Topic: GUIDE SETTING UP A SOLAR POWER SYSTEM (Read 12877 times)

Great prices for the U.S and even better prices outside of the U.S. Long story but this was one crappy decision by Obama that screwed over the international solar industry.

Yes, should factor "somewhat" in that element for now.

Are you figuring GreenCoin into the revenue analysis?... 

Hi Rogelio,
First we need to know the whole cost estimate of your system to do a profitability analysis.
Another thing is that 5000W power system may be ok if its in my area since I get a lot of Sun.
So that will depend on your region and the duration of Sunlight.
Before all, Mining is a bad idea for now and so Mining + Solar will end up as a bad combination for now.

hey allcoinminer,

do you think in your own opinion getting a solar generator set like a SSUVPR 5000W 96V Solar Inverter with Controller System (UPS Function) whole set to power one SP35 Yukon Power is a good idea?
what is your take on it? I'm all ears on your feedback.

For which country you want the details of solar panel distributor?
You can also try google search.

Anyone have a link to a decent and relatively cheap solar panel distributor?

Your points are very mush valid.
In my system I finally dropped using battery backups for the rest of the sun time and is using grid.
Battery back up will just act when in an emergency.

Normally in professionally installed battery systems they will only discharge upto 20% of the capacity.
So, the battery bank(s) will last for 10+ years even if they are not looking for breakeven.
They get ROI from their business by account these costs to customers.

Regarding Charging Time, atleast 10hrs is recommended for C10 batteries but we only get 6hrs.
So we are forced to charge in 2 days or in a single days with more current. The second one will shorten the battery more.

Here in the case of home miner or even home farms, the Solar + 24hrs Battery will never ROI.
But a Solar + Grid can breakeven in the long run, if and only if we can use the maximum power the panels generate.
Again, no mining device is available at this point in time to mine for ROI.

Inshort, just forget about "any" Solar setup for atleast this time.

You need to consider that for most battery types you cannot take the Ah rating and assume you can use 100% of this, because, cycling most kinds of batteries that deeply will permanently damage them. Be sure to carefully review the manufacturers tech sheet and find the max discharge depth, THEN calculate the "real" Ah rating from there. You can use this to calculate watt-hours or joules stored, which is a more meaningful piece of information for sizing your solar setup.

Also the 6 hour charging time above is unrealistic for a full charge for most battery types. Again you need to see the manufacturers spec sheets.

Cycling batteries between deep discharge states and back to their full capacity on a daily basis will also reduce their lifespan a lot more than usual as this is not considered standard operation. Arbitrary example: Most lead acid car batteries are discharged only less than 3% of their total capacity when starting a car, this will get them 3-5 years. Now take the same battery and discharge it 25-50% every 24 hours (if it's even possible to recharge it within spec limits that quick). Suddenly it lasts 6 months to 12 months tops.

A lot of people "make" battery storage systems for solar without researching how much they can drain their batteries, and how low of a voltage they can be taken. There are newer types which can take more punishment but there are always limits. I know a handful of people who've purchased various setups on ebay and of their own design only to wipe out $5k of batteries in half a year.

Pardon me for delaying the update with images and so.
I will do it soon, lazy me.
But you can ask me anything related to solar panel setup and I can guide you.
If you are taking support from agents or companies you will never ROI.
Do it yourselves by the support of forum people. I did it myself.
If you are using any good solar panels, you will get 1500W from a 2000W system during the solar time.
If you are running it 24/7 then you need a lot of battery AH and you need to charge these batteries during the day time everyday.
Batteries will never last more than 5yrs if you are discharging it to the maximum.
Else you need to buy a lot of batteries to make the discharge percentage lower.

For your need, 1400W is required 24/7 from this solar battery setup.
So around 2000W panel is required to run the miner during sun time.
Then for charging the discharged batteries daily, additional panels required.
If we calculate solar time as 6hrs (Max and too optimistic) you have 6hrs to charge the battery bank.
And your total charge backup requirement(or total charging required) is approximately, [1400*(24-6)] = 25,200 Watts (25.2KW).

That means, you need 2100AH of 12V battery. If its 6V then need 4200AH. Practically you need 3000AH atleast for 12V battery.
That's equal to 15 no of 200AH/12V Solar Battery. It will cost approximately $3500.

And to charge this much battery power during the limited 6hrs you need atleast 6000W panel. Which will cost around $4500.

Consolidating:
Panels required is more than 6000+2000 Watts Cost: $6000.
Battery 3000AH costs $3500.
Cable and other Misc: $1000 for this setup.
MPPT Charge Controllers: < $1000.
Total: $11,500 Plus
Now think whether you want to setup this damp thing.

Inshort when you add more battery backup requirement you need more panels, more cables and other components.
So, if you are sure you want to go for solar just go for a Solar + Grid setup and use 400AH battery bank for emergency backup.
That will fit the budget and will ROI in 3 to 4 years if used fully. I only recommend that if you want to go for solar.

Disclaimer: All the above numbers are from rough calculations without considering losses and practical conditions.
In practical setup you may need more panels and battery so the cost will be more than what estimated here.

Again Solar is expensive as of now.

The solar calculator online I used states I need about 6,600watts to run 2 S3's for 24hours a day.  I'm interested in setting one up.

Do you have picture and components of part and panel ?

Please share with us

As I talked to some agent at solar saleman he told me I need at least 6000Watts of solar panel to run 1000Watts PSU for 24 hours.

My question is if I get more batteries say like 4, so I can reduce the panel watts ( from 6000 to 4000 or 3000watts )

Help please.

Really want to setup for 2 ant S3 or 1 Ant S4 (1400w)

May be invest for farm of them soon.

Yes everything is properly organised for me.
Thank you, SUN!

Goodluck with you Build,I hope good things come to you

I'm not doing that because the output voltage from solar charge controller goes too high from 12V or 24V which the ant cannot handle.
So now I put DC-DC converters in between.
On one of the DC-DC controller its fuse is blown every morning when the sun shines bright.

on a side note: sorry for not putting the setup images, I was a bit busy and too lazy, but I can update it soon.

You're already going to be wiring the batteries in a 2-series-2-parallel configuration to get the 12V batteries to play with your 24V system, yes?

Why don't you just connect Ant blade #1 across one parallel set of 12V batteries, and Ant blade #2 across the other?

(Just check first to make sure the blades aren't tied together electrically, and install fuses anyway to be safe.)

amazing instructions, thank you

Can't wait for images. Very interesting stuff.

My system setup is complete. Its a 3000Watts system.
Next week I will update the system features with images in this thread.
Is waiting for the DC-DC converter.

On the solar end of things, as long as you are making metered energy (kWh) you can get free GreenCoins. Any and all interest please message me. I'll pay a 0.01 BTC for the next 10 producers to sign up. I am trying to find more producers for the GreenCoin network. There is nothing to mine. You get coins FREE coins daily for solar production regardless of the end use (internally used or pushed to the grid).

Easy to understand 1-page flyer

If nothing else, maybe after your operation is all set up and you're earning GreenCoins it adds a secondary revenue stream you hadn't previously considered, which is simply a bonus.

thanks! BDC
