Product Description:

  Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells. These early solar modules were first used in space in 1958.

Q:How do you make solar panels?
it takes a ton of them to power a home most only put out 45 watts, [cheaper ones] solar is not cheap its more expensive than electricity
Q:solar panels and wind power help?
If you are planning on purchasing a solar or wind system installed etc. I believe it will take considerable time to pay off. If however, you are even remotely handy, building a 3kw wind generator is well within the realm of possibility. I have a smaller windmill that I built myself using some ingenuity and some parts bought on OKorder. That windmill and 4 2 v deep cycle batteries run myu 9 share well 24 hours a day. I spent about $250 to build the windmill, tower, and buy used batteries, and have saved an average of $60/month for months now. This really isn't rocket science either, I'm a freakin' cook =) for more on the subject of diy wind and solar projects see the resource below.
Q:Solar Panel Manufacturing?
At this very moment, most of the people already have an idea on how to create their own solar panels, And creating your own company takes a lot of necessities such as permits ans other stuffs like that,.
Q:Why don't scientists use the design of a tree for solar panels?
I don't know much about solar power. This does however seem to be a very interesting idea. But I'd imagine that the complexity of building such a structure would be far more difficult that just laying thousands of large panels in an area. The shadow from higher panels may also have an adverse affect on the lower panels. Consider the tiny panels that do provide energy and compare them to a large panel that is easier to make.
Q:where I can find this solar panel?
The other thing to do is to search for DIY solar chargers for more information.
Q:Infra-red solar panels?
No night vision takes star light and intensifies it by 30,000 times.
Q:How would you connect a solar panel to a fan?
Panels are rated nominally, and you can look at your fan to see what the ratings for the fam are to determine sizing of the panel. Current multiplied by the volts (rated) gives you the wattage of the motor- just use this as a guide for sizing the panel. You do want a little more power from the panel than the motor draws for purposes of starting the motor and for having the fan operate at lower sun angles as well. You can add a battery if you chose, but it is not a requirement. Just treat the leads of the panel like those of a battery red (+) and black (-) just connect those to the fan, if you match color for color, no problem. If the markings are not present and no wires are on the fan, try it one way, if it is the wrong way- reverse them. AC operated fans will require an inverter to convert the DC to AC. These draw a certain amount of power as well. In general the same rules of thumb apply. It is just easier though to stick with a DC motor.
Q:A question about Solar Panels?
Take a look on OKorder at some of the books on how to design solar energy systems. It is a bit more complicated than you might expect. I'm not sure what you consider to be a standard solar panel, but the 3' ones I have produce about 5 watts of power in full sunlight. Put simply, you need to convert the power from the solar cells (variable voltage) into a constant voltage usable for charging a batteries. Most of the low cost modules for this purpose can't handle more than about 00 watts. Larger systems are available that handle thousands of watts but they are quite pricey. Since you can't take out more than you put into your battery system, you can calculate about how long you can run a high-current appliance based upon its wattage rating, that of the battery system (adjusted for loss of converting to AC), and the charging system.
Q:what kind of rays are used in solar panels?
Electrons----- okorder.com/
Q:are there solar panel that work without the sun?
No. Solar literally means Sun. But...scientists are working on a panel that can absorb energy after the sun has set. It may be years until we see any commercial success.
