Description

  The present invention relates to a solar cell module mounting structure for fixing a solar cell module to a wall body having an open upper portion such as a fence or a waist wall in a veranda.

  A solar cell is a device that converts solar energy into electrical energy. A photovoltaic power generation system includes an interconnected system that connects to a commercial power source to transfer power, and a stand-alone system that stores the generated power in a battery and uses it for the intended load operation without connecting to a commercial power source. It is divided roughly into.

  When an installation place such as on the roof or on the ground can be secured, when an output comparable to the power consumption of the home is obtained, or for the purpose of commercial power sale, an interconnection system is often adopted. On the other hand, in a housing complex or the like, a stand-alone system is used when a large space cannot be secured for solar cell installation or when the amount of power used is limited to a small amount.

  When a stand-alone system is adopted, a veranda or balcony that can receive sufficient sunlight is a suitable installation location. There is no strict definition for a veranda or balcony, but a roofed one is called a veranda, and one without a roof is often called a balcony. In the present disclosure, both and similar spaces are referred to as verandas. When attaching a solar cell module to a fence that divides a veranda, conventionally, as shown in FIG. 17, an angle is assembled, and this angle is fixed to a vertical lattice 121 of the fence with a metal fitting or the like. A structure has been used in which the free end is fixed by a member extending in the length direction of the oblique side member and the fence headstock 120 to constitute the solar cell mounting base 123 to support the solar cell module.

  However, the solar cell module mounting structure that has been conventionally used is limited to the case where the wall body is easily fixed using a metal fitting such as a fence. When a waist wall of a parapet structure made of reinforced concrete is a solar cell module installation target, a plurality of anchor bolts are driven into the waist wall and the solar battery module mounting base is fixed to the anchor bolt. Installation of the solar cell module mounting base to the fence or parapet structure waist wall and installation of the solar cell module to the mounting base must be done on the outside of the fence or parapet structure waist wall veranda. In addition to being inferior, working on the outside of the veranda is extremely difficult and dangerous on high floors such as apartments.

In order to solve such a problem, a support member having a first fixing contact portion and a second fixing contact portion that are in contact with each other on the inner and outer surfaces of the waist wall and the like is straddled. A solar cell device in which a solar cell is positioned on the outside and an air circulation port is provided in an upper space between the waist wall and the solar cell is known (see, for example, Patent Document 1).
JP-A-002-111033

  However, in the technique disclosed in Patent Document 1, the number of portions where the support member and the waist wall are in contact with each other is small on the inner and outer surfaces of the waist wall. Since it is not used for fixing the module, there is a possibility that the fixing strength of the solar cell module to the fence or the waist wall may be insufficient when force due to strong wind or other factors is applied.

  In addition, since the support member and the solar cell module are integrated with each other and fixed to the fence and the waist wall, it is necessary to lift a heavy object, which results in not only poor workability but also a drop accident of the member. This is especially a problem when working on higher floors. In addition, the angle of the solar cell panel cannot be adjusted, or the support member must be removed from the fence or waist wall together with the solar cell module, and temporarily placed on the inside of these wall bodies, which is problematic in workability. . Further, when performing maintenance of the solar cell such as cleaning, the work is also performed by removing the support material from the fence or the waist wall together with the solar cell module.

  The present invention can be easily installed even if the solar cell module installation target is a fence or a parapet-structured waist wall made of reinforced concrete, etc. The mounting strength is sufficient to ensure safety, and the solar cell module can be safely and easily installed and maintained without dropping any components, and the installation angle of the solar cell panel can be adjusted.
