Description

  The present invention relates to a solar panel base for fixing a solar panel in a construction area, a solar power generation apparatus using the base, and a solar power generation apparatus construction method.

  In recent years, many photovoltaic power generation devices have been installed on vacant land, rooftops, and the like due to demand for electric power. Conventionally, when installing a solar panel on the ground, a concrete foundation is placed on the ground, a base made of a metal frame or the like is built on this foundation, and a solar panel is installed on the base. It was. Such a solar panel installation method can build a base that can securely fix the solar panel, while digging the ground in the construction area to build concrete from the foundation, or formwork to form the foundation Therefore, there are problems that the number of man-hours required for construction increases and the manufacturing cost increases.

  In order to solve this problem, a solar panel mount described in Patent Documents 1 and 2 is known. This gantry is characterized in that a solar power generation device can be easily installed by placing it on the ground or rooftop, which is a construction area of the solar panel, and attaching the solar panel to the upper part.

The base part that supports the conventional solar panel has cooled the solar panel with air by blowing air between the frames, and suppressed the temperature increase of the solar panel due to the irradiation of sunlight. However, since the mounts of Patent Documents 1 and 2 block the wind passing through the back surface of the solar panel by the wall surface of the mount, the cooling efficiency of the solar panel may be reduced. When the cooling efficiency of the solar panel decreases, the power generation efficiency decreases due to overheating of the solar panel.
