Solar Polycrystalline Series Panels
Introduction of Polycrystalline Solar 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. Polycrystalline 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.
Characteristics of Polycrystalline Solar Panels
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.

FAQ
We have organized several common questions for our clients，may 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.Normally Speaking, the poweroutput from 250-300W, the FOB Price is $0.6 Per Watt. The detail price need to negotiate according to further situation.
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.
- Q:How do solar panels affect the roof's structure and integrity?
- Solar panels can have some impact on the roof's structure and integrity, but they are designed to be lightweight and installed without compromising the roof's stability. Properly installed solar panels distribute the weight evenly, reducing the likelihood of any structural damage. Additionally, solar panels can help protect the roof by shielding it from the elements, potentially extending its lifespan. However, it is crucial to consult with a professional to ensure proper installation and minimize any potential impact on the roof.
- 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 in mind a small solar panel that could be plugged into a wall socket. Do I need a converter or some kind of interference between the two power sources so there aren't any unpleasant explosions? I don't know much about this sort of thing so please be nice.
- 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:Where can I find updated info about solar panels for home?
- I am a solar consultant within the state of South Carolina. I can answer questions and provide you with links that may help in decision making. Let me know.
- Q:I'm doing a project for school and I'm a little confused about energy and solar panels. I'm looking to propose installation of solar panels to power the computer lab at my school. From what I've read a computer and monitor use roughly 350 watts per hour. I was looking at solar panels and it says they produce various wattage. For example, I was looking at one rated at 200 watts. Does that mean 200 watts in a day? Or per hour? Please help.
- The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
- Q:Can solar panels be installed on bus stops or shelters?
- Yes, solar panels can be installed on bus stops or shelters. In fact, many cities around the world have already implemented solar-powered bus stops and shelters as a sustainable solution to provide clean energy and reduce the environmental impact of public transportation systems. These solar panels can generate electricity to power lighting, information displays, charging stations, and even provide energy back to the grid.
- Q:How long does it take a 5 watt, 2 volt solar panel to charge a 2 volt R.V. battery?
- It is related to the size and capacity of your battery.
- Q:I'm going to pitch an idead to my school about switching to Solar Energy. What are positive and negative effects of the solar panels?Also what is the cost for installing them into a highschool?How much would the electricity bill decline afterwards?
- Solar panels can convert sunlight into electricity which can be used in daily life,solar panels utilize sunrays,it doesn't discharge any polluted gas,it is environment friendly,it is also cost effective,you can make money by sell the surplus electricity to your country, On question is that solar panles have to be use in where sun is abundent.
- Q:Can solar panels be damaged by hail or other weather conditions?
- Yes, solar panels can be damaged by hail or other severe weather conditions. Hailstones can cause cracks or dents on the surface of the panels, which can affect their efficiency or even render them inoperable. Other extreme weather conditions like high winds, heavy snow, or lightning strikes can also potentially cause damage to solar panels. However, it is important to note that modern solar panels are designed to withstand a certain level of weather-related stresses and are often tested for durability.
- Q:During the summer my house uses about .47 kw/h I am wondering what solar panel do I need to cover most or all the electric bill. A link would be helpful too :)
- Are you saying your house continuously draws about .5 kW average all day long? That's 36 kWh per day, if so. This is about double what our house uses year-round, so if you lived in our area, that would be a 6 kW system. The only way to nail down a good number is to get a quote from a local solar installer, though.
