The azimuth angle of the solar cell array is the angle between the vertical plane of the array and the due south direction (defined as a negative angle to the east and a positive angle to the west). Generally speaking, when the square array is oriented due south (i.e. the angle between the vertical plane of the square array and due south is 0°), the energy production of the solar cells is maximum. . When it deviates 30° from the south (northern hemisphere), the electricity production of the square grid will be reduced by approximately 10% to 15%; when it deviates 60° from the south (northern hemisphere), the electricity production of the square array will decrease by approximately 20 to 30%.
As shown in the figure above, the higher the latitude, the smaller the solar altitude angle. In the figure above, angle 1 is the local solar altitude angle and angle 2 is the angle ? solar panel? Angle 1+ Angle 2 = 90 degrees When angle 1 (the higher the local latitude),in order to ensure that the two are complementary, angle 2 must be increased. , the larger the angle of the solar panel. I hope this will help you.
