Description

  The present invention relates to a photovoltaic power generation system.

The basic principle of solar cells is not to place an object that obstructs light reception upward. On the other hand, in order to secure a large amount of power generation by the solar cell, it is necessary to secure a wide installation area.
For this reason, in densely populated areas such as urban areas, it has been necessary to devise the installation location and installation method in order to secure the solar cell installation area.

For example, in Patent Document 1, a photovoltaic power generation system is constructed using the area in the track of a railway track.
This solar power generation system secures a solar cell installation area by disposing a solar cell module on a sleeper inside the rail of a railroad track.

JP 2004-311502 A

Since the conventional solar power generation system fixes the solar cell module to the sleepers, the conventional solar power generation system is disposed at a position lower than the rail. For this reason, the solar cell module cannot be disposed in the shaded portion of the rail, and the installation area is limited.
Moreover, since the solar cell module is fixed to the sleepers, the solar cell module cannot be installed on the outer portion of the rail.

Pressing means, and the solar cell module is pushed down by the pressing means when the vehicle travels on the traveling rail by the wheels.

  Such a solar power generation system always efficiently generates power by the solar cell module disposed adjacent to the traveling rail, and the solar cell module does not fall and prevent the vehicle from passing when the vehicle passes. It is possible to install adjacent to the rail without being limited to the inside and outside of the rail.

  Further, a second photovoltaic power generation system according to the present invention includes a traveling rail, a vehicle traveling on the traveling rail, a solar cell module disposed above the traveling rail, and a side of the traveling rail. The solar cell module is supported by the support member so as to be laterally movable, and the vehicle presses the solar cell module laterally. When the vehicle travels on the travel rail, the solar cell module is laterally moved by the pressing means.

Since such a photovoltaic power generation system covers the rails with solar cell modules,
The entire rail track can be effectively used as the installation area of the solar cell module.
Further, since the solar cell module moves laterally when the vehicle passes, it does not hinder the vehicle from traveling.

  According to the photovoltaic power generation system of the present invention, it is possible to ensure the installation area of the solar cell module by effectively utilizing the trajectory.
