Q:environmental benefit of solar panels?
The social earnings is that with photograph voltaic panels they help decrease pollution that fouls the air that the ordinary public breath and it will supply up/decrease killing human beings for the supplies used now (oil gasoline) and likewise social is they gained't could dig in those risky mines for coal, which would be a social earnings. Economically it is going to pay off in the money sooner or later once you pay-off for installation them. Environmentally they help with removing pollution from the different supplies (coal, oil gasoline) additionally nuclear potential is barely stable for potential, yet commit it to memory remains turns right into a waste which will exchange right into a pollutant.
Q:How to build solar panels?

Q:Solar panels...??? HELP!?
All depends on how many watts you have. I ran a small boom box off a 5w panel before with no problem. The higher the wattage, the more you can run.
Q:What factors effect the amount of electricity produced from solar panels?
It depends on what you mean by amount of electricity. Normally that would mean the total energy produced over a given period. In that case, the main factors are ) Efficiency of the solar cells 2) Total irradiation received: incident radiation density times the solar panel area, and the angle of the incident radiation. Item ) is determined by the materials and method of construction of the solar cells Item 2) depends on the location of the panel, both on earth's surface (latitude), time of year, and how the panel is oriented with respect to the horizontal. Altitude of the location can also be a factor. Prevailing weather conditions, number of cloudy days, etc. are important. Independent of these parameters, larger area means more electricity.
Q:A question about solar panel?
I found some 0 square ft. solar panels that produce 30 watts . 3 watts per s.f. . A 2,000 s.f. home would consume around 2,000 kilowatt hours of electricity in summer months in areas that require air conditioning . This would require 67 kwh daily . You would need ,000 s.f. of panels and dozens of batteries to store the energy for night time .
Q:What does solar panel power?
I doubt it'd supply your heat. Anything involving electric heating uses tons of energy. Also, keep in mind that you don't just need a panel but also a DC to AC converter.
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:Is it truE thet solar panels. . ?
They can supply a current on their own, but that is not very useful. A battery allows you to store that current so that you can use it at night or when clouds are blocking the sun. the voltage regulator makes sure they do not provide more power than the battery or whatever else you hook it up to can handle. Most places that sell solar panels will have these items to go with them. You will probably want a battery with a larger capacity than a car battery.
Q:Solar Panel System at Harbor Freight?
i wouldn't. - harbor freight isn't known for the best quality stuff. - 75 watts assumes roof mounting, at 90 degrees to the sun, on a bright day. you're going to get considerably less. and only when the sun is highest in the sky. maybe you should look at, your computer, for example. if you're using it for 4 hours, and it has a 500 watt power supply, and you add 200-500 watts for the monitor, and some for the printer, modem, etc, you'd use 5kw that day. your 75 watt panel, generating maybe 50 watts at most, for maybe 4 hours when the sun was highest, and shining directly on the panel, would generate 200 watt hours. it would take 25 days to generate the electricity you'd use in single day. in the winter, you'd be pretty much out of luck. there just isn't enough bright sun. clearly, it's up to you, but there's a harbor freight near me, and i'll not be rushing out to get such a system. further, most appliances are quite voltage sensitive. you really do need to have the voltage in the 0-20 range. too much out, either higher or lower, will shorten the life of appliances at best.
Q:What is the principle of solar panels work?
light - heat - electric conversion method through the use of solar radiation generated by thermal energy, usually by the solar collector will absorb the heat into the refrigerant refrigerant, and then drive the turbine power generation. The previous process is the light-heat conversion process; the latter process is the thermo-electrical conversion process.
