Description

  The present invention relates to a solar cell module support frame that supports a solar cell module for generating power by receiving sunlight.

  Conventionally, when power generation is performed using a solar cell module, the solar cell module is supported on a solar cell module support frame.

  Here, conventionally, the solar cell module support frame is configured to support the solar cell module in a state where the normal of the light receiving surface of the solar cell module forms a certain angle with respect to the vertical direction (for example, (See Patent Document 1).

  This constant angle should be set to around 10 degrees so as to be able to generate power most efficiently during the daytime in summer when power demand is greatest, i.e., to be perpendicular to the sunlight. Many.

  However, since the angle of the sun varies greatly depending on the season, if the angle formed by the normal of the light receiving surface of the solar cell module with respect to the vertical direction is fixed, it becomes impossible to secure a stable power generation throughout the year. Arise. Even if the main purpose is to generate electricity most efficiently during the daytime in summer when power demand is greatest, the vertical direction with respect to the solar rays differs depending on the latitude of the installation location. If it is going to cope with a single solar cell module support stand, even if it is the daytime of summer, the malfunction that power generation efficiency becomes low depending on an installation location arises.

  Further, in an area where there is a lot of snow, if the angle formed by the normal of the light receiving surface of the solar cell module with respect to the vertical direction is reduced, the solar cell module accumulates snow and the power generation amount is greatly reduced. Therefore, the angle formed by the normal of the light-receiving surface of the solar cell module with respect to the vertical direction is increased, but in this case, the power generation efficiency decreases during the period from spring to summer when power demand increases. Another problem occurs.

  The present invention pays attention to the above points, and provides a solar cell module support stand that can secure a stable power generation amount throughout the year, can realize high power generation efficiency regardless of the installation location, and can prevent snow accumulation on the solar cell module. For the purpose.

In order to solve the above problems, the solar cell module support frame according to the present invention has a configuration as described below. That is, one of the solar cell module support pedestals according to the present invention includes a base having a grounding portion and a support column standing from the grounding portion, a panel support material that is supported by the base and supports the solar cell module, A solar cell module support frame comprising a link type angle changing mechanism for changing an angle formed by a support column of the base and the panel support material , wherein the link type angle change mechanism uses the panel support material as a first support. And a second link member provided only for each first link member, a connection point between the base and the panel support member, and the base and the second link member. Are connected to each other, and one end of the second link member is supported by the panel support member .

Further, another one of the solar cell module support frame according to the present invention includes a grounding portion and a base having a support column standing from the grounding portion, a solar cell module supported by the base, and a support column of the base. And a link type angle changing mechanism for changing an angle formed by the solar cell module, wherein the link type angle changing mechanism uses the solar cell module as a first link member. And a second link member provided only for one first link member, and a connection location between the base and the solar cell module, and a connection location between the base and the second link member. In addition to being constant, one end of the second link member is supported by the solar cell module .

  If it is such, the angle which the normal of the light-receiving surface of a solar cell module makes with respect to a perpendicular direction is changed by changing the angle which the support | pillar of the said base and a panel support material or a solar cell module make. It can be changed according to the installation location. In other words, the angle that the normal of the light-receiving surface of the solar cell module makes with the sunlight is reduced throughout the year, regardless of the season, to ensure stable power generation throughout the year, and to respond to the sun angle at each installation location. Thus, by reducing the angle between the normal line of the light receiving surface of the solar cell module and the sunlight, high power generation efficiency can be realized regardless of the installation location. In addition, it is possible to prevent snow accumulation on the solar cell module by increasing the angle formed by the normal of the light receiving surface of the solar cell module with respect to the vertical direction in winter when there is a lot of snow in winter.

  As a configuration for realizing such a solar cell module support frame with a simple configuration with few movable parts, the link type angle changing mechanism manually changes the angle formed by the base column and the solar cell module. Is mentioned.

  As an example of the configuration of the solar cell module support frame described in the previous stage, which enables quick and easy angle adjustment, the link type angle changing mechanism includes the panel support material or solar cell module as a first link member, and the panel. Supports either a second link member having one end supported by a support material or a solar cell module, and a supported portion provided on the support column of the base and provided intermittently on the second link member. And a link member support part.

  Further, as another example of the configuration of the solar cell module support frame capable of adjusting the angle quickly and easily, the link type angle changing mechanism includes the panel support material or the solar cell module as a first link member, and the panel support. A material or a solar cell module is supported on one end and a base is supported on the other end, and includes a second link member that can expand and contract. In particular, if the second link members of the plurality of solar cell module support frames are connected, the second link members of the plurality of solar cell module support frames can be expanded and contracted by a single operation, and the angle can be changed. The labor required for this can be reduced, which in turn can save labor costs.

  When the grounding part of the base is a rectangular plate, it is difficult to place the bases in an overlapped state, and securing the space during temporary placement or transportation becomes a problem, but the grounding part of the base is If the base of another solar cell module support base having the same structure has a cutout portion on which the base can be placed, another base having the same structure can be placed in the cutout portion. Multiple bases can be placed in the same space during transportation.

  In the present invention, the “support column” is a concept that indicates the whole of the solar cell module support frame that stands up from the grounding portion, and includes not only a bar-shaped one but also a planar one.

  ADVANTAGE OF THE INVENTION According to this invention, the solar cell module support stand which can ensure the stable electric power generation amount through the year, can implement | achieve high electric power generation efficiency irrespective of an installation location, and can prevent the snow cover to a solar cell module can be provided.
