In an aspect, the present disclosure describes a system for constructing a solar module array. The system can comprise one or more mobile platforms; one or more carriers operatively coupled to the one or more mobile platforms, wherein the one or more carriers support a plurality of posts and/or a plurality of solar modules; one or more robotic components for retrieving one or more posts from the plurality of posts and one or more solar modules from the plurality of solar modules from the one or more carriers; and at least one controller in operative communication with the one or more mobile platforms and the one or more robotic components, wherein the at least one controller (i) directs the one or more mobile platforms to transport the one or more carriers over a terrain and (ii) controls the one or more robotic components to (1) autonomously position and install the one or more posts on the terrain, and (2) autonomously position and assemble the one or more solar module to the one or more posts installed on the terrain to thereby construct the solar module array on the terrain.
