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.

 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:What do the solar cell suppliers provide once we purchase the order from the solar cells from them.
Some of the solar cells suppliers will also provide the construction of the solar cells for your project.
Q:Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?
We seldom see poly solar cell with the size of 152, because that is not really good to use.
Q:How can I describe solar cells in a simple way?
Solar cell is a specific battery.
Q:Where can I buy solar cells on sale but still good quality ?
Good solar cell sellers can get the best solar cells with highest quality as they have very strict quality control from material-during manufacturing-assemble-package; and they also check and test the structure strictly to ensure the whole solar mounting system can work under extreme weather condition;
Q:What is a monocrystalline Silicon Solar Cells?
Monocrystalline Silicon Solar Cells consist of silicon in which the crystal lattice of the entire solid is continuous, unbroken to its edges, and free of any grain boundaries. Mono-Si can be prepared intrinsic, consisting only of exceedingly pure silicon, or doped, containing very small quantities of other elements added to change its semiconducting properties.
Q:How can I calculate the cost of using solar cells if I put a fully-functional solar system in my house?
Depends on how you define the "cost" of the solar cells, if you are only calculation the electricity you used, it really cost nothing.
Q:My solar cells are broken, can I just buy one and replace it?
No, you just can not do properly
Q:How can the huge solar cells be applied into the market?
It depends on the market needs for large electricity needs.
Q:Can a solar cell be used in commercial buildings?
Yes, of course, it can .
Q:How to get high voltage and high current output of solar cells?
Here is the way I tried by myself: Using 0.5 880 volt 5 ampere output of the battery board, in series 440 as the first group, and then get a second group, and then put the two groups in parallel, you can get what you want.
