In the following description, the photovoltaic panels 101_a to 101_f are simply referred to as the photovoltaic panels 101 when they are not distinguished from each other. Further, the directions in which the plurality of photovoltaic power generation panels 101 are arranged are defined as the front-rear direction and the left-right direction, and the direction perpendicular to these directions is defined as the up-down direction.

The photovoltaic panel 101 is a panel that receives sunlight on its surface and generates electricity. The photovoltaic panel 101 is appropriately connected by electrical wiring (not shown), and the power generated by the photovoltaic panel 101 is supplied to a load or the like through this electrical wiring, a power conditioner (not shown), or the like. be done.

The photovoltaic panel 101 is also commonly referred to as a solar cell, solar panel, photovoltaic module, solar module, and the like. In this embodiment, an example in which six photovoltaic panels 101 are installed will be described.

Each of the photovoltaic panels 101 is arranged so that the surface faces upward and forward, and is arranged so that the surface is inclined with respect to the installation surface G by about 8 degrees, for example.

A so-called flexible solar panel is preferably employed for each of the solar panels 101 . A flexible solar panel is a photovoltaic panel that has a resin sheet instead of a glass plate on its surface and is surrounded by a flexible frame made of metal (for example, aluminum) and made of resin. Such a flexible solar panel is flexible and lighter than a glass panel having a glass plate on its surface. Note that the photovoltaic panel 101 may be a crystalline glass panel having a glass plate on its surface.

The size of each photovoltaic panel 101 may be determined as appropriate, but for example, the length is approximately 300 to 1000 mm, the width is approximately 2000 mm, and the thickness is approximately 3 to 5 mm. The weight of each photovoltaic panel 101 varies depending on the size, but is generally 2 to 6 kg.

The photovoltaic panel stand 102 is a stand for installing a plurality of photovoltaic panels 101 on the installation surface G in a row in the front-rear direction and the left-right direction. The installation surface G is a surface that is appropriately set as an area for installing the plurality of photovoltaic panels 101 . For the photovoltaic panel mount 102, a horizontal surface such as a flat roof surface is suitable as the installation surface G, for example.

Here, the peripheral portions of the plurality of photovoltaic panels 101 are the ends that are not adjacent to other photovoltaic panels 101 among the ends that constitute the front, rear, left, and right sides of each of the photovoltaic panels 101. It consists of

That is, in the present embodiment, photovoltaic panels 101_a and 101_b, photovoltaic panels 101_b and 101_c, photovoltaic panels 101_d and 101_e, and photovoltaic panels 101_e and 101_f are adjacent. Therefore, in the present embodiment, the right end portions of the photovoltaic panels 101_a and 101_d, the left and right end portions of the photovoltaic panels 101_b and 101_e, and the left end portions of the photovoltaic panels 101_c and 101_f are the plurality of photovoltaic panels 101 not included in the perimeter of Therefore, in the present embodiment, the peripheral portions of the plurality of photovoltaic panels 101 are the left ends of the photovoltaic panels 101_a and 101_d, the front and rear ends of the photovoltaic panels 101_a to 101_f, and the photovoltaic panels 101_a to 101_d. It consists of the right ends of 101_c and 101_f.

Here, "adjacent" means closer than a predetermined distance (for example, several centimeters). The distance that serves as a reference for determining whether the photovoltaic panels 101 are adjacent to each other is such that, for example, a wind that blows away the photovoltaic panels 101 passes through the gap between the photovoltaic panels 101 and reaches the photovoltaic panels 101. The distance is set such that the back surface of the 101 is not entered.

The support legs 103 have a length in the front-rear direction, and are attached to each of the photovoltaic panels 101 in pairs.

(Step 1).

Members constituting the support leg 103 include a seat plate 105, a first holding member 106, an inclination angle regulating member 107, a second holding member 108, and bolts B and nuts N for fixing them. The members constituting the cover 104 are front plates 129_a to 129_c, right side plates 130_a and 130_b, left side plates 131_a and 131_b, rear plates 132_a to 132_c, connecting plates 133_a to 133_c, and bolts B and nuts N for fixing them. including.

For example, if the installation surface G is a flat roof surface, it is generally necessary to carry various members that make up the solar power generation device 100 to the roof of the building. Since the photovoltaic panel 101 according to the present embodiment has the size and weight as described above, it can be easily transported using ordinary elevators and stairs used by residents. In addition, the members constituting the supporting legs 103 and the cover 104 also have a size corresponding to the photovoltaic panel 101 and are made of a lightweight material such as stainless steel. Easy to use and carry.

A pair of support legs 103 are attached to each of the photovoltaic panels 101 using the members carried in step 1 (step 2).

Here, the details of the process of attaching the support leg 103 are as follows.

A base end portion of a tilt angle regulating member 107 having a length is fixed to the rear end portion of the seat plate 105 with a bolt B and a nut N. As shown in FIG. After attaching the first holding member 106 to the front end portion of the seat plate 105 with the L-shaped pin 125 , the male screw portion 128 of the L-shaped pin 125 is fitted with a nut. As a result, the first holding member 106 is attached near the front end of the seat plate 105 so as to be rotatable about the L-shaped pin 125 .

By inserting the front end portion of the photovoltaic panel 101 into the holding portion 120 of the first holding member 106 , the front end portion of the photovoltaic panel 101 is held by the first holding member 106 . By inserting the rear end portion of the photovoltaic panel 101 located behind the first holding member 106 into the holding portion 120 of the second holding member 108 , the rear end portion of the photovoltaic panel 101 is held in the second holding member 108 . to hold. Then, after attaching the second holding member 108 to the tip of the inclination angle regulating member 107 with the L-shaped pin 125 , the male threaded portion 128 of the L-shaped pin 125 is fitted with a nut.

As a result, the front end portion and the rear end portion of the photovoltaic panel 101 are respectively held by the holding portions 120 of the first holding member 106 and the second holding member 108 arranged side by side in the front-rear direction. , a support leg 103 is attached to the photovoltaic panel 101 . Another support leg 103 is attached to the photovoltaic panel 101 in a similar manner. By repeating this, a pair of support legs 103 can be attached to each photovoltaic panel 101 .

Note that the method of attaching the support legs 103 to the photovoltaic panel 101 described here is merely an example, and may be changed as appropriate.

A reference position O is determined on the installation surface G (step 3). The reference position O is a reference position for arranging the photovoltaic panels 101, and is used to position the photovoltaic panels 101 placed at the left front, right front, left rear, right rear, and so on. The reference position O according to the present embodiment defines the position of the photovoltaic panel 101 arranged on the left front (see FIG. 12).

Using the reference position O, the photovoltaic panel 101 with the supporting legs 103 is placed (step 4).

Specifically, as shown in FIG. 12, a straight line L1 extending to the right with respect to the reference position O and a straight line L2 extending rearward from the reference position O are drawn. Since these straight lines L1 and L2 are not necessary once the photovoltaic power generation panel 101 is installed, they are preferably drawn with something that is easy to remove, such as chalk that disappears naturally with rain. First, the photovoltaic panel 101_a is arranged such that the left front corner matches the reference position O, and the front end and left end are along the straight lines L1 and L2, respectively.

Next, as shown in FIG. 13, the photovoltaic panel 101_b is arranged side by side on the right side of the photovoltaic panel 101_a so that the front end portion is aligned with the straight line L1. Subsequently, the photovoltaic panel 101_c is arranged side by side on the right side of the photovoltaic panel 101_b so that the front end portion is aligned with the straight line L1.

Two measuring aids 137 as shown in FIG. 14 are prepared. As shown in FIG. 15, the measurement aid 137 is arranged in a predetermined orientation so as to come into contact with the rear end of each of the support legs 103 of the photovoltaic panel 101_a. The photovoltaic panel 101 — d is arranged such that the left side thereof is along the straight line L2 and the front ends of the support legs 103 are in contact with the corresponding measurement aids 137 . In this way, by using the measurement aid 137, the photovoltaic panels 101_a and 101_d arranged in front and behind can be easily arranged at predetermined intervals. Of course, for example, the front and rear positions of the support leg 103 may be adjusted one by one using only one measuring aid 137 .

The photovoltaic panel 101 — e is arranged side by side on the right side of the photovoltaic panel 101 — d at a position similarly separated from the photovoltaic panel 101 — b by a predetermined distance using the measurement aid 137 . Then, the photovoltaic panel 101_f is arranged side by side on the right side of the photovoltaic panel 101_e using the measurement aid 137 at a position separated from the photovoltaic panel 101_c by a predetermined distance. As a result, the photovoltaic panels 101_a to 101_f with the support legs 103 are arranged (see FIG. 2, for example). At this time, each time one of the photovoltaic panels 101_a to 101_f is arranged, the adhesion area of the seat plate 105 of the support leg 103 attached to each may be adhered to the ground plane G.

They are secured together by sections 134-136.

As a result, the cover 104 is integrated into a planar shape, and even if the cover 104 is installed on an installation surface G, such as a flat roof, which is susceptible to wind, it is difficult for the wind to enter under the photovoltaic power generation panel 101 . As a result, when the wind blows, the photovoltaic panel 101 as a whole receives a positive pressure that presses it against the installation surface G, making it even more difficult to blow away.

Further, in the present embodiment, each of the plurality of right side plates 130_a and 130_b and the plurality of left side plates 131_a and 131_b includes face plates 129_a to 129_c and connecting plates 133_a to 133_c, or rear plates 132_a to 132_c and connecting plates 133_a to 133_c. , is fixed to

As a result, the cover 104 is integrated as a whole, and the wind is less likely to enter under the photovoltaic panel 101 . As a result, when the wind blows, the photovoltaic panel 101 as a whole receives a positive pressure that presses it against the installation surface G, making it even more difficult to blow away.

In the photovoltaic panel mount 102 according to the present embodiment, both the first holding member 106 that holds the front end and the like of the photovoltaic panel 101 and the second holding member 108 that holds the rear end and the like are is attached with an L-shaped pin 125 . As a result, the L-shaped pin 125 can be easily removed by removing the nut, and the L-shaped pin 125 can be rotated in the inserted state.

Therefore, if the front L-shaped pin 125 is removed, the photovoltaic panel 101 can be lifted by rotating around the rear L-shaped pin 125, and if the rear L-shaped pin 125 is removed, the front L-shaped pin 125 can be lifted. The photovoltaic panel 101 can be lifted by rotating around 125 . That is, with the photovoltaic panel mount 102 according to the present embodiment, the photovoltaic panel 101 can be easily lifted from either the front or the rear.

Normally, the photovoltaic panel 101 may require work behind the photovoltaic panel 101 for electrical wiring connection, maintenance, and the like. According to this embodiment, the photovoltaic panel 101 can be easily lifted from either the front or the rear depending on the situation of the installation site. Therefore, it is possible to facilitate the work on the back side of the photovoltaic power generation panel 101, such as connection of electric wiring and maintenance.
