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: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:How many solar cells are there in a solar panel?
It's hard to tell because it depends on the voltage.
Q:How does solar cell technology apply to our daily life?
It is used in different ways, such as electricity, water supply, etc.
Q:What is a High-efficiency electric solar cell panel?
We should first check if the power output performance are stable, if not, no matter how high the power supply would be, it is not efficient but just unsafe.
Q:How about the current market price for the film solar?
The a-Si ( Amorphous Silicon) thin film solar cells, with the advantage of short energy recovery period, simple manufacture process, inexpensive cost, good performance at high temperature and deposition on the flexible substrate, have been commercially produced and used in daily life.
Q:Where can I buy the 156x156mm high efficiency poly solar cells assembly?
It is not difficult to buy the 156x156mm high efficiency poly solar cells assembly,but the only concern would be the quality.
Q:How many types of solar cells are now being used in real life?
Many many types.
Q:Can the 156x156mm high efficiency single crystal cells assembly function better compared to the traditional one?
The reason why it is functioning better is because of its h igh power large area silicon solar cell.
Q:What are the short-circuit currents of solar cells affected by the factors?
Silicon cell: the life of the minority after the diffusion, silicon impurity content, silicon chip resistivity, cashmere suede, PE anti-reflective film anti-reflective effect, the front gate line printing and so on affect the short-circuit current.
Q:What can be used as the materials for solar cells?
The thin-film absorbers
