Specification of Solar Polycrystalline(270W-290W)
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.
Characteristics of Polycrystalline Silicon Solar Panel
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.
VIII.Resisting moisture and etching effectively, not effected by geology.
IX.The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

- Q:So I reckon it's time to install some of these bad boys. it's come to point where electricity providers are charging such extortionate amounts that I can definitely see these reaping huge rewards before long. (Okay I might be exaggerating a little - they are pretty costly themselves).The problem is I've read around that they're only fitted to south facing houses? Why so? Why can't they be installed on the rear side of the roof - the side facing the garden? My house is facing north, so the front door leads north. Could I have solar panels installed on the back? (That's basically my question, with a bit of a rant too lol).Cheers.
- You want the panels facing south because that is where they would get the most sunlight throughout the day. If your front door is facing north, then the back of your house would be facing south, right? So put them up in the back where they are facing south...haha wtf..
- Q:Im doing this project on Solar panels and im not so sure what they are!some questions i have are who invented them and what were they invented? If u could know anything on Solar Panels i would love to hear it. Thanks!!!!!!!!!!!!!!!!!!!!!
- Solar Panels are collections of solar cells. These panels basically collect the incoming sun's electromagnetic radiation and convert it into electrical energy. A solar cell is any device that directly converts the energy in light into electrical energy through the process of photovoltaics. The development of solar cell technology begins with the 839 research of French physicist Antoine-César Becquerel. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develop when light fell upon the electrode.
- Q:How do solar panels impact air pollution?
- Solar panels have a positive impact on air pollution as they produce clean, renewable energy without emitting any harmful pollutants or greenhouse gases. By reducing the reliance on fossil fuels for electricity generation, solar panels help to decrease air pollution, improve air quality, and mitigate the harmful effects of climate change.
- Q:Can solar panels be used to power air conditioning units?
- Yes, solar panels can be used to power air conditioning units. Solar panels generate electricity from sunlight, which can be used to power various appliances, including air conditioning units. This is an eco-friendly and cost-effective way to cool buildings and reduce reliance on traditional energy sources.
- Q:How do solar panels affect the appearance of a home or building?
- Solar panels can have a positive impact on the appearance of a home or building. While they do add an additional element to the exterior, the sleek and modern design of most solar panels can enhance the aesthetic appeal. Additionally, the presence of solar panels conveys a sense of environmental responsibility, making the property more attractive to eco-conscious individuals.
- Q:what do solar panels do?
- Solar panels (or photovoltaic panels) collect either light energy (photons) or heat which is then used as energy. Because a single panel can only produce a limited amount of power, there are normally more than one installed.
- Q:I have seen quite a few different websites that talk about building your own solar panels for around $200. I wanted to know if anyone has had any experience with this before I decide to try it myself. It would be very helpful to know what I can expect from such an inexpensive setup; what kind of electronics or appliances would I be able to power. Realistically what can I expect from a $200 setup, and what would I need to power say a whole bedroom (clock, regular sized TV, PC, ext.).

- Q:Here's a little idea I though might help everyone out in Iraq a little: How about if the US mass produces solar panels that are small enough to carry (maybe one foot by three feet) that have a regular power outlet on them to the Iraqis? We could send convoys to the people waiting in line to buy gas and give each person one free solar panel. Why?. A lot of people are buying gas to run generators for air conditioning, not to fuel vehicles. 2. It would help reduce the gas lines if people only needed gas for cars instead of their generators too.3. It would help reduce the fighting over the power grid if people didn't need the grid for their own electrical power.My theory is, once every family in Iraq has enough of these panels that they don't even care about the power grid (during the daytime anyway) it would be much easier to fix the power grid. Maybe these solar panels could even connect to and add to the power grid.
- A big problem with your theory is that because the solar panel is so small the amount of energy gathered from it would be small and probably wouldnt be able to provide electricity for things and even if it did it wouldn't last very long. its a good idea but it just won't work. in order to produce the amount of energy your talking about the solar panels would have to be the size of a roof and be placed on the rooftop or a hill or something. people wuldnt be able to carry that around.
- Q:Can solar panels be used in areas with high levels of chemical pollutants?
- Yes, solar panels can be used in areas with high levels of chemical pollutants. However, frequent maintenance and cleaning may be required to prevent the accumulation of pollutants on the panels, which could reduce their efficiency over time. Additionally, the presence of chemical pollutants in the air may have a negative impact on the overall performance and lifespan of the solar panels. Therefore, it is important to assess the specific conditions and potential risks before installing solar panels in such areas.
- Q:i am doing this group project fro school. I would like to know if anybody knows anything about how to read a Spec. Sheet on Solar panels and where I could go to start researching them. Anything would be great!
- Rate ,power , voltage and effencicney are four important iterms to choose one battery.
