Product Description:

 

Polycrystalline Silicon Solar Cells:

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 ap-n 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 clientsmay help you sincerely

What price for each watt?

It depends on the efficiency of the solar cell, quantity, delivery date and payment terms.

How 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.

Can 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.

What 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

• How 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.

 Can you do OEM for us?

Yes, we can.

 

 

Space solar power station in space means that solar energy will be converted into electrical energy, transmission by wireless energy transmission to the ground, or simply to reflect sunlight to the ground, on the ground power systems. In the present research the United States, Russia, Japan and other countries. Its development prospects are very promising.
Characteristics of Space Solar Cells
The greatest feature of this system is green. Collect solar energy in space, the impact on the global environment is small and completely dependent on the earth's resources.
To build solar power plants in the ground, due to the influence of atmospheric absorption and scattering effects of sunlight to the ground after strong attenuation to 1.0 kW / square meter; and if the establishment of the space solar power station, the light intensity of 1.353 kilowatts / square meters, and 99% time of day, and therefore has a high power generation efficiency.
While the power generation efficiency space solar power plant is far above the ground. Continuously receiving solar energy from space cannot be affected by the season, such as diurnal variation, receiving high energy density, it is 7-12 times the average light power of the ground; while stably transmit energy to the ground, basically from the atmosphere.
Space Station on the technical principles has been no problem. Solar panels widely used in satellites, but in recent years, the power generation efficiency of solar cells, the conversion efficiency of microwave technology has made great progress, has laid a good foundation for the development of the system. But to achieve the industry standard applications, the requirements for power generation will be high, at least megawatts, G watt magnitude; solar panels may use to calculate the square.

Q:How to get high voltage and high current output of solar cells?
The high current solar cells means the high voltage, if you want to achieve that goal, you need to put the circuits inside the solar cells in serial-parallel.
Q:What's the relationship between solar energy materials and solar cells?
Solar cells are made by the solar energy materials, which are actually basically silicon, a very developed and commonly used materials in the solar energy industry.
Q:Are there any books in the market t about solar cells and their applications?
There are a lot of resources about solar cells on line, and they are cheaper.
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:Is A grade better than the B grade when we buy the poly solar cells.
The poly solar cell with A grade means the sustainabilty and quality of the poly solar cells are better than the others.
Q:How much does a solar cell cost?
If you want to know how much a solar cell cost, it might take you longer time than you thought.
Q:The difference between a fuel cell and a solar cell
Fuel cell is very complex, involving chemical thermodynamics, electrochemistry, electrocatalysis, materials science, power systems and automatic control and other disciplines of the theory, with high power generation efficiency, less environmental pollution and so on.
Q:How many types of solar cells are now being used in real life?
3 kinds of solar cells, Silicon-based, organic, chemical.
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:Is the solar cells factory in China good and trustworthy?
5 years ago, I vistied a solar cell factory based in Inner Mongolia, and I was quite impressed by their professionalism, which gave me more confidence that they are better than we thought.
