Nice thanks for sharing, placing this in a hot climate with access to a decently clean water supply would be great.

Not sure where your attempt at off the grid power is but a nice rain catch reservoir would add another bump in utility savings. I guess it depends on the type of heat exchanger they are using, if it's shell and tube you can get away with a lower quality of water. A plate exchanger not so much the water path tends to get fouled up quickly.

Good luck

Nice one, which one is better solar or wind in compare to money/energy?
I also thought how many SportsArt ECO-POWR™ G510 Indoor Cycles you would have to have to power 1 antminer (anyone calculated? let's assume 2h a day for 1 man?)

Solar is hands down the better investment.  I don't think the wind turbine will ever pay for itself before being decommissioned, but it does look damn cool.  Having the infrastructure in place is also great for future use, should a more efficient wind turbine be produced.  The wind turbine does outperform the indoor cycle though, which is why I didn't do a direct comparison with statistics.  Let's just say this project has given me a new respect for how affordable electricity is, and how awesome solar power is.  My legs are definitely the biggest beneficiary of the cycle, as I've been riding it for between 5-15 minutes every day and am getting stronger thus able to ride with a higher resistance.  The higher the resistance level, the more energy it produces.  For example, barely peddling on a high resistance setting produces way more energy than peddling like a madman on a lower setting.  However, it would probably take 40 of these bikes peddling nearly around the clock to power an antminer, so it is not a realistic energy generation solution without owning a gym and charging people to use the bikes.

Thanks for the reply, do you own this cycle?
Anyone knows maybe water turbine? Let's assume you have house near river would it be better than wind/solar?

Hey OgNasty,

Have you looked into/read up on High Altitude Wind Generation Technologies?  It's been discussed in very isolated circles dating back to the late 1970s, but never implemented. Only now are companies starting to really look at it's true potential. Some interesting tech startups are emerging with interesting ways of harnessing wind turbine energy generation with the use of kites flown at high altitudes.

Theres a number of projects that seem far fetched, but I think in the not so distant future High Altitude Wind Generation is going to be a huge industry; simply because it makes financial sense on practically every level.

I actually went out to Joshua Tree CA a few years back and drove through the massive Wind Farms on the way near the park. Did a lot of photography, got up close to the massive turbines, pretty crazy. Standing directly under a full sized wind turbine while it's running, you literally feel the shockwave, like a very low sounding thump from a woofer; run through your body as each blade crosses down and over you 20 feet above.

But high altitude concepts are pretty amazing, in terms of what's possible with very basic concepts simply put into place and used.

The two that stand out to me are the Laddermill: https://en.wikipedia.org/wiki/Laddermill and Angle of Attack Pully systems.

Second; The concept of constructing a large kite which is the shape of a cylinder; The cylinder has vents, similar to how a parachute is able to open vents to turn; which when flown forces the Kite into a fast spinning motion. Tethered with a high strength low weight cable, the kite is flown up to +20,000 feet; and if geographically positioned correctly; you put the kite into the Jet Stream. A fairly constant 200+ MPH wind-stream that never stops. This of course forces the kite to spin very fast, which creates tension on the cable, and the cable spins and turns the generator which is based on the ground. The economics of this are amazing considering that this eliminates much of the costs of ground based turbines; which require large amounts of very heavy materials; the ground pole; the blades, etc, plus lifespan and replacement of such.

Last, but not a favorite;

The Angle of Attach is like a fish on a reel; the kite is pitched back to catch the wind; causing it to reel outwards; which spins a generator, when the kite reaches 50,000 feet; the cable tension is released, and a weight moves towards the nose; pitching it foward. So the kite no longer is being held, and pitched down. After it hits 10,000 feet, the cable is drawn in; (kite is now at low altitude but distance wise very far away); and as the cable is drawn in with the nose down; it maintains low altitude and returns close to the generator. Then the cable is pulled tight, and the weight is moved to the aft of the kite, pitching it back, creating lift, back to 50,000 feet... which as it pulls out drives the generator.

Of course this done on a large scale; thousands of kites like this, would produce massive amounts of energy; at a much more efficient rate; harnessing the 200 MPH winds at high altitudes and not requiring all the heavy steel of today's ground based wind turbines.

Ships could also use them at sea; a generator on a ship, with a kite single 10kw generator on board.

And of course; 100% coordination with the FAA and flight traffic patterns- just to keep all those frequent flyers flying.

But read through this thread; interesting stuff, and good ideas here. Just thought I'd pass this info along; in case you hadnt heard about it, as it's only recently been starting to catch "wind" and still only in small circles. But promising.

Hope you're well,

Cheers!

No.  I can't imagine something like that would be possible for me where I am.  Sounds cool though.

I have received a "permission to operate" notice from the electric company.  I assume this means I will soon be granted the ability to begin using the Powerwall for energy arbitrage.

I now have 1 entire year of solar array data to look at, so I thought I would post some stats.

Energy Produced in first year: 17,976 kWh
Estimated Cost Savings in first year: $1,995.34
Estimated Time to Breakeven: *10 years

*with average annual price inflation factored in

That's awesome congrats.

I was wondering what is the estimated lifespan of your solar equipment? Also estimated repair costs. Would it likely push the breakeven to 11 years or something like that?

No. It’s got a long warranty. I’m not responsible for any repair costs. Should last at least 25 years. I also expect electricity rates to rise faster than predicted. I’m confident it will pay for itself in under 10 years.

That's a great deal, when you take out repair costs and consider warranty.

I'm sure your right about energy costs going up, and really nothing better than going green.

What are some trusted brands or vendors currently for lithium batteries for use in storage with Solar Panels in your experience?
I have had an itching to start up a little single miner project using night time only mining.  Not really for profit just for fun and learning more about solar.
Plus at night you get lower ambient temps and in some cases use the heat.

First off I would like to say nice work and that I'm also into mining big time. I also design and laminate my own solar panels from scratch. I use the Sunpower Maxeon c60 cells you're using in your panels. I'm also an ex Nuclear safety inspector, SCE at the San Onofre Nuclear plant.

My concern is that you're claiming all this green savings and how your Solar Panels are powering your Mining Rigs and you make it sound like you have an energy surplus. Yet that 11.2kW array on your roof is the proper size for your house and no more. It's probably allowing you to "almost" break even for you homes electrical needs when you add in summer air conditioning needs. 17,976 kWh / 1,498 kWh per month or <50kWh a day. Those are your stats broken down.

As for powering your mining rigs? Let's be honest. Your home alone without the miners is probably averaging 50kWh's a day. I average 60-80kWh's a day without mining at my house is 100% LED's.

Your rigs alone are taking at least 133 kwh's per day + about 50kWh's per day for the rest of your home = 183kWh's a day on average for the year. I'm sure I'm off some.

You're  MINING HARDWARE:
1x Bitmain Antminer S9 (link)     1,340 Watts
1x Bitmain Antminer R4 (link)       845 Watts
2x Bitmain Antminer L3+ (link)      800W x 2 = 1600 Watts
1x Bitmain Antminer A3 (link)     1,275 watts
2x Radeon RX Vega 56 (link)         210 x 2 = 420 Watts (500W counting the System they're running off on.

Just the Mining hardware =  5,560 Watts x 24 hours a day = 133,440 KWh's Per day and I'm sure I left out many things like the power draw from the power supplies needed to power the Antminers or any additional fans and cooling.

My estimate is that your solar panels are supplying only 27.32% of your homes total energy usage.

Also, you mentioned you're already at $40K in cost and saving $1,995.34 a year (btw: 11.1cents per kWh) That's over a 20 year break not counting tying your money up with no interest and inflation eating the value. Those 2 power walls are going to need $7K worth of new batteries every 10-12 years. Your solar cells will likely hold over 90% power after 30 years.

Sorry to sound negative.

It would be awesome if you would post your actual electric bills.

I learned you can find them at motorcycle shops, most performance bikes have switched to them.
$200 will get you 12V 30AH 480CCA 80% or more Depth of discharge, 80% round trip efficiency, under 12 pounds.
Not sure what to use for a controller for LiFePO4 though, seems they have not caught up too well.

Any current recommendations on the most efficient solar panels, or is it such a slim difference it doesn't really matter as long as the price is good and it doesn't break ?
So far got lucky with $190 grabbing a 100watt panel which puts out exactly that in perfect sun.

Your calculations seem to be correct.
I am running about 200kW DC Solar and we are mining with about 20kW Hardware, growing to about 50kW until 12-2018.

So far i cant tell you the solar coverage ... maybe in september all counters are installed and when the logging works for some month i will make a prognosis.

At the moment i try to calculate the costs of investing in Batteries to use as much solar energy as possible.
We are somewhere between 200 and 300$/kWh storage costs i think...

But on the long go its very interesting and the ROI should be <5 years, if solar is available and "for free"...

When I was doing my research, I found that SunPower seemed to have better efficiency and warranty support than their competition.

Are you able to charge the Powerwalls with grid power, or only with Solar generated power?  Also, does the Wind turbine plug into the same Inverter as the solar panels?
