Solar Module Introduction

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.

Electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. The cells must be connected electrically to one another and to the rest of the system. Externally, popular terrestrial usage photovoltaic modules use MC3 (older) or MC4 connectors to facilitate easy weatherproof connections to the rest of the system.

Q:Please differentiate b/w mono & poly crystalline silicon solar panels.?
In the practical sense, the differences are trivial. I'd buy on price per watt, unless space is at a premium (it isn't for most installations).

Q:How may solar panels/wind turbines may be made affordable?
go okorder.com/ they sell books on how to build solar panels and wind turbines, along with a lot of other things that could help you live off grid. And a lot of the books were things that could be made with turn of the century (900 not 2000) technology
Q:Can You Choose Between Solar Panels And Aircraft Fuselage Report?
Solar Panels. Solar panels is a generic term for any semiconductor that converts solar energy to electrical energy. However there many different kinds of solar panels and constructed in different ways from different materials. There is the generic polysilicon solar panels for residential installation on one end of the spectrum. On the other end are very high efficiency (and expensive) solar cells used on the Mars Orbiter that are constructed of so called triple junction GaAs/Ge solar cells. In addition there are also the thin film solar cells that are being researched that use Cadmium Telluride (CdTe) to form junctions and make very efficient cells on very thin substrates. I would say that research into materials that can be used for solar cells is one of the hottest research fields right now. (That being said, I really did enjoy Airframe by Micheal Crithon. Whenever I'm in a plane during bad weather I always thing of the engineers that designed the plane... what assumptions did they make... what tradeoffs did they make... )
Q:Solar Panel Watts?? help!?
This is not a precise analogy, but think of it this way: Volts is the pressure of the water in a pipe. Amps is the gallons per minute that come out. Watts is how much water you have after a certain length of time the pipe is open. a 200 watt solar panel under ideal conditions ( bright daylight between , say 0 am and 2 pm, held exactly flat to the sun ) will produce enough energy to run 2 00 watt light bulbs. You hardly ever have perfect bright sunlight; the length of the day varies during the year, and the angle of the panel to the sun changes from hour to hour; all this leads to a typical home in the US /Europe having only about 4 hours a day of maximum solar available. So, your 200 watt panel would give you 800 watts a day, enough to run one 00 watt light bulb for 8 hours If you are trying to run a house off solar, there are unfortunately other things needed between the panels and the lights / appliances; inverters, batteries, controllers sand each one eats up a little energy so you may get only 75 useful watts. See why more homes don't have panels? The other poster who said $30-50,000 to completely run a home on panels is about right.
Q:What to do with a solar panel?
Hey AJ, Tom is quite right, a panel that size is a great trickle charger at .2 amps. If you have a good sized 2 volt battery, like from a truck, or for a boat trolling motor (it should be at least 60 amp hours) you can hook it to the battery and it will charge it slowly anytime the sun shines. Don't worry about the voltage, most 2 volt nominal volt panels are wired for 8 - 9 volts, and if you hook them to a battery, the panel voltage comes right down to the batteries charging curve voltage anyway, they are designed for that. What you do need is a diode. A diode is an electrical check valve, allowing current to flow in one direction, but not the other. This will prevent the battery from discharging through the panel at night. Many panels today come with diodes inside the junction box on the back of the panel. If yours does not have any, go to Radio Shack, look for a 6 amp silicone diode, usually around75 cents. Put it in series between the panel and the battery, then, while you have a voltmeter hooked to the battery, connect the panel/diode to the battery and see if the voltage goes up slightly. If it does, you're all set. If not, turn the diode around and try it again. It has to be connected into the circuit the correct direction. Many people will state that you need a charge controller, but this is not necessary if your panels max current, ISC is less than 2% of your batterys amp hour capacity. In your case, if you have a 60 AH or larger battery, skip the controller. There is a great discussion about this in Richard Perez's book, I will list it below. If you want to learn more about these devices, there is a great magazine that gets into the nuts and bolts of renewable energy, it's called Home Power Magazine, the link is below. We started by hooking a slightly larger panel to some golf cart batteries 2 years ago, reading that magazine and going to some energy fairs. Today our home is completely powered by the wind and sun. Check it out sometime. Take care, Rudydoo
Q:know about solar panels?
Solar Panels are groups of Solar Modules mounted together. A solar cell is one cell. A solar module is a group of cells mounted in to a sheet A solar panel is a group of solar modules connected together on a rack and normally placed on the roof etc.. as a unit and can be called a solar array. A solar array is a group of solar modules or solar panels all mounted and wired together to form a single unit. Like a battery bank is a bunch of batteries hooked together and the batteries are made of cells. Was that what you wanted to know?
Q:Photodiode vs solar panels?
Yes, so are camera sensors. Except in cameras they're specially desgined to reduce noise.
Q:Any tips for protecting my solar panel from high winds?
Solar panels are a costly and significant investment. Therefore, protecting them from harm should be a top priority. Unfortunately, moisture and water are common ways for solar panels to become damaged or broken. Safekeeping solar panels from both of these threats is a simple, inexpensive procedure, and doing so might save the solar panel owner a bundle if carried out correctly Instructions : Set a thick strip of silicone between each cell when putting the solar panel together, in order to prevent moisture seepage. 2: Use Plexiglas instead of glass as the face of your solar panel. Plexiglas is less liable to break and therefore safe from hailstorms or accidents. 3: Glue adhesive silicone to each side of your solar panel(s), adding additional sealant and protection from water to your commodity. :)
Q:I would like some info on Solar panels and Wind Generators...please?
Toronto would not be higth on my list of solar panel worthy locales. They are a bit pricey and are only cost effective in climates and locations with lots of direct sunlight. But if you could safely say you get direct light on your rood nearly every day, they could work. Wind turbines are getting better... especially omnidirectional dome type turbines. But again they are a bit costly, and work best if you believe you get direct wind for at least half the day. If your roof is reasonably flat and structurally sound, a solar hot water generator can be quite cost effective. Essentially it is a panel of corrugated metal under two thin transparencies of plastic. Water is pumped up to it and as it runs along the corrugation, the trapped heat under the plastic heats it up nicely. They are cheap to buy and easy to build and install, and will completely remove the need for a dedicated hot water heating system. Once again, it really depends on the precise location and construction of your house. Do a search for solar heat in your area. If it is cost effective, someone will be offering...
