seriously, selling them separately would attract more people.

i know i am just judging support (if any) we are looking into it its not my bankroll and investor is just starting to believe bitcoin is money

Is it like mining with solar energy. Actually I'm thinking about this concept for some time...

Here is a pic of my warehouse roof.  It is approximately 85 ft X 130 ft.  with some AC units here and there.

Conservatively, how many panels could I fit on it?  I also have Split 240V configuration for power.  What grid-tie inverter would I need?

smracer you are the man! Wow! Bunch of neptune. A lot of mining gear. Going to install solar panel.
That is awesome!

Get a look at Tesalcoin! We are working to bring the crypto community into a green way!

Cheers to solar system!  ;D

Back of the envelope:

10' space all around (fire code for access) = 65 x 90 = 5850sf minus stuff on roof, minus space around stuff on roof (shadows) = 5000sf

15Wpdc per sf = 75kWpdc  (70kWpdc is conservative)

six 10kW inverters (they don't make a 240V 1phase 60kW inverter), or a 250W or 300W microinverter on each PV panel.  Inverter would be sized at about 80% of dc rating of system, due to system losses before inverter output (heat, wiring, inverter inefficiency, soiling)

Limitations:

1. Depending on the version of NEC in effect where you are located (and where the inverter breaker is located in the panel) you can only put 20% or 16% of your service entrance main busbar rating on your main panel, in terms of inverter output amps.  (If your main breaker/fuse is rated smaller than the busbar, then you can put more).

Example, if you have 400A main breaker/busbar, you can only put 64A (pre-2014 NEC) or 80A (2014 NEC) inverter on that panel, meaning 15kW or 19kW inverter.
In that case, you would put only 19kWpdc or 22kWpdc on the roof.  You could only use the 19kW inverter if you had space at the end of the panel busbar for the inverter breaker.

Exception:  You can put up to 320A of inverter on a 400A panel if you do what's called a "line side tap", meaning intertying the inverter between the main disconnect and the meter.  This is not always possible.  It depends on the configuration of your existing equipment, or would require new or extra equipment to achieve.  A 320A inverter would be 77kW, bigger than you would need.

2.  Unless your utility gives you something for production over and above your annual use, you would want to size the system to not exceed in one year what you use.  Example:  If your last 12 electric bills sum to 50,000kWh, you would not want to put a system with more than 50,000kWh annual output on the roof.   Depending on where you live, that is something between 25kWpdc and 35kWpdc of solar.


PS:  A 70kWpdc system would support a 14Th/s "farm" 100%.  Farm takes about 14kW to run, but solar PV has only about a 20% capacity factor, so you need five times as much as your max power draw to supply 100% of annual energy.

PPS:  A 70kWpdc system would cost between 180,000 and 210,000 USD all in, depending on incentives in your area.  More in Hawaii (shipping).

Great business move...do you do shipping deals to Australia?

Will this inverter work?  I have 3 phase split 240V not 1 phase.  I have 1 hot leg of 208V and 2 X 120V legs.  My main breaker box is 1200amp.

http://www.ebay.com/itm/FRONIUS-CL-55-5-DELTA-ISOLATED-CENTRAL-SOLAR-INVERTER-55-5KW-208-240V-3-PHASE-/251278801873?pt=LH_DefaultDomain_0&hash=item3a81623bd1

That inverter looks like it will work, according to the Fronius website data sheet.  175A 3P 240V breaker in the main panel, and a 200A disconnect next to the meter so the utility can shut off the solar system whenever they want. (Check with your utiliity on the disconnect requirement, but that requirement is almost universal in the US).

To be sure, you'd have to check the install manual to see if it prohibits operation on a split phase system.  I can't think of any reason it would be prohibited, but I don't have experience with that service voltage arrangement.

As for the ebay part, you're on your own, of course.  (I did not look at the ebay ad).   Also, if you're getting any kind of incentive, check the fine print to see if all equipment has to be new.

Don't sweat the 65kWpdc limiit on the data sheet.  You can put more on there if you want.  What will happen is the inverter will move it's DC voltage operating point to limit PV input to protect itself.  You'll end up throwing away some kWh over the course of the year when the inverter "clips" like this.  You'd need climate data to estimate how much.  (It will probably do that even on a 65kWpdc system on cold bright days.)

INSTALL DETAIL:  If your city's building department is on a pre-2014 NEC (likely), you may (probably) have to put that 175A breaker at the opposite end of the main panel busbar  from the utiltity feed (or tap the end of the busbar with a fused disconnect, but that's not always possible or UL-compliant).  If you can't make room at the end, you'll have to install a 1000A main breaker to make the install code-compliant (or do the line side tap described in my earlier post). If the busbar is center-fed, you'll have to check with the building department for their requirements on the inverter breaker location and max busbar overcurrent protection so you don't get a bad surprise at inspection time.

This is really interesting, would love to see pictures of any bitcoin related projects you complete.

I heard yu can make solar panels with graphene paint and build your panels and it will be cheaper then buying solar panels. 

What about lifespan

yes cheaper per unit but the output is far less than 305 watts per panel

25 year warranty on our system (manufacturers)

But I wonder how it will help any bitcoin miner.
If anyone thinking profiting from Solar and Mining, you are living years back.
Also, the OP said price is too high. The panel price is $1.3/watt, but it should be near $0.8/Watt.
