Racking assemblies for solar panel installations are provided. The racking assemblies may include a series of posts arranged in two parallel rows and anchored to the ground or other suitable surface. Purlins may be coupled to and may span the posts of each row. Specialized clamps may be used to attach the purlins to a series of mounting rails. The mounting rails, in turn, may support an array of solar modules.
