Final answer:
The tilt angle for a stationary solar array should be approximately equal to the site latitude. It is recommended to tilt the solar panels toward the equator at an angle equal to the latitude of the site.
Step-by-step explanation:
The tilt angle for a stationary solar array should be approximately equal to the site latitude. This means that the angle should match the latitude of the location where the solar array is installed. Tilt angles are optimized to maximize annual yield, and it is recommended to tilt the solar panels toward the equator at an angle equal to the latitude of the site. For example, if the solar array is installed in a location with a latitude of 30 degrees, the tilt angle of the panels should also be 30 degrees.
