Component Spacing Calculation

The overall layout plan of the power station is designed and arranged based on the dimensions of the solar panel arrays and the corresponding number of arrays.

The land area occupied by the solar panel arrays and their arrangement are closely related to the latitude of the power station's geographical location. According to experience, the spacing between solar panels must meet the following condition: if, on the winter solstice—the day with the lowest solar altitude angle—the shadows of the solar panels do not interfere with each other between 9:00 AM and 3:00 PM local time, then the output of the panel arrays will not be affected.

The schematic diagram of the front and rear spacing for fixed solar panel arrays is shown below:

The tilt angle of the solar panels relative to the horizontal plane is 15 degrees.

Solar panel array front and rear row spacing is generally determined by the principle that the solar panel array should not be shaded between 9:00 AM and 3:00 PM on the winter solstice. The spacing between arrays or the vertical distance from any potential obstructions to the bottom edge of the array should be no less than D.

The calculation formula is as follows:

Where: φ is the latitude (positive in the Northern Hemisphere, negative in the Southern Hemisphere). The latitude of this project is φ = 31.23° North.

The installation tilt angle of the panels is a = 12°.

Double-row horizontal arrangement:

Solar panel dimensions are 1650 × 992 mm.

According to the electrical layout, the horizontal length of two component panels is L = 1.96 m (including the frame).

H is the projected height of the fixed panel after installation, calculated as:

H = L × sin(a) = 1.642 × sin(15°) = 0.417 m

Substituting the above values into the formula: D = 0.79 m
