Product description

A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.

Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

 the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q:How can I make a sun tracker for a solar panel?
Since the sun moves in the sky on a very predicatable course you don't need a closed loop control system to track it. All you need is a clock-drive motor and the proper gearing for your latitude. The clock drive motor will move at a constant rotational velocity based on time, and when it is geared down properly the angle of the shaft will follow the sun. Make sure the clock motor is powerful enough to move the solar panel, etc. That's a start, anyway. .
Q:How powerful are solar panels?
very hot it can attract the sun
Q:Solar panels and supplementing your AC power source.?
The okorder.com/
Q:solar panels on projectors?
Unlikely to prove useful. Solar panels don't generate very much current. You would probably wind up spending several thousand dollars, and wind up with a solar panel array (including batteries and power inverter) that is certainly not portable. You will also need adequate current for your projection source (ie DVD player or computer), as well as sound. By and large, the cheapest projectors require the least amount of power. There is no way around the fact that, for a projector to be practical, it must output out a great deal of light. Adequate light requires adequate current.
Q:where does the solar energy go to when it hits the solar panel?
I think you got half the answer, but basically like everyone else said, the light hits the electrons and create energy now that energy, since it is now an electrical energy is then saved within batteries connected to the solar panel and that provides the power itself, so as long as there is sun, the batteries will charge up, once the sun goes away, the batteries slowly deplete, but once the sun hits, more energy. =)
Q:Why do people use solar panels?
solar cell is a solar cell solar panel are many solar cells.... Typically people refer to a single solar panel as a solar panel, even though they should be reffering to it as a solar cell. A solar panel is a panel of solar cells working in conjunction with each other. I hope that makes sense it is just the incorrect terminology people always use.
Q:When you get solar panels do you connect them to the grid?
You okorder.com/ as they provide very accurate free solar quotes and break down all the incentives you will be eligible to receive, your estimated annual savings, your payback period, projected IRR, and a cash flow analysis. They taught me everything I know about solar, and I must say they're a great starting point if you're curious about what solar energy is all about.
Q:Run a air conditioner off solar panel?
You can expect such an air conditioner to use something like 500 - 800 watts of power. The ET-P65420 20Wp solar panel produces at most 20 watts so you will need at least three of them. Since solar cells make DC (Direct Current) electricity, and air conditioners use Alternating Current (AC) electricity, you do need an inverter. The M20 is a 220 volt inverter, and I suspect you are looking at a window air conditioner that will probably use 0 volt power. And the M20 only puts out a maximum of 240 watts so you need one for each of the 3 or more solar panels you will have to use. So the first thing to do is shop for air conditioners, getting the most energy efficient model you can find, paying close attention to the voltage and wattage ratings in the owner's manual or on the UL label on the back. Say it is a 500 watt, 0V unit. You will need three solar panels and three 0 volt model inverters. Also note that the 20 watt rating of the solar panels if when the panel is facing DIRECTLY at the Sun. If you just lay them on the roof, then even if the roof is sloped at a good angle (30 degrees) and facing south, it will only produce the maximum power around noon. 4 hours before noon, unless to go up there and tip them up to face the morning Sun they will probably produce only about half that amount of power. So right there you either need a motorized mount to automatically follow the Sun or twice as many panels. However, if you are going to connect the solar panel(s) into the house power, so that it(they) merely supplement the power company power, then you can use any amount of panels, and the power company will supply whatever extra power you need. That requires a licensed electrician to do. Or if you want to just power the air conditioner directly from the solar panels without any interconnection to the house power, then you need to know a lot more about electricity that you appear to know.
Q:0 Watt solar panel question?
It will be less than a trickle charger on the battery. It is about .85 amps at 2 volts dc.
Q:solar panel efficiency in space?
Solar panels on spacecraft are a lot more efficient than ones made for home use. That doesn't include the effect of the atmosphere.
