Control Method and Device for Quasi-Uniaxial Sun Chase of Solar Panels

Abstract

The present invention relates to a control method and device for quasi-uniaxial sun chase of solar panels. The present method uses uniaxial driving to perform real-time tracking of the zodiacal longitude position of solar “daily periodic change”, then abiding by seasonal “annual periodic change” to perform tracking fine tuning of less 0.25 degrees per day on celestial sphere declination. The present device includes a supporting unit with two corresponding holders on the end face, a frame body for solar panel installation configured between the said two holders, and a control mechanism including a setting unit as well as an enable unit connected to the frame body. Thereby, in addition to real-time correction to the corresponding position of the solar panel to Sun by setting the control mechanism to allow the solar panel to acquire higher incident solar energy. The present invention provides a simple device structure with lower operation power consumption.

1 . A control method for quasi-uniaxial sun chase of solar panels, comprising:
 providing the supporting unit, comprising two corresponding holders on an end face thereof, and a frame body being movably installed between the two holders, a solar panel being installed in the frame body, and a control mechanism having a setting unit and enable units installed therein for adjusting the supporting unit to a preset angle based on a longitude/latitude of a location of the device;   setting default values in the setting unit, allowing the enable unit to rotate the frame body by a first angle per hour to rotate the solar panel; and   pin-jointing the solar panel to a horizontal axle for being movably installed in the frame body, and the control mechanism being connected to the horizontal axle through the other enable unit, further setting default values in the setting unit to rotate the horizontal axle at a second angle per hour to rotate the solar panel.   
     
     
         2 . The control device for quasi-uniaxial sun chase of solar panels according to  claim 1 , wherein the first angle comprises 15 degrees. 
     
     
         3 . The control device for quasi-uniaxial sun chase of solar panels according to  claim 1 , wherein the second angle comprises 0.0107 degrees. 
     
     
         4 . A control device for quasi-uniaxial sun chase of solar panels, comprising:
 a supporting unit, comprising a base and a movable stand movably jointed to the base, wherein two corresponding holders are installed on an end face of the movable stand;   a frame body, comprising two ends respectively movably jointed to the holders;   a solar panel, movably installed in the frame body by being pin-jointed to a horizontal axle; and   a control mechanism, comprising a setting unit and at least one enable unit connected to the setting unit, wherein the enable unit is connected to the frame body, and rotating the frame body at a first angle per hour in order to rotate the solar panel.   
     
     
         5 . The control device for quasi-uniaxial sun chase of solar panels according to  claim 4 , wherein the supporting unit can adjust the base and the movable stand to preset angles based on the longitude/latitude of the location of the device. 
     
     
         6 . The control device for quasi-uniaxial sun chase of solar panels according to  claim 4 , wherein the first angle comprises 15 degrees. 
     
     
         7 . The control device for quasi-uniaxial sun chase of solar panels according to  claim 4 , wherein the solar panel can be pin-jointed to a horizontal axle for being movably installed in the frame body, and the control mechanism is connected to the other enable unit to rotate the horizontal axle at a second angle per hour to rotate the solar panel. 
     
     
         8 . The control device for quasi-uniaxial sun chase of solar panels according to  claim 7 , wherein the first angle comprises 0.0107 degrees. 
     
     
         9 . The control device for quasi-uniaxial sun chase of solar panels according to  claim 4 , wherein the enable units comprise stepping motors or fine-tunable driving motors.
