I paid $.65/watt including shipping (bought from a wholesaler on eBay), $2800 for 2 inverters, installation was $1.10/watt (1 inverter would have worked if I went with SolarEdge w/optimizers). I had to take a break from mining when my Edison bill hit $900 last November for running about 8 TH.

I'm guessing you did the ROI math for the solar factoring in other uses at your home, because otherwise I fail to see how spending thousands of dollars in solar equipment is a good "investment".  Don't get me wrong, I think it's really cool, but the finances rarely make sense to me.

I really didn't do the ROI math, I was thinking at least I could sell excess production at $.09/kW if mining didn't work. At current hardware price and ever increasing difficulty, it is kind of impossible to ROI even with free electricity, but everybody still wants to mine, right!

I have been adding panels and inverters to my solar setup for years now. It's a pretty low budget setup. That's why I have many smaller grid tie inverters versus one larger one. Usually I buy a few panels at a time and wire them up.

Everything was purchased with the ROI from a couple dozen ztex and other fpga boards that I ran years ago, including current mining gear.

The pictures of my power sipping fpga and early asic setups are somewhere in this thread Wink

I will chime in since I just installed a 7.65 kW system mostly to offset my electric bill from mining, however, it is completely a grid-tie system. I paid $.65/watt including shipping (bought from a wholesaler on eBay), $2800 for 2 inverters, installation was $1.10/watt (1 inverter would have worked if I went with SolarEdge w/optimizers). I had to take a break from mining when my Edison bill hit $900 last November for running about 8 TH. Not entirely sure if this system will help in ROI for running S7s, on the other hand, Edison buys back extra power @ $0.9/kW $0.09/kW..

so you spent around $15,000 for 7.65kW and no battery packs?

IIUC, that means you should get ~7kw*12h = 84kwh/day (~$8), and it will take roughly 2000 days, or 6-7yrs, to pay back the system cost assuming no surprises

as i understand, thats not too bad since solar insallations are typically advertised as around 10yrs to break even, at which point you might need to install $4000 of new panels to keep running another 10+yrs

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe
No longer a wannabe - now an ASIC owner!

I adjusted the math. you need to find your sun hour zone to calculate annual average daily sun hours. I am in Florida and receive just over 4.5 hours on average.

~7kw*( average daily sun hours) = X kwh/day (~$ Z)

~4.5kW (4.5h) = 20.25kWh/day

At current difficulty and my averaged mining efficiency of .33W/GH, 1kW will run ~ 3Th of gear and will result in ~$.25 in BTC being generated per hour. So my solar setup, on average and at current BTC price and difficulty, earns 20.25kWh($.25) =  ~$5/day.

or something like that...

That's why I never have been able to justify it.  It's a long term investment.  If you look at mortgage 6-7 years on a house to ROI is not horrible compared to many loan duration for a house.

But as far as bitcoin 10 year ROI point just does not fit well.  So kinda 2 different investments.  If it's all still working down the road in 10 years he will be very happy getting free electricity from the sun.

That was one of the reason for going solar also, the system will generate enough power to cover my daily household usage and some excess. Hoping that it would allow me to run some gears at zero or very low electricity cost, now if Bitmain only shipped my Batch 1 S7 orders. Planning to post some pictures once I get the miners Smiley

Today we had our scheduled 3 month cleaning activity. Since we recently installed a high power pump on our cooling system, we decided to clean our dirty girls with horse-grade shampoo and industrial compressed air (life on the farm is very dirty).

WARNING: DO NOT TRY THIS AT YOUR FARM!

Before:


After:


Lots of bubbles:

Wow, this difference between before and after is huge, good job, they look brand new again!

I use a bottle of everclear. Works wonders!

We first have to remove the coarse dust and particles with compressed air:


We then use electronic detergent to suspend the remaining particles in a temporary solution and to blow it away:


The dust problem is slightly mitigated by our new filters:


Now we have to clean the filters...

That's a lot of dust in your mining farm, that can be cleaned within a day or less, may i know how many rigs do you have.
What is the total of the hashrate, i just checked your website and checked the contracts plans but not so much information.
The VIP benefits**, what benefits are you offering to the users, i would be interested in the VIP M.

Our city is nestled in a river valley of the nostalgic and rustic Moldavian hills. As such, it's very dusty during some times of the year. We have around 40 miners currently.
The total and allocated hashrate stats will be visible once we sell a minimum of contracts (otherwise it would show an unflattering small percentage).
We are going to add more information to our site as we go, user feedback always points out where this is lacking. The VIP benefits are listed on the contract page, for example  https://www.starthash.com/product/vip-m (basically VIP rank gives you access to all transparent non-proprietary information regarding our installations, including our lovely physical selves).

As beautiful and captivating as the mona lisa.

What are the green colored things in the floor in front of the racks?

Code:
A BTC mining experience with the best, proven record. 88 weeks + at 106% + and 181 solo blocks as of 05-29-16.
I will tell you a bit about two people who are unmatched in technical experience, troubleshooting, knowledge and time spent
online in the BTC world supporting not only pool members, but the entire community.
CGMiner is the software used on more mining equipment than any other software, and is written, maintained, with continuing significant achievements by these same two gentlemen.
The Pool and Database software used by many pools is written and maintained by them.
It is constantly under enterprise pressure. It handles multiple attack vectors and evolves staying ahead of every other cobbled piece of code in use at any other pool.
This is The Total Package in BTC Mining Software:
Kano of THE PPLNS CKPool located at www.kano.is
and CK aka Con Kolivas of THE solo mining CKPool located at http://solo.ckpool.org
If you are not mining at one or both of these pools you are not mining, you are searching.
Get serious regarding your numbers and evaluate the data yourself: https://bitcointalk.org/index.php?topic=1338693.0

On another note if you use the forum trust system as a gauge for buying or selling please take a moment to evaluate my personal opinions and consider how much weight this system sincerely helps anyone.
https://bitcointalk.org/index.php?topic=905210.msg13227629#msg13227629

Trust Abuse by dogie against many members is rampant.
He attempts to use it as censorship against anyone who dares call him out when he gives bad, or poor information.
He has given people advice which could or may have caused harm.
He offered to remove negative trust against me if I would post specific text. The text he requested is not truthful and I refuse to be extorted and blackmailed.
So should you.
Do your own investigation and confirm yourself if this is a one, two, three, or even four or five people incident and maybe he could claim truth or misunderstanding.
Once you see how many people have been abused by his methods I believe the truth will be obvious.
Everyone has an issue here or there, but few have so blatantly abused this forum's trust system.
Take Dogie's rating against me for example.
I have a blemish free record and have worked with many of the most trusted members of this forum with positive outcomes.
I have and would never buy / sell anything with dogie.
Be safe and don't use dogie's ratings system of any type. They are skewed by money and personal vengeance against honesty regarding his behaviour and comments.

Looks to me like foam insulation, I would guess a good thermal insulator as well as static insulator from the concrete floor. Am I right?

and the obligatory self promotion picture below Smiley



Well Winter is coming so the oppurtunity for DENIAL and running them a couple more months in 2016 as 'space heaters' at a small loss will delay the inevitable some
I guess (so sad so addicted) Smiley

well to be fair it is every couple of months Smiley

just the need to document them someplace (and the fact I get a bunch of hits on imgur so someone is looking at them) in that they will soon to be doorstops


I will limit such to every 4 months now sorry to offend Smiley

(jeez you do 3 posts over a period of a year of your rigs and folks get mad) Smiley

It's simply recycled wood. I didn't want to put the shelves directly on the concrete. The floor is not leveled and it kind of helps for the shelves!

Yeah. But temperature is not a problem since I've got enough ventilation and only one one row of shelves. I prefer to buy another exhaust fan for my facility if it becomes a problem Smiley (Cable management is very time consuming! And it doesn't last as soon as you move your mining hardware!)
