The curvature resists backfill loading on the panel and evenly distributes the load across the panel without significant stress concentrations and transfers the load to posts or columns to which the panels are mounted. A wall panel having a post attachment flange on one side for attachment to one post, and a post surround channel on the other side for at least partially surrounding another post. The system may optionally include one or more composite polymeric posts for supporting the panels.
