How to calculate Solar array row spacing

There are many factors effecting the output of a solar plant.Here we would like to share some ideas for questions below:

Do shadows affect solar panels?

Definitely yes!

The height Angle of the sun varies with local time and the declination of the sun. Design optimal solar array spacing to prevent solar panels from being shaded so as to maximize the power output of the solar panels of the solar PV plant.

How do you calculate row spacing?

The sun declination is symbolized by δ(equal to the latitude of the point of direct sunlight)

Latitude of the observed earth symbolized byφ(Both declination and latitude are positive in the north and negative in the south) Then H = 90°-|φ-δ|

The height Angle reaches its maximum at noon, the height Angle reaches its maximum at 90 degrees.To find the height Angle of a place, you need to know the latitude of the direct point (i.e., the declination of the sun), and to know the latitude of the measured place, you can calculate the height Angle of the place at noon, and the height Angle of each time.

Once the height Angle is known, it is easy to calculate the array spacing, as shown in the following figure.

As figure below:
