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:What is the working principle of a solar cell?
The solar cell works in the way that use the sunshine as the resources to generate the power for us to use.
Q:Can solar panels be charged with light?
When the external circuit is turned on , In the role of the voltage, there will be a current flowing through the external circuit to produce a certain output power. The essence of this process is the process of converting photon energy into electrical energy
Q:What is the best way to deal with surplus solar cells abandoned after burning?
It could be a very good resource to be used, but the technology needs to be more advanced to really deal with that.
Q:Solar cell life for several years
In physics called solar photovoltaic (Photovoltaic, photo light, voltaics volts, abbreviated as PV), referred to as photovoltaic.
Q:How do people price solar cells? Is it based on a specific way of calculating the cost of solar cells?
Here is an example of doing the calculation, just for your reference: According to the same calculation method, 10 kilowatts of distributed photovoltaic power generation equipment to recover the cost of 9-10 years. Home photovoltaic power plant to recover the cost of the average period between 8-10 years.
Q:What is a polymer solar cell and how does it work?
It's one kind of solar cell that works in the same way as other solar cells do.
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
The process of solar cells' conversion first requires a material which absorbs the solar energy (photon), and then raises an electron to a higher energy state, and then the flow of this high-energy electron to an external circuit. Silicon is one such material that uses such process.
Q:Can I buy solar cells easily online?
Yes, you can.
Q:What kind of products can be considered as the solar cell products?
I think there is nobody else but me could be as qualified to answer this question because 80% of my daily life is surrounded by solar cell product including solar cell shower room, solar cell equipt kitchen, solar cell control lights in all my rooms in the house.
Q:What's the relationship between solar energy materials and solar cells?
There are solar cells made of many different kinds of materials, for example: Silicon thin film, compound semiconductor thin film and organic thin film shape, hundreds of compound semiconductor thin film shape and non crystalline shape (a-Si: H, a-Si:H:F, a-SixGel-x:H) III V family (GaAs, InP), II VI (CDS) and zinc phosphide (Zn3P2).
