Q:What solar panels are the most efficient?
About 20-22 percent is about right for panels affordable by most consumers. Even then, you still only get enough power to light a couple of lights for $400-$500, and only works when the sun is shining.
Q:solar panels vs (organic) plants?
Of course solar panels
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 to mount solar panel to car.?
In whichever car I'm not using much, I plug in a small solar panel to the cigar lighter socket, and simply place it up on the dashboard. So long as it gets daylight, it's working, it doesn't need full, direct sun. I just slip it between the transmission-tunnel and passenger seat when I get in, and my cars start right on the first turn of the key. It only delivers a very low level of charge, but it's STILL a net-gain, rather than the battery slowly getting a little tired - even the clock in the car, and the armed alarm-system takes SOME current to run, but even the smallest of panels will sort this out for you.
Q:Reflectors or mirrors around the solar panels.......?
In the 70's when silicon was really expensive, they played with using fresnel lenses to focus the sunlight on small solar cells but these panels had to be on heliostats and aimed directly at the Sun. These days, with nano-technology, there's a renewed interest in the concept but the fundamental weakness is that there are diminishing returns, at some point, it's just less expensive to have more solar cells.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
Q:How tangible do horseshoe solar panels sound?
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:solar panel regulator?
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:Solar Panel - Cell Resources and Calculations?
The two wiki links below provide basic explanations that are good starters. They also lead to other information. You do not mention much about the actual project, so I can only guess what level to pitch the answer. In practical situations you will not be able to work out Solar panel performance by a formula, but by looking up the manufacturer's specification (data sheet). From that you have the power in watts that can be drawn from the panel for standard sun which is taken as 000W/m^2 at a standard temperature, usually 25C. Derate the panel for the temperature when it operates in the sun (50-60C).
Q:Cars with Solar Panels?
How would a car with Solar Panels work in a city like London, Seattle, or Dublin, where it is cloudy and rainy more often than not? Unless there is a way to store up the solar power, I don't see it working very well.
