A solar tracking device for a solar panel or solar energy collecting device. The solar panel is fixed to a main frame and can rotate wound the frame in the horizontal axis fig 2,5. The frame is supported by a base and can rotate around it in the vertical axis. A control unit takes readings from a sensor attached to the solar panel and uses these readings to calculate the orientation of the panel in relation to the sun. The control unit then moves each axis via electric motors to orientate the solar panel towards the sun. There are two versions of the sensor fig 6,7,8,9. In the 3rd version there is no sensor, instead the control unit elevates and rotates the solar panel in order to locate the position in elevation and rotation of optimal electrical output from the panel, the control unit then orientates the panel for optimum electrical output. |
