The material for absorbing hydrogen used for the metal hydride actuator is LaNi ₅ Ni _4.5 Al
_0.5 and Ca-Ni-Mm-Al are known, and a desired equilibrium hydrogen pressure can be obtained from the composition of these metal elements and the like. The equilibrium hydrogen pressure P and the absolute temperature of the metal hydride The relationship with T is expressed by the following Van't Hoff equation.

[0028]

(Equation 1)

This relational expression indicates that when the temperature T of the metal hydride increases, the hydrogen pressure P increases, and when the temperature T of the metal hydride decreases, the hydrogen pressure decreases. The heat generated by irradiating the heat receiving plate with sunlight can increase the hydrogen pressure and take out the pressure increase as power.

In the above configuration, since the operation of the solar tracking device can be achieved only by heat using sunlight as a heat source, no operating power is required and the efficiency of the entire solar power generation system can be increased.
