Problems solved by technology

[0004] 1. Since the solar cell module integrated with the cover material cannot be cut off, the installation location of the solar cell module integrated with the cover material is limited
For example, for a ridge roof, the allowable setting range is limited from the eaves to the ridge, so many covering materials integrated solar cell modules cannot be set
[0005] 2. When the solar cell modules integrated in the covering material are not set regularly, the appearance of the roof is destroyed
[0006] 3. Difficulty in electrical connection
For this reason, many solar cell modules cannot be configured (problem 1 mentioned above)
In addition, since the solar cell modules are irregularly configured (Fig. 5), the appearance is not very good (problem 2 mentioned above)
In the arrangement method shown in Fig. 4 and Fig. 5, because the distance between the solar cell modules 401 integrated in the covering material on adjacent rows is very large, many connection cables 406 are needed to connect the connection points of the solar cell modules, resulting in a low Execution efficiency and high cost (problem 3 mentioned above)

Abstract

To optimally arrange roofing material integrated solar battery modules having a rectangular form and same size on a roof setting surface, an arrangement range in which the solar battery modules can be arranged on the roof setting surface is determined. An arranging direction of the solar battery modules is determined. The number of solar battery modules which can be arranged almost horizontally in a line in the determined arranging direction and within the arrangement range is calculated. Solar battery modules of a line in a number not more than the calculated number are combined to form a solar battery module group. The solar battery module groups are arranged to set a center of the solar battery module group within the determined arrangement range and near a line almost vertically dividing the surface into two parts. The above operations are repeated a number of times corresponding to the number of lines of solar battery module groups which can be vertically arranged in the determined arranging direction and within the arrangement range.

Description

technical field [0001] The present invention relates to a method of arranging solar cell modules and a solar cell module array, and in particular to a method of arranging solar cell modules having a rectangular shape and the same size on an installation surface such as a roof, and a solar cell module array installed by the arranging method . Background technique [0002] As a method of arranging covering materials on the roof surface, especially stepping roof or Bermuda-type roofing materials, the method of two lap joints (Fig. 2) or the Mechigai covering method / offset covering method ( image 3). The advantage of these covering material configuration methods is that a good appearance can be obtained, because the covering material 201 is offset with a predetermined joint from the eaves (eaves) 202 as the bottommost edge of the roof to the ridge (ridge) 203 as the topmost edge of the roof. Shift width 205 configuration. In these disposition methods, for weathering, the join...
