Should the hardware be custom made? Should electricity be produced on site? What is there to know about such procedures?
sure!
i'm planning to build a solar farm.
with the latest tesla powerwall 2, we can build a battery array.
Powerwall 2 has 13.5 kwatt storage!!!!!!
this is damn good!!!!
and won't keep a single S9 powered up through a winter, early spring, or late fall night, even if you can manage 100% conversion efficiency from that storage to the AC line to power an S9.
Solar is a generally BAD idea for a miner, the up-front costs amortise out to a rather HIGH rate per KWH actually generated - it's OK if you already HAVE the solar stuff in place, but buying solar with the idea of just using it to mine on will NOT pay off.
