[0020] Compared with the prior art, the photovoltaic module of this utility model has the following advantages:

[0021] 1. The photovoltaic module of this utility model includes a photovoltaic panel and a base plate. The photovoltaic panel includes a mounting frame and photovoltaic modules mounted on the mounting frame. The base plate includes a frame and a color steel plate covering the bottom wall of the base plate. The photovoltaic panel is connected to the frame at the connecting edge of the frame, and the photovoltaic panel has two working states: the photovoltaic panel is housed in the space formed by the color steel plate and the frame, working in a flat state; or it forms an angle with the base plate, working in an inclined state. The bottom wall of the base plate is provided with support columns. In the flat state, the photovoltaic panel abuts against the support columns and leaves a gap between it and the color steel plate. By abutting the photovoltaic panel with the support columns, a gap equal to the height of the support columns is left between the bottom of the photovoltaic panel and the color steel plate, which facilitates heat dissipation of the photovoltaic panel in the flat state, avoiding excessive internal temperature of the photovoltaic panel that affects working efficiency and service life. At the same time, the support columns play a role in stabilizing the photovoltaic panel during the transportation of the photovoltaic module, thereby avoiding accidental damage caused by collision between the photovoltaic panel and the color steel plate, reducing transportation and installation costs, and improving project efficiency.

[0022] 2. The mounting frame of this utility model has a limiting groove corresponding to the support column, and the limiting groove partially accommodates the top of the support column. By accommodating the top of the support column in the limiting groove, the photovoltaic panel's sway is restricted during the use, storage, and transportation of the photovoltaic module. This prevents the support column from bumping or scratching the photovoltaic panel due to relative movement between the support column and the photovoltaic panel, thereby improving the service life of the photovoltaic panel.

[0023] 3. At least one hinge is provided at the end of the connecting edge away from the bottom wall of the base plate in this utility model. The photovoltaic panel is connected to the connecting edge through the hinge and can rotate in the direction of hinge rotation. By providing a hinge on the connecting edge, the rotation of the photovoltaic panel relative to the base plate is more effortless and convenient, facilitating the switching of the photovoltaic panel to different working states and improving the usability of the photovoltaic module.

[0024] 4. The base plate of this utility model includes a bracket. A rotating shaft connected to the bracket is provided on the side of the frame away from the connecting edge. The bracket can rotate along the rotation direction of the rotating shaft. When the photovoltaic panel is working in an inclined state, the bracket abuts against the mounting frame and supports the photovoltaic panel to maintain its inclination. By setting the bracket abutting against the mounting frame, the angle between the photovoltaic panel and the base plate in the inclined state is fixed, preventing the photovoltaic panel from falling due to gravity and reducing the angle between the photovoltaic panel and the base plate in the inclined state, thereby affecting the photovoltaic panel's light energy reception efficiency. By setting the rotating shaft, the bracket and the base plate are integrated into one piece, and the storage and support states can be switched by rotation, which facilitates the installation of the photovoltaic module and the switching of the working mode, greatly improving the ease of use of the photovoltaic module.

[0025] 5. The mounting frame of this utility model has a bracket storage groove corresponding to the bracket. When the photovoltaic panel is tilted, the end of the bracket away from the pivot is engaged with the end of the bracket storage groove away from the connecting edge. When the photovoltaic panel is laid flat, the bracket is stored in the bracket storage groove. The bracket storage groove accommodates the bracket in its flat state, preventing damage to the photovoltaic panel and its components during transportation. It also further limits the relative movement between the end of the bracket away from the pivot and the mounting frame in the tilted state, greatly enhancing the tightness of the connection between the bracket and the photovoltaic panel and improving the functional stability of the photovoltaic module.

[0026] 6. The mounting frame of this utility model also includes fixing components. At least one fixing component is provided on each side of each photovoltaic module, and the fixing component is snapped into the side of the photovoltaic module. By fixing the photovoltaic module with the fixing component, the fixing strength of the photovoltaic module on the mounting frame is strengthened, and the stability of the photovoltaic panel structure is improved.

[0027] 7. An inverter is provided on the side of the photovoltaic panel closest to the base plate of this utility model. Through the inverter installed on the photovoltaic panel, the direct current converted from solar energy by the photovoltaic module can be converted into alternating current, which is convenient for direct use in residential homes. This reduces the secondary power conversion process required by users before connecting the photovoltaic module to their homes and improves the practicality of the photovoltaic module.

[0028] 8. The base plate of this utility model has at least one drainage groove along the frame; the frame also includes frame corners at the four corners, with drainage holes on the surfaces corresponding to both ends of each drainage groove. By opening the drainage grooves and the drainage holes corresponding to both ends of the drainage grooves, the water accumulated on the photovoltaic panel after rainfall can flow into the drainage grooves in a timely manner, and finally flow through the drainage holes to be discharged to the outside of the photovoltaic module. This avoids the situation where water accumulated near the connection edge of the photovoltaic panel cannot be discharged after rainfall due to the obstruction of the frame, forming a water accumulation band, which would affect the local dust accumulation of the photovoltaic module and affect the light energy conversion efficiency. This greatly improves the functional stability and working efficiency of the photovoltaic module.

[0029] 9. At least one connecting hole is provided on the side of the frame corner connected to the adjacent side of the connecting edge of this utility model. By providing the connecting hole, when multiple photovoltaic modules need to be spliced ​​together, two adjacent photovoltaic modules can be aligned and connected through the connecting hole, thereby achieving an integrated effect and improving the practicality of the photovoltaic modules.

[0030] 10. The frame of this utility model has handles on both adjacent sides of the connecting edge. By providing handles on both sides of the frame, it is convenient for users to lift and move the photovoltaic module during installation or use, thus improving the ease of use of the photovoltaic module.

[0047] Please see Figures 1-4 The first embodiment of this utility model provides a photovoltaic module 1, including a photovoltaic panel 2 and a base plate 3. The photovoltaic panel 2 includes a mounting frame 22 and a photovoltaic module 21 mounted on the mounting frame 22. The base plate 3 includes a frame 35 and a color steel plate 31 covering the bottom wall of the base plate 3. The photovoltaic panel 2 is connected to the frame 35 at the connecting edge 351 of the frame 35. The photovoltaic panel 2 has two working states: the photovoltaic panel 2 is housed in the space formed by the color steel plate 31 and the frame 35 and works in a flat state; or it forms an angle with the base plate 3 and works in an inclined state. The bottom wall of the base plate 3 is provided with a support column 32. In the flat state, the photovoltaic panel 2 abuts against the support column 32 and leaves a gap between it and the color steel plate 31.

[0048] Specifically, the height of the photovoltaic panel 2, which is supported by the support column 32, is no higher than the height of the frame 35.

[0049] More specifically, in this embodiment, the photovoltaic modules 21 are installed vertically on the mounting frame 22, which is more suitable for distributed rooftop use scenarios where the surrounding area is shaded.

[0050] More specifically, the length of the connecting edge 351 and its opposite edge ranges from 4000mm to 8000mm, and the length of the two adjacent edges of the connecting edge 351 ranges from 2000mm to 4000mm; in the frame 35 of this embodiment, the length of the connecting edge 351 and its opposite edge is 6000mm, and the length of the two adjacent edges of the connecting edge 351 is 3000mm.

[0051] Understandably, when the photovoltaic panel 2 is working in a flat state, the support column 32 abuts against the photovoltaic panel 2 and the gap left allows the photovoltaic panel 2 to dissipate heat during operation, thereby avoiding excessive internal working temperature of the photovoltaic panel 2, which would affect working efficiency and service life.

[0052] Understandably, the support column 32 also avoids direct contact between the photovoltaic panel 2 and the color steel plate 31, preventing accidental damage caused by collisions between the photovoltaic panel 2 and the color steel plate 31, and plays a role in stabilizing the photovoltaic panel 2 during the transportation of the photovoltaic module 1.

[0053] Furthermore, the mounting frame 22 has a limiting groove 221 corresponding to the support column 32, and the limiting groove 221 partially accommodates the top of the support column 32.

[0054] Understandably, the fitting of the limiting groove 221 and the support column 32 hinders the relative movement of the support column 32, effectively preventing the support column 32 from bumping or scratching the photovoltaic panel 2 during use or transportation, thus avoiding the shortening of the service life of the photovoltaic panel 2.

[0055] Understandably, the limiting groove 221 increases the vertical distance between the top of the photovoltaic panel 2 and the top of the frame 35 while maintaining the same gap height between the support column 32 and the photovoltaic panel 2, thereby further preventing accidental collisions of the photovoltaic panel 2 when multiple photovoltaic modules 1 are stacked and transported.

[0056] Furthermore, at least one hinge 353 is provided at the end of the connecting edge 351 away from the bottom wall of the base plate 3. The photovoltaic panel 2 is connected to the connecting edge 351 through the hinge 353 and can rotate in the rotation direction of the hinge 353.

[0057] Specifically, in this embodiment, four hinges 353 are provided on the connecting edge 351 to connect with the photovoltaic panel 2.

[0058] Understandably, the hinge 353 facilitates the rotation of the photovoltaic panel 2 relative to the base plate 3, allowing the photovoltaic panel 2 to be more easily and conveniently stored in the space formed by the frame 35 and the color steel plate 31 or opened at a certain angle, making it easier for the photovoltaic panel 2 to switch between two different working states and greatly improving the usability of the photovoltaic module.

[0059] Furthermore, the base plate 3 includes a bracket 33, and a rotating shaft 352 connected to the bracket 33 is provided on the side of the frame 35 away from the connecting edge 351. The bracket 33 can rotate along the rotation direction of the rotating shaft 352. When the photovoltaic panel 2 is working in an inclined state, the bracket 33 abuts against the mounting frame 22 and supports the photovoltaic panel 2 to maintain a fixed tilt angle.

[0060] Specifically, in this embodiment, the base plate 3 includes four brackets 33 that abut against and support the photovoltaic panel 2, and the frame 35 is provided with four rotating shafts 352 that are connected to the brackets 33.

[0061] More specifically, in this embodiment, the angle between the photovoltaic panel 2 and the base plate 3 in the tilted state is 50°.

[0062] Understandably, the abutment relationship between the bracket 33 and the mounting frame 22 effectively prevents the photovoltaic panel 2 from falling due to gravity when it is working in an inclined state. It supports and prevents the photovoltaic panel 2 from falling and causing the angle between it and the base plate 3 to decrease, thereby maintaining the angle between the photovoltaic panel 2 and the base plate 3 at an angle that is conducive to the photovoltaic panel 2 receiving light energy, and greatly improving the working efficiency of the photovoltaic module 1.

[0063] Understandably, through the connection between the pivot 352 and the bracket 33, the bracket 33 can rotate around the pivot 352 as the center, thereby choosing to support the bracket 33 or store it between the frame 35, which facilitates the switching of the photovoltaic panel 2 between the two working modes; in addition, the setting of the pivot 352 integrates the bracket 33 and the base plate 3 into one piece, which makes it convenient for users to complete the installation without configuring the bracket 33 separately after purchasing the product, greatly improving the ease of use of the photovoltaic module 1.

[0064] Furthermore, the mounting frame 22 has a bracket storage groove 223 corresponding to the bracket 33; when the photovoltaic panel 2 is in an inclined state, the end of the bracket 33 away from the pivot 352 is engaged with the end of the bracket storage groove 223 away from the connecting edge 351; when the photovoltaic panel 2 is in a flat state, the bracket 33 is stored in the bracket storage groove 223.

[0065] Understandably, when the photovoltaic panel 2 is in a flat state, the bracket 33 is stored in the bracket storage groove 223, which effectively limits the shaking of the bracket 33 and prevents the bracket 33 from damaging the photovoltaic panel 2 and its components.

[0066] Understandably, when the photovoltaic panel 2 is tilted, the bracket 33 is engaged in the groove of the bracket storage groove 223. The groove wall of the bracket storage groove 223 effectively restricts the shaking of the bracket 33, further strengthens the connection between the bracket 33 and the photovoltaic panel 2, and improves the structural fixation strength of the photovoltaic panel 2 in the tilted state.

[0067] Furthermore, the mounting frame 22 also includes fasteners 222, with at least one fastener 222 provided on each side of each photovoltaic module 21, and the fasteners 222 are snapped into the side of the photovoltaic module 21.

[0068] Specifically, in this embodiment, each photovoltaic module 21 is provided with two fasteners 222 on both sides.

[0069] Understandably, the locking and engaging mechanism between the fastener 222 and the photovoltaic module 21 strengthens the fixing strength of the photovoltaic module 21 on the mounting frame 22, greatly improving the structural stability of the photovoltaic panel 2.

[0070] Furthermore, an inverter 23 is installed on the side of the photovoltaic panel 2 closest to the base plate 3.

[0071] Understandably, the photovoltaic module 21 receives light energy and converts it into electrical energy, outputting it in the form of direct current; the inverter 23 can convert the direct current into alternating current for direct use in residential homes, reducing the secondary power conversion process required before entering the home and improving the practicality of the photovoltaic module 1.

[0072] Please see Figures 1-5 Furthermore, the base plate 3 has at least one drainage groove 34 along the frame 35; the frame 35 also includes frame corners 355 at the four corners of the frame 35, and drainage holes 3551 are opened on the surface of each drainage groove 34 at both ends of the frame corners 355.

[0073] Specifically, in this embodiment, the base plate 3 has four drainage grooves 34 along the frame 35, and two drainage holes 3551 are correspondingly opened on each frame corner 355.

[0074] Understandably, the design of the drainage channel 34 facilitates the timely collection of rainwater during rainy weather by the photovoltaic module 1, and discharges it to the outside of the photovoltaic module 1 through the drainage hole 3551. This prevents rainwater from accumulating on the photovoltaic panel 2, causing residual mud and sand after evaporation to form a dust accumulation belt, which would obstruct the surface of the photovoltaic panel 2 and affect the light energy conversion efficiency of the photovoltaic module 21. This greatly improves the functional stability and working efficiency of the photovoltaic module 1.

[0075] Understandably, the hinge 353 also acts as a photovoltaic flow guide, using surface tension to guide rainwater on the photovoltaic panel 2 to flow around the hinge 353, and finally through the hinge 353 into the drainage channel 34, further enhancing the drainage efficiency of the drainage channel 34 and the drainage hole 3551.

[0076] Furthermore, at least one connecting hole 3552 is provided on the side of the frame corner 355 that is connected to the adjacent side of the connecting edge 351.

[0077] Specifically, in this embodiment, each frame corner 355 has two connection holes 3552.

[0078] Understandably, by setting the connection hole 3552, when multiple photovoltaic modules 1 need to be spliced ​​together, the positions of the corresponding connection holes 3552 on the adjacent frame 35 between two adjacent photovoltaic modules 1 are opposite, which facilitates the use of screws or other connection methods to fix the connection, thereby achieving the effect of splicing integration and greatly improving the assemblability and practicality of photovoltaic module 1.

[0079] Furthermore, the frame corner 355 is higher than the frame 35 portion excluding the frame corner 355, and the height of the frame corner 355 is 200mm.

[0080] Understandably, multiple photovoltaic modules 1 can also be stored in a stacked manner when stored or transported. The height of the frame corner 355 provides a gap between the two photovoltaic modules 1 stacked on top of each other, so as to avoid the upper base plate 3 from bumping into the lower photovoltaic panel 2 and thus damaging the photovoltaic panel 2.

[0081] Furthermore, the frame 35 has handles 354 on the two adjacent sides of the connecting edge 351.

[0082] Understandably, the design of handle 354 makes it easier for users to lift the photovoltaic module 1 during installation, movement, or use, thus improving the ease of use of the photovoltaic module 1.
