is this completely off-the grid system?

No. We have been mining for 5+ years on the grid at this location. The below picture is a bit deceiving because just to the right is a typical 200amp residential breaker box.

can you not purchase a grid-tie inverter and sell extra power or at least store energy credits with the power company?

The panels being used are SunPower E20 327W AC Modules w/ Integrated Microinverters. They are far superior in efficiency to the typical linked solar panels in a single grid-tie inverter setup. The electric company does allow us to sell excess energy to the grid and I am grandfathered into a plan that allows me to receive retail rates. This is ideal because we will be overproducing in the day to sell at peak rates and buying back power at night when it is cheaper. I am hoping that agreement along with the addition of a wind turbine later this year helps to bridge the gap in the currently estimated 30% shortfall of green energy production needed to sustain the current operation.
