The rotating shafts 31 and 32 include a first rotating shaft 31 provided at the front end portion on the upper surface side of the housing 1a and a second rotating shaft 32 provided at the upper end portion on the front surface side. The first rotating shaft 31 serves as a rotation center of the first solar energy utilization panel 41 (first heat collecting panel) constituting the upper surface of the housing 1a. The first solar energy utilization panel 41 rotates about the first rotation axis 31 and can be tilted so as to have a predetermined rotation angle θ1 with respect to the horizontal plane. Further, the second rotating shaft 32 serves as a rotation center of the second solar energy utilization panel 42 (second heat collecting panel) forming the front surface of the housing 1a. The second solar energy utilization panel 42 rotates about the second rotation axis 32 and can be tilted so as to have a predetermined rotation angle θ2 with respect to the vertical plane.

In the heat collecting panel, the upper surface side portion enters into the upper surface side portion that rotates toward the housing around the first rotation axis and forms the upper surface side of the housing in the frame. The upper surface of the housing can be configured together with the above, and the upper surface of the housing can be rotated in the direction opposite to the housing around the first rotation axis and exits from the upper surface side portion with respect to the upper surface of the housing. a first heat collection panel Ru tiltable der Te, in front side portions to form the front side of the housing in the frame to rotate towards the housing around the second rotation axis It is possible to enter and configure the front surface of the housing together with the front side portion, and rotate around the second rotation axis in the direction opposite to the housing and exit from the front side portion. a second heat collection panel Ru tiltable der to the front surface of the housing, include,
Solar energy utilization unit, wherein the first heat collection panel Ru to form a substantially rectangular parallelepiped in the housing and the housing upper surface constitutes a by the second heat collection panel constitutes the front surface of the housing ..
