Description

TECHNICAL FIELD The present invention relates to a method for installing a panel unit having photovoltaic cells arranged in a strip-shaped structure such as a wall of an expressway.

Conventionally, on both sides of an expressway, walls for sound insulation and soundproofing are sometimes arranged. Furthermore, there is also a technique of attaching a photovoltaic cell panel to this wall to utilize solar energy (see Patent Document 1, for example). In this document, a plurality of solar cell panels are installed in N stages in the height direction in the plane of the curved portion that constitutes the sound insulation wall, and these panels are connected to collect power.

JP-A-9-53211

However, when a panel of photovoltaic cells is provided on a wall or a curved portion thereof, the light-receiving surface of the panel becomes a substantially vertical surface, resulting in poor power generation efficiency and a small amount of power generation.
Furthermore, when attaching a panel to an existing structure, it is necessary to perform the attachment work so as not to interfere with the use of the structure. For example, in the case of an expressway, the installation work must be completed in a short time because the expressway is closed during installation.

A panel unit installation method that solves the above problems is arranged between a first support column and a second support column among a plurality of columns arranged at regular intervals, and has a first side, a second side, a third side and a third side. In a method for installing a panel unit having four sides, the panel unit includes a panel portion having a plurality of rectangular plate-shaped photovoltaic cells, and the longitudinal directions of the photovoltaic cells are the third side and the fourth side. The photovoltaic cells are arranged in parallel with the sides and inclined in a direction of rotation about support shafts fixed to both ends in the longitudinal direction of the photovoltaic cells, Two sides face each other and have a first distance that can be attached to the first support and the second support, and the third side and the fourth side face each other and the first support. a first mounting direction in which the first side is perpendicular to the plurality of pillars according to the installation location of the panel unit, and a first mounting direction having a second distance that allows attachment to the pillar and the second pillar ; It is mounted in one of the second mounting directions in which the first side obtained by rotating the first mounting direction by 90 degrees is the horizontal direction.

ADVANTAGE OF THE INVENTION According to this invention, the panel unit which has a photovoltaic cell can be efficiently attached in consideration of power generation efficiency.

(Pretreatment for installation work)
First, a management device is used to create an installation instruction that defines the installation direction of each panel unit 10 and the angle of the photovoltaic cell 23 .

The management device is a computer terminal with an input and an output. The input unit is a keyboard, pointing device, or the like, and the output unit is a display or printing device. The management device stores the ratio (solar intensity) for each azimuth/tilt angle with respect to the maximum value of integrated solar intensity for the year. In this solar radiation intensity, 0 degrees (due south), 45 degrees (southeast, southwest), 90 degrees (due east), 135 degrees (northeast, northwest), and 180 degrees (due north) are used as azimuths. In addition, 0 degree (horizontal), 10 degrees, 20 degrees, 30 degrees, and 40 degrees are used as the tilt angle. Note that 0 to 40 degrees due north is 0 to -40 degrees due south.

The management device acquires, via the input unit, obstacle information against solar radiation, such as highway W1 in the area where the panel unit 10 is installed, map information of the surrounding area, and height information of surrounding buildings. The management device specifies the installation locations (coordinates of the installation positions) of the panel units 10 at predetermined intervals on both sides of the highway W1 on this map. Furthermore, the management device identifies the orientation of the layout surface of each panel unit 10 at the identified installation location. Further, the management device acquires shadow formation information according to the shadow time of the building B1 adjacent to the highway W1 from the acquired obstacle information.

Then, the management device uses the orientation and shadow formation information of the installation surface and the stored solar radiation intensity to determine the installation direction and inclination (within the range of 0 to 40 degrees) that maximizes the power generation efficiency of each panel unit 10. 10 degrees) is specified for each panel unit 10 . Then, the management device generates mounting instruction data that associates the installation location of each panel unit 10, the mounting direction (first mounting direction or second mounting direction) of the panel unit 10, and the set angle. The management device prints an installation instruction based on the installation instruction data. This mounting instruction contains a list describing the installation location, mounting direction, and setting angle for each panel unit 10 .

For example, if the orientation of the installation surface is south (north), there is no building on the south side, and the maximum solar radiation intensity is 30 degrees at this position (latitude), the first installation direction and the set angle are 30 degrees at this installation location. Include degrees in installation instructions.
In addition, even if the orientation of the installation surface is south (north), if there is a building on the south side, sunlight enters the panel unit 10 only from the due east side, and the maximum solar radiation intensity at this latitude is 10 degrees, , at this installation location, include a second mounting direction and a set angle of 10 degrees in the mounting instructions.
Furthermore, when the orientation of the installation surface is east (west) and there is no obstacle such as building B1 in the east and west, the first installation direction and the installation angle of 0 degrees to 10 degrees are included in the installation instructions.
Furthermore, even if the orientation of the installation surface is east (west), if there is an obstacle such as building B1 on the east and west and the solar radiation is blocked, the second installation direction and the setting angle of 30 degrees are specified in the installation instructions. include.

In this case, the worker arranges the panel unit 10 to be mounted in the mounting direction (first mounting direction or second mounting direction) specified in the mounting instruction at the installation position of each panel unit 10 . Then, the bolts 30 are passed through the through holes 16 aligned with the screw holes h1 of the columns C1 and screwed into the screw holes h1 of the columns C1 to fix the panel unit 10 to the two columns C1.

Next, the adjustment hole 27h, which is the angle set in the installation instruction sheet, is aligned with the engagement hole 26a of the sheath tube 26, and the fixing jig 29 is passed through the adjustment hole 27h and the engagement hole 26a. As a result, the inclination of each photovoltaic cell 23 of the panel section 20 can be adjusted to the set angle at once.

(4) In this embodiment, the panel unit 10 has a plurality of photovoltaic cells 23 with a length L3 within a range not exceeding the construction gauge. As a result, even if the photovoltaic cell is tilted from the vertical to increase the power generation efficiency, it is possible to prevent the construction gauge of the road from being exceeded.
(5) In this embodiment, the panel unit 10 has a plurality of panel sections 20 . As a result, the length in the longitudinal direction of the photovoltaic cell 23 having the length L3 that does not exceed the construction gauge can be shortened. Furthermore, a panel unit 10 in which a plurality of panel sections 20 are integrated can be attached.

(6) In the present embodiment, the management device identifies the installation direction and inclination that increase the power generation efficiency, using the orientation of the placement surface of the installation location of the panel unit 10, the shadow formation information, and the solar radiation intensity. Then, the management device outputs a mounting instruction sheet including mounting instruction data that associates the installation position, mounting direction, and set angle of each panel unit 10 . As a result, using the installation instructions, the panel unit 10 can be installed efficiently while considering the influence of the shadow of the building B1 or the like so that the installation direction and inclination increase the power generation efficiency.

(7) In the present embodiment, the through holes 16 of the mounting member 15 of the panel unit 10 are aligned with the post C1 having the threaded hole h1 formed in the flange on the road side, and the bolts 30 are mounted.

The mounting direction and inclination of the panel unit 10 are not limited to the case where the power generation efficiency is maximized, and it is sufficient if the mounting direction and angle can be set according to the incident direction of sunlight. For example, the mounting direction and inclination of each panel unit 10 may be set so that the amount of power generated by the entire mounted panel unit 10 is less fluctuated. In this case, the management device determines the installation direction and inclination of each panel unit 10 so as to minimize fluctuations in the amount of power generation by using shadow formation information and solar radiation intensity according to the time of shadows cast by adjacent buildings. Identify according to

- The panel unit 10 of the above embodiment has a plurality of photovoltaic cells. A sound insulation sheet may be further attached to the panel unit 10 .
