DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a solar cell array according to the present invention will be described in detail based on the drawings schematically shown. FIGS. 1A and 1B show a plan view and a side view of a solar cell module M constituting a solar cell array. FIG. 2 shows a state in which a solar cell array A formed by connecting and arranging a plurality of solar cell modules M is arranged on a part of a roof Y of a building. 3 is a partially exploded perspective side view of the solar cell array A, and FIG. 4 is a perspective side view of the solar cell array A.
[0010]
As shown mainly in FIG. 1, the solar cell module M is detachable from a solar cell main body 1 for generating power in a case (frame body) 2 that is formed in a frame shape in three directions and is attached to the roof at one end. Is housed in. The overall shape and size of the solar cell module are matched to the shape and size of a general roof tile.
[0011]
Here, the case 2 is made of a metal material that is lightweight and excellent in strength, such as aluminum. The solar cell body 1 is provided with a light-transmitting substrate such as glass or resin on the light-receiving surface, and a sealing material made of resin or the like in which a large number of solar cell elements are accommodated is attached to the light-transmitting substrate. Yes. As the solar cell element, for example, a single crystal or non-single crystal material such as a compound semiconductor made of silicon-based semiconductor or gallium arsenide is used, and is electrically connected in series and / or in parallel.
[0012]
Further, on the light receiving surface side of the solar cell main body 1, when the solar cell array A is configured, the surface side locking member 6 that can be engaged with the adjacent solar cell module is lightweight and excellent in strength such as aluminum. It is formed in a cross-sectional L shape by a metallic material or the like. Further, a rear surface side locking member 7 having an L-shaped cross section that can be engaged with another adjacent solar cell module or a locking member 11 disposed on the roof Y is provided at the front end of the solar cell body 1. It is formed of the same material as the locking member 6 and is detachably attached to the solar cell body 1.
[0013]
Further, reference numeral 3 in FIG. 1 denotes a support rotation portion formed in a semi-cylindrical shape, and is supported by a support body 13 attached to the roof so as to be rotatable at an angle exceeding 90 ° with respect to the ground. The support 13 is made of a metal material such as aluminum that is light and excellent in strength, and includes a convex portion that firmly holds the support rotating portion 3 and is fixed to the roofing material 15.
[0014]
Thus, since the solar cell module can be rotated at an angle exceeding 90 ° with respect to the ground, and the solar cell body 1 can be attached to and detached from the case 2, wiring work is easy and maintenance is possible. -Inspection work can be done very easily. Reference numeral 9 in the drawing denotes a cable accommodated in the back side locking member 7, which is electrically connected to the terminal box 8 so that the output of the solar cell module M can be taken out.
[0015]
As shown in FIG. 2, the solar cell array A of the present invention is formed by stacking a plurality of solar cell modules M including solar cells that convert sunlight into electric energy on a roof Y of a building. For example, it is installed on the roof surface of a building such as a general household, and the electric load in the building can be reduced.
[0016]
As shown in FIG. 3 and FIG. 4, the solar cell module groups M <b> 1 to M <b> 4 that constitute the solar cell array A are arranged on the support 13 disposed on the roof Y. A part of the support rotating part 3 is rotatably attached to the support body 13 fixed on the roof Y, and the other peripheral part thereof is placed on the surface of the adjacent solar cell module group or tile K1. . Further, at the upper end of the solar cell array A, one end of the roof tile K2 is placed on the light receiving surface side of the solar cell module group M4. Thus, in the solar cell array of the present invention, a part of the periphery of the solar cell module group is rotatably attached, and the other peripheral part of the solar cell module group is tiled on the surface of the adjacent solar cell module group. It is made to be done.
[0017]
As described above, when the solar cell module groups are tiled on the front surface side and the back surface side of the solar cell module group, the front surface side of one solar cell module group and the back surface side of the other solar cell module group, respectively. Due to the locking members 6 and 7 engaged with each other, the solar cell module group does not float due to wind pressure or the like.
[0018]
Moreover, as shown in FIG. 4, in the solar cell module group M1 arrange | positioned at the lower end part of the solar cell array A, the lower end part 7a of the locking member 7 and the L-shaped cross section provided on the roof Y are provided. By engaging with the lower end portion 11a of the locking member 11, the solar cell module group M1 is prevented from being lifted as much as possible. Note that the locking member 11 is also made of a metal material that is lightweight and excellent in strength, such as aluminum.
[0019]
FIG. 6 shows how the solar cell modules are connected in the solar cell module group in the solar cell array A of FIG. Further, an enlarged view of P1 in FIG. 6 is shown in FIG. 7, and an enlarged view of P2 is shown in FIG. In the figure, MA and MB are adjacent solar cell modules, and DM is a dummy module.
[0020]
As shown in FIGS. 6 and 7, a long connecting member 21 that also serves as a joint cover is disposed between the solar cell module MA and the solar cell module MB adjacent thereto. At the center, ridges 21a and 21b are formed that fit into the protruding grooves 22a and 22b of the frame member 23 of both solar cell modules. Further, a flange portion 21c is formed on the roof base side of the connecting member 21 so that rainwater can flow and the roof base side can be waterproofed. Moreover, since the collar part 21c of the connection member 21 is located inside a solar cell module rather than the frame member 23, the further waterproofing effect of rainwater can be anticipated.
[0021]
Similarly, as shown in FIGS. 6 and 8, a connecting member 31 similar to the above is also disposed between the solar cell module MA and the dummy module DM adjacent thereto, and the frame member of the solar cell module MA is provided. 32. Furthermore, the convex part 40 formed in the edge part of the dummy module DM faces the collar part 31c similar to the said structure, and the waterproof effect is heightened.
[0022]
In the solar cell array, as shown in FIG. 5, each solar cell module group can be attached to the support 13 provided on the roof Y so as to be rotatable by about 180 °. As a result, wiring work, maintenance / inspection work, etc. can be performed more easily, and the connection between the solar cell module groups can be confirmed and easily performed. Moreover, even if there is a mistake in the connection or the case where construction is re-executed, correction can be made in a very short time.
[0023]
【The invention's effect】
As described above, according to the solar cell array of the present invention, after wiring the solar cell modules and the solar cell module groups while fixing the solar cell modules and the solar cell module groups one by one to the roof surface, The connection state can be confirmed easily and quickly visually.
