<p>A solar self-tracking mechanism for continuously tracking the movement of the sun with time comprises a solar radiant energy receiver secured to a base settled on a ground to be rotatable about a rotating shaftwhich extends horizontally in an east-west direction and plurality of compound parabolic concentrators secured to both longitudinal edges of the solar receiving mechanism in parallel to the rotating shaft. The sun energy concentrated on suitable means such as shape memory alloy coil or solar cell module located at a position coincident with the focal line of the compound parabolic concentrator is transferred to a mechanism for driving the rotating shaft of the solar radiant energy receiver thereby to rotate the same and continuously obtain the solar radiant energy.</p> |
