Details Of Polycrystalline Solar Panel (25W—310W)

CNBM Solar photovoltaic (PV)module is designed for large electrical power requirements.

It is the optimal choice for both on-grid and off-grid power systems.

CNBM Solar panel offers high performance of power per square foot of solar array.

Poly- or multicrystalline silicon(poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified.

Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient.

US DOE data shows that there were a higher number of multicrystalline sales than monocrystalline silicon sales.

 

Main Features of Polycrystalline Solar Panel (25W—310W)

I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IV  AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease.

VII Good performance of preventing from atrocious weather such as wind and hails.

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:Will a 3w Solar Panel Charge A 55ah Car Battery?
Quite a while. I am assuming you are using 2 volts as your buss power. The small panels were intended as a float charge for batteries to keep them from discharging over a period of time. 3 Watts means only /4 Amp. Normally when I do slow charging of batteries, I am using right around amp, and that takes about a week to bring up a battery that was discharged past 80 percent capacity. When you factor in losses from corrosion, battery self discharge, and loose connections, you will likely want to add more panels. using your 55Amp/hour battery, a amp charger running constant in a perfect world would take 55 hours. Real world, probably closer to 64 to 72 hours. That for simplicity is 5 Watts constant charge power. Now you are using /5 of that with your current setup. so 5 times longer, whichh puts you in the 300 hour range of real world, or 220 hours of perfect world. This time of year, you may have about 8 hours worth of charging light, which puts you at close to a month. Don't fret. If you are using it for lighting in a shed, Power LEDs and tethering some of the inexpensive LED lights to the 2 volt source will give you plenty of light for a very long time, the panels will help some, but you will likely need to put the batteries on a charger, or you can build a gas powered 2 volt generator easily enough. Charge it up only when needed.
Q:Why are solar panels grid-like?
Solar cells are semiconductor devices like computer chips. Current manufacturing methods create small squares of semiconductors. Companies are researching ways to make thin film solar cells that can be painted on or manufactured in large, possibly flexible sheets, but so far the technology to do that is still more expensive than making little squares and then assembling them into big panels. That may change in the near future, but I can't be sure.
Q:how to build solar panels?
At first, you will need about one square foot of thin copper plate, two alligator clips and short leads of wire, a wide mouth glass jar, tap water and salt. Cheers,
Q:I have a 6v solar panel , but a 3v dc motor doesn't run with that!!!!?
BECAUSE IT COULD ENOUGH SUPPORT ENOUGH CURRENT, VOLTAGE DROPS DOWN NEAR V WHILE OVERLOADED WITH MOTOR. BUY A VERY LARGE SIZE SOLAR CELL WILL FIX IT.
Q:Wanting to add solar panels to my home?
Ok, well there are also other alternative energy sources, too, besides solar. There is tidal (but you need an ocean :] ), hydroelectric (river, stream, etc.), biomass/biofuels (burning garabage), geothermal (from within the earth, pipes in the earth), wind (windmills, wind, the sun to get wind), and there are others that don't come to mind. Solar energy would cost alot to be installed, and it would take up alot of space, but once installed it pays for itself and uses little to no labor. They all have positives and negatives. All of these are clean and renewable. Here are some sites that my teacher/professor gave us (we just ended alternative energy lesson.) Well I hoped this helped!
Q:Amount of solar panels needed to run a/c and pool pump?
Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
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:Solar Panel Wiring in SERIES?
You should be fine with the series as long as you use a multimeter and verify configuration Get a charge controller. Will be worth the small cost and prevent many issues.
Q:How solar panels and furnaces work?
A solar panel (photovoltaic module or photovoltaic panel) is a packaged, connected assembly of solar cells, also known as photovoltaic cells. The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Because a single solar panel can produce only a limited amount of power, many installations contain several panels. A photovoltaic system typically includes an array of solar panels, an inverter, and sometimes a battery and interconnection wiring.
