Description

The present invention relates to a roof-integrated photovoltaic power generation device, and more specifically, it is a photovoltaic power generation device integrally configured with the roof and has excellent waterproofness, fire resistance, breathability, design, workability, etc. It relates to an integrated photovoltaic power generation device.

As a place to install a photovoltaic power generation device (solar cell panel) in a general house, it is an unused place that is not easily affected by the shadow of the house, has excellent solar radiation conditions, and further affects daily life. The roof is selected because it does not exist.

The form of installing the solar cell panel on the roof can be roughly classified into "roof-standing type", "roof-integrated type", and "roof material-integrated type". In the roof-standing type photovoltaic power generation device, a fixing pedestal is attached to the roof after the roof of the house is completed, and a solar cell panel is attached to the fixing pedestal. Therefore, the solar cell panel and the gantry protrude from a general roofing material (roof tile, flat roof tile, slate roof tile, etc.) and have a floating appearance (see, for example, FIG. 11 of Patent Document 1). In addition, since a hole is made in the roof material to attach the gantry, there is a problem in waterproofness and the like. Furthermore, there was a problem in the repair and maintenance of roofing materials.

On the other hand, in the roof-integrated photovoltaic power generation device, a dedicated roofing material and a solar cell panel mounting frame are provided on the roofing laid on the roofing field board before the usual roofing material is laid. Further, after the solar cell panel is laid, a conventional roofing material is laid adjacent to the solar cell panel. Therefore, the roof-integrated photovoltaic power generation device has an appearance as if the solar cell panel constitutes a part of the roof.

However, the roof-integrated photovoltaic power generation device has a unique problem that is not found in the roof-mounted photovoltaic power generation device. First, since the distance (gap) between the solar cell panel and the roof is small, it is difficult to secure sufficient air permeability to dissipate the heat generated by the solar cell panel. Therefore, heat tends to be trapped in the gap between the solar cell panel and the roof. As a result, the temperature of the solar cell panel rises and the power generation efficiency of the cell (power generation element) decreases.

Further, since the gap between the solar cell panel and the roof is small, it is not easy to attach / detach various electric wires (power line, signal line) between the solar panel and the solar panel. Therefore, when a problem such as a wiring defect occurs, there is a problem that maintenance takes time, and as a result, maintenance cost increases.

For a photovoltaic power generation device with an integrated roofing material, the solar cell panel must be manufactured with fireproof specifications and must be certified as fireproof. The structure uses a multi-layered fireproof sheet in which the back sheet material of the solar cell module contains iron foil. Therefore, the cost is very high. In addition, a solar cell module having a super straight structure is usually formed into a box structure with a metal plate on the back surface to form a solar cell panel integrated with a roofing material. All of them are extremely costly, and solar power generation devices integrated with roofing materials have not become widespread (see, for example, Patent Document 3).

By the way, a corrugated plate structure in which concave portions and convex portions are alternately continuous at regular intervals is attached to the roof (field plate) on the field plate so that the longitudinal direction of the concave portions (convex portions) coincides with the flow direction of rainwater. An invention relating to a roof-integrated photovoltaic power generation device in which a solar cell panel is fixed to the corrugated sheet structure via a mounting bracket is known (see, for example, Patent Document 4).

In the above-mentioned photovoltaic power generation device, it is possible to secure sufficient air permeability between the solar cell panel and the field plate by the corrugated plate structure and the mounting bracket to release the heat generated by the solar cell panel. Further, since both ends of the corrugated sheet structure are open, rainwater that has entered between the solar cell panel and the field plate can be drained.

Japanese Unexamined Patent Publication No. 2006-089978 Japanese Unexamined Patent Publication No. 2011-163060 Japanese Unexamined Patent Publication No. 2004-238997 Patent No. 5750260

In the case of the roof-integrated photovoltaic power generation device described in Patent Document 4, the solar cell panel is separated from the roof by the corrugated sheet structure. Therefore, the height of the entire device from the roof becomes high. This spoils the appearance of the photovoltaic power generation device.

In addition, although it is a very rare case, the solar cell panel may ignite. Therefore, fireproofness is required for all the "roof-standing type", "roof-integrated type", and "roofing material-integrated type" photovoltaic power generation devices so that the flame does not ignite the roofing material.

Therefore, the present invention was made in view of the above-mentioned problems of the prior art, and the purpose of the present invention is to provide a roof-integrated photovoltaic power generation device having excellent waterproofness, fireproofness, breathability, design and workability.

In this roof-integrated photovoltaic power generation device 100 (hereinafter, referred to as "this photovoltaic power generation device 100"), the solar cell panel 10 has the same inclination angle as the roof 1, and the gap with the roof 1 is minimized. It is attached to 1. Therefore, when the solar power generation device 100 is viewed from a distance, the solar cell panel 10 has an appearance as if it constitutes a part of the roof 1 (roof material 1a). Although the details will be described later with reference to FIG. 4, a base metal 40 is installed on the surface (field plate) of the roof 1 facing the back surface of the solar cell panel 10 instead of the roof material 1a. Incidentally, the plane dimensions of the roof 1 in the present embodiment are, for example, about 5 m in the vertical dimension and about 8 m in the horizontal dimension, whereas the plane dimensions of the photovoltaic power generation device 100 are, for example, about 4 m in the vertical dimension and about 8 m in the horizontal dimension.

Therefore, the back sheet is a multi-layered film having various performances (polyvinyl fluoride (PVF), polyethylene terephthalate (PET), etc.).

The sealing material 10d is made of, for example, butyl rubber, silicone rubber, or a mixture thereof.

As shown in FIG. 2, the intermediate panel fixing portion 20 is a fixing mechanism for fixing the opposite ends of two adjacent solar cell panels 10 and 10, respectively. The photovoltaic power generation device 100 uses eight intermediate panel fixing portions 20. The intermediate panel fixing portion 20 includes an intermediate vertical rack mechanism 21 that is vertically arranged and supports the lower surfaces of the ends of the two adjacent solar cell panels 10 and 10, and two that are also vertically arranged and adjacent to each other. It is composed of an intermediate vertical clamp mechanism 22 that presses the upper surface of the end portions of the solar cell panels 10 and 10.

The intermediate vertical rack mechanism 21 includes a hem portion 21a, a raised portion 21b, a rail portion 21c, and a hollow square tunnel portion 21d. The hem portion 21a is fixed to the field board 1c by the screw 21e. The raised portion 21b defines a gap between the solar cell panel 10 and the base metal 40. The rail portion 21c supports the lower surface of the end portion of the solar cell panel 10. A rivet nut 24 screwed to the bolt 23 is attached to the hollow square tunnel portion 21d.

In the intermediate vertical clamp mechanism 22, the bolt 23 is screwed to the rivet nut 24, so that the joint portion 22a presses the solar cell panel 10 against the rail portion 21c of the intermediate vertical rack mechanism 21 to fix the solar cell panel 10.

As shown in FIG. 3, the right end panel fixing portion 30R is a fixing mechanism for fixing the right end portion of the solar cell panel 10 located at the right end in the drawing. The photovoltaic power generation device 100 uses two right end panel fixing portions 30R. The right end panel fixing portion 30R is arranged in the vertical direction and is also arranged in the vertical direction with the right end vertical rack mechanism 31 that supports the lower surface of the end portion of the solar cell panel 10 located at the right end in the drawing. It is composed of a right end vertical clamp mechanism 32 that presses the upper surface of the end portion of the solar cell panel 10 located at.

The right end vertical rack mechanism 31 is composed of a hem portion 31a, a raised portion 31b, a rail portion 31c, and a hollow square tunnel portion 31d. The hem portion 31a is fixed to the field board 1c by the screw 31e. The raised portion 31b defines a gap between the solar cell panel 10 and the base metal 40. The rail portion 31c supports the lower surface of the end portion of the solar cell panel 10. A rivet nut 34 screwed to the bolt 33 is attached to the hollow square tunnel portion 31d. Further, a linear convex portion 31f is formed on the upper surface of the hollow square tunnel portion 31d. The linear convex portion 31f fits into the concave groove 32b of the right end vertical clamp mechanism 32. By fitting the linear convex portion 31f into the concave groove 32b of the right end vertical clamp mechanism 32, the right end vertical clamp mechanism 32 is positioned on the right end vertical rack mechanism 31.

In the right end vertical clamp mechanism 32, the bolt 33 is screwed to the rivet nut 34, so that the joint portion 32a presses the solar cell panel 10 against the rail portion 31c of the right end vertical rack mechanism 31 to fix the solar cell panel 10.

The left end panel fixing portion 30L (FIG. 1) for fixing the left end portion of the solar cell panel 10 located at the left end has a symmetrical relationship with the right end panel fixing portion 30R. Therefore, the above items also apply to the left end panel fixing portion 30L. Therefore, the description of the left end panel fixing portion 30L will be omitted here.

The base metal 40 is laminated on the waterproof sheet 1b (FIG. 2) of the roof 1. The base metal 40 is fixed to the waterproof sheet 1b by passing a nail through the base metal 40 through the field plate 1c.

Since the base metal 40 has waterproofness, the waterproof performance of the roof 1 is remarkably improved in combination with the waterproof effect of the tarpaulin 1b. Further, for example, there may be a case where leaves are deposited on a part of the surface of the solar cell panel 10, the solar cell panel 10 is overheated, and the solar cell panel 10 is thermally melted. In this case, ethylene vinyl acetate (EVA) or the like inside may dissolve to the outside. However, even when the high-temperature EVA or the like melts to the outside, the base metal 40 acts as a barrier to prevent the EVA or the like from coming into contact with the waterproof sheet 1b and the field plate 1c. This makes it possible to prevent jumping (ignition) from the solar cell panel 10 to the roof 1 (waterproof sheet 1b and field plate 1c).

The ridge cover 50 is a cover for preventing rainwater, dust, and small animals from entering the gap between the solar cell panel 10 and the roof 1 from the ridge side. The ridge cover 50 is attached to the roof 1 via the ridge cover base 52 (FIG. 6). Further, the ridge cover base 52 is provided with a vent for forming an air flow (ventilation) in the gap between the solar cell panel 10 and the roof 1. The ridge cover 50 will be described later with reference to FIGS. 5 to 8.

The eaves cover 60 is a cover for preventing rainwater and dust from entering the gap between the solar cell panel 10 and the roof 1 from the eaves side. The eaves cover 60 is provided with a vent (FIG. 10) for forming an air flow (breathability) in the gap between the solar cell panel 10 and the roof 1. Therefore, the air that has entered the gap between the solar cell panel 10 and the roof 1 through the vent of the eaves cover 60 is exhausted to the atmosphere from the vent of the ridge cover base 52 (FIG. 6) while cooling the back surface of the solar cell panel 10. Will be done. On the contrary, the air that has entered the gap between the solar cell panel 10 and the roof 1 through the vent of the ridge cover base 52 (FIG. 6) cools the back surface of the solar cell panel 10 and air from the vent of the eaves cover 60. Is exhausted to. The eaves cover 60 will be described later with reference to FIGS. 9 and 10.

FIG. 4 is an explanatory view showing an installation area on the roof 1 of the base metal 40, 40'according to the present invention. The outermost rectangular portion represents the installation area A3 of the tarpaulin 1b of the roof 1, and the innermost rectangular shaded portion represents the installation area A2 on the roof 1 of the solar cell panel 10. The rectangular portion located between these represents the installation area (hereinafter, referred to as “envelope base metal 400”) on the roof 1 of the base metal 40,40'.

As the base metal used in the present embodiment, the base metal 40'for the eaves and the base metal 40 other than the eaves 40 are used. The number of base metals 40 used in this embodiment is six. To give a dimensional example, it is 910 mm in length × 6500 mm in width × 0.35 mm in plate thickness. The number and dimensions are examples, and the number and dimensions are not limited to this.

On the other hand, the number of base metals 40'is two. To give an example of dimensions, it is 350 mm in length × 3350 mm in width × 0.35 mm in plate thickness. The number and dimensions are examples, and the number and dimensions are not limited to this.

In the base metal 40,40', the base metal 40,40'located on the lower side from the ridge side along the eaves side is mixed with the base metal 40, 40'located on the upper side by a predetermined overlapping width d1. They are arranged in order without gaps in a form (overlapping). The dotted line on the figure represents the tip of the base metal 40, 40'that is mixed with the base metal 40 located on the upper side by a predetermined overlapping width d1. Regarding the base metal 40', in addition to the above-mentioned stacking width d1, the base metal 40' located on the left side in the drawing by the stacking width d2 along the sleeve side is the base metal 40'located on the right side in the drawing. It is arranged in a crowded (overlapping) form on the lower side. To give a dimensional example, the stacking width d1 = 150 mm and the stacking width d2 = 100 mm. The dimensions are an example and are not limited to this.

On the base metals 40 and 40', a left end panel fixing portion 30L for supporting the solar cell panel 10, an intermediate panel fixing portion 20, and a right end panel fixing portion 30R are installed, respectively. The installation area of the base metal 40, 40'(envelope base metal 400) completely covers the installation area A2 of the solar cell panel 10. Therefore, as described above, when the solar cell panel 10 is thermally melted for some reason, the base metals 40, 40'become a barrier, and the ethylene vinyl acetate (EVA) or the like inside becomes the waterproof sheet 1b and the field. Prevents contact with the main plate 1c.

Further, since the base metal 40,40'is installed on the waterproof sheet 1b, the roof 1 is covered with the waterproof sheet 1b and the base metal 40,40'. In this way, the waterproofness of the roof 1 is further improved by the base metals 40, 40'.

Further, the roofing material 1a is not installed on the installation area A2 of the solar cell panel 10. The roofing material 1a is installed in an area excluding the installation area A2 of the solar cell panel 10 from the surface of the roof 1 (FIG. 1).

5 to 8 are explanatory views showing a ridge cover 50 according to the present invention. FIG. 5 is an enlarged view of part C of FIG. FIG. 6 is a cross-sectional view taken along the line DD of FIG. FIG. 7 is a cross-sectional view taken along the line FF of FIG. FIG. 8 is a view taken along the line G of FIG.

As shown in FIG. 5, the ridge cover 50 seals the ridge cover main body 51, the ridge cover base 52 that supports the ridge cover main body 51, and the left and right openings of the ridge cover main body 51 and the ridge cover base 52. It is composed of a ridge corner cover 53 and a screw 54 for fixing the ridge corner cover 53 to the ridge cover main body 51.

As shown in FIG. 6, the ridge cover main body 51 has a bent plate structure in which the lower roof parallel plate 51a, the diagonal plate 51b, and the upper roof parallel plate 51c are continuously connected in this order.

The ridge cover base 52 is formed by bending the roof parallel plate 52a, the roof vertical plate 52b, the ridge cover parallel plate 52c, the ridge cover vertical plate 52d, the rack parallel plate 52e, the rack vertical plate 52f, and the upper ridge cover parallel plate 52g in that order. It has a plate structure.

The ridge cover base 52 is fixed to the intermediate vertical rack mechanism 21 (left end vertical rack mechanism 31, right end vertical rack mechanism) and the field plate 1c by screws 52h, respectively. The ridge cover main body 51 is fixed to the ridge cover base 52 and the base metal 40 by screws 51d, respectively. The openings between the ridge cover main body 51, the base metal 40, the intermediate vertical rack mechanism 21, the solar cell panel 10, and the intermediate vertical clamp mechanism 22 are sealed by the ridge corner cover 53 (FIG. 5). The ridge cover main body 51 is formed with three C holes 51e on each side into which screws 54 (FIG. 5) for fixing the ridge corner cover 53 are screwed.

As shown in FIG. 7, a plurality of ventilation slit openings 52i are formed in the rack vertical plate 52f joined to the solar cell panel 10 of the ridge cover base 52.

Further, as shown in FIG. 8, a plurality of circular ventilation holes 52j are formed in the ridge cover vertical plate 52d facing the solar cell panel 10 of the ridge cover base 52.

Returning to FIG. 6, the air that has become hot due to heat exchange between the solar cell panel 10 and the solar cell panel 10 while flowing through the gap between the solar cell panel 10 and the base metal 40 is reflected by the roof vertical plate 52b and is reflected in the building. It is rectified by the cover parallel plate 52c. The rectified air is exhausted to the atmosphere through the ventilation holes 52j formed in the ridge cover vertical plate 52d and further through the ventilation slit openings 52i formed in the rack vertical plate 52f. In this way, an air flow (ventilation) is formed in the gap between the solar cell panel 10 and the base metal 40. As a result, the heat generated in the energy conversion of the solar cell panel 10 can be exhausted to the atmosphere by the flow of air (ventilation). As a result, heat does not accumulate in the gap between the solar cell panel 10 and the base metal 40, and it is possible to improve the decrease in power generation efficiency of the solar cell panel 10 due to heat.

9 and 10 are explanatory views showing an eaves cover 60 according to the present invention. FIG. 9 is an enlarged view of part E in FIG. FIG. 10 is a sectional view taken along the line HH of FIG.
As shown in FIG. 9, the eaves cover 60 is supported by the ends of the right end vertical rack mechanism 31 (intermediate vertical rack mechanism 21, left end vertical rack mechanism), and is fixed to these by screws 61.

As shown in FIG. 10, the eaves cover 60 has a bent structure in which a front diagonal plate 60a, a rack parallel plate 60b, a rack diagonal plate 60c, a rack vertical plate 60d, and a rear diagonal plate 60e are continuously connected in this order. ing. In particular, the hollow square tunnel portion 21d (hollow square tunnel portion 31d) is formed by forming a gap 60f between the rack diagonal plate 60c and the intermediate vertical rack mechanism 21 (right end vertical rack mechanism 31, left end vertical rack mechanism). It is possible to drain the accumulated rainwater to the outside.

The rear diagonal plate 60e drains the rainwater collected between the intermediate vertical clamp mechanism 22 and the intermediate vertical rack mechanism 21 and the rainwater collected on the surface of the solar cell panel 10 to the outside.

Further, an opening 60 g is formed between the front diagonal plate 60a and the base metal 40. Therefore, the air that cools the solar cell panel 10 through the opening 60 g is the solar cell panel 10 and the base metal 40.
The air that has flowed into the gap between the solar cell panel 10 and the base metal 40 from the ventilation slit port 52i and the ventilation hole 52j of the ridge cover base 52 cools the solar cell panel 10 and creates an atmosphere through the opening 60g. Will be exhausted to.

11 and 12 are explanatory views showing the wiring of the solar cell panel 10 according to the present invention. FIG. 11 is a plan view of the solar power generation device 100. FIG. 12 is a cross-sectional view taken along the line AA of FIG. For convenience of explanation, the terminals and cables of the solar cell panel 10 are arranged and shown on the same front surface side, but are actually arranged on the back surface side of the solar cell panel 10.

As shown in FIG. 11, the number of the solar cell panels 10 used in the present embodiment is 10, and the photovoltaic power generation device 100 includes, for example, five solar cell panels 10 arranged in the horizontal direction. There are two power supply systems. Therefore, the photovoltaic power generation device 100 includes two power supply systems, a first system and a second system.

One solar cell panel 10 has, for example, 144 cells 10a, and has one positive terminal 10f and one negative terminal 10g. Therefore, the positive terminals 10f and the negative terminals 10g of the adjacent solar cell panels 10 and 10 are bypass-connected by the connecting cable 11. The terminals 10f and 10g and the connecting cable 11 are connected by a connector. The positive terminal 10f and the negative terminal 10g at the ends are connected to the first system (+), the second system (+), the first system (−), and the second system (−), respectively.

The connecting cable 11 bypass-connected to the terminals 10f and 10g is locked to the intermediate panel fixing portion 20 (intermediate vertical rack mechanism 21). Therefore, the entire wiring is simplified, and the attachment / detachment of the terminals 10f and 10g and the connecting cable 11 becomes easy. As a result, maintenance work such as replacement of the solar cell panel 10 is simplified, and the time required for the maintenance work is shortened. As a result, the cost of maintenance work is reduced.

Further, as shown in FIG. 12, the intermediate vertical rack mechanism 21 on the ridge side and the intermediate vertical rack mechanism 21 on the eave side are arranged with a gap d3 in the vertical direction. In this case, the solar cell panel 10 on the ridge side and the solar cell 10 on the eaves side are arranged with a vertical gap d4. The vertical gap d3 of the intermediate vertical rack mechanism 21 is a gap for bypass connecting the positive terminal 10a and the negative terminal 10b with the connecting cable 10c. On the other hand, the vertical gap d4 of the solar cell panel 10 is a gap for thermally expanding and releasing thermal stress when the temperature of the solar cell panel 10 rises.

Although one embodiment of the present invention has been described above with reference to the drawings, the embodiment of the present invention is not limited to the above. That is, it is possible to add various modifications and improvements within the technical scope of the present invention. For example, the ventilation slit port 52i of the ridge cover base 52 may be circular or oval as long as it has a shape that ensures ventilation and prevents small animals from entering the gap between the solar cell panel 10 and the base metal 40. You may. Similarly, the ventilation hole 52j may be oval or rectangular as long as it has a shape that ensures ventilation.
