What is Cost for Solar Panel for 24 Volt Battery 100 Amp

Time......

How long do you want it to take to charge your battery?

a battery of 24 volts 100 amps is incomplete info too. (Maybe 100 Ah?)

You ncan charge your battery with whatever small or big panel combination.....

that's why time counts your money.

Guru

You said your self Guru,but u don't know what mean 2volt 100amp it is 100AH.

I want continues charge like AC inverter.

What is solar panel cost in India

Thanks

shindvs

Dear Friend , you do not seem to know difference between100A and100Ah. The Ratings are based on duration like C10/C20etc. You have not mentioned what type of battery it is.Deep cycle flooded or VRLA batteries or GEL battery?Is it Flat plate or Tubular? It was not right for you to be rude and that too not providing required information.This forum consists of many distingwished persons and experts.After doing some search in Google etc one should put any question and in proper language.

Dear shindvs,

One thing we have not changed. That is 100.

You are a member, just as I was once also when all the CR4 participants gave me a welcome to join them. I appreciated this a lot.

Sometimes people ask odd questions, give strange answers, but most of the time you will get the most help to make up your own mindset or decision.

I am a straight Aryan myself but the guru name is a label you get once you have posted (forgive me if I am wrong - 500 or) 1000 times.

"A" is meant to abbreviate Ampere

"h"(no capital letter) is the symbol for time - here exactly 1 (one) hour.

---------- just as an example:

consider your battery as your drinking glass with water. Every time your power goes off, you drink from that glass and after a while it is empty.

You can fill the glass back up with a fast delivering hose or drop by drop.

For this purpose I entered the word "time".

The battery of 100 Ah (ampere x time) NOT A/h, AH, or A/H. This is to tell you how big or powerful (capacity) your battery is (or back to the example - how big your drinking glass is)

Theoretically with a full battery, you can use power (draw a current) like 100 A during 1 h, 50 A for 2 hours, 1 Ampere for 100 hours.

In order to chose your panels (but also the batteries), it is important to know how thirsty you are or how much you will draw from your battery when the power interrupts.

This is what you actually need to foresee.

Panels supply about 120 watts/m2 in good sun, good for about 10 amps on 12 volts

You'll need 2 panels in series to get your 24 volts (or more) to feed your battery charger- regulator, the amperage remains the same (if you end up with 8 amps, feel good about it) For the example let me keep it @10 A.

This size panels (in series) load your batteries completely in 10 hours. (with sun)

Two (2) 12 Watt, 12 Volts panels will take 100 hours.

This is theoretical because you do not unload your batteries completely (unless you want to throw them away after a few times) - So you cannot use the 100 Ah of the batteries, but only a disappointing small percentage.

I hope you have now some inspiration to ask more questions, or better to think about the answers to get more useful information. I feel no offense. Thank you all and I wish you all a best 2012.

See one time you said it is 12volt X2 Number battery in series it make 24 volt battery , battery ampere wont divide it remain same.

My inverter is APC Indian manufactured 800 VA sine wave inverter when power goes of i switched system trough MCB miniature circuit breaker bring my house on inverter with battery on line until AC power restore back.

There are two battery in series it give me back of 6 hour for house hold appliance i.e. lighting ceiling fans and refrigerator etc.

My batteries are 100AH 12 VOLT 2 number in series

What you have done is to insult someone who was only trying to help you. That's rude! You're off to a bad start here, having insulted someone in both your posts. But, that's OK, I'll still give you the answer.

The cost will be approximately $136.00 USD per square foot of panel, per cubic watt of power produced, during the day.

At night, the cost goes out of sight.

I don't want insult any one here, as per name guru mean teacher, professor in old aryan language,

I mentioned it is 24 volt 100amp battery. no need to specific 100AH.

But what you mention 136 USD that cost must be in USA. I want cost in India.

Thank & Cheer

shindvs

Here are dealers in India...price is quoted at ~ INR - 67/- PER WATT ( Mumbai Port ) ...

http://www.alibaba.com/trade/search?Country=IN&SearchText=price+per+watt+solar+panels&IndexArea=product_en&fsb=y

While my answer was just a joke, as are your manners, why couldn't you simply convert the price given in US dollars into Indian currency, instead of demanding that someone perform this simple conversion for you.

I suggest that you read the FAQ's at least twice and then act with a little humility instead of expecting someone to do your work for you.

Also you might demand that someone define Guru for you, and what it means here as we are not speaking "old aryan language" here, but rather modern English.

Please then put your nick name as guru, it confuse anyone, I can search in Google, no big deal.

I don't want insult any one, if u previous there insult of me by some Canadian. Because I am Asian.

what is it competition?, just share ur knowledge

I am Sr. instrument specialist in crude oil industry, we do lot of process instrumentation trouble shooting day to day as routine job

Sorry if i hurt any one.

Regards Shindvs

You should understand one thing here. It does not matter if you intended to insult people, you have insulted people. A true gentleman never insults unintentionally. A man aspiring to become a gentleman apologizes when he insults unintentionally. A belligerent fool does not care if he insults anyone. You've finally recognized here that you have insulted people in this thread and have made a simple apology. This is a good improvement but it may be too little.

Now let me try to explain in clearer details why knowledgeable people here have been insulted by you so that you might not do this again. Your initial question used valid units of electricity that provided the wrong information to answer your question. Somebody then politely asked for a clarification by asking if you meant the correct unit instead of the unit you provided. Instead of clarifying that you did mean the unit ampere hour instead of ampere, or asking for a clarification of the meaning of an ampere hour you attacked the knowledge of one who asked you the correct question. This tells us not just your idea of a polite discourse but that you are incapable of recognizing sound technical information when you are given some.

In short, you have poisoned this well of knowledge called CR4. Fortunately this poison will only affect you and your questions. Your best bet is to never return to CR4 with this handle again.

Good Bye!

dvmdsc Guru

I am so sorry if I hurt you. I don't mean hurt or check your knowledge

Please forgive me

shindvs

Oeps, next time, I definitely will think twice before posting a question here….

Please don't shoot … ;-)

I didn't mean to rob your time….

I am Sr. instrument specialist in crude oil industry, we do lot of process instrumentation trouble shooting day to day as routine job.

That statement, in itself, would signify that you would have the basic knowledge of fundamental AC/DC electricity. I don't understand how someone with your credentials have such a hard time understanding what is being asked from members. Even with English as a second language, I would think that you would or could do a better job constructing your questions and replies.

I'd be curious to know, how much down-time your company suffers from your "trouble-shooting skills?"

AH?? That's an Amp-Henry right?

Are you using a wire wound battery?

If you want the cost of that PV arrangement in India just add freight, insurance,import duties and brokerage.

Let me know if you need more rope. I still have some.

Hi.

The 100 Ah, stend for: The Battery Bank, should give for You ONE (1) houre 100 Amper out put, with any voltage drop, what ever the stated voltage on the Battery Bank. Nothing to do with (Henry)

Old Magyar

May I know what is this Aryan Language? I have not come across this language,being an Indian myself.If you can guide me to some books or website I will be very happy.

For energy storage purposes, the more meaningful battery rating is amp-hours (AH). We think that you probably meant a 24V 100AH battery.

For engine starting applications, the cold cranking amps (CCA) are also important. It is also possible that your battery has a 100 CCA rating (although that seems a bit low.)

Collectively, we need to clear up this ambiguity; only then can we move forward.

You need to give more information. Location, use of battery, why you want solar at all if you have access to line voltage, etc. Ramble on, tell us everything.

I want use solar panel instead of line voltage, is there any harm? installing solar panel, green energy. I can save my electric bill for charge the battery. I got place in my building to terrace. any how Mumbai is always sun rays except rainy seasons, my battery is 12X2 volt lead acid battery. Battery ratings is 100A/h. Battery manufactured by indian company name AMCO.

Regards Shindvs

Doesn't the rainy season last for a few months? Do you have cloud cover all day?

If yes, you will probably need to stay connected to the utility company to provide you electricity during that period because the solar panels will not give you much power during that time and the batteries will not hold enough charge.

In this case, do you intend to sell electricity surpluses (during the sunny season) back to your utility or to some neighbors?

These are important consideration because there are legal and safety issues with doing so. Just check them out before investing.

Your panel needs to consist of a series/parallel combination of cells that will produce ~28V (or more) to be able to charge the battery. Because of solar variation through the day, you will need a diode to keep the battery from feeding back to the panel when the sun is dim, and maybe a charge controller to keep the panel voltage from being excessive when the sun is bright.

By comparing the amps output from the panel with the average amps usage from the battery, you can compute how many hours of sunlight needed to produce how many hours of battery usage. We don't as yet have any idea of these numbers, so that is about as much as I can say thus far.

Hi Shindvs,

First of all referring this question in this forum was not correct.Here most of the members are from western countries. How they can give information about prevailing price of such panel in India?. If you wanted any technical clarifications then you should have asked the question in this forum. Better you should contact local mfrs. here in India for the detailed offer. There are many such mfrs in India who could send you offer.

Good point. In a thriving commercial culture, there should be reputable providers that will help their customers to buy a matched set of components such as solar panels, batteries, and inverters. Not every system needs to be designed "from scratch."

Every once in a while widget off to a bad start. I did yesterday and hope the guy n question accepted my apology.

if you want to do the design work without a professional download a program like PVsyst (there is a free trial version). You then feed the program with the local meteo file which you will also find online.

once you have that done you feed the program with your system requirements (it directly let's you design a battery charging system). The program will then define for you how many Watt peak of solar power you need to install. Pass a request for a quote of that many Wp to your local dealer and see what he comes up with. If you are not familiar at all with photovoltaic you may want to consider asking for a complete quote including installation.

as a little exemplary explanation: supposing your battery is a 24V 100Ah as everybody suspects you can store at most 2.4kWh of energy. The next step would be to know how much of this you need to recharge on a daily basis. I suspect you won't have a flat battery every day, will you? Once you know your energy needs you need to find out how many Wp you need to install in order to produce that daily energy. (a Watt peak installed means that when perpendicular to the sun in full sunshine it will produce 1W. As this is rarely the case you need to convert Wp to kWh/day). The program will do it for you but you can do it by hand using data like this:

http://www.synergyenviron.com/tools/solar_insolation.asp?loc=Mumbai%2CMaharashtra%2CIndia

You see that on a correctly tilted plane you may get an average of about 6kWh/m2/day of solar radiation o a yearly average. You need to design the stystem to work through your July/august through as well though, which limits you to a bit less than 5kWh\m2Knowing how much your panel gets per square meter then tells you how much you need to install. A typical panel you may get would likely have 130-150Wp/m2 which represents 13-15% conversion efficiency respectively. So per square meter installed you will get about 0.62-0.75kWh/m2/day in July/August if correctly tilted, oriented southwards and shadow free.

you can do the math now for converting the square meters to Wp for your order or use the link I posted if you have an other orientation in mind.

I just want to make one more remark. If you truly want to cut the grid line, you will need to install the system in such a way that the full battery and solar assembly will start your engine not only on the average day but on every day of the year. That means, your battery/panel combination must be capable to fulfill your needs even on the worst combination of bad weather days in Juli/August in your case.

Hi

Sorry I am confused, may be 1 Amp for 100 houre. 100 A/h and not 100 Amp for 1 houre with out of voltage drop. Don't retired Youget very rusty.

I'm sure that the rust is superficial.

A note on battery capacities. The Ah rating is normally the C2 capacity.

C2 is the discharge current for which a nominal capacity is attributed. C2 means, that the reference discharge current, for defining the capacity, is half the stated Ah rating value.

In this example we have a battery declared to be 100Ah capacity.

As you correctly reasoned, it is unlikely to deliver 100A for 1 hour. The C2 rating of 100Ah means that it should deliver 50A for 2 hrs, which is still, 50x2, 100Ah.

If the OP desires, he should be able to determine what the real capacity of the battery would be with the working load if he searches the internet for that particular battery's discharge characteristics.

Iwould look up the newsletter This Week in Germany and see if they might have a story about their new invention for storing energy from solar panels,also usa people probably dont get the indian products line on ther webpages as easily as you might.i would look up solar panel products india.

A 200 watts panel should do. It will cost you about Rs.15000/

P.M.Ramakrishnan

Thank a Dear Ramakrishnan

Regards Vijay

Why do you thank him?

So far we still don't know the necessary design parameters to define a panel size. Unless you can tell us how often you have power failures and what consume you have the answer that a 200Wp panel will do is just a wild guess.

Because He quote the price in Indian currency

The price he quotes to you is what I know as wholesale prices. Now I am interested if you actually manage to get a single panel for such a price. Retail prices, especially for such small quantities, may be a lot more. Don't be surprised if it is double to fourfold of that. (I don't know how many intermediaries you usually have in the Indian market. In the European market it is a strategy of many factories to not sell directly to individuals. This permits the intermediary to make you an interesting deal on a turn key deal because they manage to get so much cheaper at the modules than you may.)

never really understood the motivation of the panel manufacturer for this business model.

You can further save some costs. Your Batteries are 2 nos12V70AH. So in series it is 24V75Ah and not 24V 100Ah.

What happens when there is no power cut ? How will you consume the energy?If there is power cut after sundown and battery is exhausted, you will charge it full next day? That is more than 1000Watts power requirement by solar power. You need to redefine your usage.

Just doing some trouble shooting for you.

Regardless of the operating voltage the energy budget remains the same.

The energy budget will determine the required autonomy ,the generating (harvesting) requirements and reticulation capacity.

Designing a system around the battery is flawed.

Form should follow function. The energy budget defines the function.

OP needs to produce an energy budget first.

What is the cost for a solar panel, 24 volt battery 100 amp. I am having a APC 750 watt sine wave inverter. It will charge battery from AC Power.

If I want to charge the battery from a solar panel, what will the cost of solar panel in the Indian market ?

Hello friend bit old thread but were you able to find the right cost of using solar power? I do have plans of adding these panels on my home roof so hope you will reply soon..
