However, regardless of your result, you still need to include the additional cost of your off-grid solar system to ROI since the end goal is to build an off-grid farm.
Or is everything already paid just like the additional 40kW panels you have now?
Yes, mostly paid other than more inverters and mounts for the panels.
Okay, I guess the 'Total Off-grid' plan is already laid out regardless of the result of this 50kW solar power experiment.
How about taking a chance in the $160k bitcoin lottery and solo mine it?
Time estimate: 10 years
0.00000194% chance per block isn't too bad.
Time estimate isn't really a good basis since this "
10 years" could be the block in the next 10 minutes or the next 10 years.
An extreme example is the miner of block 853742 who only had 3.1TH, reference:
/index.php?topic=5237323.msg64356985#msg64356985But don't take that as an encouragement to solo, just saying that a very low chance has a chance.
Annual ROI: Negative until after the payback period (~3.89 years)
At last, someone who doesn't think that "
ROI" is the same as "
Capital Return". ;D
Also, take the gradual increase of total network hash rate in consideration and the next "
halving" if it would take more than 4 years from now to ROI.
