Q:Solar Panels and a Car Headlight?
It should illuminate two auto headlights on a sunny day, if it really generates 50 watts at 2 V. On a cloudy day, I don't know. It depends on how cloudy it is.
Q:Solar panels IRS refunds?
Not a good answer: CNBC had a news bit, that it can take 0 to 20 years for you to break even in energy costs after installing solar panels. Please don't buy them just for the tax deduction. See if you can google a calculator for this - do research. I have a brother in law that buys anything under the sun just because he gets a tax deduction. I'm sure you're not like that though. Run the numbers of what you will save vs the 2K you will spend You may never break even
Q:How to amplify current from a solar panel?
The previous answer about wattage is correct, so this is your first problem. Try increasing the number of solar panels by connecting them in parallel. To answer your question about increasing current, a voltage regulator wastes energy to regulate voltage. You need somthing that is not so wasteful, and that is a DC-DC converter. You will need to buy a 20V-5V model. this will give you less voltage but more current than you origionally had with your solar panel. You can alter voltage and current capacity, but you cant increase power (watts) with a DC-DC converter.
Q:How does a solar panel charge controller work for batteries?
In digital circuitry almst anything is viable. Virtually. The changing of voltages and currents is most of the time viable however not constantly effective. Sure it is extremely easy to make use of the 24 volt energy panel to charge a 2V financial institution, offered that the 24 volt supply has the fundamental current potential to hande the load.
Q:Question about using solar panels......?
I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
Q:Shouldn't 0bama increase our tax benefits for solar panels so we can buy more Chinese products?
Go ahead admit it...Carter was right ! He was right in seeking to raise the fleet auto mileage standard to 48 miles per gallon by 995. (Even U.S. automakers admitted at the time that they could easily achieve 30 mpg by 985.) Carter was right in exhorting Americans to turn down their thermostats, even if he did look nerdy in a cardigan while urging us to do so. He was right to encourage fuel conservation by proposing a 50-cents-per-gallon tax on gasoline and a fee on imported oil —- in effect, a floor for fuel prices. Invoking the pioneering spirit of the 960s moon mission, he was right to recommend a tax on windfall oil profits to finance a crash program to develop affordable synthetic fuels. Carter was correct, too, in setting a goal of obtaining 20 percent of our energy from solar power by the year 2000. The solar panels Carter put up on the Whitehouse were USA made. The solar
Q:Solar Panel Help? Beginners?
The okorder.com/... All the other sites you google/yahoo for will be advertisements. I think the author of this one was a engineering student. Hope this helps!
Q:Do solar panels effect birds and/or other animals?
No, they don't solar panels are harm less to the enviroment. They take in light energy, nothing else. So you don't have to worry about injury!
Q:solar panel regulator?
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:Where to get solar panels in Birmingham, AL?
Any electrical contractor could likely install them, and there are several Internet businesses that sell solar panels. You likely have no place there to get the kind of large panels you need for a house. Look at your local regulations. Your utility may not allow grid-tie, so you may have to set up an off-grid system with batteries and use separate wiring or a transfer switch. One thing a lot of people neglect is hail protection. In Birmingham, you're likely to have large hail (larger than golf ball size) every couple of years in the spring. You need to work out a way of covering them in advance of severe weather. Most panels will take up to golf-ball size hail with no problem. DK PS, I've done this myself, and have considerably more information. Email if you're interested.
