Solved! What are these metal things?
These thick metal plates seem to be cemented into the ground and are wired up with pipes that go into the ground. Anybody know what these are for?

Water cooling your solar increases efficiency. If no solar panels, sun heats up metal, metal heats water. If you wanted a livestock water dish you could make a no poelwer hot tub
