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:What is Solar Cell Technology?
A technology which converts the sun power into the electricity.
Q:How to get high voltage, high current output of solar cells
Series can increase the output voltage, parallel can provide output current. Using a series parallel method to achieve, for example: need 220 volts 10 amps.
Q:Why should the solar cells be laserized?
Extended reading: Through the practice of testing and manufacturers, Tuopu photoelectric laser etching technology summary, the results of the current solar photovoltaic industry using laser etching scribing technology P1 level using narrow pulse infrared nano-laser is the most ideal,
Q:What are the tin bands, sinks and interconnections used on solar modules, and what are the solar cells used in the solar cells?
Light incident on the side of the general agreement for the positive, ordinary p-type battery front pn knot is the final need to use, and the back is called back knot.
Q:I bought a new poly solar cells, and the test result of the conversion efficiency is 16.8%, is it lower than usual?
Since you mentioned that your poly solar cells is a newly bought one, I strongly recommend you to ask your supplier.
Q:What is the best sales solution for solar power cells?
I highly recommend you to put your solar power cells for sales on the B2B website, such as alibaba.com in China. Because in this way, your product can be seen by many buyers.
Q:Can a solar cell be used in commercial buildings?
My apartment used solar cells as the main power supply .
Q:How's the feedback of using 260 watt photovoltaic solar panel? Anybody ever used that?
The one I am using is up to 19% efficiency. It can be used for 24V home power generation system or grid connected.
