Solar Cells How To

We wondering where we could get solar cells for home use. we looked at helio's site, and was wondering if anyone else knew of any other places to get them, and have them installed. just wanted to know about cost and how it could help our $700...

Check out www.sunwize.com . They have hundreds of dealers that will install all over the USA. They have a very large warehouse in CA and NY and their prices are the same as everyone elses. I know this because I have a dealership with them.

The cable charger brick thing says 100-240v 50-60hz 1.5A input.The output is 19v and 3.95A
I was planning on using the solar cells out of the outside lamps that line the walkways ot houses.

well that might get expensive. see you have solar power, which is direct current (dc) power that needs to be converted into alternating current (ac) power then back to dc power. so you will have to have power inverters and monitors and all that stuff

I can imagine how to measure output power of solar cells. Then, how can I measure power of input-light? However I turn on 100V lighting, a half of power runs away as temperature. And all power of light can not reach solar cells because of...

You need to know the amount of energy available to the surface of the solar cell. This can be measured or estimated. Here are several sites that talk about solar radiation. There are many others if you choose to look for them;

Hard homework problem I don't understand.

Above the Earth's atmosphere, we receive about 1400 W=m2 of energy from the Sun. If you could convert 100
per cent of this energy into usable electricity, how large a collecting area...

The energy received by 1 m² = 1400 watt
Energy required to be produced = 1 giga-watt = 1 x 10^12
The area reqd. = 1x10^12 / 1400 = 714285714 m²
.................. ....................... ...........= 714 .28 Km²

I used a solar power calculator on SharpUSA. And found that $50,000 worth of solar cells would save only $500 per year in costs. Is it possible to sell these kinds of new technologies? That would take 35 years to payback. With the economy about to...

I have only $5000 in to my solar set up O but then I installed and have done all the up keep my self I use 12 volt DC and 120 ac. I spend $300 to $500 a year with add on's. It has been paying for it self..
I am not off the grid but I...

I am wondering, how many kilowatt hours per year would one square foot of solar cells produce if there were 2732 hours of sunlight per year, equal to 7.5 hours per day?

What efficiency? What angle? What latitude? What environment- hot, cold, clear, hazy, damp, dry,...? Stationary, single or dual axle tracking? How efficient are the inverters used?

Talk to a local solar installer- they...
