Q:Question about using solar panels?
If okorder.com and they ship across the US and Canada.
Q:How does solar panel help/affect the economy?
it would to reduce reliance on other sources of energy as solar is harnessed. It creates jobs for engineers and technicians. It has high initial cots, but is cheaper and stable in the long-run. Thus cost of production fall, AS curve shift downwards. Unemployment rate would fall as jobs are created. C rise. I rise.
Q:The effect of colored light on a solar panel?
It is based on what the solar panel is made out of. Many of them will generate electric into the NIR region.
Q:The future of solar panels?
Solar Panel really isn't any new technology, it was discovered in the early 60s. And as you can see it hasn't progressed all that much. But Developers are saying that within the next five years solar technology will increase dramatically. With more and more people looking for greener and easier forms of energy, there are many looking towards solar. In fact some energy companies are willing to buy the energy that you produce from you. And with new forms of thinner silicon panels, we are looking at a more efficient kind of panels. Unfortunately for us, at the moment thin-film panel silicon isn't as efficient as we are looking for. They are flimsier than the traditional panels and do not contain as much silicon to produce the electricity. But as soon as the demand increases, the production will increase, and if more companies are looking to invest in solar, then there will be more competition, with more competition- we are going to have improved technology, and with more improved technology, the prices will go down. Because at the moment, there is not much of an incentive for solar power. Compared to the Kilowatt- hour produced from coal and other forms of energy, solar does not produce as much. Experts are saying that within the next five years, not having solar panels on your house will be as silly as building a house without plumbing. The future on solar panels looks bright.
Q:How does solar panels work?
Solar panels are built with light-sensitive panels. These panels soak up the energy from the sun's light. This energy is changed to electric power. This power is stored in batteries to use whenever / wherever it is needed.
Q:What is a disadvantage of a solar panel?
They are costly, although technology is improving. To generate enough current to be useful, the panel needs to be large quite large. The sun tracks at different angles depending on the season and the solar panel would need to be repositioned to get maximum current generation because of this.
Q:solar panel, dc light help?
3 w for 2 hours/night is 36 watt hours. You'll get about 500 watt hours/day from your panel on the average, which for a 2 volt battery is about 40 ampere hours. You can get an 80 amp-hour sealed gel cell battery to charge with this panel (with a suitable charge controller). You want to size your lights so the battery can provide three days of light without discharging it more than 50%, so that's abnout 600 watt-hours/3/36 = about 4 orf 5 lights. Cost for this system woulkd be over $500. The advantage of the self contained light is they use a lithium or nickel battery rather than a lead acid, so it can run totally dead without damage (unmlike a sealed lead-acid battery). That would be a far cheaper way to go. DK
Q:What can a watt solar panel power?
You can run a lot of things. If you set the system to charge batteries when you are not using anything, they will charge effectively. You can use the system for lighting, LED lighting direct from the battery power is most effient since LEDs are low voltage devices with a very long life span. I replaced a 2 tube flourescent trough with four 5Watt PowerLEDs for example, While I have it on 20VAC at the moment, I can move it to 2 VDC power with ease, and had set it up to run initially on 2 volt sources. There are also many 2 volt appliances as well. You can even convert some of those all in one stereo systems to operate on 2 volts by eliminating the power supply. You will actually use less power by doing so. You will not be able to blow the shingles off the roof unless you add a Class D amplifier to the output, but for most listening, the output is adequate. Some small TV's these days can be run from 2 volt sources, if not directly, then with a buckboost inverter for a laptop. The small TVs only draw about 30 to 45 Watts. Skip the idea of using an inverter, they are not efficient at small loads, and represent additional load on the system. So with a little bit of planning, you can run a lot from that 60 Watt system. You can at least take some bite out of the electric bill for mundane lighting. You can also use them to keep power up on a battery system for lighting in a remote barn. The uses are only limited by your imagination and creativity.
Q:how much do solar panels cost?
The silicon ones(last 5 to 25 years) run about $4-$5 a watt the amorphous (thin film) a little less (may last 5-0 years). If you use megawatt hour (000 kilowatt hr) a month you will need at least 3000 watts minimum. Therefore if your electric is .0 per kilowatt hr( $00 per month) the payback is around 25 years once you add the batteries plus inverters(batteries $50-$00 each)(synchronous inverter $3000 to$20000)(ie $5.00/.0=50 months at optimum output).Figure (depending where you live) probably only 50% so break even is usualy about 20 yrs.Ie you pay 20 years electric bill and hope nothing breaks(insurance not included) then you can start saveing money.
Q:cost of solar panels?
It all depends on where you live and who you get them installed by.
