Yes, I'm running my entire mining operation (and actually a lot of other computer hardware) exclusively off solar power. You can purchase a retail solar system for ~$25,000 that will generate around 5000kwh , if you're willing to install it yourself.

You probably mean 5kW.

Not unless he's also including the estimated lifetime of the solar panels in the price. It could be he's expecting the whole thing to only last 1000 hours at 5kW Wink

5000kwhat $0.15/kwh would cost ~$750USD . Why would you pay $25,000 for $750 worth of electricity?

Well apart from the fact that some parts of the world pay more than twice that for electricity, I've drawn a picture of you below:

I thought about that as well, but then realized you'd have to pay $5/kwh to be about the same as this.

He must, cause I am using 24.5 Kw (over 110 amps, most at 220) and my main is warm to the touch Wink

I doubt if a roof full of solar panals could even keep me running.

If he's generating 5000kwh for only $25,000, I'd say I'm in the wrong business!

Very interesting numbers Keefe, Thanks alot !

As I read, it seems more and more clear that the future of mining, in the long run, will mainly be about power cost. I'd like to know if someone has made some research about solar powered mining rig... As the solar is'nt a constant source of power, what are the odds ?

Here the power cost is arround 0.085 CAD/Kwh.. So, if I'll enjoy mining for few years again, at least I hope to !

Thanks again Keefe, and as almost everyone reading this thread, curious to see what the 3 known asic producer will have on the table at delivery

Personally, I bought B grade 5inch panels and built it myself. For under $7500 total. You can get b grade panels for a buck a watt. Since I don't care about being "off the grid", I use grid tied inverters, running my overage back into the gride during the day, and consuming grid power at night. Electric bill... Is less than they pay for postage to mail it to me, and about 12 bucks in taxes.

So let's put some figures together...

Let's a say a professional miner has $100K to invest in mining hardware and is in a good area where power costs only $0.06/kwh.

In the GPU era, with 23 TH network hashrate and 50 BTC block reward, he can buy about 190 GH of GPUs which will use about 63kW of power and earn about $21.5K per month, minus about $2700 for power, for 18.8% monthly ROI.

In the ASIC era, with 280 TH network hashrate and 25 BTC block reward, he can buy about 4600 GH of BFL ASICs which will use about 4.6kW of power and earn about $21.4K per month, minus about $200 for power, for 21.2% monthly ROI.

$200/mo for powering BFL ASICs is quite an improvement over $2700/mo for GPUs.

Now let's imagine a 54 GH bASIC were to use 405W (which I don't believe will be the case):
He can buy about 5100 GH of bASICs which will use about 38kW of power and earn about $23.7K per month, minus about $1600 for power, for 22.1% monthly ROI. Hey, we're ahead of BFL still! But putting that point aside, we would only be twice as power efficient as GPUs

Now let's try a more realistic scenario, where a 54 GH bASIC might use 120W (this is my personal wild guess):
He can buy about 5100 GH of bASICs which will use about 11kW of power and earn about $23.7K per month, minus about $480 for power, for 23.2% monthly ROI. Even better ROI. And now we've cut our power bill to 1/6 of GPUs, very nice.

DISCLAIMER: We really don't know yet how much power the bASICs will use. The wattage figures for bASIC above are purely hypothetical and probably wildly wrong.

I like this analysis

We'll see what the price crash today does to it..

I can't wait to rub it in Inabas face that BFL didn't meet their promised power efficiency ratings along with his rambling about the ROI of said worse efficiency for the users.

At this point I am almost certain they will fail their own specs, if they even deliver Cheesy

This would be even more awesome if their competition would straight out say they were going for FPGA conversion chips and linking to the actual manufacturer with the chips in BFLs devices turning out to be exactly the same thing with sanded off labels.

Bill Clinton is making a lot of sense lately.

If you listen to any of his speeches the main theme is arithmetic.

Just remember...

1+1 will always equal 2 and don't let anyone convince you otherwise no matter how loud they yell.

0x01 + 0x01 = 0x10

you mean 0b01 + 0b01 = 0b10. in hex 0x01 + 0x01 = 0x02..

Complete fail. I almost feel ashamed enough to edit it Embarrassed

No worries man, standard C wont recognize 0b either..

Nice job running the numbers Keefe. This demonstrates the original point of contention that was based on ROI with GPU/FPGA/ASIC 's. Power consumption and power prices will likely play a significant roll in ASIC mining, and even more so as the difficulty rises (not surprisingly).

Anyone have a top 10 links for Inaba's antics on various threads?

Direct links are appreciated! (there are so many to choose from!)

--------------------------------

I got this from BFL:

Hello ******,

I have followed and reviewed the link you sent. Could you please point out where you see defamation and libel, as we are having trouble finding it in the post you linked to, but maybe we are just missing it. Could you also provide a link to post(s) where it was stated (and laughed at) that someone encourages refunds if they are upset at verbal abuse?

Thank you for your time.
