Q:Solar Energy - What would these solar panels power?
note breath on the winds excellent answer is one quarter of one percent. See why houses aren't covered in solar panels? it's just not a real answer right now,. the rough rule of thumb is $0 per kWh ( for just the panels) you want to produce. You'd need $20,000 in panels and another 0,000 in controllers and inverters and batteries and who knows how much in installation.
Q:Does anyone know a good company to buy solar panels from?
Wow. This is a big question. First, are you in the United States? If so, then I would look at a couple of web sites. First, I would look at joining ASES - the American Solar Energy Society. (Actually, I'd do this whether or not you were in the US) Their magazine will have ads and directorys and so forth for panel manufacturers, inverter manufacturers, rack vendors, metering companies, etc. At the very least, their web site will give you numerous links to popular panel manufacturers. Right now, it can be difficult to get panels in the US. My buying agent can't promise us a significant number of panels until at least late this coming fall. And prices are going up due to a silicon shortage at the moment. Still, you could probably get your hands on small quantities. You just might not be able to choose exactly which manufacturer you want. Also, I'd look into getting NABCEP certification. This is the North American Board of Certified Energy Practitioners. They provide a referral service for people looking for solar installers, and they may have a net work of members that could help get you started. Good luck!
Q:Finding the output of a solar panel?
You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.
Q:Please differentiate b/w mono & poly crystalline silicon solar panels.?

Q:How to build solar panels?
You cannot build solar panels. I believe what you want to do is build a solar system for your house. If you have a background in electrical system you could do it yourself. Otherwise you would be ahead to have professionals install the system for you.
Q:H2 as an Alternative Fuel Source using Solar Panels?
It's an idea that will be done someday. But right now the problem is that there are much cheaper ways to get energy and run cars. So no one would use this one, because it just costs too much. As other sources of energy get costlier, and we figure out how to make solar panels better and more cheaply, this will be done. The best way known now to use the hydrogen in a car is to put it into a kind of electricity generator called a fuel cell. Then the electricity runs an electric motor. Controlling the measurements into the fuel cell is pretty easy just with a simple flow meter.
Q:How Do solar panels work?
Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
Q:solar panel installed house roof?
How does the cable wires stay on the solar panel? With wire retention clips (4 per module) that are used to wrap the wire on the underside of the module frame. The home run cables to the transition box (converts between types of wire with no electrical transformation occuring) or combiner box (joins multiple source circuits in parallel, with the positives fused for safety) are usually tied along the racking system components, and with conduit sections used as needed. Racking is another big part of the installation. Don't just make your own homemade wooden rack, as these will weather away to nothing very easily, and cause great failures. GET a professionally designed metal racking system. PV modules are EXPENSIVE. Don't let the racking system cause them to break. It also requires the inverter, if you intend it to connect to the main electric service. If using multiple inverters, you need an AC combining panelboard to join them prior to entering the main electric service. Otherwise, you need to think about how else you might be using them. If you are charging batteries, you need a charge controller.
Q:How do Solar Panels work?
Light consists of small packets of energy called photons. When photons with sufficient energy strike the photocell its energy is converted into electrical energy which is stored in the batteries as dc voltage. To run a TV an invertor is used which converts dc to ac. Now you can make a block diagram of it and present it TC
Q:Need Large solar panels. ?
I think you may be surprised how much energy a little cafe like that uses. Since the air conditioning, refrigerators, and other appliances are going nonstop, I'd expect the energy usage to be several times that of a normal house. If you have access to the electric bills of the cafe while it was in operation, look up the kWh's used per month. For scale, I will say that our house uses 500 kWh per month, and needs 3 kW of panels to keep up with that. Scale up to match the restaurant, as a ballpark estimate. If you don't have access to the electric bills, then go visit a similar cafe in town, or a nearby town, and ask them how much their electric bill is. If the ballpark estimate still looks doable to you, then contact a professional solar installer to get an accurate, no-obligation estimate. Most likely, the cafe will use gas heat for cooking. But if not, electricity from solar panels is probably the most inefficient way to cook. Consider having solar ovens for most of the cooking, if you have land, with gas as a backup on cloudy days.
