Description

  The present invention relates to a solar power generation device such as a solar cell module that generates power using solar energy, and more particularly to a solar power generation device installed on a flat roof using a mount.

  2. Description of the Related Art In recent years, a solar power generation apparatus using a solar cell module in which a plurality of solar cell elements that convert sunlight into light are connected and using a roof of a house as a power generation unit has become widespread. In particular, buildings such as buildings and condominiums, factories, warehouses, etc. have a large area of the roof, so many solar power generators are installed on the roof. In connection with this, various photovoltaic power generation apparatuses corresponding to a flat roof shape have been proposed.

  For example, in Patent Document 1 and Patent Document 2, a light receiving surface of a solar cell module is inclined and installed on a frame, and a cover wall that closes a gap opened around the solar cell module is provided so that the solar cell module is blown. There has been proposed a solar cell module mount configured such that the wind pressure to be applied can be used for the pressing force of the solar cell module.

  However, since the pedestal described in Patent Document 1 and Patent Document 2 has the peripheral side surface of the solar cell module closed by the cover wall, heat is trapped in the enclosed space, and the pedestal itself and thus the solar cell module is cooled. There was a problem that it was difficult. In general, a solar cell module is vulnerable to heat, and power generation efficiency decreases as the temperature rises, so cooling performance has been an important issue. In addition, rainwater that entered from a slight gap remained on the flat roof in the closed space forever, and the drainage was poor in the closed space.

  The present invention has been made in view of the above problems, and provides a photovoltaic power generation apparatus capable of ventilating a closed space in a cover wall in a photovoltaic power generation apparatus in which the periphery of a solar cell module is blocked by a cover wall. With the goal.

  For this reason, the solar power generation device of the present invention is a pedestal that is placed on a flat roof and supports the solar cell module, and a solar power generation device in which a cover wall is provided on the peripheral side surface of the solar cell module installed on the gantry in an inclined manner. The first feature is that the cover wall includes at least a pair of vertical walls facing each other, and the vertical walls include a waterproof ventilation louver.

  The waterproof ventilation louver is a louver in which a plurality of blades are arranged side by side in a lattice shape and can be ventilated by a gap between the blades, and the blades are substantially cross-sectionally shaped at substantially the center in the width direction. Are formed in an arc shape that bulges toward the outside, and arc-shaped surfaces having different bending directions are provided at the refraction point of the blade, and the cross section is L-shaped outside the refraction point. A plurality of blades having an intermediate groove member integrally formed and having a lower edge groove member having a cross-section of an inverted L shape on the inner side of the lower end edge portion of the character-shaped portion. They are superposed in the vertical direction so that the lower edge member of the other vane plate is located below the intermediate groove member of the plate, and are arranged in parallel with each other with a substantially square-shaped gap between the vane plates. This is a second feature.

  Since the photovoltaic power generation device of the present invention has a waterproof ventilation louver on a vertical wall, it can ventilate a closed space in the photovoltaic power generation device and can prevent intrusion of rainwater blown with the wind. . Moreover, the secondary effect which can prevent that heat accumulates in closed space and can prevent deterioration of a solar cell module is acquired.

It is a perspective view which shows the other Example of the solar power generation device which concerns on this invention.

  Hereinafter, the solar power generation device 1 according to the first embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. The solar power generation device 1 of the present invention has a plurality of solar cell modules P arranged vertically and horizontally on a mount installed on a flat roof, and is supported and fixed in an inclined state, and a wall body is provided around the solar cell module P. A waterproof ventilation louver is provided on the wall. In the present invention, the front surface of the photovoltaic power generation apparatus 1 refers to the lower left direction in FIG. 1 and the left direction in FIG. 2, and the rear surface refers to the upper right direction in FIG. 1 and the right direction in FIG. .

  As the material of the gantry, any material that is generally used for the gantry can be used. Examples of such materials include metal materials and alloy materials such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plates, alloy plated steel plates, or synthetic resin materials such as vinyl chloride resins and polycarbonate resins. An alloy-plated steel sheet is preferable from the viewpoint of lightness and rigidity. As shown in FIG. 2, the gantry is provided with a plurality of support bars 11 in which a plurality of columns 12 having different heights are erected, and these are connected by horizontal bars 13, and a fixed bar 14 to which the solar cell module P is fixed is provided. It is provided at an upper portion of the horizontal rail 13 in an inclined manner and integrated. In the present invention, the support 12, the horizontal beam 13, and the fixed beam 14 are formed by bending an alloy-plated steel plate into a U shape, but the present invention is not limited to this, and its own weight, wind pressure, etc. The bent shape can be selected according to the load.

  The plurality of support columns 12 are provided on the support bar 11 at different heights so that the solar cell module P has a predetermined inclination angle. The inclination angle and the height of the support columns 12 are determined by the photovoltaic power generator 1. It is determined by the solar radiation conditions of the installed roof. As shown in FIG. 2B, the support bar 11 is formed such that the cross-sectional shape in the short direction is a convex shape, and a ground contact area is secured. Further, as shown in FIG. 2A, the support bar 11 is configured such that its end protrudes from the end of the fixed bar 14, and a hole is formed in the end of the support bar 11. It has been drilled. The hole can be fixed to the flat roof through a wire or the like (not shown) in this hole, and a side wall cover 23 described later is provided perpendicular to the installation surface G. Therefore, the side wall cover 23 receives wind pressure and the photovoltaic power generator 1 itself Can be prevented from moving horizontally.

  The solar power generation device 1 is provided with a cover wall that attaches the solar cell module P to the frame assembled by the above configuration and closes an open gap from the periphery of the solar cell module P to the installation surface G. As shown in FIGS. 1 and 2, the cover wall includes a front wall cover 21, a rear wall cover 22, and a pair of side wall covers 23. More specifically, the cover wall hangs down from the end of the solar cell module P toward the installation surface G, and the front wall cover 21 and the rear wall cover 22 that are inclined from the end of the solar cell module P toward the installation surface G. The side wall cover 23 provided with the waterproof ventilation louver 31 is fixed to the support bar 11 and the fixed bar 14 (inclination angle = 0).

  The front wall cover 21 covers the front edge of the upper surface of the solar cell module P and is inclined toward the outside, and the rear wall cover 22 covers the rear edge of the upper surface of the solar cell module P and is inclined toward the outside. A cover is provided along the end of the support bar 11 so as to cover the fixed bar 14. As shown in FIGS. 1 and 2B, the side wall cover 23 is a vertical wall that covers the left and right edge portions of the upper surface of the solar cell module P and the fixing bar 14 and hangs down toward the installation surface G. A bent portion 23a is formed to ensure the above. The front wall cover 21, the rear wall cover 22, and the side wall cover 23 are formed by bending an alloy plated steel plate.

  The side wall cover 23 is provided with a waterproof ventilation louver 31 so that the space Q in the frame closed by the cover wall can be ventilated. As shown in FIG. 3, the waterproof ventilation louver 31 includes an outer surface 313 in which a plurality of horizontal blade plates 312 are integrally connected to an aluminum sash frame 311, and an inner surface 314. It is set as the structure attached to the side wall cover 23 in the state which the side surface 314 faces in the space Q in a mount frame. The horizontal blade plate 312 is made of an aluminum plate, and is inclined to the lower outside, and is provided with a plurality of horizontally elongated ventilation holes 315 at regular intervals in the vertical direction.

  Reference numeral 316 denotes a vertical blade. The vertical blade plate 316 has a substantially U-shaped cross section in the width direction (internal / external direction) of the frame body 311, and the first arcuate surface 317 having different bending directions from each other at the refraction point 316 a of the vertical blade plate 316 and A second arcuate surface 318 is formed continuously. Further, an intermediate groove member 319 extending from the second arcuate surface 318 and having an inverted L-shaped cross section is integrally formed outside the refraction point 316a, and a cross section is formed at the lower end edge of the second arcuate surface 318. An L-shaped lower edge groove member 320 is integrally formed. That is, the vertical blade plate 316 is constituted by a mold material having a continuous cross-sectional shape including the first and second arcuate surfaces 317 and 318, the intermediate groove member 319, and the lower edge groove member 320. And it is supposed that the outside air is ventilated from the outside to the inside with a gap 321 (ventilation passage) between the vertical blade plates 316.

  That is, the vertical blade plates 316 configured as described above are arranged in parallel to each other and fixed in the rectangular frame 311. At this time, each vertical blade plate 316 is positioned so that one intermediate groove member 319 overlaps the other lower edge groove member 320 between adjacent ones, and the inner surface of one vertical blade plate 316 is disposed. And an outer surface of the other vertical blade plate 316 so that a gap (air passage) 321 having a substantially square cross section is formed.

  Since each vertical blade plate 316 is formed in an arc shape having a substantially square cross section at the center in the width direction and bulging outward, centrifugal force is applied to the air flowing between the vertical blade plates 316. The resistance of circulating air can be greatly reduced. That is, since the plurality of vertical blades 316 arranged in the vertical direction have a substantially cross-sectional shape in the width direction and are provided with two arcuate surfaces 317 and 318, wind and rain from the outside follows each arcuate surface. Can flow smoothly and provide adequate ventilation. Furthermore, a groove is formed in the vertical direction by the intermediate groove member 319 and the lower edge groove member 320 at the back and end portions of these arcuate surfaces 317 and 318, and these grooves prevent entry of wind and rain from the outdoors to the indoors. It can catch raindrops, collect them, and let them flow down.

  In the solar power generation device 1 configured as described above, outside air freely passes through the gap 321, and rainwater that naturally falls from above is received by the intermediate groove member 319. On the other hand, the rainwater blown with the wind first collides with the bulging portion of the first arcuate surface 317 and is mostly received in the intermediate groove member 319. Rainwater that has passed over the member 319 collides with the bulging portion of the second arcuate surface 318 by centrifugal force when the wind direction is bent following the arcuate surfaces 317 and 318, and is received by the lower edge groove member 320 and flows down. Therefore, it is possible to reliably prevent rainwater from entering the inside (that is, the closed space Q in the cover wall) from the outside of the solar power generation device 1 and to ventilate the closed space Q.

  Note that the gist of the present invention is that a solar power generation device in which the periphery of the solar cell module is closed with a cover wall is provided with a waterproof ventilation louver on at least a pair of vertical walls, thereby ventilating the closed space in the solar power generation device. This is a point that has a waterproof function and can be freely changed without departing from the scope of the present invention. Therefore, for example, as shown in FIG. 4, solar cell modules P may be provided on the front surface and the rear surface so as to be symmetrical at the vertex T. Further, for example, not only the side wall cover but also the front wall cover and the rear wall cover may be vertical walls, and a waterproof ventilation louver may be provided on them.
