Meanwhile, a driving means 200 installed inside the main frame 100 to rotate and open the louver panel 110 including the solar panel 130 is included.

By the driving means 200, the angle of the plurality of louver panels 110 can be adjusted so that they all tilt upward at a certain angle from the vertical state.

When described with reference to Figure 6 or Figure 7, the driving means 200 is again installed on the rotation pin 116 of the louver panel 110 and includes a link member 210 on which a pinion gear 212 is formed, and a rack gear ( It may be composed of a vertical bar 220 on which 222 is formed, an elastic member 234 of shape memory alloy to lower the vertical bar 220, and an elastic load housing 230 including the elastic member 234.

The vertical bar 220 may be installed and may include an elastic guide member 236 to guide the expansion and contraction operations of the elastic member 234.

One side of the housing body 232 facing downward is open and a space is provided therein, and an elastic member 234 is supported and installed in the space.

The elastic member 234 is applied as a temperature control spring that guides the movement of the vertical bar 220 by elastic expansion or contraction according to changes in temperature. At this time, the spring for temperature control may be a torsion coil compression spring made of shape memory alloy.

When the elastic member 234 is first assembled, it is assembled in a state that is contracted by a predetermined amount compared to the original length. Then, as the temperature increases, the length of the compressed portion gradually increases and the vertical bar 220 is pushed and moved.

That is, the elastic member 234 made of a shape memory alloy whose overall length changes according to external temperature changes is elastically expanded or contracted, and the position of the vertical bar 220 is adjusted in conjunction with this, so that the vertical bar 220 As the link member 210 of the pinion gear 212 engaged with rotates, the angle of the louver panel 110 can be adjusted.
