used to determine whether the sunlight is shining perpendicularly. That is, if the inner circle of the light spot is projected onto the indicator 144 at the very center, or if the inner circle of the light spot and the indicator 144 at the very center are approximately concentric, it indicates that the sunlight is shining perpendicularly.

[0057] Of course, the specific indication method of the sunlight indicator 140 can also be achieved by setting a scale, etc. The above indication method of sunlight angle is only for explanation.

[0058] like Figure 3 and Figure 4 As shown, in some embodiments, the groove 124 may optionally include a second groove 128, with the first groove 126 located at the bottom of the second groove 128, and the lens 146 disposed within the second groove 128.

[0059] In this embodiment, the groove 124 further includes a second groove 128, that is, the first housing 122 also includes a second groove 128. The first groove 126 is disposed at the bottom of the second groove 128, thereby forming a stepped structure with the first groove 126 and the second groove 128. The indicator part 144 is disposed in the first groove 126, and the lens 146 is disposed in the second groove 128. Furthermore, the lens 146 and the indicator part 144 are separated, thereby providing a longer path for sunlight and making it easier to judge the angle of sunlight. In addition, by setting the second groove 128, the sunlight indicator 140 can be completely embedded in the first housing 122, thereby further reducing the space occupied by the sunlight indicator 140 and making it easier to store the photovoltaic device 100.

[0060] like Figure 3 and Figure 4 As shown, in some embodiments, the light-transmitting portion 148 and the first groove 126 are optionally disposed opposite to each other.

[0061] In this embodiment, the light-transmitting portion 148 and the first groove 126 are arranged opposite to each other, thereby ensuring that sunlight can shine on the indicator disk 142 in the first groove 126 through the light-transmitting portion 148, thereby ensuring the indication effect of the sunlight angle.

[0062] like Figure 2 As shown, in some embodiments, optionally, the photovoltaic element 110 includes a first through hole 112, a protrusion 129 is provided on the side of the first housing 122 facing the second housing 130, a first groove 126 is located on the side of the protrusion 129 away from the second housing 130, and the protrusion 129 passes through the first through hole 112.

[0063] In this embodiment, the photovoltaic element 110 includes a first through hole 112. A protrusion 129 is provided on the side of the first housing 122 facing the second housing 130. A first groove 126 is provided in the protrusion 129. The first groove 126 is provided on the side of the protrusion 129 facing away from the second housing 130. The protrusion 129 passes through the first through hole 112. That is, the protrusion 129 passes through the first through hole 112 of the photovoltaic element 110, thereby reducing the protrusion height of the first housing 122 relative to the photovoltaic element 110, thereby reducing the space occupied by the first housing 122 and facilitating the storage of the photovoltaic device 100.

[0064] The protrusion 129 can be a cylindrical structure or a polygonal columnar structure, etc.

[0065] Furthermore, the protrusion 129 can extend into the second housing 130, or only into the first through hole 112 of the photovoltaic element 110.

[0066] like Figure 2As shown, in some embodiments, the photovoltaic element 110 optionally includes a second through hole 114, and the photovoltaic device 100 also includes a screw 160 that passes through the second through hole 114 and connects the first housing 122 and the second housing 130.

[0067] In this embodiment, the photovoltaic element 110 includes a second through hole 114, and the photovoltaic device 100 also includes a screw 160. The screw 160 passes through the second through hole 114 and connects the first housing 122 and the second housing 130, thereby realizing the fixed connection of the photovoltaic element 110, the first housing 122 and the second housing 130.

[0068] Alternatively, a threaded hole can be provided in the first housing 122, and a screw 160 can pass through the second housing 130 and the photovoltaic element 110, and be connected to the first housing 122 through the threaded hole.

[0069] like Figure 2 , Figure 5 and Figure 7 As shown, in some embodiments, optionally, the lens 146 covers the screw 160, and the lens 146 also includes a shielding portion 152, which is opposite to the screw 160.

[0070] In this embodiment, the lens 146 covers the screw 160. The lens 146 also includes a shielding part 152, which is opposite to the screw 160. The shielding part 152 shields the screw 160, making the screw 160 invisible from the outside and improving the aesthetics of the photovoltaic device 100.

[0071] The shielding portion 152 can be formed by screen printing, ink, or opaque components.

[0072] like Figure 2 As shown, in some embodiments, optionally, at least a portion of the first housing 122 is located on the sun-facing side 116 of the photovoltaic element 110.

[0073] In this embodiment, at least a portion of the first housing 122 is located on the sun-facing side 116 of the photovoltaic element 110, and the sunlight indicator 140 is located on the sun-facing side 116 of the photovoltaic element 110, so that the sunlight indicator 140 can indicate the angle of sunlight on the sun-facing side 116 of the photovoltaic element 110, which is convenient for user operation.

[0074] like Figure 1 and Figure 2 As shown, in some embodiments, the junction box 120 is optionally located at the edge of the photovoltaic element 110.

[0075] In this embodiment, the junction box 120 is located at the edge of the photovoltaic element 110, thereby reducing the space occupied by the junction box 120 on the photovoltaic element 110 and ensuring that the photovoltaic element 110 can be equipped with a large area of ​​solar panels.

[0076] like Figure 1 As shown, in some embodiments, the photovoltaic device 100 may optionally include a bracket 170, to which the photovoltaic element 110 is movably connected.

[0077] In this embodiment, the photovoltaic device 100 further includes a bracket 170, and the photovoltaic element 110 is movably connected to the bracket 170 to facilitate adjustment of the angle of the photovoltaic element 110. The photovoltaic element 110 and the bracket 170 can be connected via components such as hinges or universal joints.

[0078] like Figure 2 As shown, in some embodiments, optionally, a protective element 180 is provided on the wire 132, the protective element 180 being used for waterproofing and / or dustproofing of the wire 132, etc.

[0079] The photovoltaic device 100 provided by this utility model includes a photovoltaic element 110, a junction box 120, and a sunlight indicator 140. The sunlight indicator 140 uses sunlight to illuminate the light-blocking part 150 at the center of the lens 146, which is opaque, and the resulting shadow is projected onto the indicator disk 142. The indicator disk 142 is silkscreened with rings of different colors and sizes. Users can distinguish and adjust the angle of the photovoltaic element 110 by observing the position of the projected shadow. It is best if the projection point coincides with the central indicator part 144, thereby improving the power generation efficiency of the photovoltaic device 100.

[0080] The lens 146 and the indicator dial 142 are respectively installed at different height positions of the first housing 122 in order to better form and observe the projection point.
