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:The advantages and effects of solar energy
There are transportation problems, especially in the underdeveloped rural areas, islands and remote areas more valuable value.Third: solar energy is a clean energy in the development and utilization, will not produce waste, waste water, waste gas, no noise
Q:How about the solar cell 156mm Mono-Crystalline?
It is difficult to explain, but the measurement usually doesn't matter, because only the materials matters most for the solar cells.
Q:What is the solar cells market in China?
The solar cells industries has developed over the past 10 years, which means there are now a lot of competition in this industry. However, there are still some market margin because the solar cells industry needs better quality and high technology to be really good.
Q:The difference between a fuel cell and a solar cell
At present fuel cell system fuel - power conversion efficiency of 45% to 60%, while the thermal power and nuclear power efficiency of about 30% to 40%. (2) Hazardous gases SOx, NOx and noise emissions are low CO2 emissions are greatly reduced due to high energy conversion efficiency, no mechanical vibration.
Q:Do you believe you can make a solar cell by using kitchenware?
Really? Can you show me how?
Q:How is the solar panel and the battery connected?
Solar cells and battery connection, it is best to use a photovoltaic charging controller, which can control the output voltage of solar cells can protect the battery is not overcharge, but also at night when the solar cell does not generate electricity, to prevent the battery power back
Q:Can a solar cell be used in commercial buildings?
My apartment used solar cells as the main power supply .
Q:What is the solar cell?
The type of solar cells can be divided according to the materials used: silicon solar cells, solar cells and organic semiconductor system of solar cells.
Q:Silicon solar cell power generation principle
The expected efficiency of the theory is 24% .As the semiconductor PN junction device in the sun under the photoelectric conversion efficiency of the highest, so these photovoltaic devices are usually referred to as solar cells, also known as photovoltaic cells or solar cells.
Q:Where and how can I find more information of Photovoltaic Cells Solar Panels? Can anybody share more about that?
Photovoltaic cells are considered to be one of the most reliable sun power generation materials and very easy to to maintain.
