A bottom mounted drawer slide is used to provide the linear motion of the board containing the charging components. The slide is attached to a pair of brackets which are mounted directly to the solar rack. Each pair of bracket consist of 2 corner brackets and 3 pieces of aluminum rails. The corner brackets and aluminum rails are joined together with #8 screws. The slider, board, and brackets are joined together with #6 screws. The dimensions of the aluminum rails are the same dimensions of the upper rail of the track.
A similar design utilizing side mounted drawer slides is being worked on.
