A solar cell array having an exposed electroactive portion is connected to a system power supply through an insulation transformer, a ground-fault interrupter is provided between the solar cell array and the system power supply, and a ground-fault detector is provided at the grounded line of the solar cell array. A set current value at which the ground-fault detector judges a ground-fault is larger than an amount of a set current value at which the ground-fault interrupter interrupts a circuit. The insulation transformer is provided between the solar cell array and the system power supply. Owing to such structure, the present invention aims at the simplification of environment-resistive coating having a large ratio of cost of the solar cell, and the simplification of insulating coating of members that connect the solar cells in series and parallel, and provides a photovoltaic power generation system which does not stop by the leakage current of the electroactive portion in connection with such simplification of the environment-resistive coating and insulating coating.

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 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.

A solar-cell module having a photovoltaic device, a reinforcing sheet for reinforcing the photovoltaic device and a covering material which seals the photovoltaic device on the reinforcing sheet is bent at a region between the border of the photovoltaic device and the outer edge of the reinforcing sheet, where the reinforcing sheet is covered with the covering material at the part extending from the border of the photovoltaic device up to the bent portion closest thereto, or the covering material is, at the margin thereof, made to have a thickness cross-sectionally smaller as it extends farther from the border of the photovoltaic device, provided that the reinforcing sheet is not covered at the outward margin thereof with the covering material. The covering material which covers the photovoltaic device of the solar-cell module is peel-resistant.
摘要:
A solar cell module comprises a front surface member disposed on a front surface side of a photovoltaic element having at least a semiconductor photoactive layer on a flexible substrate, a back surface member disposed on a back surface side of the photovoltaic element, and a sealing material interposed therebetween. The flexible substrate of the photovoltaic element has a plurality of substantially parallel surface grooves on a surface thereof at the semiconductor photoactive layer side of the flexible substrate. At least one portion of the solar cell module is processed to deform in such a direction that strain generated in a substantially parallel direction to the surface grooves is applied to the photovoltaic element. In this way, a solar cell module can be subjected to deformation-processing that prevents, to the extent possible, cracks in the semiconductor photoactive layer of the photovoltaic elements; in other words, deformation-processing can be achieved without influencing electrical characteristics. A method of producing such a solar cell module is also disclosed.
摘要:
A solar cell module comprises a photovoltaic device having a flexible substrate. The photovoltaic device has a strain at least partly in the planar direction of the flexible substrate, and the strain is not greater than a critical value at which the photovoltaic device cracks. The solar cell module may further comprise a strain holding means for holding the strain. A deformable region where the photovoltaic device can be deformed when a region embracing the photovoltaic device is worked is defined so that a great variety of solar cell modules having a high reliability, also taking account of manufacture, can be designed with good efficiency.
