Method for determining optimum tracking angles of photovoltaic tracking systems under standard equatorial coordinate system

The invention provides a method suitable for determining optimum tracking angles of photovoltaic tracking systems of various structures. The method solves the optimum tracking angles of single or double axis photovoltaic tracking systems of inclination axes in a vector method. By means of the method, the optimum tracking angles of gradients of the installation ground or gradients caused by installation errors of the single or double axis photovoltaic tracking systems can be rectified, and the optimum tracking angles of inclination toward the due south of installation direction of the single or double axis photovoltaic tracking system caused by limitation of the surrounding environment or installation errors can be rectified. The method has the advantages of being capable of automatically rectifying tracking errors caused by ground gradient, system direction, construction inaccuracy and the like and enabling the tracking system to be high in efficiency and stability and low in cost.
