Do you know anyone who mines on solar with direct DC?

I too am interested in this.
@rev.hodl are you using direct dc?
I've done experiments and proof of concepts but nothing consistent.
S9 hashing on direct DC solar and AC PSU hybrid system
Here I have an S9 powdered both by the 12v DC output of a solar charge mppt controller and the output of an apw3++ plugged into an inverter. The output of the solar charge controller is wired directly to DC output lugs of the PSU. As the clouds roll by the output of the solar power decreases and the PSU delivers more power from the inverter. This same technique can be used by plugging the PSU into a grid powered outlet instead of the inverter. It's basically a way to subsidize the power consumption of a miner with solar power directly. It's pretty cool to watch.

We have looked into this a little bit. Hashboards are 12vDC which is easy enough to produce, however is susceptible to voltage drop without very large cable. As such, most PV modules run at a higher voltage. You would need to use charge controllers that step power down from a higher voltage coming off of the PV array to 12v for a battery bank. You then need the miners to be very close to the batteries to save on copper. My assessment is that it’s doable for small scale hobby projects but not economically practical for anything you’re trying to really stack with. 48v batteries with inverters provides a more reliable solution for any kind of scale IMO
