Q:Can A Home Owned Solar Panel Support The Entire House's Electrical Needs?
Solar okorder.com
Q:Need help with building a project involving solar panels?
Solar panels are designed to be used to recharge a battery or series of batteries, not for direct power. That is the inherent weakness of solar systems. The only way to have it work in low light conditions if to have several cells wired in series and have a voltage regulator to limit the amount of voltage that can be supplied. Other than that, add a battery and a charging circuit that the cell would supply power to.
Q:What solar panels are the most efficient?
New rollable panels are becoming available that don't have to be permanently attached to a surface and that are more resistant to damage than conventional panels. Right now they are also even less efficient than photo cells at about 0%, but the cost factor may make up the difference. Solar thermal is more efficient than photovoltaic cells. They focus sunlight with mirrors onto a pipe containing a liquid which is then heated to it's boiling point. That turns a turbine to produce power or is harnessed in some other way. The panels are cheap compared to photo cells, don't require perfect manufacture or exotic materials, no expensive maintenance and they are much easier to repair. I don't know of any available to individuals yet but there are at least two companies building generating plants in Nevada with this technology. SunPower is about 22% efficient but even at that rate it will take decades to pay for itself and the panels are unlikely to last that long at anything near optimal efficiency. The cost is just too high at present but solar thermal may provide a good alternative until photovoltaic cells mature, if you can cobble together a system. The final link is about a claimed 80% efficient solar cell that even generates some power at night. It's based on nano-technology, like many promising energy developments in batteries, electrolysis and ethanol production. If it works as advertised it should revolutionize solar tech. Eventually.
Q:How do Solar Panels Work?
Solar okorder.com/
Q:How many solar panels do we need to power the US?
Annual power consumption in the US is approximately .2*0^5 Watt-hours. The average solar panel can generate 80W continuously. We can break up the calculation into parts: .2*0^5 Watt-hours per year 925 hours per year .3*0^ continuous watts 80W per panel 64383566 panels 000 sq. inches average solar panel area 650 million square miles (!!!) To give you a better idea, the total surfacre area of the United States of America is 3 million square miles. The surface of the earth is 96 million square miles. Not even 3 planets full of solar panels would be enough. Maybe it is easier for people to start using electricity more responsibly?
Q:there can i get dc solar panels for out side lights?
They make lights that have solar panels built into them. Due to the solar cell, they can sense when it gets dark and thus switch on the light automatically. Look at Northern Tool or Harbor Freight web sites for ideas.
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:Solar panel questions...?
anythign can be scratched/ruined/altered if not tended to properly.... remove the first biggest layer of snow and leave a lil under to try to see first if it melts away on its own (dpeendin what season of course) if not than get some luke warm water and soak the snow.... slosh it off with a rubber shovel or mop.broom whatever wont damage ur panels. anythign you take care of will last longer and take care of you.... and solar is expensive to put in and can be expensive to maintain . depends where you have most sun and depends how many resources you use, if you leave the tv on absent mindely all night and take 50 min showers or blast the heat with jsut on epathetic lil donwpour of rain instead of just BUNDLING UP like a alot of lazy *** ameicans and.or rich careless bastards of course youa re goign to be paying up and out of your asshhhhh-hooooo and nooooo there are some different materials solar panels are made of, there is a main base/core they use but im sure there are AT MOST two...the rest is either glass or plastic! depends for what you want and how many , includign size.... good luck!!!! excuse my typos
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:what kind of rays are used in solar panels?
Electromagnetic...meaning light rays, primarily in the visible spectrum. Ultraviolet and infrared light rays actually degrade most types of solar panels, limiting their useful lifetime. That said, your question is not stated well...so I'm not sure if that's the information you were looking for. Rays are not used in solar panels...rather solar panels are used to collect sunlight and convert it to energy--either directly into heat in the case of passive solar, or into electricity by the use of photovoltaic cells.
