300W x 45GPU give 13.5KW of instant power consumption,

but with a battery of 13.5KWh of capacity you can only provide 13.5KW of electricity during 1 hour.

so you have to mutiply by 24 the number of battery to mine all the day (24h/day)
Solar panel or the grid have to feed all your battery with 13.5KWH*24 = 324KWH per day
( i don't take in consideration that you will not keep 13.5Kwh very long if you draw 100% of battery capacity everyday)

if you go solar only, you have to produce 324Kwh during 8-10 hours a day
let says 8 hours of solar production per day (because you don't get 100% of panel production during the 8 hours of the day)
that give 324KWh/8h = 40 Kw of instant production, so arround 135 solar panel of 300W

in real world you will need more panel, arround 200 to get the 40Kw average of instant production and hope to match the 324 Kwh of daily production on sunny days

a quick calculation is between 3.5 to 4 solar Panel of 300W per GPU that consume 300W

Hello guys,
I was navigating through the web and I found this information about RTX 2080ti GPU.

Quote
Power Consumption

The GeForce RTX 2080 Ti registers ~277W through our stress test and almost 279W in our gaming loop (nearly 20W higher than Nvidia's official TDP rating).



Reference: https://www.tomshardware.com/reviews/nvidia-geforce-rtx-2080-ti-founders-edition,5805-10.html

Well, the question is what is the exact power consumption for mining?
I guess based on this information, a 2080ti gpu is consuming ~279 watts (for gaming) ok, let's say ~ 300 watts for mining
Therefore, a single 13.5 kWh Tesla PowerWall 2 will power approximately 45 GPUs. Guys, correct me if i'm wrong, i'm no expert on this... thanks Smiley  

6 Tesla PowerWall 2s will roughly power 270 RTX 2080ti GPUs... 12 Tesla PowerWall 2s will roughly power 540 RTX 2080ti GPUs. But only if i'm right!

It really amazes me how little people understand about solar. In almost every case, solar is a supplemental energy source, as you can only generate useful power for maybe 10h a day if you are in a sunny desert.

Good luck with this fools errand!

Uh, 150 solar panels @ say 300w each will generate 45,000 Watts at noon on a sunny day during the summer.  So during that brief moment each day (in the summer months only), you can power 225 GPUs that consume 200 Watts each.

So unless you farm is floating in space with sun 24/7, you will only see a fraction of that power on an annual basis.

I currently have 128 panels with a total output of about 34,000 Watts at noon on a sunny day during the summer.  Last month I generated a total of 2,151 kWh from this array.  There were 28 days in February, so that works out to an average production of 77 kWh per day, or 3,200 Watts per hour.  That in turn translates into 16 GPUs @ 200 Watts.

During March, I have had a few days where I generated 175 kWh, which translates to around 7,300 Watts on a 24 hour average, or enough to power 36 200W GPUs.

Not sure why you want to go off grid.  It is MUCH more economical to be grid tied, especially if your POCO offers net metering.

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 Kiss

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 Grin

Take a look at my Green Energy Project: https://bitcointalksearch.org/topic/112kw-solarwindman-nastymining-green-energy-project-1783328

I'm doing something similar with a Powerwall 2 and some solar/wind/man energy.  I must say though, without the grid it would be very difficult to keep these powered a majority of the time.  The Powerwall 2 has 13.5 kWh of power storage.  Lets say you get 10 hours a day of sunlight, which leaves 14 hours of the day needing to be powered by the Powerwall 2.  A single 2080 ti would use around 5 kWh during that period.  This means you would likely only be able to power 2-3 2080 ti gpus per Powerwall 2.  For 50 of them, you'd be looking at >17 Powerwalls 2s to keep them running off the grid.  You'd also need to produce >400 kWh of solar electricity per day.  A solar system that size would likely cost you more than $200,000, with another $120,000 for the Powerwall 2s and another $65,000 for the GPUs.  

It can definitely be done, but you're looking at spending over $400,000 before you figure in the costs of cooling and space to fit all those solar panels and Powerwalls.  Seems like a lot of effort and risk for $45/day in income.  

For power, I found: https://www.tesvolt.com/en/tps.html

1. Tesvolt Lithium Battery Storage 500 kWh TLC 500
2. Tesvolt Lithium Battery Storage 1MWh TLC 1000

PowerWalls can't deliver enough energy to my farm.

Yeah, many of us here want to start crypto mining but the major problem we have is the power
And we all know about the Tesla Powerwall 2 which is one of the best lithium-ion batteries out there.
My mining farm is going to be fully solar powered using Tesla batteries. any advice is welcome.

I want to build something like this...





look up the industrial tesla batteries , the powerwall will barely power one ring , you need industrial storage

Welcome to the other side brother, explore Jehu's youtube and educate yourself.

"Tesla Batteries" could pertain to a variety of differently spec Lithium Ion cells, most likely your referencing the 18650
