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:Briefly explain why solar cells are made into components
The electrical performance parameters of solar cells are: voltage, current, capacity, type, charging rate and so on. The voltage parameter of the battery refers to the operating voltage of the battery, that is, the voltage that can be supplied to the device. Current, refers to the maximum discharge current of the battery. Capacity, refers to the total discharge power of the battery, with An / hour (A / H) said.
Q:Solar cell life for several years
Photoelectric effect of the work of thin film solar cells as the mainstream, and the implementation of photochemical effects of solar cells is still in the embryonic stage.
Q:How does the photovoltaic cells work?
Photovoltaic solar cells are the thin silicon chips that transform the sunlight into electricity in a scientfic way.
Q:Is solar cell technology very developed and v applied to life a lot?
Yes as far as I know.
Q:Which Solar Panel Type is best? Polycrystalline panel or PV Module Monocrystalline Solar cell panel, or thin film?
The Monocrystalline silicon solar panels requires less space to operate, so it is one of the best if you don't have a huge space to install it.
Q:Are there any books in the market t about solar cells and their applications?
You can try to search online about the application of solar cells.
Q:The history of solar cells
Was first applied to cardiac pacemakers. As the lithium battery self-discharge rate is very low, the discharge voltage is gentle. Making the pacemaker implanted in the human body as long as possible. Lithium batteries are generally higher than the nominal voltage of 3.0 volts, more suitable for integrated circuit power. Manganese dioxide batteries, widely used in computers, calculators
Q:Where can I buy solar cells on sale but still good quality ?
Good solar cell sellers can get the best solar cells with highest quality as they have very strict quality control from material-during manufacturing-assemble-package; and they also check and test the structure strictly to ensure the whole solar mounting system can work under extreme weather condition;
Q:I bought a new poly solar cells, and the test result of the conversion efficiency is 16.8%, is it lower than usual?
If the solar cells have been used for over 5 years or more, the conversion efficiency may become lower.
Q:Where can I get the most accurate information about solar cells?
Maybe your teacher can give you some suggestions.
