Product Description:

 Solar Cells:

Solar cells is made by solar wafer, it has three categories of solar cell right now, monocrystalline polycrystalline and thin film,These cells are entirely based around the concept PN junction, which is the critical part of solar module, it is the part that can convert the light energy into electricity, the thickness is from 180um to 200um, with even busbars to conduct electricity, textured cell can decrease diffuse reflection; they are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting  semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. Connecting cells in parallel will yield a higher current;With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

Features:

1. High conversion efficiencies resulting in superior power output performance.

2. Proven long term mechanical stability of silicon

3. Make of highly purified poly silicon

4. Three bus bars for reduced series resistance and improved module and cell efficiency

5. Blue anti-reflecting coating ensures improved light absorption and increased efficiency

6. Acid texturization offers a uniform appearance and virtually invisible crystal structure

7. Excellent low light behavior for improved energy yield


 Solar Cells Advantage:

•  High efficiency and stable performance in photovoltaic conversion.
•  Advanced diffusion technique ensuring the homogeneity of energy conversion efficiency of the cell.
•  Advanced PECVD film forming, providing a dark blue silicon nitride anti-reflection film of homogenous color and attractive appearance.
•  High quality metal paste for back surface and electrode, ensuring good conductivity, high pulling strength and ease of soldering.
•  High precision patterning using screen printing, ensuring accurate busbar location for ease with automatic soldering a laser cutting.

 FAQ

We have organized several common questions for our clients,may help you sincerely:

①What price for each watt?

It depends on the efficiency of the solar cell, quantity, delivery date and payment terms.

②How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.

③Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Yes, we can, we have two companies for solar region, one is CNBM International, the other is CNBM engineering Co.

We can provide you not only the solar module but also the off grid solar system, we can also provide you service with on grid plant.

④What is your warranty of solar cell?

 Our product can promise lower than 0.3% open box crack, we support claim after opening the box if it has crackm color difference or sth, the buyer should give pictures immediately, we can not accept the claim after the solar cell has assembled to solar panel.

• Timeliness of delivery

• ⑤How do you pack your products?

We have rich experience on how to pack the solar cell to make sure the safety on shipment, we could use wooden box or pallet as buyer's preference.

Q:Where and how can we find the best solar cells suppliers?
I usually use to find the solar cell suppliers here: 1 alibaba.com, 2, made-in-china.com 3. globalsources.com
Q:How to get high voltage and high current output of solar cells?
If you want to get the high voltage and high current output of the solar cells, you can put them in serial and serial-parallel approaches.
Q:How does the solar cell work in terms of photochemical conversion?
If impurities are incorporated into the true semiconductors, i.e. monocrystalline silicon, for example, incorporation of pentavalent phosphorus (P), excess electrons are called, which are called N-type semiconductors.
Q:Can solar panels be charged with light?
Since the output power of solar modules depends on factors such as solar irradiance and solar cell temperature, it is not recommended to use light charging, efficiency is not only very low, and also meaningless.
Q:How does the solar cell work properly?
The material which is used to absorb the energy from sunshine should be silicon.
Q:How about the current market price for the film solar?
The price for the film solar in the Chinese market is changed a lot due to the mass production of the film solar in a lot of factories.
Q:How long is the long cycle solar cell life?
There are discharge depth, such as each time the actual capacity of the battery only 30% of the battery, you can cycle more than 1500 times, that is, 4 years or so, but if every 80%, then only more than a year, 100% It is about 1 year it
Q:What do the solar cell suppliers provide once we purchase the order from the solar cells from them.
The good solar cells suppliers do not only sell you the solar cells products, they also give you very useful suggestions to help you install it.
Q:How many types of solar cells are now being used in real life?
Generally, there are two types of solar cells, one is Monocrystalline silicon solar cells, the other is polycrystalline silicon solar cells
Q:Is the solar cells factory in China good and trustworthy?
I can only say 50% of the solar cell factories in China are good, and they can meet your quality standard, while the other 50% of the solar cell factories are not very reliable.
