US Patent 11228275 Methods and apparatus for installing solar panels

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 using, for example, using an excavator connected to an end effector. The pre-assemblies are then connected to the posts and electrically coupled to one another. Such installation of solar panels in a solar farm may be faster and less labor-intensive than other types of installation.
