Product Description:

Introduction of  Poly Solar Panels CNBM (250W-260W)

Poly Solar Panels CNBM (250W-260W) 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 Solar Panels CNBM (250W-260W)  of Monocrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon.If you have interest in Poly Solar Panels CNBM (250W-260W) ,please contact us!

Q:SunPower Solar Panels?
There is no difference between them besides their rated output. One may physically fit on you roof better than another, or look better, although the physical difference between those sizes is minimal. Go with whichever installer you trust, and is preferably NABCEP certified, or working towards NABCEP certification. Get references. Don't believe just because someone is an electrician they know how to install solar electric, it's a whole different animal. Make sure they are trained in installing solar.
Q:Hey. I need some help with solar panels and batteries :) Please see the detailed version beneeth :)?
One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .

Q:Which spectrum of sunlight generates the electricity in a solar panel?
I think it's in the Ultra-Violet range because Solar Panels will still put out almost full power on an overcast day.
Q:What to do with a solar panel?
Hey AJ, Tom is quite right, a panel that size is a great trickle charger at .2 amps. If you have a good sized 2 volt battery, like from a truck, or for a boat trolling motor (it should be at least 60 amp hours) you can hook it to the battery and it will charge it slowly anytime the sun shines. Don't worry about the voltage, most 2 volt nominal volt panels are wired for 8 - 9 volts, and if you hook them to a battery, the panel voltage comes right down to the batteries charging curve voltage anyway, they are designed for that. What you do need is a diode. A diode is an electrical check valve, allowing current to flow in one direction, but not the other. This will prevent the battery from discharging through the panel at night. Many panels today come with diodes inside the junction box on the back of the panel. If yours does not have any, go to Radio Shack, look for a 6 amp silicone diode, usually around75 cents. Put it in series between the panel and the battery, then, while you have a voltmeter hooked to the battery, connect the panel/diode to the battery and see if the voltage goes up slightly. If it does, you're all set. If not, turn the diode around and try it again. It has to be connected into the circuit the correct direction. Many people will state that you need a charge controller, but this is not necessary if your panels max current, ISC is less than 2% of your batterys amp hour capacity. In your case, if you have a 60 AH or larger battery, skip the controller. There is a great discussion about this in Richard Perez's book, I will list it below. If you want to learn more about these devices, there is a great magazine that gets into the nuts and bolts of renewable energy, it's called Home Power Magazine, the link is below. We started by hooking a slightly larger panel to some golf cart batteries 2 years ago, reading that magazine and going to some energy fairs. Today our home is completely powered by the wind and sun. Check it out sometime. Take care, Rudydoo
Q:How much electricity does a solar panel generate?
Actually, there's about 000W per square meter of optical power from the sun. Solar cells cannot collect all of that power though. In fact, most solar panels are only about 5% efficient (though some can be around 20%). So that means a solar panel that is square meter can only provide about 50W, not 000W. And that's only during peak sunlight hours.
Q:Why should I use solar panels?
How Solar Cells Work by Scott Aldous Inside This Article . Introduction to How Solar Cells Work 2. Photovoltaic Cells: Converting Photons to Electrons 3. How Silicon Makes a Solar Cell 4. Anatomy of a Solar Cell 5. Energy Loss in a Solar Cell 6. Solar-powering a House 7. Solving Solar-power Issues 8. Solar-power Pros and Cons 9. Lots More Information 0. See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
Q:energy and solar panels?
It depends on the size of the solar panels and the intensity of the solar-light. So, there's difference in every place. It's impossible to answer unless there's detail of panel size, panel quantities, average rainfall, average solar days, etc.
Q:Solar panels for a netbook?
That strikes me as completely impractical for most circumstances. The power output of your mains adapter is 30W and to do that you are looking at at least five or six square feet of solar panels costing in the region of $600 even from a surplus supplier I know. You could do it cheaper (maybe $50 on panels) but then you would be looking a more primitive panels and need perhaps thirty square feet of solar panels. This is a completely different exercise to creating a solar powered USB charger - the power requirement is a lot higher. Astronomy and space?
Q:background of solar panel?
Photovoltaic cells work because of the photoelectric effect. However, a solar panel can actually be using several different technologies that have the same common effect of generating electricity when the sun shines on them.
