I am in the midst of developing a  power supply to be used primarily for mining.

It can be off grid mining in Daylight only. 
It can come with grid tie option more costly
If can be used with batteries more costly.

First option  Would be call "Daylight mining" option

Goal would be to  have  either 880 watt or  1760 watt setup

Would use a dc to dc power supply designed to convert the panels power to 12 volts.

Second option Is yet to be name  but would have a more expensive  dc or ac  to dc power supply .  It would mine for free in the daylight hours and you could pay for power at night or when profits are low just mine in the daylight.

Third option would be a battery pack but is costly and hard to implement. We may not build it at all.

Buysolar and I will be testing  this over the next few weeks.

 With  an avalon 841
 a two board s-9
 and a L3+  note to mods  please do not move this to alt coins due to the L3+ testing it is all I have that will let me test at lower power. note maybe I will test with a 1 board s-9 instead.

This idea is to pay one price for years and years and years of free power.  the dc+ac to dc power supply has a five year warranty the solar panels last more then 10 years.

More to come.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

I think the only household like item that would work for mining is if they put mining chips directly into solar cells and it is probably gonna be a small amount of mining chips per solar cell since solar generates so little power. The chips should be working 24/7 and housed waterproof somehow lol. Or better still, do wat tesla does and put solar cells into roofing with the chips. That might actually work, where the solar is located on the roof outside and generates electricity and the chips are located on the inside of the house and creates heat and btc. The good news is that it will never turn unprofitable haha.

This is a good idea.  A long term rebate never ending.  Just declining a bit.

Avalon would do well with this idea.

my partner buysolar and I are looking to develop a Pay One Price  solar miner.

Your have something here.  Build chips into a panel and mine a bit. Not bad.

Just don't forget that the support-component costs scale per miner, not per chip, so tacking on controls and power regulation for "a few chips" costs roughly the same as for a few dozen chips which gives the "few chips" miner a much higher initial cost per hash.

You know I'm not a fan of super high power miners, but there are practical limits to how small a miner can be and still be cost-effective.

This doesn't even look like science-fiction right now, it is more of a fantasy genre.

The solar cell manufacturers can't even reliably build-in the temperature sensors or other environmental sensors. Various radio-equipment manufacturers still can't reliably integrate electronics with antennas, even though the radio equipment isn't required to be maximally exposed to the elements.

Quite a few roof-based solar installs don't survive single year without sprouting leaks or other problems. Having recently seen the quality of workmanship on some of the solar power installations I observe a market regression in quality. Lots of them will require major repairs or will be completely torn down in the coming years.

Currently the flat, thin magnetics that would be required for power regulators are very expensive and are used only in high-end high-power CPU chips.

I'm not the one that would try to prohibit daydreaming, but people need to be aware of the distinction between dreams and reality. Otherwise it gets into the realm of either psychiatry or fraud.

the word [b]may[/b] covers a lot of bases.

My device won't be doing that.

It would involve panels  and dc to dc invertors .

Most of all it would be a pay one price getting you panels ,invertors, and you use a miner on the market now.

Most people would no have space for my setup since  panels  are 2 by 4 and give 220 watts.  so to run a s9 at 1300 watts you need 7 panels maybe 8.

which is a 4 by 16 foot space.  The idea of  chips built into a panel may work has nothing to do with what I am looking to develop.

your power cost is up front and you get about 1-2 dollars  a day back in power for many years.

would work nicely with an avalon 841 since warranty is 2 years.

you would need space in your back yard to run the gear. panels would install like this
these are 190 watt panels so 8 would do 1 s-9 for 5 hours a day or about 8kwatts a day

So  the avalon 841 with a two year warranty and your setup never stops earning since power is paid up front.

But 8 panels = 16 foot wide and proper sunlight. So your customer base is limited.

[quote author=philipma1957 link=topic=1931762.msg39307513#msg39307513 date=1528052239]
@ yankees yes  I can not put this in my own back yard  I simply have too much shade.

Not enough space for eight panels 2x4 each.

But If I can get an avalon 7nm using 400,500,600 watt settings this is a viable idea.
At the moment the avalon 841 can be reduced just under 1000 watts at  a low power setting.
Ideally  a sha miner  that has 3 settings of 400 500 600 watts  would allow me to build a 4 panel device vs an 8 panel setup
the key to this is I am hoping that  7nm devices under 1000 watts  are built by avalon.

At 2112  my setups  will not involve roof mounts or permits since the mounts will be portable.

off grid allows this in most any state.

DC to DC inverters?

Frankly, what you wrote isn't even sounding sane.

Trying to come up with a workable explanation:

1) DC to AC inverters
2) haul power off the field to some shed in a shade
3) rectify AC and regulate DC
4) feed miners short distance in the shed

could probably work if you buy recycled/re-manufactured/B-stock parts and still somehow manage to get politically-motivated subsidies for the cost.

I understand that not mounting on the roof would greatly simplify inspection for fire and electrical safety. But you would still require some inspection if planning on connecting to the grid or use the power in the residence/business abutting the field where all that is installed.

On a second thought I even don't think that the inspection would be easier to pass. Fire safety definitely easier; but the electrical safety would be worse: the field mounted electrical stuff would need to be made child-safe. I heard second-hand stories about that type of safety inspections and various lawsuits related to leaving dangerous equipment unattended.

Unless you have children, any children getting hurt would be trespassing anyway so sucks to them. Same reason I don't understand requiring extensive fencing around a backyard pool to keep other people's kids from drowning themselves - discipline is supposed to do that for me.

Anyway, I think the idea is to have a small enclosure (a doghouse was mentioned?) probably right at the panel, to reduce the need for inverters or long wire runs. Grid tie negates some of that, but if it's not required all you'd need is internet access and nothing else travels more than a few feet. Depending on how panels are rigged, voltages could stay relatively low/safe.

[quote author=philipma1957 link=topic=1931762.msg39317344#msg39317344 date=1528061057]
No dc to dc not dc to ac.  They exist and you would end up feeding 24 dc into 12 dc output.

They have one that can tie to the grid so it is techniqucally an inverter / converter.

Or a 12 volt output power supply that can use dc or ac.

It is more costly then the straight dc to dc converter. Which would only run in daylight.

You need to understand the value is getting. Up to  20 years of power with no additional cost.

And that it is not for an apartment dweller .  But it is for a person with some land,

If you are concerned about kids fucking with it then fence it like a dog run. After all the miner will be sitting in a doghouse :D

I will be starting a new thread on this soon. I brought it up here as we will be testing it the next few weeks.

Avalon says they want newer ways of using chips when they make the 7nm well a 400 500 600 watt miner would be good for this idea.

Here is a photo of panels these are 190 watt .

We have access to 220 watt now so 4 or 8 would be needed.

Hey Phil, this seems like a great idea if you can keep the cost down. Let me know if you're serious about it. I know many people in Asia that would like this if it makes sense economically. We get alot of sun all year round!

Yeah  we will be building a prototype soon.

The key  will be how many panels we can get "new old stock" panels  really cheap at auction. 

This means  210 to 230 watts a panel   panels are about 2 by 4

We can get a (dc or ac) to dc power supply  rated at 1200 watts this allows 24 hour operation and tied to the grid
We can get a dc to dc power supply rated at 1200 watts  this is for Day light mining only.

So  a 6 panel 1 power supply  can not do the s9  or 841 or t1

but  it could do an L3+  or a 2 board s9

We will be testing  8 panel 2 power supply setup on and off grid

We will be testing 6 panel 1 power supply setup on and off grid

Hi Phil,

Their best target market would be California because it is mandatory to put solar cells on the roofs there
https://www.theguardian.com/us-news/2018/may/09/california-solar-panels-power-renewable-energy


https://news.energysage.com/wp-content/uploads/2016/08/Dow-solar-shingles-624x365.png
Perhaps it can be used with the tesla roof. The mining chips should be on the ceiling inside the house, shielding it from rain.
Maybe if only use few chips and the chips were located far apart enough, there can be enough airflow such that u dont need cooling or it needs some kinda setup,a quiet one.


It needs to be wifi connected via an app and the chips need to be auto-configured to mine on its own. The owner should not need to configure it as most are lazy and not into btc. Perhaps can just auto-sell the btc every month for the owner and send the rewards to their bank account. Most owners are lazy. U may wanna market "Buy our solar miners and receive monthly payments to your bank account"


And some might this is nuts but if u consider that someone created a way to mine bitcoin just from body heat lol, this isnt so crazy. Other crazier things have worked.

Selling 100 dollar coupons (8units expire 11th June, 14 units expire 1st july) and 125 dollar coupon (2 unit exp 30th June). Selling at 20% of value

U mean u gonna just tie it to an L3 or S9? Wat about loud sound issues and most people wont be interested in mining?
If u can just install a solar roof that mines and auto sells the btc every month and sends it in cash to the persons bank account, they would sign up I would think lol. I wrote the last post just after reading only the thread title unfortunately. I thought u were going for the average person who is not even into btc, and not just miners.

Well, if u watch shark tank, u would realize things that are odd are not so odd after all lol. Good luck.

Please at least make it work with an S9. Also, it should be like a whole package including battery. Just a self-sufficient little mining-at-home kit. There is definitely a market for that!

Batteries are worthless. Not really but they make install  harder.

The key is to keep it simple.

We can get new old stock panels at a good cost.  The highest end panels  cost far too much.

But 210-240 watts panels  come up for auction at decent prices.

I have a prototype outside box that  should work..

  box\   right about where those ladders are.

we found a decent dog house  the fits 2  L3+  or 1 S9i   the box  size is fine  since panels are pretty big.

The test box is in my basement pulling 1350 watts running 2 L3+

Phil I cant wait to see it testing.

So  if you run it in day only  and I know NJ  gives an average of 5 hours of full sun in a day  your gear will average 5 x 1.5 = 7.5kwatts  and you project 20 years for the panels , but what about the power source?

20 x 7.5 x 365 =55000 kwatts correct?  at 15 cents a k-watt it is more then 8000 worth of pre paid power

10 x 7.5 x 365 =27500 kwatts which at 15 cent a k-watt is more then 4000 worth of pre paid power

5 x 7.5 x 365 = 13750 kwatts which at 15 cent a  kwatt is more then 2000 worth of pre paid power

So if your power supply/inverter/converter is a five year warranty  the panels and power supply need to be under 1500 maybe 1200 if you are a 15 cent kwatt user.

@ yankees  I dont recall if the power supply is 5 or 7 year warranty.

And your numbers have some accuracy.

We may have to target a 20 cent  or higher power area to be selling a viable product.

At the moment I have a wedding to attend and we wont be  doing any real testing until next week.

The enclose I designed will work for 1400 watts or less with no overheating It can be secured or moved.

It lowers sound of the 2 L3+'s

I get  the s9i's next week.

I like the idea of letting a higher power cost guy  get in the game.

I do have a prototype  that can hold 2 L3+ or 1 S9i

It is outdoors a doghouse available at Amazon.com

I am going to take a photo or two of it now.

about 28 inches long

https://i.imgur.com/Q5PMo2x.jpg

about 25 inches high note air intake

https://i.imgur.com/Jgo42qb.jpg

note air leaving
https://i.imgur.com/th1HHmF.jpg

pair of L3+
https://i.imgur.com/vERn9pS.jpg

could use 1 s9i I am waiting to get some to check how well it cools.

2 L3+  doing voltage mod pull 1360 watts and run cool

https://i.imgur.com/CB8Phmg.png

Note to mods this is not about  L3+  As my goal is to build this with s9i

s9i is cheap  my tests show power and heat can be managed for L3+
the s9i come soon  will show tests for it when it comes.

Sky has inverter/converter power source on order.

If we can  build a solar power source with this in the 1500 watt range doing 5 hours per day in NJ  where 13.7 to 16.7 cent power is common  the source gives 7.5 kwatts a day   that is 1.03  to 1.23  usd a day in power or 375 to  457 usd in power in a year.

The power source should have a long life  no batteries involved
Easy to setup  no grid connection.

the panels rate 20 years
the inverter/converter is 5 or 7 years.

So if we can sell it cheap enough it could work out.

Of course practicalities come in
maybe the ratings are too high .

maybe it does not last the timespan it should 

we won't know till we rest a bit.

Basically it has been tried already in the days when Bitcoin could still be mined by the GPU cards. Some guy did that in Germany or in Finland. It was linked on this forum, but either I can't find it or it is gone. He couldn't keep his setup working even a single full year.

The main technical point is that protection from the elements in a non-trivial undertaking. It is not only about keeping it cool, it is also about keeping it warm and dry when not operating or operating with constrained power.

The moisture condensation and icing will void any warranty for the electronics, unless you buy marine-rated equipment.

Additionally, the warranty on panels in the USA will probably be unenforceable. I've been told that those companies reselling and installing the solar equipment are intentionally created to go bankrupt, they may as well offer 100 years of warranty. That is apparently some political stuff more difficult to explain, which I don't fully understand. I didn't see the actual panels discussed in this thread, but I've seen some other sold and installed in the USA and they weren't designed to last.

I'm sorry for raining on your parade.

I didn't see the actual panels discussed in this thread, but I've seen some other sold and installed in the USA and they weren't designed to last.

I'm sorry for raining on your parade.

dude I have been using a 1.5 acre array  for years

works fine.  

here is the thread  https://bitcointalk.org/index.php?topic=1369207.0 the array has worked since april of 2016

we are simply looking at making a small version.

[...] Basically it has been tried already in the days when Bitcoin could still be mined by the GPU cards. Some guy did that in Germany or in Finland. It was linked on this forum, but either I can't find it or it is gone. He couldn't keep his setup working even a single full year.

The main technical point is that protection from the elements in a non-trivial undertaking. It is not only about keeping it cool, it is also about keeping it warm and dry when not operating or operating with constrained power.

The moisture condensation and icing will void any warranty for the electronics, unless you buy marine-rated equipment.

Additionally, the warranty on panels in the USA will probably be unenforceable.

You may be right about shell LLC's designed to block all warranty claims, but it is possible to shield electronics from wind, wet, and snow.

I'm not saying it is street legal, but I have used your typical eBay inverters (sellers like: ChargerAngel) to backfeed power into my residence.  The inverters are housed in marine battery boxes, with the top vents sealed with silicone.  It's cheap, and the inverters have made it through snow, rain, Nor' Easters, and hurricane Sandy.  Solar is pretty damn set it up right and forget it.  Completely different than setting up miners.

If you can find a good spot to lean solar panels up against your dwelling, you can do this.  You don't need to roof mount, you don't need fancy frames.  Use the space underneath the panels to house inverters and whatever other electronics you are working with.  Keep everything off the ground by a foot or two or three.

I haven't put a miner outside, but so long as it is elevated off the ground, and there is a decent plastic housing that is waterproof, I see no reason why this can't be done.

Also:  spray silicone can help so long as you let it dry completely.  As in apply it, go away for a week or more before applying power to what you sprayed.  Yes, I have done this.  All my Vega cards were stripped down, sprayed with silicone, Raijen Morpheus heat fins & 120mm fans applied afterwards.  Very quiet, cooler than the reference blower, and running just fine.

Try the silicone spraying on something very cheap.  Let it dry thoroughly.  Test it.

the panels we use are these

http://sepbatteries.com/ecosolargy-230w-poly-crystalline-solar-module?gclid=CjwKCAjw9e3YBRBcEiwAzjCJuolmm5yZWCBbii562Sy355bQTVhVhQZCgbk4m4QsQCvCwwwL5c7LMxoCsYYQAvD_BwE

they are 39 by 64  inches

seven are about   23 feet  wide by 5 foot 5

should do about   1610 watts which may do an s9i  will certainly do 2 L3+ on a bit of a down clock

The game at the moment is cheap power.  If you build the power source/panels for 1k it is viable plan with a path to profit.

Most people can't do this as they can not source parts cheap enough.

the cost for the panels on that website would be 7 x 100 = 700 so you would need to spend under 300 for inverter.

as for keeping the gear dry the big issue would be down time on the s9.  as it would be turned off most of the 24 hours. and run for 6 hours or so each day.

in the winter cool air may prevent it from starting when sun comes up.

Is there any system to stay away from?

First off laws rules and incentives are different every place on earth.


Some states in the US are great and have lots of incentives other states are not good.

So you need to check where you live for incentives and rules for solar power.

A couple of points:

1. S9i solar panel 'doghouse' design with 1400-1600w output would be great, thanks for working on it.

2. I looked into Tesla roof...it is horrible, cost like 100-120K for my house (50% roof, before batteries) while solar panels install cost 25-30K for the same wattage. Unfortunately, i would have to replace roof before putting solar on (roof is 19 years old).

3. I am in Houston, so no local incentives, which sucks...oil men, etc.

looks like 1000-1100 is more practical for various reasons.



working on a breakout board for a dc to dc psu that will give a stable 12 volts of power.

may need a cheap car battery to keep it 12dc volt stable

note the battery does not extend  your mining over night what it does is help out during rain/clouds etc

A place like Houston  would do 5-6 hours of mining a day  on the average.   

it may not be practical with margins so tight
