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: Is there a free site or resource that will teach you how to do this? Hopefully step by step and tells you how to buy all the parts ect?Which is the best resource for sale earth4energy, homemadeenergy, ect? Do they actually work and also as well as those which are professionally done?They say it will cost under $200 for a panel, but how much will this panel actually produce I mean how many panels would you have to make to produce 00% of your homes energy?
- I have no idea the out put of the panel you plan to make, but $200.00 will not even come close to power much. You don't say whether you want to power your house straight from the solar panels (not possible, because the sun doesn't shine 24/7). That being said,you will need a very large array to power your house,going to battery's to inverter to get AC power. Your initial cost would be around $25000,00, but you might be eligible for a tax rebate and maybe a rebate from your state and power company. There is a lot more to be said on the subject,but this is enough to either get you started or discouraged.
- Q: Can solar panels be used in areas with high levels of dust storms?
- Yes, solar panels can be used in areas with high levels of dust storms. However, it is important to regularly clean and maintain the panels to ensure optimal performance. Dust storms may cause a temporary decrease in energy production, but it can be mitigated by implementing proper maintenance practices such as cleaning the panels and installing protective measures like dust shields.
- Q: I mean like bread is made of wheat, what are solar panels made up of?How are they manufactured?
- Solar panels (aka photovoltaic panel) are most often made up of thin wafers of crystalline silicon or cadmium telluride. As photons from the sun enter the photovoltaic cell, electrons are freed from the substrate when are then collected by wires that run throughout the panel. And as we know electrons=electricity!
- Q: i am looking for solar panels and wind mill to put around our house and i was wondering were to find them
- Your best bet would be to go down to a place that has magazines and look through their solar magazines, like Solar Today and Home Power. In these you'll will find many places online where you can buy solar and wind power products. They also have good reviews so that you can be an informed consumer and don't end up buying poor quality products. I've seen performance reviews on a variety of models.
- Q: Are solar panels recyclable?
- Yes, solar panels are recyclable.
- Q: Heard you can put solar panels on laptops Anyone know if it can work on a Dell mini 0v? I've seen he USB slot solar pana but can someone tell me where to gt these?
- If okorder /
- Q: I was told by a veteran that jcpl had a program that installs free solar systems for disabled vets.If this is true who do i contact?
- yes. there is a free solar panel program for veterans.
- Q: What makes them stop working after a while?
- could be temperature, poor design and U-V damage If they are outdoor lamps like mine it is more likely the rechargeable batterys are bad.
- 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 Power. There is no denying it, solar power works. Not only is it energy efficient, it is also safe and extremely clean. Whether it may be for a home, business or a community, there are no limits to the energy that the best solar panels are able to offer.It is a guarantee that once this medium is applied, you would easily slash your greenhouse gas emissions and electricity bill.
- Q: With no moving parts, no fuel piping and so on...
- It's all in the production process that uses materials and processes that are not yet cheap because of the little infrastructure in this field. You can make cheaper solar panels, but it restricts their efficiency, so you get less energy. The reason individuals haven't been catching on to it is because it is not yet entirely cost effective. For a normal 3-person home to be powered completely by solar, depending on many conditions, especially where you live, the payback period is something over 50 years. I live in Boston and for my house to be powered by solar I wouldn't see it making money for over 75 years! What people have to realize is that the point of solar is not to completely power your house cheaply, but to lessen the strain on the electrical grid, and if enough people do this the cost will certainly come down. That and the technology of solar panels has been developing unbelievably fast with all of the green energy buzz going around, so you should see the cost dropping in the next few years as new discoveries are made.
