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: i check the diodes in the backside of solar panels it reads out to be 0.433 each give me the same result but i was amazed when i check out the last two one which on clamp meter screen give me ''0L'' what this means? is that diode have malfunctions??is this reasons that the output of solar has been decreased?
- First of all, make sure that you are taking readings in the dark (with the solar panel indoors and covered). 0.433 is a reasonable forward voltage for a Schottky diode. Ideally, it diode should read open one way (possibly OL for your meter), and 0.4 the other way. If it's reading OL both ways, the diode is bad. You can either unsolder it or cut it out and verify that it is bad.
- Q: How do solar panels affect the property's curb appeal?
- Solar panels can enhance a property's curb appeal by making it appear more modern, eco-friendly, and energy-efficient.
- Q: . Does it really only cost $200 in contrast to $5000 or more?2. How much would it cost to build panels that would energize an entire average household? (washer, dryer, water heater, lights, fans, a/c)3. Is there a place to get the info on how to make them for free instead of paying E4E?4. Are the professional solar panels better? more efficient? 5. Will the electric company in So. Cal. really pay you?6. Do you have to be certified to do this professionally? or an electrician? If so what schools teach it?7. Would wind generators be of any use in So. Cal.? I mean don't you really need to get the fan spinning to get energy?8. Are there any extra unseen costs? (tools, energy converter, ect)9. How much is it to get an electrician to hook you to the grid?0. Is it better to hook to batteries or the grid? Pros, cons, why?
- I believe Earth4Energy to be a bald-faced scam, selling plans that will not do what is implied in the marketing, and imparting no information that is not publicly available on the internet, already. If you were to search for solar panel on torrent sites, most likely, some disgruntled customer has posted the material. It probably violates the E4E copyright, so I'm not suggesting that you get it in this manner. I'm going to skip many of your questions, given my already-stated opinion of Earth4Energy. Professionally-installed panels have a net cost of thousands of dollars in general. While they can save money (and Southern Cal is an ideal place for this), consider that it generally takes 0 years or more to get your money back. If you're on S Cal Edison, or SD Gas and Electric, you can go on net metering. They don't really pay you, they credit your electric bill. After a year, if you used more electricity than you generated, you pay them. If you generated more than you used, they reset the balance to zero and say thanks for your donation. You never really get a check, like in some other states. But you should have lower electric bills. You can put up panels for your own use without any certification. To put up panels professionally, you'll need a C-0 contractor's license from the state, or will need to be under the supervision of someone with such a license. But if it's the latter, you might just be the grunt that carries the panels off the truck and up the ladder, for minimum wage. I'd say better than 95% of residentail solar is connected to the grid, if the grid is available. It's a clear winner. Who wants to pay 50% more for their system, just to have batteries that need their water and acid checked all the time? Below is one of many unsatisfied customers from Earth4Energy. Be careful in your search, people selling these reports have bought up the keywords such as scam and ripoff to direct you back to sites selling the product.
- Q: What is the average annual energy output of solar panels that can be installed on the home?
- The output of a solar panel would depend on your location and panel size. Most solar panels are rated using 000 Watts per square metre from the sun. This is only possible at the equator. Some supplier have online estimators for output depending on your location. Solar panels rate up to about 250 Watts per panel. I have an online calculator to work out the costs and benefits of solar. You can compare the costs of solar setup and 25 years of electricity versus buying from the grid.
- Q: i know that a solar panel of square meter generate 000 watts on a clear and sunny day, but i need to know the time rate. is it 000 watts per day or per hour? Thanks.

- Q: Is there a material that is capable of absorbing enough UV radiation to make it worth using as a flexible solar cell?Not flexible as in aluminum, but a material such as plastic (polycarbonate).
- Homemade okorder /
- Q: Can solar panels be installed on a multi-story building?
- Yes, solar panels can be installed on a multi-story building.
- Q: How much energy can a solar panel generate?
- The amount of energy a solar panel can generate depends on several factors, including its size, efficiency, and the amount of sunlight it receives. On average, a typical solar panel can generate between 250 to 400 watts of power per hour. However, larger and more efficient solar panels can produce even higher amounts of energy.
- Q: If you buy everything you need for a grid-tied solar set up, can you install it yourself or is it required that a professional installs it?
- Solar panels have to be installed by a professional in order to get the government rebates. Also the systems must meet state and local electrical codes. Most modern inverters will not turn on unless there is live power from the MAINS, so a ultility company is NOT required for any installation anywhere. There are plenty of electrical contractors and speciality solar contractors out there to help you to make sure that the system is properly designed with the correct components, properly installed, and legally certified. Also many states require a permit that may have a large fee before any installation and may not allow the homeowner, especially for city homes, so it is best to check first. You might be able to get away with it if you live in the country, but consider the safety as well. See if you can work with your contractor to get the materials that you both agree upon as well. They can help guide you based upon their experience. Also shop around for pricing as the panels are now going below $ per watt !
- Q: There is a charge controller that has what i believe to be only port for a solar/ wind turbine control panel and i don't know if it has more than port for panels. So would i be abed to link 2 panels to port or do you think the controller has more than portBTW it is for marine use.
- No problem linking them in series.
