sadly so far it is very hard to actually charge batteries.

You can find cheap regulators :

I think you are vastly overestimating what Power you will get from a solar panel.

It's all about how much and where you invest off course , but even this old article shows how much potential solar power has :
http://www.huffingtonpost.com/michael-graham-richard/can-we-power-the-whole-wo_b_104355.html

We could have "free" global solar energy
If you google Gobi desert + solar energy you see the Chinese understand that:

You could pump some water in a high ground reserve and when you need power, use the gravity and water to power hydroturbine! Grin

I laughed. Yeesssss of course.... A kinetic battery, why not?

Let me just pump 10 pool worth of water over my head, to last the night on my S5 Tongue

Just wanted to share and keep you interested.

Thats really cool, but when i did research, the prohibitive cost was the yearly upkeep of short lived and expensive batteries. I would love to learn an alternative/cheap way to store power, however.

i hope to do something similar

so far i have found solar panels are on all the time even at night. There is always light. I wonder if solar panels also pick up infrared, which is emited by all life. even humans.

sadly so far it is very hard to actually charge batteries. Not sure why.

currently i have one 13v 108watt solar panel, 6 volts at night and 10 -14 volts at 11am - 8 pm.

in theory i would need 4 of these panels to remain at 12v's 24/7.

I think you are vastly overestimating what Power you will get from a solar panel. What matters is not an open circuit voltage but Voltage * Current. There will be no power available at night & even during daylight hours you will see the Power increase and then drop off again over a 12 Hour period. Exactly how this happens will depend on your location and how clear the sky is etc.

Here is an example of what to expect.

It needs to hold 12v to charge batteries to usable power.

all you need is 12v to convert to 120v ac. And you can run w/e you want.

watt hours. and total watts in general dictates your run time.

300 watts on a 1200watt car battery can run up to 3 hours. put in line to that 1200watts from solar and it could extend that time.

for my project i hope to input more free energy ideas. tesla towers, earth power, water power. wifi recievers.

I've found more videos pointing a camera at these devices, but none really telling me how to design the circuit. and what specific parts i need. It looks like i can salvage much of it from tv's monitors and various electronics.

So far i've learned that we are gonna need x2 more power in then what we draw out of it at minimum. so we should plan for this.

Good luck with this idea. I think you need to figure out a lower price for the battery for it to be good.

Thank you and indeed price is still bit high.

http://www.bloomberg.com/news/articles/2015-06-02/panasonic-to-head-to-europe-with-battery-storage-after-australia

The growing intrest and markt will hopefully lower price in near futher.

yeah i think i heard somewhere they are testing out new battery tech to help reduce cost significantly in the future, which would help this project immensely

I'm not right up on power pricing & structure in your area but here's an idea to try maximise ur power & save money..

First i dont know how long it takes to fill a telsa battery so please take that into consideration.

Do u have on peak or off peak power available to u?

U could buy enough battery packs to charge using grid power in off peak times so that u could run them all the time & even mix them up with some solar panels to reduce that cost

Only want 1 battery cause 7kWh battery should be enough for house consumption.

Two prices
annual (euro): 92,92
Price kWh peak (euro-cent kWh): 11,54
Price per kWh off peak (euro-cent kWh): 5,25

Only night
Price kWh (euro-cent kWh): 4,45

Setup:
At night => battery loads and miners run on 0.0445 €/kWh
At day => miners run on battery + solar panels 0.0445 €/kWh or less

I asked for more specifications on battery but no reply yet.

Yes indeed you could couple more battery's

Thank you for your comment

Just wanted to share my link and gather some helpfull information if possible

http://mouseion.weebly.com/

The return on investment (ROI) date given on your site may be a little optimistic. You have assumed there will always be 25 bitcoin per block, ignoring the halving mid next year to 12.5 Bitcoin per block.

Your ROI breakeven, at $240 per Bitcoin, may be closer to 900 days rather than 615 days.

This halving is ignored by a number of the ROI calculators. At least with the coinwarz calculator you can experiment with the number of Bitcoins per block.

Yes you're right , it's optimistic, not full worked out plan , still need to calculate electricity , inverter, psu, cooling system and anything I forgot.
As stated on site "can vary greatly".
http://bitcoinclock.com/
For what I understand from it, it also means BTC price should go up considerable, being an optimist ofc Cheesy

So in short, your goal is to "optimize" your use of Grid electricity based on time of day pricing. On Sunny days you hope to minimize or eliminate use of grid electricity during the daylight hours.

You are NOT trying to use Solar exclusively for your mining enterprise.

No I'm not , yes it is possible , you start to sound very negative for positive post with no angles, I don't mind, keeps post longer on top, serving the purpose why I posted it in first place.
Like I said in previous post , it's not full business plan, so yes you need to figure things out for yourself to, for your own need or goal, if you have concrete questions I try help you answer them. The mining is very new for me, that is why I ask help about it and is only needs to an end, to get ROI faster then 7 a 10 year needed for normal solar installation.
My goal is to have asap an off grid energy supply that covers my electrical need in my own home, it is not an enterprise for that you need more m² solar panels more battery storage and more miners, my needs are covert with 1 battery any excess would mean extra costs I don't want to invest atm.

There are more similar projects to been found , but with multi car battery's that have full cycle, but isn't very user friendly.

PS Made some post on my blog to , you're free to read and comment them maybe you understand my motives better.

Hi,
Where are you at on this project. How many panels per 1 tesla 7kwh power wall. Or is per antminer say 1 S5. Looks like 2panels at 266watts right. Oh no just read on Bloomberg that the tesla battery doesn't do to well with solar. Still thought I think it was just the government regulation that a small time electrician wouldn't know.

http://www.bloomberg.com/news/articles/2015-05-06/tesla-s-new-battery-doesn-t-work-that-well-with-solar

I'm only advertizing atm and spreading the idea.
It's not full business plan ofc, just basic calculations for idea

About the article as stated in the powerwall documentation you need an inverter anyway , a good Sine Wave Inverter with Battery Charger and Transfer System like Steca XPC would solve that problem, but ofc that's an extra cost.

Hey Valkir thanks comment

I don't understand how a 7 KWH battery can support 4 S5's (well over 2KW) overnight. Isn't the TeslaWall going to go empty about 3 hours after the sun goes down (maybe sooner).

Will the solar panels supply the 2KW for the S5's during the day, AND charge the Tesla Wall? I don't know how much sun you get where you live, but my guess is the Solar + TeslaWall is really better sized for a single (maybe two) S5's, unless you are getting well over 12 hours of full sun per day.

Can you elaborate on how you figured this out, or is it primarily budget driven?

Thanks for pointing out , yes you're correct for full cycle you need more battery's or less miners.

Yes it depends on geographical position, so if you live on either poles you wouldn't be able to mine for months, on equator it means you could easily mine more hours on sun. Also local economic and politic will have his influence, so I have for my own project that is sketched out on site also the possibility to use cheaper price kWh at night, my setup is meant to run on night price and charging at night running on solar and battery in daytime.

Woah that is a cool project. I suggest that you don't worry too much about breaking even. There is a lot of talk about the next gen of miners that are suppose to be coming out sometime in the near future. They should be more efficient than the s5, so you may want to start by getting the solar panels set up and see if new hardware comes out.

Also a with a novel project like this you may be able to get a manufacturer involved. Try contacting them, they might provide you with hardware at a discount. Who knows, they might work with you. This could make a really interesting promotion for the next gen of hardware.

Thank for your positive vibe , and yes I contacted them already but no reply yet

Quote from: Amph on May 27, 2015, 08:12:57 AM

then stay with your current s5, they are the best in terms of efficiency, also with one 1500 corsair psu you can power two s5 very well not so much with a s4, it would be too tight(1400 needed vs 1500), it would stress too much the psu

No specifications found about power outlet of the powerwall so bit in dark about that, so didn't look in specific psu but I take note of what you said, thanks

Ps To moderator why you put my post in sub catogory , this isn't speculation , I found previous attempt with car battery http://gwl-power.tumblr.com/ what is basicly the same, only cause of new technology I think this can be done more easy so private home owners could have total grid free electrical power payed back in less then two year if that is the goal no other setup is payed back as fast, but this can be applied to bigger companys

there is only antminer s4 which is not exactly the best, it's a bit worse than a s5, but seeing how 1 can do more tera hash, it is better for density, in theory you can fit more hash power in the same room with those

Thanks reply , cause I want closed circuit the power efficiency is importend

S4 has Power Efficiency: 0.58 J/GH (at the wall)

S5 has Power Efficiency: 0.51 J/GH (at the wall) batch 5

or is that irrelevant ?

I actually was referring to the s5 batch 6 where I can only find the bulk price atm
