Several pre-assemblies holding panels of photovoltaic cells are constructed and pre-wired in a factory. The pre-assemblies are shipped to a solar farm, where they are lifted above posts secured to the ground. By being foldable, the solar panel assemblies can provide a compact shipping arrangement. Operators can connect the solar panel assemblies to a support and then unfolded the solar panel assemblies and lock them in the unfolded position.

Various connection devices and assemblies, such as telescoping riser joints, can include at least one of the present connection devices. Some of the present connection devices, for example, include a housing having a bore therethrough; a locking ring rotatably movable relative to the housing between a first position and a second position; and an engagement member laterally moveable relative to the bore of the housing between a retracted position and an extended position. In some such connection devices, the locking ring is configured such that movement from the first position to the second position causes the engagement member to move from the retracted position to the extended position.
