Introduction of  Poly solar panels CNBM

Polycrystalline  Solar Panels 45W With High Efficiency

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.

Feature

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

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

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

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

5.Resisting moisture and etching effectively, not effected by geology.

6.The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

Q:What do I need to use this as a battery charger
I hope this will help you choose your charge controller / battery charger more effectively. Good luck!
Q:How much per sq inch do they cost? Will i have to worry about them blowing off during hurricane season? If the sun isnt out for a week will my power go out? Will I have to check them every week and check which ones arent working and replace them? Is there anyway for them to be damaged by acid rain or any type of erosion like hail? When do I have to replace them? How do I dispose of old ones (like recycling)? What is smarter and more economical having few big panels or many small ones? I know I have alot of questions but I want a good detailed answer.
They don't sell them by the square inch. It costs about $0 per watt of generating capacity. Unless you are connected to the grid you will need a battery bank to storage power for rainy days. As for the effects of weather ... you can probably make a cover out of plywood... but if your house blows away the solar panel goes with it. Before you buy one make sure your insurance covers it.
Q:I have heard you can make your own solar panels.... But How?Where do you start? Is it cheap, or should I just BUY them already made?
if you're hoping to put 'em on your house and use 'em to supplement power from the grid, then you'll want to buy them. the panels have to be made with exotic chemicals, in a clean environment, with dangerous chemicals. anyone who tells you that you can make 'em yourself will be asking for money for the plans. in truth, you could get an old panel, and, if it was the right voltage, you could use it to charge your rechargeable batteries. typically, that's not the hoped for application. and, to get enough power for you house, you're not going to be able to do it yourself. whenever you buy anything, make sure you know what it can do. ie, read the fine print. if it's a few hundred (or thousand) dollars, it's not going to be useful to augment your home power. in addition to the strength, there's also the equipment that's needed to sync it up with the power from the utility, and that's neither cheap, nor a do-it-yourself project. i've seen lots of panels but when you read the specs, they're pretty useless. not good for battery charging, not for hooking up to your house. in other words, interesting projects with no practical use.
Q:What is the average size of a solar panel?
The average size of a solar panel is typically around 65 inches by 39 inches, or approximately 5.4 feet by 3.25 feet. However, the actual size can vary depending on the manufacturer and the specific model of the solar panel.
Q:What is the efficiency of solar panels?
The efficiency of solar panels refers to how effectively they convert sunlight into usable electricity. Generally, the efficiency of solar panels ranges from 15 to 20 percent, with some advanced models achieving efficiencies of up to 23 percent. However, it's important to note that the efficiency can vary depending on various factors such as the type of panel, its age, location, and environmental conditions.
Q:the solar panel works with LEDs, small bulbs,etc but neve with any dcmotor. Please help. I have a science exhibition.
Because its not voltage related its current related. look at the start up values for the motor w respect to current. This will be listed in amps or milliamps. Then cross reference that to the output of your solar panel also listed in amps or milli amps... ;)
Q:Can solar panels be used in areas with high levels of air pollution?
Yes, solar panels can be used in areas with high levels of air pollution. Although air pollution can reduce the efficiency of solar panels by blocking sunlight, advancements in technology have made solar panels more resilient to such conditions. Moreover, regular cleaning and maintenance can help mitigate the impact of air pollution on solar panels.
Q:Can solar panels work in the shade?
They will work somewhat in the shade but they really work best in direct sunlight. I have solar panels on my home and just a cloud passing over will cause the output to drop quite a bit.
Q:Can solar panels be used in areas prone to hurricanes or earthquakes?
Yes, solar panels can be used in areas prone to hurricanes or earthquakes. While these natural disasters can pose risks to solar panels, proper installation and structural reinforcement can ensure their resilience. Additionally, advancements in technology have led to the development of more robust solar panels that can withstand extreme weather conditions. However, it is important to consider local regulations, building codes, and additional safety measures to mitigate potential risks.
Q:Can solar panels be installed on public transportation systems?
Yes, solar panels can be installed on public transportation systems. In fact, many cities around the world are increasingly integrating solar panels onto buses, trams, and trains to harness clean energy and reduce carbon emissions. These panels can be installed on the roofs or sides of vehicles, enabling them to generate electricity and contribute to the power needs of the transportation systems.
