Resisting moisture and etching effectively, not effected by geology.

The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

 25w Poly Solar Module With High Efficiency

Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.

The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.

Dozens of these PV cells are packaged together into solar modules, which in turn are packaged into solar panels that are mounted on a rooftop and arranged to maximize their hours of exposure to direct sunlight. Because the electricity generated by all those solar cells is direct current (DC), it is then sent to an inverter that transforms the power into the same alternating current (AC) used by the appliances in your home and the local utility electricity distribution grid. Increasingly, these inverters are getting "smart," providing data monitoring for solar installation performance and other grid integration services.

Q:With everyone thinking green...how green are solar panels?
No matter how electricity is generated you must use materials to build the plant. I don't know what my panels are made out of, and I don't know if they can be recycled. I also don't know what my other electric plant was made of or if it can be recycled. I do know now that it has been made and installed I'm not using coal or oil to make electricity, I'm not creating any emissions, and I won't have to worry about how high the cost of electricity goes.
Q:do solar panels work in aeroplanes?
Depends on the efficiency of your solar panel, but it is highly unlikely that the light in an airplane is enough to do much. I'm not discouraging the solar panel altogether. It just isn't an indoors especially if it is dim on the plane. Most that I've been on turn off the lights and then leave it to the individual to turn on the single over head reading light.
Q:how fast does a 25watt solar panel generate power to a battery?
To figure our how many you need, take a look at your power bill. It will tell you how many kilowatt/hours you used during the month. My bill says I use about 2000 kilowatt/hours per month, or about 2000 kwh /30 days=67 kw/h hours per day. That is 67,000 watt hours. To supply that with solar panels, you have to generate at least 67,000 watt hours, but you don't have a full day to do it, since you have to do it while the sun is up. So you put the energy into batteries during the day, so you can use it at night. A 25 watt panel generates about 25 watts when fully illuminated by the sun. If you fully illuminate it for an hour, you get 25 watt hours. If you get 2 hours of sunlight a day, that would seem to imply that I need 67000 watt hours/25 watts /2 hours=45 panels. But for most of the day, the sun isn't hitting the panel fully, so it isn't going to generate the full 25 watts. When the sun is 45 degrees to the side, you only get about 70%. When the sun is 60 deg to the side, you only get 50%. And what do you do on cloudy days? And the shorter days in the winter? To make up for this, you have to increase the number of panels to make up for the loss. So in reality, I might need double this number of panels, for realiable solar power throughout the year. That works out to about 90 panels, or ,250 watts worth for my house.
Q:Solar Energy Panel VS. Energy Efficient Bulbs?
get a voltage tester and test the output from the panel if it is a 24 volt output which is then inverted the reading should be that of the inverter. however if you solar panel installer installed an LCD panel that controls the electricity you can monitor any faults from the panel. Make sure that the panel you feel is not working is producing the same amount of electricity as the others. As for the bulb buy a new one from a different make and see what happens but by testing the output voltage and power you are bound to find the fault.. I have just thought of this the panels supply electricity to big batteries that then distributes power to all the house perhaps the battery supplying power to your room is faulty or the connections to the inverter might be faulty. BEST option if you can afford it because it will be expensive is to buy a solar monitoring system that control the panel and batteries you can even connect it to your laptop and control all the power.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (July 1, 2004 Japan Sharp market efficiency of 14.8% Of the world 's most efficient polysilicon solar cells).
Q:how do i fix my solar panel? please hurry i need it for my science fair project?
If that solar panel came with the car, the panel is most likely defective. Make sure you're in bright sunlight, and try holding the car so that the wheels are not touching the ground. If the wheels still won't turn, even slowly, then the panel is bad. If each person in the class got one, see if you can try your panel on a friend's car, or their panel on your car. If this is just any little panel, it could be that the panel simply does not have enough voltage, current, or both to power the motor on the car.
Q:are solar electric panels viable in the northwest?
Take okorder.com/.. You need to keep in mind that as long as you are renting your electric from the public utility you are doing just that and renting. You can resale the solar electric system if you move or if you just want to sale it and get some of your money back if not 20 % extra. Then all the years you used the system was all free electric. So it is already viable as you put it. Anything other then buying a system would not be. Here is a thought. The housing market slumped and if you paid 50K for your home it is now only worth if you can even sale it about 00K. Not worth the money but people are still buying homes even if they are not worth what they are being sold for. And then the cars and trucks people buy will never pay for them selfs but people still buy them and spend extra the more wasteful the car is. So why does solar have to pay for it's self or prove it's self? It has many times over but because you can't drive a solar panel drunk and party out in the bars with it is is not worth the money. I guess the is just being human and a double standard. What about the big up front cost of solar? I remember a 20% up front cost when I bought my home and my car and it is the same 20% or less for a solar loan. Plus the value of solar is going up not down like with homes and a car is not worth but half what you paid for it the minute you drive it off the car lot. I can only see good from solar un like other things we buy.
