The panel attachment system includes opposite upper and lower tracks attached to the edges of an opening in a building structure, and one or more panels that secure removably to the tracks to protect the opening from extreme weather, such as hurricane force winds. The upper track has a generally "h" shaped cross section and secures the upper edge of the panel therein. The lower track has a generally "F" shaped cross section, and holds the heads of a series of threaded fasteners in the channel of the track. The threaded shanks of the fasteners protrude outwardly normal to the building structure, pass through holes formed in the lower edge of the panel, and are secured by corresponding nuts. Two or more panels may be joined to cover a wider opening. The panels may be formed of corrugated plastic material.
