Description

  The present invention relates to a drainage structure for a solar cell module provided with a drainage channel for draining rainwater from above the solar cell module.

Conventionally, a solar cell panel has a frame-like frame attached around it and is handled as a solar cell module together with this frame. The frame includes an upper wall parallel to the upper surface (light-receiving surface) of the solar cell panel and a vertical wall extending downward from the upper wall. The upper wall is formed in a plate shape having a predetermined thickness and is in close contact with the upper surface of the solar cell panel.
This type of solar cell module is often mounted on an installation stand in a state where the longitudinal direction of the solar cell panel is oriented in the horizontal direction and the upper surface of the solar cell panel is oriented obliquely upward.

  Since such a solar cell module is installed outdoors, dirt, sand dust, or the like may accumulate. These dirt and sand are washed away from the upper surface of the solar cell panel by rainwater. However, since there is a level difference in the boundary between the upper wall of the frame and the solar cell panel by the thickness of the upper wall, part of the dust and sand remains with the rain water without getting over the level difference. When this residue accumulates and spreads over a wide area and covers the upper surface of the solar cell panel, sunlight is blocked and the amount of power generation is reduced.

As a conventional solar cell module which can eliminate such a malfunction, there are some which are indicated in patent documents 1-patent documents 5, for example.
In the solar cell modules disclosed in Patent Literature 1 and Patent Literature 2, drainage structures are employed at the corners of the frame corresponding to the four corners of the solar cell panel.
The frame disclosed in Patent Document 1 is configured by a frame member provided for each side of a solar cell panel having a rectangular shape, and a connecting member that connects the frame members at portions corresponding to the four corners of the solar cell panel. Has been.

The connecting member has a drainage structure including drainage grooves extending from the upper surface side of the solar cell panel to the outside of the frame.
In the frame disclosed in Patent Document 2, protrusions are provided on connecting members that connect the frame members at the four corners of the solar cell panel. The projecting pieces are sandwiched between the frame members, and a drainage groove is formed between the frame members.
The frames disclosed in Patent Documents 3 to 5 have a drainage channel formed by cutting out a part of the frame member.

The through hole 47 is formed so that the notch 41 of the first frame member 31 is opened. The number of through holes 47 is not limited to one as shown in FIG. A plurality of small diameter holes (not shown) may be formed instead of the single through hole 47.

  In the solar cell module 1 configured as described above, dirt and dust fall on the solar cell panel 2 during use. These foreign substances are caused to flow along the upper surface of the solar cell panel 2 with rain water when it rains. A part of the rainwater flowing together with such foreign matter is discharged out of the solar cell module 1 so as to get over the first frame member 31 at the lowest position of the solar cell module 1.

  Rainwater that could not get over the first frame member 31, that is, rainwater that remained without getting over the step formed at the boundary between the solar cell panel 2 and the upper wall 34 of the first frame member 31, It flows in the left and right direction through the frame member 31 and flows into the notch 41 and is discharged out of the frame 3 through the notch 41 and the drainage passages 42 and 43 of the first and second clamps 4A and 4B. The For this reason, the dust and sand that have fallen on the solar cell panel 2 are washed away without being left by rainwater.

The notch 41 can be easily formed by partially removing a part of the upper wall 34 of the frame 3. This means that the manufacturing costs are not so high.
Further, the pressing plate 21 of the first clamp 4A and the first and second pressing plates 26 and 27 of the second frame 4B are located above the portions located on both sides of the notch 41 in the upper wall 34 of the frame 3. And push this part downward. For this reason, the clamp 4 becomes a reinforcing material substantially, and the intensity | strength of the notch part where the intensity | strength of the flame | frame 3 is relatively low is supplemented.
For this reason, drainage structure of the solar cell module in which rain water, dirt or sand does not remain at the boundary between the solar cell panel 2 and the frame 3 while reducing the cost and preventing the strength of the frame 3 from being lowered. Can be provided.

  In this embodiment, the first clamp 4A and the second clamp 4B for fixing the both ends of the first frame member 31 in the left-right direction are the end of the first frame member 31 and the second frame. The end of the member 32 is pressed. For this reason, according to this embodiment, it becomes possible to support the solar cell module 1 firmly.

In the solar cell panel 2 according to this embodiment, as shown in FIG. 9, when the sealing material 14 is in close contact with the upper wall 34 of the frame 3, it corresponds to the notch 41 in the sealing material 14. The site can be removed.
For this reason, according to this embodiment, even if it is the solar cell module 1 which has the sealing material 14, rainwater does not accumulate in the level | step-difference part equivalent to the thickness of the sealing material 14, Therefore It is possible to wash away dirt and sand accumulated in the section with rain water.

The notches 41 according to this embodiment are provided at three locations, two locations on both ends in the longitudinal direction of the solar cell panel 2 and a central portion in the longitudinal direction.
For this reason, rainwater on the solar cell panel 2 is dispersed and smoothly discharged at three locations, so that foreign matters such as dust and sand can be reliably discharged by rainwater.

Of the pair of side surfaces 41a, 41a of the notches 41 provided at both ends of the upper wall 34 extending in the left-right direction according to this embodiment, the outer side surfaces 41a located on both ends of the upper wall 34 are frame-shaped. The frame 3 is positioned at a predetermined position with respect to the inner wall surface of the vertical wall 35 extending in the front-rear direction. The predetermined position is a position on the same plane as the inner wall surface of the vertical wall 35 extending in the front-rear direction, and a predetermined length away from the inner wall surface of the vertical wall 35 toward the center side in the left-right direction. Either one of the adjacent positions.
For this reason, the notch 41 is located in the corner | angular part of the solar cell module 1, and this corner | angular part is reinforced by the 1st clamp 4A or the 2nd clamp 4B. Therefore, the solar cell module can be supported more firmly.

  1st and 2nd clamp 4A, 4B by this embodiment is formed in the shape where the cross-sectional shape of the direction orthogonal to the left-right direction does not change from a left end to a right end. In this case, the first and second clamps 4A and 4B including the drainage channel 43 can be formed by extrusion molding by forming the drainage channel 43 into the concave groove 44 extending in the left-right direction. For this reason, by adopting this configuration, it becomes possible to provide the drainage channel 43 without increasing the number of man-hours, so that the manufacturing is easy and the manufacturing cost can be kept low.

(Variation of notch)
The notch can be configured as shown in FIG. In FIG. 19, the same or equivalent members as those described with reference to FIGS. 1 to 18 are denoted by the same reference numerals, and detailed description thereof is omitted as appropriate.
The side surface 41a of the notch 41 shown in FIG. 19 is inclined when viewed from above. The direction in which the side surface 41a is inclined is a direction in which the left-right width of the notch 41 gradually increases toward the center side of the solar cell panel 2 (upper side in FIG. 19).
The left-right width D1 of the outer end portion of the notch 41 shown in FIG. 19 is the same as the left-right width A of the notch 41 shown in the first and second embodiments, and the left-right width D2 of the inner end portion is It is larger than the width D1 (A).

  According to this configuration, since the notch 41 is widely opened at the step portion between the upper wall 34 of the first frame member 31 and the solar cell panel 2, dirt and sand are more easily discharged by rainwater.
