I wish I could do that William. Most of the Offgrid places I go would be too expensive/time consuming to even consider driven pipe. The biggest mistake that people make when re-enforcing concrete with steel is not elevating the steel above the ground. This can be a path to rusting out the steel long before its time. We very rarely need Pro engineering offgrid as long as we stay away from roof mounted solar. I always have for offgrid! I save the roof for capturing rain!! Cheers !
