ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fixing member for fixing a solar cell module or a roofing member with no solar cell to a prescribed installation face, a solar cell module array using said fixing member, and an execution method for installing a solar cell module or a roofing member with no solar cell using said fixing member.
2. Related Background Art
In general, in the installation of a solar cell module, particularly a roofing member integral type solar cell module on a roof face, it is necessary to establish a prescribed space for connecting cables extending from the solar cell module. This is due to the following reason. For instance, as shown in
FIG. 1
, when a solar cell module-integrated roofing member for a stepping roof (Bermuda-type roof) is installed in the ordinary manner, the rear face of a ridge side end portion of the solar cell module unavoidably touches the surface of the sheathing roof board, whereby the passage necessary for electrically connecting the neighboring solar cell modules arranged in the water flow direction is blockaded.

In the case of a solar cell module-integrated roofing member (
2201
) for a ribbed seam roof having upward bent opposite end portions as shown in
FIG. 2
, since a junction box
2202
is provided at the rear face of the roofing member
2201
, the bottom of the roofing member
2201
must be raised using a spacer

In order to eliminate the foregoing disadvantages, there are known such manners as will be described below.
(1) A manner as shown in
FIG. 3
in which a predetermined portion of a sheathing roof board
2301
is cut off to form a wiring gutter
2302
having a passage
2305
for a cable to pass through. Also, a manner as shown in
FIG. 4
in which a predetermined portion of a sheathing roof board
2401
is cut off and a sheathing roof board having an area corresponding to the cut-off sheathing roof board portion is fixed onto a main frame
2403
to form a passage
2404
for a cable to pass through.

, reference numeral

(2) A manner as shown in
FIG. 2
(which has been explained before) or in
FIG. 5
in which a spacer (
2203
,
2504
) made of a wood or metal is fixed on a sheathing roof board (
2207
,
2506
) and a solar cell module (
2201
,
2501
) is fixed on the spacer to form a space for a cable to pass through.

(3) A manner in which a backing member (a heat insulating member) is arranged under the rear face of a solar cell module to form a space between the solar cell module and the backing member which allows a cable to pass through the space.
(4) A manner in which a solar cell module is curving-processed to have a corrugated form and a cable is passed through a space of the corrugated form.
However, the above-described manners have disadvantages as will be described below.
Any of the manners described in the above (1) can be employed only in the case of a gable roof (a rectangular roof) where cable connection positions in a shed direction on the roof face are constant.
For instance, in the case of a gable roof as shown in
FIG. 6
in which the opposite end portions of solar cell module strings are situated on verge portions, it is sufficient that one or two cable-wiring passages
2605
are provided. However, in the case of a hip roof in a trapezoid form as shown in
FIG. 7
where a plurality of solar cell modules are arranged in stepwise arrangements, their cable connection positions in a water flow direction are different from each other depending upon the arrangement stage. As a result, an appropriate cable-wiring gutter is necessary for each arrangement stage. This situation is disadvantageous in that the wiring gutter is required to be specifically designed for each arrangement stage, extra work is necessary to properly position the wiring gutters, and expenses rise accordingly.

an installation face on which solar cell modules are installed, reference numeral

2704
a connection cable.
Further, any of the manners described in the above (1) includes a step of cutting the sheathing roof board prior to installing the solar cell modules. As a result, there are disadvantages such that it takes a certain period of time to complete this step, and attention must be directed to the weathering problem which will be caused due to cutting the sheathing roof board. In addition, in the case where the wiring gutter is provided, an extra expense for providing the gutter is incurred.
The manner described in the above (2) is advantageous in that when the solar cell modules are installed, spaces are formed under the rear faces of the solar cell modules on the entire roof face. As a result, the cable connection positions in a water flow direction can be designed at optional locations. This is not restricted depending upon the form of a roof, i.e., gable roof or hip roof. However, there are disadvantages such that it is necessary to fix spacers to the sheathing roof board prior to installing the solar cell modules, whereby extra execution work and extra expenses are incurred. In addition, when using an underplate to join solar cell modules for stepping roofing which are arranged so as to neighbor with each other in a direction to the main frame and also to prevent a weathering problem, when the underplate is positioned on the spacers, portions of the underplate which are situated on the spacers protrude somewhat to mar the exterior appearance.
The manner described in the above (3) in which the cable connection space is formed by using the backing member under the rear face of the solar cell module has a disadvantage in that extra expenses are required for the backing member.
The manner described in the above (4) in which the solar cell is curving-processed has a disadvantage in that extra expenses are required for the solar cell module to be curving-processed.
SUMMARY OF THE INVENTION
A principal object of the present invention is to eliminate the foregoing disadvantages found in the prior art and to provide a fixing member which enables one to desirably install a solar cell module with a diminished number of execution steps and at a low installation cost and which enables one to establish a space which allows a connection cable extending from said solar cell module to pass through.
Another object of the present invention is to provide a solar cell module in which the above fixing member is used.
A further object of the present invention is to provide an execution method for installing a solar cell module using the above fixing member.
