Who doing Solar

[kriptokyng]

Fixing to start build a small solar BTC Farm.
Who already doing it and whats your setup?

Thinking
6- Renogy 100 Watts 12 Volts Monocrystalline Solar Starter Kit
24- 100ah batteries
6- JUPITER 1500 Watt Continuous/3000 Watt Peak Modified Sine Wave Power Inverter
5- BitMain S9

wont work,

s9 pulls 1200 watts on avg

so you could only run 1 ,   and your only going to get 8 hours at very best at 600 watts @ 85% efficiency
your only going to be storing about 3000-4000 watts total , so only running that s9 for 3 hours at best

and 100 ah batts like the Walmart 104 ah hr are crap for this type of application might get 100 deep cycles at best

i have a solar mining setup but i just do gpu as asic is a power hungry beast

i have 11 290ah Deep cycle non spill-able sealed led acid batterys i got from a cell tower as they were changing the battery's every 3 years 40 of the 290 ah or 60 of the 190 ah are changed out

charging those battery's i have 8 300 watt commercial solar panels , charged by 4 mppt 80 amp units ,  even with this setup i only get 6 hrs @ 2400 watts @ 85%  or about 12kwh into the batterys,

now that its winter getting about 6-8 kwh --

you can do your setup but it will take years to pay off if at all ,
only reason i did mine , got the solar panels for free (they were presumed broken , but a diode fix was all that was needed )
and got the battery's all for 400.

I know that philipma1957 does mine on solar and he knows his stuff, i don't have enough knowledge regarding the subject but i am good with numbers, go ahead and tell me how much is that solar going to cost and i will tell you if it is a good investment ,although if I had to answer without knowing the solar system cost in your country, and by using the figures i know of, it seems like a terrible idea, the ROI on this thing will probably be worse than buying an efficent gear and running it on-grid.

I know for large operations and for tax proposes solar and mining do blend well, but as far as a 1.5kw solar system is concerned, it is probably a terrible idea.

You can make the numbers work if the government subsidizes the cost of the solar in one way or another. But without tax dollars helping out, you're looking at a cost of more than 10c/kWh if you use all the power from the array over a 25 year life. That's if you're doing a grid tied array and the power company is giving you even credit for the power you put back into the grid. If you are not grid tied then the battery system just makes it more expensive. If you are doing a huge industrial array it could be cheaper, but still not as cheap as a decent industrial power rate.

Forget batteries, get a grid tie inverter and use the grid itself as "battery".

Then, get enough panels maybe 2000watts or so to power 1 S9. Of course less than that works, but you will be saving very little.

You "could" go gridless and simply let it go off at nights. Don't mess with batteries as they are not cost effective. Maybe, just maybe Tesla's powerwall or similar, but not the traditional deep cyclers, they are just not cost effective.

And given an S9 is nowadays valued for like 100$, i see little point in going out of your way for such an expense with batteries.

TL;DR: Just panels + inverter or panels + grid tie inverter. No batteries.

exactly,

i have 3000 watts into a sunny-boy 2500. gives about 2-2.5 kwh when the sun is up after 9 ish now it gets dark at 430 so the daily kwh output is reduced but during summer it cranks at full tilt for 9+ hours. but dead south with proper tilt angle is needed to get the best results.

my battery setup is more of a labor of love , used mostly for gpu mining on old free hw. batterys reclaimed from cell tower. 8x 300 watt panels bought at auction for 15$ lot and amazon mppt chargers , its a cool system with an inverter & small cheep battery voltage cut off ciruts hooked up to a 200 amp solenoid .

pretty bad a** setup for $15, I've been considering doing a trailer or something portable to solo mine . A expensive scratchoff lol.

read my post to have an idea about solar mining.

it depends on how much you want to invest, and how many miners you will be using.
consider the space that you have too.
