Q: How do solar panel power systems work?: Solar power works by making solar cells of two kinds of glass; one which has been “doped” to have too many electrons, and the other which has been “doped” to have too few electrons. These layers of glass are then glued together with a thin insulation layer in between them. The top layer of glass is the one with too many electrons, the bottom layer of glass has too few electrons, and the insulation allows electrons to pass from the bottom layer to the top layer easily, but not from the top layer to the bottom layer as easily. As photons come flying into this glass sandwich at the speed of light, the photons crash into the electrons in both layers and cause them to start moving. The electrons in the top layer are tightly packed and can’t move much, but the electrons in the bottom layer can move around enough that they end up crossing through the insulation into the top layer. However, because there are already too many electrons in the top layer, the newly arrived electrons have no place to rest. This buildup of electrons creates an “electrical pressure”. Then contacts are glued to the glass top and bottom, and a wire is added to connect the top layer to the bottom, and the electrical pressure which has built up in the top layer now has a way to escape, and the extra electrons which crossed over the bottom to the top can now return to the bottom layer. This flow of electrons from the top layer to the bottom layer is the electricity generated by the solar cell. A solar “panel” is made up of many of these cells wired in series to increase the voltage to make it high enough to do some useful work, such as charging batteries, and many of these panels can be wired together to do such things as supplying power to a building, or even supplying power to the utility grid.

Q: I had an idea for new parabolic solar panels shaped like horseshoes. They can install them outside buildings facing the equator. They could angle them from the ground based on how many degrees latitude the location and rotate them according to seasonal changes. The disadvantage of photovoltaic panels is that they are not all capable of receiving direct sunlight. That is the quintessential reason I believe horseshoe solar panels are more effective than flat rectangular ones. One side could function in the morning; the middle could perform at midday; and the other could operate during the evening. That method seems more sensible than hourly positioning. I'm certain horseshoe panels could save and produce more electricity. A football stadium, shopping mall, or outlet center would be a fantastic place. What do you think?: Sorry to be a prophet of doom again but the fault in the system is that only a small portion of the cell is used at any time of the day, given the high cost of solar panels this is not financially viable. Why not just have a small motor to turn the panel to face the sun, that's been done and it works.

Q: Can solar panels be installed on schools or universities?: Yes, solar panels can definitely be installed on schools or universities. In fact, many educational institutions are taking advantage of solar energy to reduce their carbon footprint and save on energy costs. Solar panels can be easily installed on rooftops or open spaces within the campus, providing clean and renewable energy for various electrical needs of the school or university.

Q: I want to get solar panels but not spend 20,000!! I found out that you can get a panel to run only your AC unit, I also found something that will run my pool pump! Anyone own either of these? How did you do? Where did you go? How much was it, and was it hard to install?: Most major cities have construction signs and other public things powered by solar panels. We have parking meter stands, USGS meters, street lights, etc. when these lose efficiency, they need to be replaced. They still work at about 60 percent efficiency. Learn who services these items and ask how to get them at a reduced rate or even for free. Be personable and nice and go to the source physically, not via e-mail. You can get a solar panel to run just about anything

Q: Can any body tell me how much Electricity can 0 Standard solar panels produce in a day( in terms of Watts)Or else please tell me how many Watts is 5 volts of electricity?: You have to know the amperage to figure out the watts. Volts x Amps= watts

Q: I have an electric bicycle that I travel to work by, pulling a modified child carrying trailer that holds two 2 volt deep cycle batteries in series to power the 24 volt bike motor. I'm thinking about adding a 50 watt solar panel (or larger depending on the room I can make available) to charge while I'm at work and to provide some extra juice while on my more distant travels.Can I get a solar panel to charge them while they're connected the way they are: in series? Does charging work that way?I've read that in order to charge the 24 volt battery setup (if the answer to the Q above is yes), the output from my solar panel would need to be a little more than 24 volts. Is this true? If so, how many volts?Since the bike is supposed to be powered at 24 volts and I have an x-volt (x gt; 24v) solar panel connected to it, will this cause any damage to the controller or other components while running them?Will it help supply power even while the motor is being run?Thanks.: Charging voltage = 2*3.8 = 27.6V Current regulated to AH rating divided by 0 Charging time = 0 hours

Q: hi, i got a pond and i am planning of putting some lights on it during night time. but i want to use solar panels and i have done a bit of research about solar panels and i know how they work, i know that the common voltage to use is 2v so you can use car batteries or deep cycle batteries, but my question is:. what wattage of bulb can you recommend2. how long it would take to drain my battery (can i have it overnight)3. and what wattage of solar panel should i get enough to recharge my battery the next day.hope anyone can help..thanks: You can get 6V cells and SLA batteries. You would get a panel and batteries suitable for the lights you get though. Depending on what you want to do, you shoud look into LED lighting, which is more efficient than incandescent. You do not want to drain your battery flat. Rather you want to draw only 2/3 of its capacity of so. You would find the lights you want (likely 2VDC), and add up the current they draw, and get a battery that would supply enough capacity (in AH, which is amps time hours) for a couple nights use (to account for weak solar days), and a solar panel to charge two days of use in one good day. You would use a charge controller so that the solar panel does not over charge the battery, and some sort of dusk timer to turn your lights on at dusk and off several hours later.

Q: I have four power packs for solar lights. They have 3 AA .2volt batteries of 2450 mAh capacity installed in series for a total supply voltage of 4 volt maximum for the lights. I want to charge all four packs at once off a single 6 volt solar panel. With the four packs wired in parallel, what capacity output (wattage) panel do I need to charge the batteries in an 8 hour day?: WIRE THEM IN PARALLEL BUT MUST VIA ONE BLOCKING DIOED FOR EACH 4V BATTERY BANK ( LIGHT) BETWEEN SOLAR PANEL OUTPUT TO EACH BATTERY BANK. DIODE USES LIKE N5404 THAT CAN HANDLE 3A OR HIGHER IS BETTER. TOTAL AH = 9.8 AH FROM ALL 4 LIGHTS. NOT 25AH FROM YOUR MISTAKE RATE. TO CHARGE THEM FULLY IN 8 HOURS, CHARGING CURRENT AT LEAST .3A BUY SOLAR PANEL HAS OUTPUT 6V 2A ( OR 0W ) IS GOOD ENOUGH.

Q: With no moving parts, no fuel piping and so on...: The only way I know of is to invest the money in the stock market. Most savings accounts only pay 3% intrest. While stocks float and if you don't know what you are doing you will never make as much money as you could save on your electric bill. Then the fact that you have to pay the electric bill out of the money. In the end you rented electric and can never get your money back. You can always sell the solar electric system and get your money back plus a profit. Not many people live in the same house even 20 years so it will sell. Toss the coin. It is what ever is best for you.

Q: i just took a trip to florida, they are cutting down anything that doesnt float and putting up buildings. Most of these cost a bundle, bill gates may pay cash for them, but most people will have many payments. Since pools, satellite dishes, and docks if near the water seem to be standard issue, why not a couple solar panels and water heater. It is florida after all, and if you are allready paying a half million or so for a house, what is another 0k gonna mean to you. Why dont they make it mandatory to include these on all new housing and condos and businesses. With that many the price would come down quickly and pay for itself long before the house is payed off and/or florida is flooded due to global warming.: Because not only does that just make TOO much sense, it comes down a cost factor, even though, as you say, what's another couple K for saving the environment. Sad thing is, even though they *JUST* figured out that global warming (loved that news story a couple weeks ago) is caused by humans abusing the earth, Americans especially just don't care enough. Our culture is so spoiled now that we refuse to be told what we need if it's not what we want or if it will cost us $5 extra.
