Abstract: The present invention relates to a solar power generation apparatus, which comprises: torque tubes which are arranged to form a plurality of columns; a plurality of solar panels which are installed along each torque tube; posts which rotatably support each torque tube; lever arms which are coupled with each torque tube; a linkage which is disposed on the lower side of the torque tubes and is connected to each lever arm; an actuator which reciprocates the linkage in the longitudinal direction of the linkage, thereby rotating the torque tubes around an axis based on the longitudinal direction of the torque tubes; and a bed frame which is installed between some of the plurality of posts, wherein the actuator is supported thereon.

Abstract: A synthetic resin bearing for a photovoltaic tracking system includes first and second bearing members coupled with each other for forming a bearing assembly. Each of the first and second bearing members has a pair of side plate members facing each other. A friction member is positioned between outer peripheral portions of the pair of side plates has an arc-shaped section. A reinforcement member connects the pair of side plates and the friction member, and the first and second bearing members have a coupling protrusion and a concave portion for receiving the coupling protrusion.
