Heliostat apparatus and solar power generating method

A heliostat apparatus including at least one reflection mirror reflecting sunlight or solar battery panel, in which an angle of a reflection surface of the reflection mirror or a panel surface of the solar battery panel is adjusted while causing it to follow movement of the sun, comprising:

• a frame supporting the reflection mirror or the solar battery panel;
• a gyro mechanism having an elevation angle rotation axis for rotating the frame in a north-south direction with an east-west direction as an axial direction and an azimuth angle rotation axis for rotating the frame in the east-west direction with the north-south direction as an axial direction, the elevation angle rotation axis and the azimuth angle rotation axis being orthogonal to each other;
• and
• a support for supporting the frame through the gyro mechanism, wherein
• by integrally rotating the frame and the reflection mirror or the solar battery panel in the north-south direction with the elevation angle rotation axis as a rotation axis, the angle in the north-south direction of the reflection surface of the reflection mirror or the panel surface of the solar battery panel supported by the frame is adjusted;
• by integrally rotating the frame and the reflection mirror or the solar battery panel in the east-west direction with the azimuth angle rotation axis as a rotation axis, the angle in the east-west direction of the reflection surface of the reflection mirror or the panel surface of the solar battery panel supported by the frame is adjusted;
• and
• the center of gravity of a power generation panel including the frame and the reflection mirror or the solar battery panel supported by the frame is matched with an intersection where the elevation angle rotation axis and the azimuth angle rotation axis of the gyro mechanism are orthogonal to each other.

A solar power generating method for generating solar power by disposing plural heliostat apparatuses including at least one solar battery panel on the ground while an angle of a panel surface of the solar battery panel of each of the heliostat apparatuses is adjusted by causing it to follow movement of the sun, wherein

• the plural heliostat apparatuses are of a gyro type, and if the panel surface of the solar battery panel of each heliostat apparatus directed perpendicularly to sunlight,
• in a time slot when shade is not generated on the panel surface of the solar battery panel of another heliostat apparatus by the panel surface of the solar battery panel of each heliostat apparatus,
• the angle of the panel surface of the solar battery panel of each heliostat apparatus is adjusted perpendicularly to the sunlight, and
• in a time slot when shade is generated on the panel surface of the solar battery panel of another heliostat apparatus by the panel surface of the solar battery panel of each heliostat apparatus,
• the shade of the panel surface of the solar battery panel of each heliostat apparatus is made to shift from the panel surface of the solar battery panel of another heliostat apparatus and is generated on the ground, and on the basis of a size of an area of the shade generated on the ground, the angle of the panel surface of the solar battery panel of each heliostat apparatus is adjusted;
• and
• solar power generation is performed.
