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:I would like to use a ppt to show how solar cells can work in a power generation factory, can anybody share some useful information with me?
To make it simple, solar cells are high technology that generates power through the sunlight.
Q:Is it complicated to make a solar cell work well?
A solar cell is a physical and chemical phenomenon.
Q:Is the Photovoltaic cell panel good to save the energy?
There is no doubt that the photovoltaic cell panel is very useful and efficient in saving the power in human's life, not only daily life but in other industries.
Q:What is the working principle of a solar cell?
A Solar cell works by using the sun's energy to enable electrons in semiconducting materials to move from orbits close to the nuclei of their atoms to higher orbits where they can conduct electricity.
Q:How can I understand the working principles of solar cells?
My way of understand the working principles of solar cells is to read tons of books about that topic.
Q:Why and what is the low efficiency solar cell?
Sometimes the solar cells made of bad quality silicon can cause the result that the solar cells you are using is lower efficient than when you started to use it. You might need to change some materials.
Q:Is there any easy way to make a solar cell? I want to make a DIY solar cell with my child at home.
I sent a private message to you about my personal experience of diy solar cell.
Q:How can I calculate the cost of using solar cells if I put a fully-functional solar system in my house?
Sunrun solar lets you get started for as little as $0 down, but to install it, it will cost you a lot.
Q:How can I buy the solar cells wholesale ?
Please feel free to contact us, a solar cell production company based in Zhuhai, Guangzhou Province. We can offer you the best wholesale price with very good quality.
Q:Is the polymer solar cell the cheapest type among all the different kinds of solar cells?
Yes, the polymer solar cells are the cheaper type.
