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:Anybody ever heard of thin film solar cell? What it that?
I did hear that term once, but can't remember what it is.
Q:Can I trust the suppliers for film solar that I found on alibaba.com?
I have been doing business on alibaba.com for over 10 years, and I seldom came across the unreliable suppliers from alibaba.com. Therefore, I should say I do trust the suppliers I found.
Q:My son is very interested in solar cells recently, and keeps asking me about the structure of a solar cell. Can anybody help me answer that question?
My way to deal with the questions from my son is to search together with him on line, and learn with him together.
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:How to explain to students how the solar cells are made?
The Manufacturing Process of solar cells is a bit difficult to explain, but I can send you the details through email if you want.
Q:How many solar cells are there in a solar panel?
I need to know the power of the solar panel to answer the question.
Q:What is Solar Cell Technology?
A newly-developed technology which can help us get a lot energy from the sunlight.
Q:The difference between a fuel cell and a solar cell
building blocks of the scale and installation of flexible, fuel cell power plant area is small, the construction period is short, the power station can be assembled according to the needs of the battery stack, very convenient.
Q:What is the most commonly used material for solar cells?
The most commonly used solar cells material is the solar photovoltaic (PV) cells. They are used for the direct conversion of light energy into electrical energy. At present, a large number of terrestrial photovoltaic systems are made by silicon solar cells, which can be divided into silicon, polycrystalline silicon, amorphous silicon solar cells.
Q:Where can I buy solar cells?
Maybe at the local equipment shop?
