Solar Polycrystalline Series Panels

Introduction of Solar Polycrystalline Series Panels

CNBM Solar photovoltaic (PV) Panel 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. 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. Hence most c-Si panels have uncovered gaps at the four corners of the cells.

The Examination of Solar Polyocrystalline Series Panels







We have organized several common questions for our clientsmay help you sincerely


1.       What’s price per watt?

A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.

2.       Can you tell me the parameter of your solar panels?

We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.

3.      How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

Normally we put the panels in carton and then in pallets.

4.       Can you do OEM for us?

Yes, we can. It will depend on the quantity.

Q:2v about 600ma Solar Panel?

Q:Why dont we have a gigantic solar panel system in the warm states,stretching miles across to supply the usa?
Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!
Q:How are solar panels developed and distributed in America?
The first link below is one of the best sites for recent news about solar panels. You should be able to find stories about solar panels under development today. A little bit of the history: Solar panels have been around for about 50 years now. They were first used to power spacecraft. Solar power for domestic use started to develop rapidly in the 970's during the first oil crisis, but as energy prices fell in the 980's solar development slowed. Most of the large solar panel makers were purchased by large oil companies who seemed not to be too interested in solar. In the late 990's as concerns about both Peak Oil and Global Warming grew there was renewed interest in solar power and a number of new companies were started to develop new kinds of solar panels. Many of these new companies have grown larger than the older solar companies still owned by big oil companies. Over the last 7 years or so growth in the solar market has been explosive with a compound growth rate of almost 40% per year. In 2005 the solar industry for the first time started to consume more silicon than all other electronic industries combined resulting in a world wide silicon shortage that is still with use. New silicon refineries are coming on line and the shortage is expected to diminish by 2008 or 2009. Check out the two links below. They will help you a lot.
Q:Why are solar panels placed on the roof of houses?
Solar panels are placed on the roof because many times the roof has good exposure to the sun providing the roof is not blocked by trees or something else so that sufficient sunlight wouldn't be absorbed. Also the panels would more likely not get damaged on the roof opposed to being in the yard. If they were mounted on the windows, how could you see? And, the windows could easily break and then what would happen to the panels? Placing the solar panels on the floor would not be practical. A lot of sunlight is needed for the cells to produce electricity and how much goes on the floor? Most roofs are at an angle which could perhaps improve the amount of sunlight the panels would get, and roofs provide a lot of unused space. The roof is the best place. Furthermore, roof solar panels are available now to blend in better with the roof so that they are more pleasing to the eye. Even if you have a small roof, some panels could be placed there provided the roof is not blocked so that the sunlight it gets would be sufficient (about 4 or 5 hours of sunlight a day is needed). And, if you needed addition panels, they could be mounted in your yard as long as the mount was close to your power box and received sufficient sunlight. I applaud your desire to use solar panels. You could possibly save 50 - 90% on your electric bill and help your environment at the same time! A Win - Win situation!!
Q:Can I plug a solar panel into a wall socket to lower my electric bill?
You can use a solar panel to heat water, and you can generate electricity, but you can't plug it into a wall socket. The most effective way to save on your energy bill is by heating water. Solar panels that produce electricity, don't store it. They produce it for that particular time, and if you're not there to use it, it's gone. Furthermore, the electricity isn't always regular, it may have peaks and shortages. The best way to tap into that, would be to sell the electricity you produce to the grid, and then buy it back when you use it.
Q:How much does it cost a factory to make a solar panel?

Q:How tangible do horseshoe solar panels sound?
The panel's own shadow at different times will defeat the purpose. In addition large areas of expenssive panel will remain idle. Flat panels are the most economical solution.
Q:question about GE solar panels?
I wasn't aware that GE made solar panels. Perhaps they sold their name to someone, as they've done for all of their consumer electronics. But a 90-watt panel is $66.20 from the place below.
Q:Why don't we use solar panels?
Actually there was talk about doing some major solar installations in New Mexico and Nevada. Unfortunately our government put a temporary hold on all large scale solar installations because they feel that they might hurt the local wildlife and more studies need to be done. So, now the huge installations have been put in line and have to go through a bunch of bureaucratic nonsense. Also, just so you know, large solar installations dont generally use photovoltaics. they use concentrating mirrors and concentrate the sun on a pipe with some sort of liquid in it which boils and runs turbines.
Q:What is the most powerful solar panel made?
Yeah lead acid is the desirable yet once you've a higher image voltaic setup like 200watts or extra you extremely want a cost controller in addition they favor to be vented because even as they're charged the produce hydrogen that once concentrated burns and is no longer good to respire in. the worst section about lithium ion is they imeadiatly commence to decompose once they're used so that they in straight forward words very last 2-4 years the position lead acid can very last over 2 years if good maintained.
