- Q:Will a 2W, 2V mono solar panel power up a laptop battery?
- I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
- Q:With everyone thinking green...how green are solar panels?
- Most of the early panels were not very green. They were not very efficient and did not have a real long life span. The newer one are getting much better and there are several companies have cropped up that rebuild many different kinds of panels. Some of these newer panels have a life span in excess of 30 years and are much easier to maintain. The biggest problem with solar systems is that they are not kept clean and loose efficiency. If interested in setting up a system for your self, Please be very careful who you have do the work and what system you buy. There are many companies out there that are just trying to make a quick buck at your expense.
- Q:having problems with my homemade solar panel....?
- You description is not clear as to what is supplying and what is consuming the .2, 8, and 5. volts you mention. I get that your solar panel output is .2 VDC (volts DC), but is that open circuit or under load? Also, is the charger output AC or DC? What's using 8 volts? Circuits don't selectively use a portion of the voltage supplied. They use all or nothing. Is the polarity correct from your solar panel to your MP3 player? If your MP3 player requires DC for charging and you're feeding it the correct polarity, but too high a voltage, an overvoltage protection circuit in your MP3 charging circuit might be blocking the charging current from your solar panel. Go through everything again and if you need to post another question on YA, be specific as to what you're measuring, where, and whether it's the source or load you're measuring.
- Q:What should the voltage be on a small marine solar panel?
- It has to be facing the sun for full power U check at the battery and it should increase as the sun hits directly on it. U can't check it at the panel after the diode.
- Q:Are photovoltaics to do with solar panels?
- Solar panels are a generic term for any type of solar collecting panel. There are two major types: Photovoltaic uses substances that turn the incoming radiation directly into electricity. Usually you have to have direct sunlight (no clouds) for this to work well. Solar thermal is also used in a lot of areas. Here the radiation is used to heat a circulating fluid (often water directly), and then that is either used directly, or it's used for heat exchange with a heat pump or a boiler system. Solar thermal can collect significant heat even on a cloudy day. So a solar panel could be made of photovoltaic panels, but it doesn't have to be.
- Q:Can I join 5 or more solar panels into line to the battery bank. I don,t have a regulator connected, just st?
- You can do this, but it isn't the best way to go. There is no problem with joining the solar panels. There are two ways to do this, in series and in parallel. A series combination will add the voltages that each panel is producing together, but not the amperages. For example, if five panels are producing 6V at 300mA each, the end result will be 30V at 300mA for a series array. A parallel combination combines the amperages of all the panels, but not the voltages. So, in our earlier example, five panels at 6V and 300mA would provide 6V and 500mA (.5A) if wired in parallel. Series-parallel combinations are also possible, giving some of the benefits of each method. This would probably better understood by doing a quick search on Google Images for series, parallel, and series-parallel. You CAN connect the solar panels directly to your battery bank with no regulator. Unfortunately, without a regulator, the connection is two-way. When the sun is out and the solar panels are producing more voltage than the batteries, the batteries will charge. However, when the panels are producing less voltage than the batteries, the batteries will instead send power into the solar panels, which will be dissipated and wasted. The panels may charge your batteries during the day, but they will discharge them at night.
- Q:Life expectancy of LEDs and Solar panels...?
- ED stands for light emitting diode, an electronic device which turns electric power into light with nearly perfect efficiency. When used in flashlight or othe battery powered lights, they will provide equal amounts of light for 00 times as long as ordinary incandescent light bulbs. Because of there very low power usage, led light are ideal for solar powered lighting systems. They are now made in every form and size, for DC or AC power, for homes, automobiles and outdoor lighting. Although they cost more, the savings from 20 year life expectancy and % power use mean savings of 95% over several years. sunsourcepower

- Q:Amount of solar panels needed to run a/c and pool pump?
- Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
