合金材料を用いることが望ましい。It should be noted that the shape memory spring 40 changes only in one direction, ie, expands when heated, to become the memory form 40a, and does not change in the opposite direction by cooling. Therefore, after the sun sets to the west in the evening, if the sun rises from the east the next morning, the solar cell module 12 cannot receive power from the heat of the sunlight at night, If it is out of the range, it may not be possible to track the sunlight as it is. To handle such cases,
A heating unit for correcting the position of the solar cell module 12 by heating the desired shape memory spring 40 to a temperature equal to or higher than the reverse transformation start temperature at regular time intervals may be provided. Further, the position of the solar cell module 12 may be corrected using a motor. In summer, the ambient temperature in the vicinity of the shape memory spring 40 may be higher than the transformation start temperature of the shape memory spring 40 due to an increase in temperature due to direct sunlight. Therefore, as the shape memory alloy material of the shape memory spring 40, the transformation start temperature is determined by the shape memory spring 40.
It is desirable to use a shape memory alloy material set sufficiently higher than the ambient temperature in the vicinity of.

が太陽光発電装置３０上で安定する。The principle of operation will be described with reference to FIGS. When the sunlight 11 is obliquely incident as shown in FIG. 11, the position of the focal point 71 by the condenser lens 10 moves to the heat receiving component of the heat receiving plate 70 as shown in FIG. 12, and heats the heat receiving component of the heat receiving plate 70. . When heat is transmitted from the heat receiving component of the heat receiving plate 70 to the shape memory plate 41, the shape memory plate 41 is heated and deformed in the direction in which the heat receiving plate 70 is pulled up so as to be in the storage mode 41a as shown in FIG. Since the solar cell module 12 is connected to the pedestal 72 by the universal joint 50, the other two shape memory plates 41 maintain the bending deformation 41b, and the solar cell module 12 moves in the direction of the sun. This movement is repeated, and the focus 71 as shown in FIG.

用いることが望ましい。It should be noted that the shape memory plate 41 undergoes only a one-way change such that it expands to a storage form 41a when heated, and does not undergo a reverse change by cooling. Therefore, after the sun sets to the west in the evening, if the sun rises from the east the next morning, the solar cell module 12 cannot receive power from the heat of the sunlight at night, If it is out of the range, it may not be possible to track the sunlight as it is. To handle such cases,
A heating means for correcting the position of the solar cell module 12 by heating the desired shape memory plate 41 to a temperature equal to or higher than the reverse transformation start temperature at regular time intervals may be provided. Further, the position of the solar cell module 12 may be corrected using a motor. In summer, the ambient temperature in the vicinity of the shape memory plate 41 may be higher than the transformation start temperature of the shape memory plate 41 due to an increase in temperature due to direct sunlight. Therefore, as the shape memory alloy material of the shape memory plate 41, it is desirable to use a shape memory alloy material whose transformation start temperature is set sufficiently higher than the ambient temperature near the shape memory plate 41.
