My friends! Thanks for interesting in this topic! I am sorry I explained the project without the rest: I want to use solar panels in a sunny, windy and hot place. I live in a island and there is a lot of wind and sun! We use four big Diesel Engines to product electricity. It is mutch more nonsense to use megawatts for frac/Bcoins rather than low voltage, but free, for Monero or Zcash. I automated my OrangePi that it boot after the sun rises! The ARMBIAN should lounches the miner after boot. It boots with 5volts! I would like to mine some Altcoins ASIC resistant. But the only miner seems to be BFCminer. Please could anyone spend few minutes to tell me where I can find a miner for ARM processors? Many thanks and greetings from Italy!
One of strongest arm processors out there, thunderX cavium, does 51 H/s at 10W TDP (so pretty power hungry for ARM processors)
...
(just for comparison, you'll need about 120 of your processors to get same hashing power as single Vega graphic card for mining monero)
Closer to 200 to match a Vega 56 - mine is pulling about 1960 hash with very little work attempted at tuning it (I HATE WATTMAN!), and others have reported higher.
