Power Structures Solar Bracket: With the Power-Structures solar awning bracket, solar panels can be mounted on just about any vertical surface. Put solar on the walls, on deck railings, fences or poles. You’re only limited by your imagination. This is an example of the Curved Brushed Aluminum Bracket Installed. The Awning Bracket is fabricated with a panel angle of 21 degrees off of horizontal. This is considered to be the best compromise of summer and winter production values.
