The above steps substantially complete the manufacture of the flexible solar panel module 1000 of the present invention. The wirings 151 and 152 may be the back positive wiring 122b (122b') itself (the extension thereof) and the back negative wiring 112a (112a') itself (the extension thereof), or may be different wires. The junction box 150 further includes a positive electrode wiring 151' and a negative electrode wiring 152 to electrically connect the flexible solar panel module 1000 to the outside. A first waterproof rubber material such as a thermoplastic polyolefin (TPO) 160 is physically contacted with the flexible backing plate 140 between the adjacent inflexible cover plates, such as the glass cover plate 130, and is in an inflexible cover plate. A second waterproof rubber material such as butyl rubber 161 is disposed between the glass cover plate 130 and the flexible back plate 140 to protect the solar panel 100' (100) and its wiring from moisture and mechanical force. At the same time, the flexibility between the invisible cover plate and the glass cover plate 130 is taken into consideration, wherein the first waterproof rubber material 160 and the second waterproof rubber material 161 may be the same waterproof rubber material or different waterproof rubber materials. Another waterproof material such as a material similar to the flexible back sheet or a waterproof adhesive material such as thermoplastic polyolefin 170 may be selectively disposed on the exposed portions 151 and 152 of the flexible back sheet 140 to protect the wiring. 151 and 152 are not affected by moisture and mechanical force, while taking into account the flexibility of the flexible backing plate 140.

In the above embodiments of FIGS. 1-3 and 4, since the flexible back plate 140 has flexibility, as long as there is sufficient gap between the adjacent inflexible solar panels 100' (100), it is possible to achieve a plurality of Flexible in the foldable area (the area indicated by the distance d in Figures 1-3) Solar panel module 1000. In a preferred embodiment, the gap distance between the inflexible solar panels 100' (100) is not less than the inflexible solar panel 100 (100') and the inflexible cover such as the glass cover 130 (130' The sum of the thicknesses. In addition, when the back glass 102 of the inflexible solar panel 100 (100') and the inflexible cover such as the glass cover 130 are sufficiently thin, such as less than or equal to 2.0 mm, the inflexible solar panel 100 ( 100') will become bendable, further optimizing the flexibility of the flexible solar panel module 1000. Moreover, in the above embodiments of FIGS. 1-3 and 4, each of the inflexible solar panels 100' (100) in the flexible solar panel module 1000 is electrically connected to each other in parallel, but it should be understood that the present invention It can also be applied to solar panels that are electrically connected in series.

Referring now to Figure 4A, there is shown a partial enlarged view of a flexible solar panel module 1000 in accordance with the present invention, emphasizing the flexural state of the flexible back panel 140 and the distribution of the glue in the module 1000, so that the front and back are omitted. All wiring. As shown in FIG. 4A, when there is sufficient gap between adjacent inflexible covers such as the cover glass 130, the flexible back plate 140 is adjacent to the inflexible cover such as the cover glass 130. The flexible substrate 140 is closer to the inflexible cover such as the cover glass 130 at the edge of the inflexible cover such as the cover glass 130 due to the vacuum adsorption, but is limited by the inflexible The thickness of the cover plate such as the cover glass 130, the photoelectric element layer 101 and the back glass 102, the flexible substrate 140 is farthest from the invisible cover such as the glass cover at the center of the inflexible cover such as the cover glass 130. 130. Therefore, in practical applications, in addition to the two adjacent inflexible cover plates shown in FIG. 4, such as the first waterproof rubber material 160 between the glass cover plates 130, the invisible cover plate such as the glass cover plate 130 and the A second waterproof rubber 161 is disposed between the flexible back plates 140 to cover one side of the inflexible solar panel (as shown in FIG. 4A). The second waterproof rubber 161 includes the same material as the first waterproof rubber 160, such as A thermoplastic polyolefin (TPO), or a material different from the first waterproof rubber 160, such as a butyl rubber. Moreover, the reference numeral 162 of FIG. 4A represents the first package between the flexible back plate 140 and the back surface of the solar panel 100 or 100' (including the back glass 102 and the photovoltaic element layer 101), and the component number 103 of FIG. 4A represents An inflexible cover such as a second encapsulant between the cover glass 130 and the front side of the solar panel 100 or 100'. Since the solar panel 100 or 100' is covered by the encapsulating material (the first and second encapsulating materials) and/or the waterproof rubber (160 and 161) in all directions, the photovoltaic element layer 101 in the solar panel 100 or 100' can be avoided. Due to the influence of moisture, the quality is degraded, and the solar panels can be fixed to omit the frame required for the conventional solar panel module.

Referring now to Figures 5 and 6, there are shown a top view and a fixed cross-sectional view, respectively, of a flexible solar panel module 1000 in accordance with the present invention.

The flexible solar panel module 1000 of the present invention can be mass-produced by paralleling the plurality of solar panels 100 and 100' and can be adapted to various terrains by virtue of its flexibility, and thus can be permanently fixed to the installation. In view of the above situation considerations, fixed fixation and waterproofness should be strengthened. To achieve this, the first waterproof rubber 160 (or the third waterproof rubber material having the same or different materials) may be disposed between the inner edge of the fixing hole and the fixing member 210 to minimize the gap between the fixing member 210 and the fixing hole. Clearance, and additionally set the first waterproof rubber 160 (or the third waterproof rubber with the same material or different materials) to be flexible The back surface of the back plate 140 surrounds the fixing hole to prevent moisture from penetrating from the fixing hole. In order to further increase the water repellency, the selective waterproof cushions 181 and 182 may be respectively disposed above the fixing hole and below the fixing hole to cover the upper side of the fixing hole.

To increase the strength and extent of attachment, a selective lowering member 200 can be added to the flexible backing plate 140. The left and right extension width of the lower pressing member 200 can be adjusted to cover the glass cover 130 (as shown in Fig. 6) or to be limited to only between the solar panels 100 and 100'. The extension length of the pressing member 200 can also be adjusted to exceed the width of the flexible solar panel module 1000 (as shown in FIG. 5) or to be much shorter than the width of the flexible solar panel module 1000. It is distributed in the solar panel module 1000 in an island manner. The shape and size of the waterproof cushion 181 may be the same as or different from that of the lower pressing member 200, for example, may extend onto the glass cover plate 130, extend the side wall of the solar panel 100/100' or be adjacent to the adjacent solar panel 100. Between 100'. The fixing member 210 may be, for example, a screw, a rivet, a fastener, or the like. Depending on the extension of the lower pressing member 200, the lower pressing member 200 may have a plurality of holes to match the plurality of fixing members 210 (as shown in FIG. 5), or the lower pressing member 200 has only one hole to match the single fixing member. 210. If the permanent solar panel module 1000 is to be permanently fixed, the thermoplastic material may be selectively laid on the fixing surface (such as the front surface of the roof panel 500 or the ground, for example) before being fixed, and then the new type is laid. The flexible solar panel module 1000 directly fixes the flexible solar panel module 1000 on the fixing surface.

The flexible solar panel module of the present invention can generate a large amount of power, and the flexible design can adapt to various terrains, and the high waterproof performance has the advantage of high reliability. In addition, the flexible solar panel module of the present invention is easy to manufacture and easy to fix, and can greatly reduce the cost and has great industrial value.

The junction box 150 further includes a positive electrode wiring 151' and a negative electrode wiring 152' to electrically connect the flexible solar panel module 1000 to the outside. A first waterproof rubber material such as a thermoplastic polyolefin (TPO) 160 is physically disposed between the adjacent glass cover plates 130 and the flexible back plate 140 is in contact with the glass cover plate 130 and the flexible back plate 140. A second waterproof rubber material such as butyl rubber 161 is disposed to protect the solar panel 100' (100) and its wiring from moisture and mechanical force, and at the same time, the flexibility between the glass cover plates 130 is considered. The first waterproof rubber material 160 and the second waterproof rubber material 161 may be the same waterproof rubber material or different waterproof rubber materials. Another waterproof material such as a material similar to the flexible back sheet or a waterproof adhesive material such as thermoplastic polyolefin 170 may be selectively disposed on the exposed portions 151 and 152 of the flexible back sheet 140 to protect the wiring. 151 and 152 are not affected by moisture and mechanical force, while taking into account the flexibility of the flexible backing plate 140.

In the above embodiments of FIGS. 1-3 and 4, since the flexible back plate 140 has flexibility, as long as there is sufficient gap between the adjacent inflexible solar panels 100' (100), it is possible to achieve a plurality of A flexible solar panel module 1000 in a foldable region (the region indicated by the distance d in Figures 1-3). In a preferred embodiment, the gap distance between the inflexible solar panels 100' (100) is not less than the sum of the thicknesses of the inflexible solar panel 100 (100') and the glass cover panel 130 (130'). In addition, when the back glass 102 and the glass cover 130 of the inflexible solar panel 100 (100') are sufficiently thin, such as less than or equal to 2.0 mm, the inflexible solar panel 100 (100') will become The flexibility of the flexible solar panel module 1000 can be further optimized by being bendable. Moreover, in the above embodiments of FIGS. 1-3 and 4, each of the inflexible solar panels 100' (100) in the flexible solar panel module 1000 is electrically connected to each other in parallel, but should It is understood that the present invention can also be applied to solar panels that are electrically connected in series.

Referring now to Figure 4A, there is shown a partial enlarged view of a flexible solar panel module 1000 in accordance with the present invention, emphasizing the flexural state of the flexible back panel 140 and the distribution of the glue in the module 1000, so that the front and back are omitted. All wiring. As shown in FIG. 4A, when there is sufficient gap between adjacent glass cover plates 130, the flexible back plate 140 is in a flexible state between adjacent glass cover plates 130, due to vacuum adsorption. The flexible substrate 140 is closer to the glass cover 130 at the edge of the cover glass 130, but is limited by the thickness of the cover glass 130, the photovoltaic element layer 101 and the back glass 102, and the flexible substrate 140 is in the cover glass 130. The center will be farthest from the glass cover 130. Therefore, in practical applications, in addition to the first waterproof rubber 160 between the two adjacent glass cover plates 130 shown in FIG. 4, a second waterproof rubber is also disposed between the glass cover 130 and the flexible back plate 140. The material 161 covers one side of the inflexible solar panel (as shown in FIG. 4A). The second waterproof rubber 161 comprises the same material as the first waterproof rubber 160 such as a thermal plastic polyolefin (TPO), or a material different from the first waterproof rubber 160 such as a butyl rubber. Moreover, the reference numeral 162 of FIG. 4A represents the first package between the flexible back plate 140 and the back surface of the solar panel 100 or 100' (including the back glass 102 and the photovoltaic element layer 101), and the component number 103 of FIG. 4A represents A second encapsulant between the cover glass 130 and the front side of the solar panel 100 or 100'. Since the solar panel 100 or 100' is covered by the encapsulating material (the first and second encapsulating materials) and/or the waterproof rubber (160 and 161) in all directions, the photovoltaic element layer 101 in the solar panel 100 or 100' can be avoided. Due to the influence of moisture, the quality is degraded, and the solar panels can be fixed to omit the frame required for the conventional solar panel module.

Referring now to Figures 5 and 6, there are shown a top view and a fixed cross-sectional view, respectively, of a flexible solar panel module 1000 in accordance with the present invention. Fix this new type When the flexible solar panel module 1000 is used, a flexible back can be provided between the solar panels 100 and 100' and/or between the solar panel 100/100' and the junction box 150 and/or around the solar panels 100 and 100' A plurality of fixing holes are arranged in the board 140 (and the first waterproof rubber material 160) (one of the fixing holes is shown in FIG. 6), and the flexible solar panel module 1000 is fixed to a fixing surface by using the fixing member 210 through the fixing hole. The upper surface of the shingle or other support frame 500. The flexible solar panel module 1000 of the present invention can be mass-produced by paralleling the plurality of solar panels 100 and 100' and can be adapted to various terrains by virtue of its flexibility, and thus can be permanently fixed to the installation. In view of the above situation considerations, fixed fixation and waterproofness should be strengthened. To achieve this, the first waterproof rubber 160 (or the third waterproof rubber material having the same or different materials) may be disposed between the inner edge of the fixing hole and the fixing member 210 to minimize the gap between the fixing member 210 and the fixing hole. The gap, and additionally, the first waterproof rubber 160 (or the third waterproof rubber material having the same or different materials) is disposed on the back surface of the flexible back plate 140 around the fixing hole to prevent water vapor from infiltrating from the fixing hole. In order to further increase the water repellency, the selective waterproof cushions 181 and 182 may be respectively disposed above the fixing hole and below the fixing hole to cover the upper side of the fixing hole.

To increase the strength and extent of attachment, a selective lowering member 200 can be added to the flexible backing plate 140. The left and right extension width of the lower pressing member 200 can be adjusted to cover the glass cover 130 (as shown in Fig. 6) or to be limited to only between the solar panels 100 and 100'. The extension length of the pressing member 200 can also be adjusted to exceed the width of the flexible solar panel module 1000 (as shown in FIG. 5), or the length thereof is much smaller than the width of the flexible solar panel module 1000. It is distributed in the solar panel module 1000 in an island manner. The shape and size of the waterproof cushion 181 may be the same as or different from that of the lower pressing member 200, for example, may extend onto the glass cover plate 130, extend the side wall of the solar panel 100/100' or be adjacent to the adjacent solar panel 100. Between 100'. The fixing member 210 is for example It can be screws, rivets, fasteners, etc. Depending on the extension of the lower pressing member 200, the lower pressing member 200 may have a plurality of holes to match the plurality of fixing members 210 (as shown in FIG. 5), or the lower pressing member 200 has only one hole to match the single fixing member. 210. If the permanent solar panel module 1000 is to be permanently fixed, the thermoplastic material may be selectively laid on the fixing surface (such as the front surface of the roof panel 500 or the ground, for example) before being fixed, and then the new type is laid. The flexible solar panel module 1000 directly fixes the flexible solar panel module 1000 on the fixing surface.
