摘要:
A terminal exposed from an edge of a solar cell module to extract power from a photovoltaic element, and a conductive member of a cable are electrically connected to each other. The solar cell module has at least photovoltaic elements and a cover member that covers the photovoltaic elements. This electrical connecting portion is located in a fixing member that fixes the cable and the solar cell module to each other. The long-term reliability of the terminal extraction portion is improved, and the solar cell module can be installed easily.

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.

A solar cell module includes a front member placed at a light-incident side of the module; a sealing member having an exposed section that is not covered with the front member; solar cell elements that are sealed with the sealing member and covered with the front member; and an electric device, stored in a housing, for extracting electricity generated by the solar cell elements. The housing is fixed on the exposed section and is located at a light-incident side of the module.

Provided is a solar cell module having a reinforcing member integrally stacked by means of a covering material on a rear surface of a solar cell panel having a photovoltaic element that performs photoelectric conversion, wherein a bent portion is formed in each of opposing end portions of the reinforcing member, an output wire member having conductivity is extended from an output portion of the photovoltaic element disposed on a light-receiving surface side of the solar cell panel along a surface of the bent portion so as to get over the bent portion, and a tip end of the extended portion of the output wire member is exposed out of a surface opposite to the reinforcing member of the covering material to form an output terminal portion. Thereby, there is provided a solar cell module that is improved in the area efficiency and weather resistance as well as the workability of electrical wiring and electrical connection during manufacturing and is inexpensive.
