Q:Can someone tell me about solar panels for homes?
I had one on my homestead in CT. It grew to become right into a photograph voltaic warm water heater. It grew to become into hooked as much as my general warm water tank, so as that if it have been cloudy for a pair of days..i could nonetheless have warm water. in case you think of of all of the nice and comfortable water you employ, it grew to become right into a real mark downs. whilst i bought it, you purchased a $3000 tax credit from the government. that could be a protracted term investment , yet i could say mine paid for itself in 3 or 4 years. i could be careful presently..with oil being so costly, you going to have crooks and fly by utilizing nighttime businesses obtainable.make certain you examine out the corporation...very intently. And be taught , be taught, be taught...approximately how the structures paintings
Q:What are the government/commercial incentives/discounts that come for solar panels?
Go okorder.com/ and click on your particular state. In the US today, panels are a money saver, if that, but not a money maker. Don't expect to get rich installing panels. A right-sized system will save the most money; more panels are not necessarily better. The arrangement you describe sounds like grid-tied, net metered solar. Try getting a free quote from a professional installer to see what size system would be appropriate, and how much it would cost.
Q:what do we mean by efficiency of a solar panel?
Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.
Q:How efficient are the solar panels....?
DS's solar panels convert 22% of their available energy into electrical power. This may not sound very good, but it is much better than most solar panels. Most solar panels on people's houses, for example, are fairly inefficient. Less than 4% of the energy that reaches them will be converted to electricity. DS's panels are so efficient, in fact, that unless the ion propulsion drive is running, DS is producing far more power than it needs.
Q:How long does it typically take for solar panels to pay for themselves?
It's generally stated that it takes 0 years for them to pay for themselves. But the concept of paying for themselves is a primitive concept used by those who do not understand finances. You're still losing money when it pays for itself. A more appropriate analysis would be the Internal Rate of Return calculations, Excel makes this calculation easy. Overall, solar power is expensive power and works out about 38 cents per kwh ( proper economic estimates typically place it between 23 cents to 45 cents per kwh ). Some idiot here will insist solar doesn't cost that much per kwh, it does unless you're uneducated in finance. Note, it's also not clear if the energy produced by solar panels exceeds the energy required for their manufacture, delivery and installation. It takes a lot of energy to melt silicon and the costs triple if you try to recycle the toxic wastes which is why the panels are made where it's still possible to dispose of the toxic wastes. They could very well be causing more environmental damage then they save. With the Europeans what happens is the feed in tariffs makes the solar panels worthwhile. They still don't really pay for themselves but they allow you to take some of the tax money from your neighbors, a bit of an ethical dilemma really but ethics never stopped Europeans.
Q:kilowatt solar panel help?
Also you can look for INSOLATION TABLES on the Internet. Keep in mind, though, that the useful output of a solar system that produces AC will be somewhat less than the theoretical value. Local conditions, orientation of the modules, dust on modules, wire resistance losses and efficiency of inverters will drag down the true output. My 6 kW system produces just over 4 kW at optimum sun height.
Q:Best orientation for my solar panel?
Typically, solar panels are installed facing the same as your latitude = 2 degrees to the North measured from horizontal. 60 degrees from vertical = 30 degrees from horzontal will give almost as much power in June as in December = beginning of Summer. You can face your panels straight up = zero tilt from vertical = better for December/ not so good in June. Usually, the same tilt as your North facing roof is best as it simplifies installation and reduces wind loading. Shade from trees etc will much reduce the power you get. Neil
Q:Solar Panel Question...?
Nice enough idea you have there, but practical reality is waiting to bring you back to your senses. The appliances you want to operate take a lot of power. You would need an awful lot of solar cells or a very cumbersome windmill to provide sufficient energy for them. You will find that for a mobile kitchen, an ordinary generator running on gasoline or diesel will be much less expensive to buy and maintain, less trouble to haul around, and much easier to replace if necessary. Considering that propane will probably prove less expensive yet, go with that for as many appliances as possible.
Q:How to make 2V 4.5A solar panel from solar cells?
To increase current, you connect the cells in parallel. But I think you really mean you need 4.5 watts rather than 4.5 amps of current. For an RC car, 4.5 amps would be huge, literally a regular car battery. So I think you mean you need a 2v, 4.5w panel. That would make more sense for an RC car battery. I went on OKorder and bought a 2v, 5 watt panel for about $30.
