Q:its about solar panels?
If solar power is not practical, why do four of my friends and I have it? Actually Don M is mostly right. The factors to consider when contemplating a solar installation are numerous. For example my system will not pay for itself in utility savings in my lifetime, but I plan to sell the house soon. What I am saving on electricity costs, and the increased amount I can ask a buyer, I will come out well ahead. Cruise the Internet and look in the green search box at the top of this page, for solar panels. As you learn more, you can come back with more questions.
Q:Questions about solar panels?
I can begin to point you in the right direction. It is a very complicated thing you are asking about. Solar panels produce direct current, in order to store that power for use at night, and on cloudy days, you need a lot of batteries. Those batteries store direct current. In order to use that direct current to power your refrigerator, you need to put it through a thing called an inverter. The inverter produces AC from DC. You may have seen one for sale to plug into the lighter in a car so you can use things that require AC in your car. The inverter looses power doing the conversion. Over time, you can purchase direct current appliances, and make the system more efficient. Years ago, a decision was made to go with AC because of transmission issues (you can move AC across a wire a long distance, and DC is more difficult to move). Many appliances convert AC to DC internally to do their work, but such appliances are expensive. Have I answered your question? Not really. You should understand your question better though.
Q:can a small solar panel be charged with lamps?
yes, although charged is the wrong term. But for every 00 watts you put into the lamps, you will get well less than 0 watts out of the solar array. Well less. .
Q:Has anyone gotten their solar panel rebates in Florida?
In case you hadn't heard the state is broke.
Q:what do solar panels do?
The cost of electricity is increasing at a rate of 5 to 0 percent every year with no end in sight. A solar panel system captures the (free!) sun and turns it into usable electricity for your home.
Q:How does a solar panel turn sunlight into electricity?
my theory is that when sunlight hits the panel it excites the electrons from the rays there by making them move more quckly and attract them to a source with less elctrons making the panel positiveli charge and the electron collector negatively charged thereby connecting the negatively charged particles to which ever body it wishes to donate it too thereby causing electric charges
Q:How many solar panels have ah?
Classification of solar cells: Currently on the market of solar cells into amorphous silicon and crystalline silicon. Crystalline silicon can be divided into polysilicon and monocrystalline silicon. From the photoelectric conversion efficiency of the three materials is: monocrystalline silicon (up to 17%)> polysilicon (12 ~ 15%)> amorphous silicon (about 5%).
Q:How to prevent shorting out solar panel?
A solar panel doesn't store energy. As soon as the light stops, the current stops instantly. If it's a 200-watt panel or more, it won't be harmed by a short circuit, but it might be good to turn the panel over or cover it with cardboard before working on it. The spark can slightly mar the contacts. Doing the work indoors is enough to cut down the current, too. For a 60-watt panel or less, I wouldn't even worry about the spark, the power output is too low to do any damage.
Q:What should the voltage be on a small marine solar panel?
Mark, the 2 vdc is pretty typical. Most panels for home use are set up to charge 2 volt batteries, and they are wired for an, open circuit voltage of 8 to 9 volts. This allows it to have enough voltage to feed through a few diodes, perhaps a charge controller and 30 or 40 feet of wire and still have at least 5 volts left over. Once you connect it to the battery the panel will drop to whatever the batteries charging curve voltage would be. If you have a few minutes, I would suggest getting a book at the library called, The Complete Battery Book, by Richard Perez. Just read the chapters pertaining to lead acid batteries, the other discussions on lithium, ni cads and such won't apply to your boat system. If your panel is not large, and it's short circuit current rating in amps is less than 2% of the amp hour capacity of the battery, you can even run the panel without a charge controller. The book explains this as well. There is a great magazine that gets into the nuts and bolts of this stuff, it's called Home Power, you can find it online. You might also find some info at a couple renewable energy websites, I will list them below. Panels are rated in two ways, open circuit voltage, which you measure with a multimeter while the panel is in open sun and nothing is connected to it. The other rating is short cirucuit current, which you measure with an ammeter while the panel is in the sun as well. You connect the ammeter across the output of the panel and let all the power short right through the meter, so you'll need an ammeter big enough to handle more amps than the panel puts out. A 0 amp unit will work for your boat panel. These tests won't hurt the panel, or the meters, we do it all the time in the field, and the manufacturers will tell you to do the same test if you have a problem with a panel and they want to know if it's malfunctioning. You can check one of their websites if you like. Good luck Mark, and take care, Rudydoo
Q:Increase Solar Panel Efficiency?
There are 3 (simple) ways to increase the efficiency of a solar panel at home - they all work by increasing the amount of light that falls onto it: . Have the solar panel track the sun throughout the day so that it always faces it; 2. Place a lens (larger than the panel) in front of the panel that focuses the light from the sun onto it. 3. Have mirrors around the panel than redirect light from themselves onto the solar panel. (e.g. imagine a satellite dish with the solar panel at the front and the dish being all mirrored.)
