Abstract

An adjusting device for adjusting orientation of an energy conversion board comprises a first frame member, a second frame member, a third frame member and a base. The first frame member contains the energy conversion board. The second frame member holds the first frame member. The third frame member holds the second frame member. The base supports the third frame including the other frames and the energy conversion board. The first frame member is rotatable relative to the second frame member, the second frame member is rotatable relative to the third frame, and the third frame member is rotatable relative to the base. The first rotating axis is perpendicular to the second rotating axis, and the third rotating axis is coaxial with the first rotating axis.
