Description

  The present invention relates to a snow stop structure for a photovoltaic power generation panel, and relates to a technique for preventing snow on the photovoltaic power generation panel from falling under the eaves.

  Conventionally, on the eave side of a sloped roof, a snow stopper is installed on the roof material in order to prevent the snow that has accumulated on the roof from falling below the eave (see Patent Document 1 below).

In recent years, a photovoltaic power generation panel (hereinafter referred to as a “roof-integrated solar panel”) is installed on the roof surface together with the roofing material, or a photovoltaic power generation panel (hereinafter referred to as “installation type solar panel”) is provided on the roofing material. "Light panel") is installed.
For this reason, snow guards are installed on the eaves side frame of the photovoltaic power generation panel to prevent the snow on the ridge side solar power generation panel placed on the ridge side from falling on the eaves side of the snow guard to fall under the eaves. (See Patent Documents 2 and 3 below).

JP 09-242283 A JP 2012-255254 A JP 2003-184245 A

However, according to the snow stopper structure disclosed in Patent Document 3, when the sunlight illuminating the roof is inclined from the eaves side to the ridge side, the snow stopper is incident on the ridge side solar power generation panel. There was a problem that light generation was blocked and power generation efficiency was reduced.
As disclosed in Patent Document 2, it is conceivable that the height of the snow stopper is set to a height that does not block the light incident on the ridge-side solar power generation panel, but the snow stopper is low. It does not function as a snow stop. Therefore, it is not desirable to change the height required for the snow stopper.

On the other hand, it is also conceivable to prevent snow on the ridge-side solar power generation panel from falling below the eaves by using a snow stopper installed on the roof material as disclosed in Patent Document 1.
However, when the solar power generation panel is a stationary solar panel, snow falls from a position higher than that of the snow stopper, and therefore, the solar power generation panel may jump over the snow stopper and fall under the eaves.
On the other hand, in order to prevent jumping over the snow stopper, it is conceivable that the installation type solar panel is separated from the snow stopper and installed on the ridge side. However, it is necessary to set this separation distance to 500 mm or more from experience. There is a problem that a space for installing the installation type solar panel becomes small.

  The present invention provides a snow stop structure for a photovoltaic power generation panel created to solve the above-described problem, and suppresses a decrease in power generation efficiency of the ridge side photovoltaic power generation panel. It aims at providing the snow stop structure of the photovoltaic power generation panel which can suppress the snowfall from the top.

The snow stop structure of the solar power generation panel according to the present invention is a snow stop structure of the solar power generation panel that prevents snow on the solar power generation panel installed on the sloped roof from falling below the eaves,
A simulated panel that is arranged adjacent to the eaves side of the photovoltaic panel and forms the same plane as the upper surface of the photovoltaic panel, and is disposed on the simulated panel on the ridge side of the simulated panel And a snow stopper for preventing snow from falling on the ridge-side solar power generation panel to be arranged.

According to the present invention described above, the panel surface of the photovoltaic power generation panel expands to the eave side by the simulated panel arranged on the eaves side of the photovoltaic power generation panel, and the snow stopper is separated from the photovoltaic power generation panel. Can be installed on the eaves side. Therefore, by reducing the time and range in which the ridge-side shaded area of the snow stop that overlaps the ridge-side solar power generation panel overlaps the ridge-side solar power generation panel, the power generation efficiency reduction of the ridge-side solar power generation panel is suppressed. be able to.
And since it is possible to suppress the decrease in power generation efficiency of the ridge-side solar power generation panel, it is not necessary to lower the snow stopper, and since it is possible to use a snow stopper with the normally required height, the snow prevention function is ensured. Can be demonstrated.
Further, according to the present invention described above, since the snow stopper is installed on the simulated panel that is flush with the upper surface of the ridge-side solar power generation panel, the snow accumulation on the ridge-side solar power generation panel is reduced. There is no risk of jumping over the snow stop.
Furthermore, according to this invention mentioned above, snowfall can be prevented from on the ridge side photovoltaic power generation panel. Therefore, if it is an installation type solar panel provided with the snow stopper structure according to the present invention, the snow stopper provided on the roofing material as disclosed in Patent Document 1 below, on the ridge-side solar power generation panel. There is no need to prevent falling snow. In other words, it is not necessary to set the installation type solar panel 500 mm or more away from the snow stopper installed on the roofing material. Therefore, the problem that the space for installing the installation type solar panel is reduced can be avoided.

  It is preferable that the length in the gradient direction of the simulated panel is set to a length in which the ridge-side shade region of the snow stopper generated on the ridge side of the snow stopper does not overlap the ridge-side solar power generation panel. .

  According to the configuration described above, since the ridge-side shade area of the snow stopper does not overlap the ridge-side solar power generation panel at all, it is possible to avoid a decrease in power generation efficiency of the ridge-side solar power generation panel.

  Further, the ridge-side photovoltaic power generation panel and the simulated panel are arranged in the left-right direction of the sloped roof, and the length of the simulated panel in the left-right direction is the same as the length of the ridge-side photovoltaic power generation panel in the left-right direction. It is preferable that

  According to the configuration described above, the left and right end sides of the ridge-side photovoltaic power generation panel adjacent in the gradient direction and the left and right end sides of the simulated panel are substantially linear in the gradient direction. And the vertical joint between the building side photovoltaic power generation panels and the vertical joint of the simulation panel are substantially linear in the gradient direction. Therefore, each vertical joint can be closed using a straight vertical joint cover, facilitating water stop work, and improving the aesthetics of the panel surface formed by the ridge-side solar power generation panel and the simulated panel. I can plan.

  ADVANTAGE OF THE INVENTION According to this invention, the snow stop structure of the photovoltaic power generation panel which can suppress the fall of the power generation efficiency of a ridge side photovoltaic power generation panel and can suppress the snowfall from on the ridge side photovoltaic power generation panel is provided. be able to.

The U-shaped portion 13 and flanges 14 extending outward in the gradient direction from both ends of the U-shaped portion 13 are provided.

When the horizontal rail 4 is installed on the roof base R <b> 1, it is placed on the spacer 11, which is an elastic material, and the lower wall portion 13 a of the U-shaped portion 13 abuts on the upper surface of the spacer 11. And this lower wall part 13a penetrates the lower wall part 13a itself and the spacer 11, and is clamp | tightened by the head of the screw | thread 20 fixed to the roof base | substrate R1 (surface material R2 and rafter R3), and the horizontal rail 4 is attached. It is fixed to the roof base R1.
The flange 14 is a part that supports the solar cell module 2 and the simulated panel 5 disposed above. And since the flange 14 is extended along the gradient direction, the solar cell module 2 and the simulation panel 5 are also supported in the state parallel to the gradient direction (refer FIG. 2).

Further, a ridge 15 is formed at the central portion of the horizontal rail 4 in the gradient direction. And the solar cell module 2 and the simulation panel 5 which the flange 14 supports are contact | abutted to the side wall part of this protrusion 15, and the solar cell module 2 and the simulation panel 5 are arranged in the left-right direction (refer FIG. 1).

(Solar cell module 2)
As shown in FIG. 1, the solar cell module 2 is a panel-like device that performs photoelectric conversion.
The plurality of solar cell modules 2 are arranged in the left-right direction along the ridges 15 (see FIG. 3) of the horizontal rail 4, and the adjacent solar cell modules 2 are electrically connected to each other to form a solar cell. The array 3 is configured.
Moreover, in this embodiment, the several solar cell module 2 is arrange | positioned 2 each at a gradient direction. Therefore, the solar cell array 3 is composed of two solar cell arrays 3a in the first row provided on the eaves side and a second row solar cell array 3b provided in the building side. The solar cell array 3a in the first row is located near the eaves of the roof R and is disposed above the eaves beam R4. Moreover, the solar cell module which comprises the solar cell array 3b of the 2nd row is a structure corresponded to the "ridge side solar cell panel" described in a claim.

(Simulation panel 5)
As shown in FIGS. 1 and 2, the simulated panel 5 is a member that is installed on the horizontal rail 4 to form the same plane as the solar cell module and enlarges the panel surface formed by the solar cell module 2.
The simulated panel 5 according to the present embodiment is formed in a rectangular column that is long in the left-right direction.
As shown in FIG. 1, the plurality of simulated panels 5 are arranged in the left-right direction between the first-row solar cell array 3 a and the second-row solar cell array 3 b to form the solar cell module 2. The panel surface is enlarged in the gradient direction. In addition, a plurality of simulated panels 5 are arranged side by side in the gradient direction between the first row solar cell array 3a and the second row solar cell array 3b. Hereinafter, the simulated panel 5 disposed on the eaves side is referred to as an eaves side simulated panel 5a, and the simulated panel 5 disposed on the ridge side is referred to as a ridge side simulated panel 5b. In addition, the ridge side simulation panel 5b is a structure corresponded to the "simulation panel" described in a claim.

As shown in FIG. 1, the length of the simulated panel 5 in the left-right direction is substantially the same as the length of the solar cell module 2 in the left-right direction. Therefore, the vertical joints between the plurality of simulated panels 5 arranged on the horizontal rail 4 and arranged in the left-right direction, the vertical joints of the solar cell array 3a in the first row, and the vertical joints of the solar cell array 3b in the second row However, it is substantially linear in the gradient direction.
Therefore, the linear vertical joint cover 21 that can continuously block the vertical joints of the plurality of simulated panels 5, the vertical joints of the first row of solar cell arrays 3a, and the second row of solar cell arrays 3b is used. Thus, the water-stopping work of the vertical joint becomes easy, and the aesthetic appearance of the panel surface formed by the solar cell module 2 and the simulated panel 5 can be improved.

In addition, as shown in FIG. 2, the thickness of the simulated panel 5 is substantially the same as the thickness of the solar cell module 2. Therefore, the upper surface of the simulation panel 5 supported by the flange 14 of the horizontal rail 4 and the upper surface of the solar cell module 2 form substantially the same plane. Therefore, it is suppressed that the fallen leaves etc. which flow to the eaves side by rainwater are latched by the panel surface which the solar cell module 2 and the simulation panel 5 form.
Note that the length of the simulation panel 5 in the gradient direction will be described later.

As shown in FIG. 3, the horizontal joint between the eaves-side simulated panel 5a and the ridge-side simulated panel 5b disposed on the flange 14 of the horizontal rail 4 is covered with a horizontal joint plate 16 with a sealing material to stop. It is watered.
Further, on the horizontal joint plate 16, there is disposed a fixing plate 18 having a substantially U-shaped cross-sectional view in which the end portion on the ridge side and the end portion on the eaves side extend downward and contact the upper surface of the simulation panel 5.
Then, the head of the nut N that passes through the horizontal joint plate 16 and the fixed plate 18 and is screwed to the shaft portion of the bolt B fastens the fixed plate 18, and the simulated panel 5 is fixed to the horizontal rail 4.

(Snow stop rail 6)
As shown in FIG. 3, the snow stop rail 6 is a member formed by bending a plate made of aluminum or stainless steel that is long in the left-right direction or a steel plate that has been subjected to rust prevention treatment. The snow stop rail 6 is disposed above the horizontal joint plate 16 between the eaves-side simulated panel 5a and the ridge-side simulated panel 5b and has a lower wall portion 7 extending in a gradient direction and a lower wall portion 7 in a side sectional view. A side wall portion 8 extending upward from the ridge side end portion of the ridge side so as to be perpendicular to the gradient direction, and an upper wall portion 9 extending from the upper end of the side wall portion 8 to the eaves side to improve strength. Yes.

  A through hole 7a perpendicular to the gradient direction is formed at the central portion of the lower wall portion 7 in the gradient direction so that the shaft portion of the cylindrical nut N can penetrate the lower wall portion 7. And the head of the nut N which penetrates the through-hole 7a fastens the lower wall part 7, the snow stop rail 6 is fixed to the horizontal rail 4, and on the panel surface which the solar cell module 2 and the simulation panel 5 form. A snow stop rail 6 is installed. In addition, as shown in FIG. 1, the position where the snow stop rail 6 is installed is on the simulation panel 5 which forms the same plane as the solar cell module 2, and includes the eaves side simulation panel 5a and the ridge side simulation panel 5b. Between. Therefore, the snow stop rail 6 is separated from the solar cell array 3a in the first row by the length in the gradient direction of the eaves-side simulation panel 5a, and is simulated in the ridge side with respect to the solar cell array 3b in the second row. The panel 5b is separated by the length in the gradient direction.

The side wall part 8 is orthogonal to the upper surface of the ridge side simulation panel 5b. Therefore, the snow on the building side simulated panel 5b and the solar cell array 3b in the second row sliding down to the eave side along the gradient is locked by the side wall portion 8 so as not to fall below the eaves.
Further, the height of the side wall 8 (the length orthogonal to the mating direction) is formed to a length that can reliably lock the snow cover of the ridge-side simulated panel 5b and the second row solar cell array 3b, for example, 40 mm to 50 mm. Has been. In addition, the length which can latch snow cover reliably changes with the gradient of the roof R, and the snow cover amount, and this invention is not limited to the above-mentioned length.
Further, the side wall 8 is formed with a hole 8a penetrating in the gradient direction. Therefore, rainwater or fallen leaves that move toward the eaves along the roof surface can easily move below the eaves without being locked to the side wall portion 8.
In addition, the ridge-side simulated panel 5b disposed on the ridge side with respect to the snow stop rail 6 preferably has a higher friction coefficient in order to make it difficult for the snow on the upper surface to slide.

Next, the length of the simulation panel 5 in the gradient direction will be described with reference to FIG.
The length of the simulated panel 5 in the gradient direction corresponds to a shaded area that occurs when the snow stop rail 6 prevents the sunlight from entering. Here, the irradiation angle of sunlight changes in date and time, and the shaded area also changes. Therefore, below, the length of the gradient direction of the eaves side simulation panel 5a and the ridge side simulation panel 5b is demonstrated together with description of the shade area | region which generate | occur | produces in the solar power generation system 1. FIG.

When the sunlight irradiating the roof R is inclined from the eave side to the ridge side (see arrow E in FIG. 2), the snow stop rail 6 is projected on the roof surface on the ridge side with respect to the snow stop rail 6. (See the broken line E1 in FIG. 2), the ridge side shade region S2 is generated.
The length of the ridge-side simulated panel 5b in the gradient direction is set so that the ridge-side shaded region S2 does not always overlap the solar cell array 3b in the second row. That is, when the ridge-side shade region S2 extends to the eaves side, the elongate simulation panel 5a is set to have a longer length in the gradient direction, and the first-row solar cell array 3a is separated from the snow stop rails 6. .
Therefore, even if sunlight inclined from the eave side to the ridge side is irradiated, the ridge-side shaded area S2 is accommodated in the ridge-side simulated panel 5b, and the ridge-side shaded area S2 completely overlaps the solar cell array 3b in the second row. Don't be. Therefore, a decrease in power generation efficiency of the second row solar cell array 3b is avoided.

  In addition, when the ridge side shade area | region S2 becomes the maximum, when solar altitude is the lowest, that is, sunlight is irradiated from a horizontal direction. Therefore, the length of the ridge-side simulated panel 5b in the gradient direction can be determined by measuring or calculating the ridge-side shaded region S2 when the solar altitude is the lowest.

  On the other hand, when the sunlight irradiating the roof R is inclined from the ridge side to the eaves side (see arrow D in FIG. 2), the snow stop rail 6 on the eave side roof surface with respect to the snow stop rail 6. Is projected (see the broken line D1 in FIG. 2), and an eaves side shade region S1 is generated.

Here, the eaves-side shaded area S1 is determined based on the three elements of the roof slope, the direction in which the photovoltaic power generation system 1 faces, and the latitude of the building in which the photovoltaic power generation system 1 is installed.
And in the assumed range, the case where the eaves side shade region S1 is the maximum is the case where the irradiation angle of sunlight is along the roof gradient. In this case, the solar cell array 3a in the first row It is practically difficult to set the length in the gradient direction of the eaves side simulation panel 5a so that the eaves side shade region S1 does not overlap.

  Therefore, when the length in the gradient direction of the eaves side simulation panel 5a can be set from the above three element conditions so that the eaves side shade region S1 does not always overlap the solar cell array 3a in the first row. This length is preferably set. According to this, even if sunlight inclined from the ridge side to the eaves side is irradiated, the eaves side shade region S1 fits in the eaves side simulation panel 5a, and the power generation efficiency of the solar cell array 3a in the first row is reduced This is because it can be avoided.

  On the other hand, it is practically difficult to set the length of the eaves-side simulated panel 5a in the gradient direction so that the eaves-side shaded region S1 does not overlap the first row of solar cell arrays 3a from the above three element conditions. In this case, by providing the eaves side simulated panel 5a, the solar cell array 3a in the first row is separated from the eaves side shade region S1, and the time and range where the eaves side shade region S1 overlaps can be reduced. Is preferred.

As described above, according to the snow retaining structure of the solar cell module 2 according to the present embodiment, the ridge-side shaded region S2 formed by projecting the snow retaining rail 6 does not overlap the solar cell module 2 at all. A decrease in power generation efficiency of the array 3b can be avoided.
Moreover, since the height of the side wall portion 8 of the snow stop rail 6 is such that snow can be reliably stopped, the snow on the solar cell array 3b in the second row can suppress snow falling to the eaves.

  Furthermore, according to the snow stop structure of the solar cell module 2 according to the present embodiment, the distance between the solar cell array 3b in the second row and the dust and dead leaves locked to the snow stop rail 6 can be increased, and the power generation efficiency Can be suppressed.

Although the embodiments have been described above, the present invention is not limited to the examples described in the embodiments.
For example, in the embodiment, the example applied to the roof-integrated solar power generation system 1 covering the roof base R1 has been described. However, the snow stop structure of the solar power generation panel of the present invention is formed on the roof base R1. The present invention can also be applied to a stationary solar power generation system 1 installed on a laid roof material. And, a stationary solar power generation system provided with a snow stop structure for a photovoltaic power generation panel according to the present invention. If it is 1, as described in the prior art, it is necessary to install a snow stopper installed on the roof material in order to prevent the snow on the second row solar cell array 3b from falling below the eaves. Absent. Therefore, it is not necessary to set the installation type solar panel at a distance of 500 mm or more from the snow stopper installed on the roof material, and the problem that the space for installing the installation type solar panel becomes small can be avoided.

In the embodiment, the snow stop structure including the simulated panel 5 and the snow stop rail 6 is provided between the first row solar cell array 3a and the second row solar cell array 3b. Is not limited thereto, and may be provided on the eaves side of the solar cell array 3a in the first row. In this case, since the solar cell array 3a is not provided on the eaves side of the snow stop rail 6, the simulated panel 5 disposed below the snow stop rail 6 is configured only by the ridge side simulated panel 5b. The side simulation panel 5a becomes unnecessary.
When the snow stop structure of the solar power generation panel is provided on the eaves side of the solar cell array 3a in the first row, the roof base R1 is prevented from being destroyed by the load of snow that is locked to the snow stop rail 6. Therefore, it is preferable to provide the snow stop rail 6 so as to be located on the ridge side with respect to the eaves beam R4.

In the embodiment, an example using the ridge-side simulated panel 5b in which the length in the gradient direction is set so that the ridge-side shaded region S2 does not always overlap the solar cell array 3b in the second row is given. However, the present invention is not limited to this.
For example, a ridge-side simulated panel 5b having a length in which the ridge-side shade region S2 overlaps the solar cell array 3b in the second row may be used. When such a ridge-side simulation panel 5b is used, the snow stop rail 6 and the second row solar cell array 3b are separated from each other, and the ridge-side shade region S2 overlaps the second row solar cell array 3b. It is possible to reduce the time and range in which the power generation is performed, and to suppress a decrease in power generation efficiency.

Moreover, although the case where the snow stop rail 6 long in the left-right direction is used as an example has been described in the embodiment, the present invention is not limited to this. For example, a snow stop rail having a short length in the left-right direction, a block snow stop, or a columnar snow stop may be used.
Further, when a short snow stop rail, a block snow stop, and a columnar snow stop are used, they may be arranged in a staggered manner. According to this, the snow accumulated on the snow stop rail or the like is likely to melt. In addition, the snow stopper of the present invention may be made of a transparent member.
