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.

Features:

High efficiencies up to 16.4%

Proven long term mechanical stability of silicone

Make of highly purified poly silicone

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

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

Acid texturization offers a uniform appearance and virtually invisible crystal structure

Excellent low light behavior for improved energy yield

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:Solar water heater plate can be directly converted into electrical energy?
solar controller: the role of solar controller is to control the working state of the entire system, and the battery played a charge protection, over discharge protection role in the larger temperature difference, the qualified controller should also have the temperature Compensation function. Other additional functions such as light control switch, time control switch should be the option of the controller;
Q:What do the solar cell suppliers provide once we purchase the order from the solar cells from them.
The solar cells suppliers might also help you to finish you solar cells installation process, which is considered to be a necessary but valuable service they can provide to the clients.
Q:Is A grade better than the B grade when we buy the poly solar cells.
The poly solar cell with A grade means the sustainabilty and quality of the poly solar cells are better than the others.
Q:Solar cells and the difference between ordinary batteries. Why is the solar cell is converted into electrical energy, zinc battery is what is converted into chemical energy
Ordinary batteries have a certain life, can not be stored for too long, or the power will slowly run out of solar cells do not exist chemical failure, can be long-term preservation.
Q:How can I explain to my 10 year old daughter what solar cells are?
You should expain it to your daughter in a simpler way instead of the complicated scientic way.
Q:What is the internal structure of solar panels
In addition to the quality of EVA itself, the components of the manufacturers of the laminated process is also very large, such as EVA glue degree is not up to standard, EVA and tempered glass, backplane bonding strength is not enough, will cause EVA early aging, Affect component life.
Q:How much does a solar cell cost?
I never did the exact calculation, but it does cost much more than I thought.
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 solar cells market in China?
The Chinese market is booming, but the solar cells' market was developed 8 years ago. It was supported by the Chinese government before because the whole country has been aiming at saving energy and protecting the envionment.
Q:What is a good introduction of solar cell?
In my opinion, a simple and interesting experiment would be a good start.
