Sections in the corner of the 300 level are located on both sides of the field. Among these sections, Sections 322-326 provide the best overall experience. They do not get the sun directly and have a decent angle towards the lone videoboard.
If you're looking to competely avoid the sun, choose sections 336 and 337 on the Southwest side. The sun will set behind these sections instead of directly in your face. The one downside is that you won't be able to see the videoboard without turning your head.
Each of these corner sections contains 25 rows of seating.
