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 of 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.

 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:Which brand of the solar cells is sold with the lower price on the market? Which brand is more practical for the countryside?
Sometimes the lower price solar cells mean you might have to take the risk of low quality solar cell.
Q:What is the best way to deal with surplus solar cells abandoned after burning?
The surplus of solar cells can be very useful or useless at all. Totally depend on how people try to apply it to the new construction work.
Q:How can the huge solar cells be applied into the market?
If you are just using power supply for daily usage, such as a family of 6, you don’t need the huge solar cells.
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:What are the advantages of monocrystalline silicon and polycrystalline silicon in solar power?
In the use of solar energy, monocrystalline silicon and polysilicon also play a huge role. Although the current terms, to make solar power has a larger market, the majority of consumers to accept, we must improve the efficiency of solar cell photoelectric conversion, reduce production costs. From the current development of international solar cells can be seen that the development trend of monocrystalline silicon,
Q:Can the solar powered cells really work better than the normal cells?
There is no doubt that the solar powered cells work better than the normal cells, the only disadvantage is the cost of making it.
Q:How to generate solar cells, the principle of PN junction
Salt, such as gallium arsenide III-V compounds, cadmium sulfide, copper indium selenium and other multi-compound materials for the battery; 3, functional polymer materials prepared by the large solar cells; 4, nano-crystal solar cells.
Q:What's the benefit of using a solar cell?
It can help avoid the greenhouse effect.
Q:What kind of products can be considered as the solar cell products?
Solar cell product, as simple as it is, is the products which is made of solar cell, or generated by the power converting from solar cells.
Q:What are the 3 things you need to know before you start to make solar cells?
There is another easy way to make a solar cell by using 2 small sheets of brushed copper and setting 1 of them on the hot plate for half an hour until the copper turns black. Some magic will happen.
