Solar Cell Price Per Watt ? - An Unusual Report !
If you've come across this page because you are eager to get the details on the best solar cell price per Watt, get set to be "enlightened"! I will teach you a sophisticated but easy method to equip your house with as much electricity as you need and evenaget paid for it. Am i dreaming? Indulge me a little bit - take a moment to check this out.
What is the purpose of giving money to the electric company every month when it's easy to generate energy with a solar power system, easy to build, easy to install, and quick to provide benefits? Happily, there is no steep price tag; it was out of reach for many people once upon a time, but now it's become the economical way to go.
You might wonder how i know about this. I started out by doing what you're doing - surfing the web for the best solar cell price per Watt and it came to my attention that there are literally thousands of homeowners in the united states and around the globe who had already gotten set up with a simple device which gives them the power to turn sunshine into electricity in just a couple of days. A quick research on that reveals another amazing fact - this can be achieved at what i would call a bargain basement price that won't break the bank - in fact, your bank account will thank you! Now we can all enjoy the growth in the field of solar energy that enables us to capitalize on the sun's free power supply as sure as the sun will shine.
Maybe you've just heard about the best solar cell price per Watt, and want to learn more, but be sure to double-check the exciting facts about it - with this method, you will have an infinite free supply of electricity, and you don't have to be dependent on the electric company or any other corporate to dole out your required electricity. Another advantage is that a common practice is to even make money from the electric company in your region for all extra electricity that you produce. Here's one more important thing to consider - by generating your own energy you contribute your part to preserve our planet now and for centuries to come.

QUESTION:
What is the price of solar cell to charge 12V 6Amp battery?
From where i can purchase the solar cells? & i want to charge 4batteries of 12 volt batteries for my collage project i have limited fund please answer me as early as possible....-
ANSWER:
Well the speed with which you want to charge those batteries is a direct relationship to what size solar panels you need. Lot's will do the trick. However, the charge controller you use dictates the voltage limits.Here is how it works.
Sun --> Panel --> Charge Controller --> Battery
Sun: Varies by time of day....
SO
Panel output: Varies by time of day inclinations etc...
SO
Charge Controller is designed to take a range of voltage that is huge, and normalize it before it goes into the battery. They are pretty efficient, roughly 90%.
THEN
The battery is charged as fast as the electricity comes through, as a battery is a power tank. To make it easy to think about, it is just like a water tank with different rates of incoming water, and the varying amounts of time to fill it up.The math looks like this.
FIRST: Ohms law (physics)
Watts = Volts x Amps12 volt, 6ah batteries, and 1 day to charge em.
12v battery @ 6ah = 72watt hours of power in the battery.
If you have 4, and they are half way run down then that looks like this.
12v * 6ah * 4 batteries * 50% dead = 12*6*4*.5 = 144 watt hoursThis means you need to produce more than 144 watt hours to charge em up. You have to compensate for the inefficiencies of wires, the charge controller, and the battery, so figure 1.5 that or 216 watt hours to be safe. Go search this site for lots more on the subject: http://www.bdbatteries.com/
So now we calculate how many panels.
Where do you live?
WHY? It dictates how many hours of sun you will get in a day.
6 in the desert southwest, 3-4 in the northeast.

http://www.bdbatteries.com/solmaps.phpFinally we divide the total power we need, by the number of hours we have to make it. This decides the array size. At that point we start hunting for panels.
So for our we will use Denver, and an average 5 hours of sun.
Math for the example:
216 watts/ 5 hours of sun = 43.2 watt solar array.
So 1 50 watt solar panel from some manus would do it.
I would get a 60 watt, as we rate panels at .80% for calculations due to real world.Click here for available solar panels. Concentrate on a cost per watt on the panel. This site even does the math for you.

But basically you are looking at 0-00 for a good one.

QUESTION:
Where can I buy a solar cell and a volt meter that is able to attach to it?
i am doing a science fair project involving solar cells, but i dont know where i can buy one, and i also need a volt meter that can be attached to the solar cell
preferably online and price is not a problem
thank you-
ANSWER:
I know you stated online but you should be able to find a voltmeter in many locations... Radio Shack and any hardware store with an electrical section should have voltmeters. Radio Shack will have Solar cells too but for a cheap source, check your local dollar store for a solar powered calculators.If you want to stick to online - radioshack.com - should have everything you need.

QUESTION:
where to buy a pre wired solar cell for use in a science fair project?
where can i buy a pre wired solar cell or pre wired solar cell kit that is reasonably priced and can be used in a science fair project?-
ANSWER:
try "Edmund's scientific"google solar cells
"Heartland" has one for sale bout
be sure you size it correctly. PS It will not work at night

QUESTION:
Project - High school - Solar cell driven battery charger?
Hey, so we're having a course called projectwork where we get to choose our own subject to research and write a report about. I choose to research about solar cells and try to build my own version of a battery charger driven by solar cells. Now though, I have just a few weeks left before I have to hand in my final report and I have postponed my projectwork alot. I certainly have no time to build this device, so I have to write about the theoretical part.My problem is, I have no idea what to write to make them pages look many. I will write an introduction, some information about solar cells, how they work more ingoing, some history regarding solar cells. I will compare solar cells in price, quality and how they might fit to the device. And I'm not sure how I'm going to present my idea in the report.
Give some tips about how I can fill out my final report please.
Thanks!-
ANSWER:
A key point to consider in summing up is the cost, covering the break even point for replacing an existing mains charger and in comparison with purchasing an alternative mains charger.Another issue to keep track of is usability, what if you are not in a sun facing room. Even in ideal conditions, how long will charging take.
Two possible conclusions to try to substantiate:
1. Solar charging is economical and practical unless you have a permanently shaded location.
2. Solar charging is slow expensive, unwieldy and a last resort unless you are unable to access a source of mains power or a 12v in-car charger.

QUESTION:
How much power does a solar cell collect per square foot?
I'm just asking regarding ordinary solar cells/panels, not anything new, special or over-priced. See, I have this idea, but I want to make sure they produce enough to actually accomplish something. I want to know:
1. Amps
2. Watts
3. Volts
I'm not very electricly-minded, so I always forget which of those does what. But this is just so I can run a few numbers. Thanks in advance.-
ANSWER:
That depends on different factor s
Manufacturer the max efficiency of solar cell is not more than 20% under ideal conditions
The temperature plays a big roll in the efficiency.
Angle of the light on the solar cell panel.
The time of the year because the son is not at the same distance from earth at all times.
Power in watt = currant (amps)*volts cos ф
Usually a solar cell is low voltage 12volte or 24 Volte
One very important thing that with solar cells you can accomplish nothing its so expensive that you will get your capital back after 20 years a 50 watt panel cost around 1000 $ do the math.
