Topic: Solar panel config for 24x 3060ti (Read 380 times)

For a setup with 24 RTX3060ti cards running at 3600 watts, you'll need a pretty robust solar setup to maintain that, especially if you're aiming for 24/7 operation. You'd want to consider not just the panels but also storage solutions like batteries to handle the load when it's not sunny. Over the past two years, I've been really into solar panels, looking into how they can save or even make money. A valuable source I found is https://solargenerators.to/, which has a lot of articles about solar panels, guidance, and even product recommendations that could help with planning and optimizing such a setup.

You don't have to do any engineering work to understand how much energy you need to power your mining farm, you can just hire a professional and tell them exactly what you want to run or do some research and get solar calculator online, there are many online and they are better than each other.

Assuming your live in texas which get 5hr full peak solar, means:
150w x 24gpu = 3600w x 24hr = 86400w
86400w / 5hr = 17280w solar panel you need and minimum + 86400w of batteries if you want go full solar energy, it’s basically minimum, you need morethan that to spare some power just in case you dont get 5hr solar peak per day, and yes its expensive to build, solar cell mostly get 25years of warranty and battery might life around 7year more or less

I'm only using a single Tesla Powerwall for my battery backup.  It wouldn't last long off the grid as the sole energy storage device for my operation.  I could go off grid during the day when the sun is shining though if I wanted.  That's a nice usage for it.  Also, any power outages won't immediately effect anything I'm doing.  The real benefit for mining though I would say is that I can store excess solar generated energy from sunrise to noon, and then once the sun goes down it uses that stored energy before going to the grid until 7pm when electricity on my plan becomes dirt cheap again.

The Tesla Powerwall is awesome.  I've had no problems with it whatsoever, and it provides awesome graphics and statistics about your power usage.  I would say that interface is almost more valuable than the battery itself.

The system software doesn't give an expected life for the batteries, but I believe Tesla stated it goes based off of how much usage you get from the battery.  I have mine set to only use about 40% of the battery on a regular basis as that gives me the desired effect, but if I recall from memory the batteries would last 10 years using 100% daily, so I would expect mine will probably last in the 15-20 year time frame.  By that time it is possible it would have paid for itself if electricity continues to rise, but I think being able to go off grid and continue to allow your home to function during power outages is the likely main benefit.

Og, looks like you have been solar since 2017.

 Have you been using batteries the entire time? Has there been any failure?

Does the system software give an expected life for the batteries?

Ya, I've been doing that for a while...

The problem is that wind energy is even more unreliable than solar, not to mention the upkeep and maintenance involved is quite a bit more than solar.  I found that for mining purposes, wind energy is nearly useless and with the technology available today I honestly think you are better off just using energy from the grid.  The only time wind turbine energy at a small scale would be beneficial in my opinion is to charge batteries where grid energy is unavailable.  I'm sure this will change someday as the technology improves, but for home users it just isn't there yet.

If you're considering any type of alternative energy powered mining operation, the main expense is going to be batteries.  Grid tying eliminates that, which is why my earlier comment quote below makes a ton of sense.




That's why you remain grid-tied so miners can operate fine off the grid energy during cheaper electricity rate times of the day, like when the sun isn't shining.  However, during times of overproduction, say when you're at work and the sun is beating down on your solar panels, instead of overproducing energy for the grid, you're burning it with mining. 

I have no knowledge about it, however why only 24kW+48kWh battery, when his rigs would need 3.6x24=86.4kWh/day?

thank you

While this is do-able (and i have a couple test solar panels) you have to factor in the costs of

SOLAR PANELS
DEEP CYCLE or LI-ION BATTERIES, LOTS OF BATTERIES
MOUNTING EQUIPMENT
COPPER CABLING
INVERTER
GRID CONNECTING EQUIPMENT
AND LABOR

to put it into perspective, I have a weak 100w solar panel on my roof which i use for random hobby stuff (and keep batteries charged up). I hooked it up to a RPI and it couldn't keep that little thing running overnight... Maybe lack of batteries, but still... How many more batteries will I need if i cant even run an RPI overnight??

Yo I think wind power has more disadvantages that solar, you need to consider where to build your farm and the wind power because they are less effective once there isn't enough breeze in action, solar panels wins over wind maybe you can find wind Vs solar power online for some comparisons.

at 24 x 150w its 3.6Kwh. so you need to produce at least 32.000 Kwh/year.
In order to do so, the minimum with the best orientation / inclination is 24 KW installed with a bare minimum of 48 Kwh battery pack . Cost in euro for such, vat included is maximum 2400 euro/kw + 1000 euro/Kwh for the battery itself. So its 57600 euro + 48000 euro  a whopping total of 100.000 euro
 
So, at least in my country, this is NOT a civil installation, but an industrial one.

In fact the biggest similar I did ( and I do PV for a living) is just the half of what you think of.

A Fronious 24 10KW, with a 13.2 Kw of Sungrow panel installed and a 22 Kwh Byd battery

This is running in a NZE house and every watt that is not needed for the house goes towards 2 rig of Manli 3060ti Lhr that are operating with 2 different configuration: High, low  for each rig.
The BYD interface does give information on the battery charges
When the battery is really low, mining is switched off. If the projection indicated that battery will be low that day miner is switching on low(Ton )

Keep in mind that people did that just because of the sizable incentive of converting a normal house on a NZE house. Mining isn't not what's driving this, its just a nice way of optimizing the ROI  

I plan to use green energy as well but with wind turbine, solar panel is good but the price per watt produced is too high, between 1~2 euro while the wind turbine come with 0.50~1 euro the watt.

Well said. From an energy perspective miners make a good sink for absorbing overproduction.
But from a mining perspective you want the miners running 24/7.

If only that pesky sun stayed up 24 hours a day...

I think rather than looking to install enough solar panels to mine on 100% renewable energy, people should think of mining on renewable energy as a way to elevate their financial benefit from overproduction of electricity.  For example, there are a lot of solar systems in use throughout the country that overproduce electricity during certain hours of the day.  Currently, many of these producers get compensated very poorly for energy they add to the grid.  Mining crypto is a good way to take that excess energy and profit at a much higher rate.  Additionally, at night it can save wasting energy on heating and instead put that toward generating crypto assets.

So instead of looking at mining as a problem that needs to be solved with a ton of solar panels, look at it as a solution for how to benefit from excess energy production. 

You need to do some serious engineering to determine how much solar energy you can get
in your location, considering the climate, lattitude, clouds, etc.

IMO pure solar is not suitable for mining because it's not a reliable energy source. A hybrid solution with
a grid backup is better.

I think OP needs double of that power from solar energy because of battery backup, if the mining rig draws 3600watt then the solar panels should produce more than or double of this 3600 watt that will charge the battery full and still be able to mine at the same time, sun won't be up forever it's only a matter of hours

You have 24 separate 1 card rigs?

You have two  12 card rigs?


It looks like you are saying 24 one card rigs. With the mobo and the fans you will be close to  200 watts.

200 x 24 = 4800 watts a day or 5 kwatts.

if you have a 2kwatt solar setup grid tied. and you have net metering. It will generate 2 x 4 = 8  to 2 x 5 =10 kwatts a day

So a 2000 watt setup grid tied could do a rig 24/7/365

panels are 300 to 400 watts. so 5 to 7 panels could do the 1 card rig

you need an inverter and to be grid tied.

I've read some comments in this alt mining section where few people said they are using solar panels for mining crypto I want to know how many solar panels is needed to run 24 RTX3060ti ? I use 150watt per 3060ti so in 24 places that's 3600watts but what's your best solar config for this build?
