Q:Composition and function of solar panels
The demand for polysilicon is mainly from semiconductors and solar cells. According to the different requirements of purity, divided into electronic and solar level.
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:any one know about electricity solar panels?
The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .
Q:Why are solar panels grid-like?
They are in form of panels ....panel observe heat to generate electricity
Q:I will like set up a solar panel to cut down my eletricity cost in Cameroon.can you allocate me a supplier?
good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
Q:what is solar panel? full description needed?
Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.
Q:Does infrared radition occur in solar panels?
Solar panels do heat up. But that's because the radiant energy from the Sun that lies within the infrared (IR) band of energy causes the material in the panels to heat up. And that's the same for any body that has the Sun shine on it. Your face, for example, will heat up while you get a nice tan on the beach. That's due to the heat producing IR radiant energy. Now if those solar panels are supposed to heat buildings etc., that heat produced in the panels when the IR strikes them will be transferred, usually by some fluid, to floors of the rooms to be heated. And as the amount of heat generated by the Sun is proportional to the area of the solar panels, bigger areas of panel will generate more heat than smaller areas. Photoelectric solar panels are another kind. Here the interest is in the visible band of radiant energy from the Sun. Heat, from IR, is still there, but it is not the product sought by PE solar panels. The visible light photons knock off loosely bound electrons from the photoelectric material (typically silicon based) and those electrons are siphoned off as current. That's where the electrical power comes from for buildings using PE solar panels to provide their own electricity.
Q:Where are solar panels used?
This Site Might Help You. RE: Where are solar panels used? Where in the world are solar panels used. If it is used widespread across a continent just say which continent, other than that, just name the country. So where are solar panels used often?
Q:making your own and installing solar panels. Bull s*** or not?
In my opinion, it is a losing equation. They will wear out and go bad long before you break even with your investment. The technology isn't there yet for the average homeowner. Save energy costs using other methods.
