Product Description:

PolyCrystalline Silicon Solar Cell 3 Bus Bars  Alkaline:

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 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.

PolyCrystalline Silicon Solar Cell 3 Bus Bars  Alkaline Advantage:

•  High efficiency and stable performance in photovoltaic conversion.
•  Advanced diffusion technique ensuring the homogeneity of energy conversion efficiency of the cell.
•  Advanced PECVD film forming, providing a dark blue silicon nitride anti-reflection film of homogenous color and attractive         appearance.
•  High quality metal paste for back surface and electrode, ensuring good conductivity, high pulling strength and ease of soldering.
•  High precision patterning using screen printing, ensuring accurate busbar location for ease with automatic soldering a laser cutting.

 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.

⑥ Can you do OEM for us?

Yes, we can.

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 fulfill two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity.
Q:How do people price solar cells? Is it based on a specific way of calculating the cost of solar cells?
According to our calculation the solar power cost around US$230 per square meter is it can generate 120W power supply per square meter.
Q:How can I describe solar cells in a simple way?
Solar cell is a specific battery.
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:Does the solar cell generate electricity in the absence of the sun, only in the case of strong lights or lasers? If you can achieve how much, and the same day?
Sunlight is a composite light, in which only the frequency is greater than the solar cell threshold photons can effectively stimulate the solar cell power generation.
Q:How much does a solar cell cost?
It's not easy to answer the question in a simple way, but an example is the residential solar systems are typically sized from 3 to 8kW and end up costing between $15,000 and $40,000.
Q:Solar panel resistance is changed with what
the lower the ambient temperature, the smaller the internal resistance of the battery, power generation The higher the effect; the other hand, the higher the temperature, the greater the internal resistance, the lower the efficiency.
Q:What is the most commonly used material for solar cells?
Anyone of these is the materials for making the solar cells: Crystalline silicon solar cell, silicon solar cell, silicon solar cell. Amorphous silicon cell: thin film solar cells, organic solar cells. Chemical dye cell plate: dye sensitized solar cell.
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.
