Fixed Tilt

A fixed tilt array orientation is described with an array tilt angle ($${\theta }_T$$) and an array azimuth angle ($${\theta }_{A,array}$$).

• For example, the orientation of a south-facing, fixed-latitude-tilt array in Albuquerque, NM (latitude = 35.05 degrees N) would have a tilt angle of 35.05 degrees from horizontal and an array azimuth of 180 degrees (using a compass direction convention).
