I've run these numbers before. 'OgNasty' is correct. You would need AT LEAST $500,000 in solar alone (not including batteries) for your 50x 1080ti setup to be 100% run on solar. Could even run you higher (~$1million). Good luck. ROI > 30 years.
No... You've got it all wrong. For power, I have to invest only $175,000 for 2 MWh batteries + 150 solar panels (off-the-grid) which would power up to 400 RTX 2080Ti GPUs. And the cost for 400 2080Ti GPUs is somewhere around $520,000. For land, this is going to cost me around $30,000 + miscellaneous ~ $20,000. The grand total of the initial investment is going to be $745,000, not a million. In the beginning, the return is going to look small $400-$500/day - After a year, once we got another market boom similar to 2017 - I don't need 30 years to get the ROI, I'll see it in a matter of months, or a year or so max
Let's do the math, at the market boom the average crypto gets 10x in value.
So, let's take $400/day x 365 days = $146,000
Average crypto gets 10x in value during a market boom.
Therefore, $146,000 x 10 = $1,460,000 for the year in the bull market.
You see I told you I'll get my ROI in a year or so... The only thing to wait for is the next market boom
