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:Is the Photovoltaic cell panel good to save the energy?
Yes, after being used and tested for years in the market, the photovoltaic cell panel is known to be very good to save energy.
Q:Is it possible to learn how to make solar cells by yourself?
Are you good at doing experiments? If you are, try it as many times as you can, then you will be finally be an expert!
Q:Which one is better on the solar cells panel? The Monocrystal Solar Energy Cell or photovoltaic cell?
It depends on where you put the solar cells, and what will you use them for. But I do think photovoltaic cell is better.
Q:What can be used as the materials for solar cells?
As far as I know, silicon is used as the material for solar cells.
Q:Where can I find more information about the work process of solar cells
From your teachers at school.
Q:What is the best way to deal with surplus solar cells abandoned after burning?
This is a very commonly mentioned topic related to environmental protection, because the abandoned solar cells have battery surplus could be very bad for our environment. Scientiests are dicussing ways to deal with that but there is still not a good solution.
Q:Are there any books in the market t about solar cells and their applications?
The solar was used in the SwissTech Convention Center.
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:How can I buy the solar cells wholesale ?
The wholesale price for solar cell is based on your quantities of the solar cells you want to buy from the manufacturers. The more you order, the cheaper wholesale price you would get.
Q:My son is very interested in solar cells recently, and keeps asking me about the structure of a solar cell. Can anybody help me answer that question?
Here is what I found from my chemistry teacher: The basic component of a solar cell is pure silicon, which is not pure in its natural state.
