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.
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:im aware i dont fully understand. but with what i do. if P = iv, and current changes with voltage, whats the point of changing either. if in any cicumstance, you end up with the same wattage, how does changing either effect a solar setup. (2v panel vs 24v)thanks in advance. explain in laymans if you can.
- The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.
- Q:With no moving parts, no fuel piping and so on...
- ITS TO DO WITH THE PRODUCTION PROCESS
- Q:Is there any way to charge my laptop with a solar panel? Is there any panel like that. Or if I work on panels can I do something like that. If you know anything about it, can you just help me? Thanks a lot.
- A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
- Q:I know what they do and how they work, but at this point they're expensive, don't always produce enough electricity as needed, and can't be used when there's no sun, as in half the day. Wouldn't wind power seem so more efficient? Or if they do use solar panels, how about putting them in the desert. But I really believe that research money should go to fusion generators since that's the future and the answer to our problems. Which is best in your opinion?
- There is not a yes or no answer. But for the majority of the population it is a definite no. Because the energy needed to make a solar panel is more than the energy that a solar panel can return in its life time. so No for cities and urbanized areas because there is already existing infrastructure therefore you'll be wasting more energy getting them installed. And it is better and more efficient to have the more common energy sources for populated areas. However that being said it would be more efficient if you live in a remote area as it would not be worth it to build a huge electricity grid just to power one small house in the middle of no where.
- Q:I found portable solar panels used for boats etc. and was wondering how I could effectly use them for my home instead. If you have used them in the past, please tell how they worked (good or bad).
- from what i have seen and heard the portable panels you are talking about are not big enough for home use unless you create a specific outlet to use them on such as one for cellphone charger or other small use items. Just my semi-educated guess.
- Q:Can solar panels be used in commercial buildings?
- Yes, solar panels can definitely be used in commercial buildings. In fact, many businesses are increasingly installing solar panels on their rooftops or in open spaces adjacent to their premises. Solar panels are a sustainable and cost-effective solution for generating renewable energy, reducing electricity bills, and lowering carbon footprints in commercial settings.
- Q:I have just made my first dolar panel 20 watts, charges my 27TMX Trojan battery perfectly. Now I am thinking to build more solar panels for a grid tie installation at my house, maybe 5 panels would do it, is this safe?

- Q:How much energy can a solar panel produce?
- The amount of energy a solar panel can produce depends on various factors such as its size, efficiency, location, and the amount of sunlight it receives. On average, a typical solar panel can generate between 250 to 400 watts of power per hour.
- Q:What Are Solar Panels Made Of?
- Solar panels are instruments made from Silicon Cells having the characteristic to convert solar energy into electricity. Sunlight is composed of miniscule particles called photons. When the sun’s photons are consumed by the silicon atoms of the Silicon Cells, the atomic creation of the solar panel is organized in such a way that electricity is generated. When these solar cells are accumulated together with wiring, they become one concrete panel.
- Q:Can solar panels work during cloudy or rainy days?
- Yes, solar panels can still work during cloudy or rainy days, but their efficiency is significantly reduced. Solar panels generate electricity by converting sunlight into usable energy, so the amount of energy produced is directly related to the amount of sunlight available. Cloudy or rainy weather reduces the intensity of sunlight reaching the panels, resulting in a lower electricity output. However, solar panels can still generate some power even in these conditions, making them a viable source of renewable energy even on less sunny days.
