Product Description:

Solar Cells:

solar cells, when struck by photons of light from the sun, generates an electrical current which can then be used to power DC or AC electrical loads.
A solar cell is made of silicon. Computer chips are made of this same material. Basically, when light strikes the surface of a solar cell some of it is absorbed into the silicon. This light energy bumps the electrons loose and causes energy to flow

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.

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:How to manufacture solar cells?
Quality control is important in solar cell manufacture because discrepancy in the many processes and factors can adversely affect the overall efficiency of the cells.
Q:What is the internal structure of solar panels
Very low, but the photoelectric conversion efficiency relative to the crystalline silicon cell more than half of the point, but the low light effect is very good, in the ordinary light can also generate electricity, such as the calculator on the solar cell.
Q:What do the solar cell suppliers provide once we purchase the order from the solar cells from them.
If you are lucky enough or negotiate very well with your solar cells suppliers, you might also get the installation service from them.
Q:Where and how can we find the best solar cells suppliers?
I used to be a solar cells business dealer in the European market for over ten years, and I did not only use the internet to find the supplier, but also go to a lot solar cells industrial exhibition fairs.
Q:Are bulk solar cells better than the normal solar cells?
Yes, the bulk solar cells are better than normal solar cells because its power supply is bigger than the normal solar cells.
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
It's not a easy job.
Q:How long does it take to make a solar cell?
It only took me 1 day because I had all the required materials ready before I start to make it.
Q:How is the solar panel and the battery connected?
Solar cells and battery connection, it is best to use a photovoltaic charging controller, which can control the output voltage of solar cells can protect the battery is not overcharge, but also at night when the solar cell does not generate electricity, to prevent the battery power back
Q:Why should the solar cells be laserized?
Compared to the mechanical scribing in terms of slag will not cause short circuit, laser scribing is non-contact processing way, will not cause damage to the substrate.
Q:What should I know about the Crystalline silicon photovoltaic cells?
Crystalline silicon photovoltaic cells, known as cSi PV, are made of silicon atoms connected to one another to form a crystal lattice. This lattice comprises the solid material that forms the photovoltaic (PV) cell's semiconductors.
