Abstract: Methods of solar panel mounting include a method of making a support apparatus for solar panels. The support apparatus is made by attaching an elongated clamp apparatus to an upper portion of a purlin for supporting a row of adjacent solar panels from below. The clamp apparatus is attached to the purlin by extending fastening devices between the purlin and a clamp rail of the clamp apparatus. A portion of the fastening device is captured to prevent it from rotating, and a rotatable member may be connected to the fastening device to cause the clamp apparatus to move firmly against a continuous line of engagement with upper marginal edges of the row of adjacent solar panel supported on the purlin to secure the solar panels between the clamp rail and the purlin.

Abstract: A support apparatus for securing a row of solar panels to a support structure may include a fastener extending between and attaching an elongated clamp rail to a purlin. The fastener has a first non-rotatable end portion. A rotatable member is connected to a second end portion of the fastener for causing, when rotated, the clamp rail to close onto upper marginal edges of the row of solar panels along a continuous line of engagement therewith to help secure the solar panels in place on the purlin.
