Ground screws, most commonly used in ground mount solar installations, although the old fashioned concrete sonotube seems to refuse to die. For the most part seems as if all of these ground screw systems are more or less the same, large drill of some sort drives screw in to ground, maybe four or five feet and then racking system is attached, easy. These are also used for more typical construction projects, pergolas, decks and even foundations for sheds or garages. Not sure if I would use them on a whole house though, still like the idea of having a basement. Below we’ve started to compile a list of different manufacturers and possibly installers for our own record.
Just a few, more to come when and if we find them.
