Description

Solar cell module, mounting structure thereof, and tile material used for the same

Technical field

The present invention relates to a solar cell module, a mounting structure thereof, and a tile material used for the same, and more particularly, to a solar cell module mounted on an inclined roof, a mounting structure thereof, and used for mounting such a solar cell module. It relates to tile materials.

Background art

[0002] In recent years, solar power generation systems have been receiving attention as environmentally friendly power systems.

The photovoltaic power generation system can meet the power demand of ordinary households by installing a solar cell module on the roof of a general house, and is generated by solar power from the power consumed by each household during the day. If power surpasses, it is possible that surplus power can be sold to electric power companies. In this respect, it is expected that the spread to general households will further increase in the future.

[0003] At present, when introducing a photovoltaic power generation system, not only the performance of the photovoltaic power generation, but also the cost aspects and the maintenance of stable operation due to the ease of installation on the roof and the ease of maintenance, etc. Motivation is very important. In a solar power generation system, dozens of solar cell modules (panels) are installed on the roof according to the amount of power required for the home. It is also a social requirement that safety be ensured, that the solar cell module be prevented from falling off the slope roof after construction, and that the safety of maintenance work be ensured. It is also a deciding factor for the power of introducing a solar power generation system.

[0004] Japanese Utility Model Laid-Open Publication No. 6-44879 (Patent Document 1) proposes a method for simplifying installation of such a solar cell module on a roof and ensuring safety. According to Patent Document 1, it is necessary to first attach a detachable fixing device for a solar cell module. Prepare the required number of solar cell units consisting of multiple solar cell modules assembled by force. The prepared solar cell unit is hung on a sloped roof and installed on the roof with wires. After that, a solar power generation system is constructed by connecting the power terminal cables of each solar cell unit.

[0005] However, this method requires an additional operation in addition to the operation of fixing the solar cell unit. In other words, in order to connect the power terminal cable, remove the fixings of the solar cell module on the sloping roof, slide the solar cell module, and then turn over the solar cell module, for example, about 985 mm x 445 mm. Unstable and complicated work is required.

[0006] In addition, when a solar cell module is damaged due to bad weather such as a typhoon, or when a solar cell module having deteriorated performance is replaced, such a defective solar cell module is located in the center of the solar cell unit. If it is located nearby, there is a restriction that a defective solar cell module cannot be removed without removing some normal solar cell modules.

[0007] Therefore, in order to replace a defective solar cell module, the number of solar cell modules temporarily removed from the roof increases on the roof, and there is a great possibility that the solar cell module will lose its roof power. In some cases, the situation was such that safety could be impaired during work.

[0008] Also, if the solar cell module is to be fixed to the roof with wires, and if the same degree of fixing to the roof as the tile material is to be obtained, the number of wires needs to be increased. Occasionally, the number of man-hours for fixing to

In order to solve such a problem, Japanese Patent Application Laid-Open No. H11-107453 (Patent Document 2) proposes a solar cell module in which a solar cell unit has the same size as a tile material.
