Product Description:

 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 PNjunction, 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.

Features:

1. High conversion efficiencies resulting in superior power output performance.

2. Outstanding power output even in low light or high temperature conditions

3. Optimized design for ease of soldering and lamination

4. Long-term stability, reliability and performance

5. Low breakage rate

6. Color uniformity


 Solar Cells 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.

Q:What is the pollution of solar cells?
cadmium mercury and other substances), zinc barrels if there is a paste in general electrolyte, its composition is mainly ammonium chloride and manganese dioxide, the middle of a carbon rod, the entire battery with asphalt seal cover, so that the battery Ingredients do not leak out. From this analysis we can see that the chemical battery mainly contains mercury, cadmium, lead, nickel, zinc, copper and so on heavy metals. As we all know, these heavy metals are harmful to the human body, such as: mercury: mercury can make the human body loose teeth, hair loss, finger jitter, nerve disorder
Q:Can the 156x156mm high efficiency single crystal cells assembly function better compared to the traditional one?
Yes, according to our research and development, we have statistics to show that the 156x156mm high efficiency single crystal cells assembly does function better compared to the traditional one.
Q:What is the solar cell production process
Will be inexhaustible sunshine into the benefit of mankind for the benefit of electricity, the core technology is the solar cell photoelectric conversion rate.
Q:Have you ever been to a solar cell power generation station?
Of course, I've been there at least 3 times.
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:What is sun cells technology?
The history of sun cell can be traced back to 1839, when the French physicist Becquerel Alexander-Edmond discovered the photovoltaic effect (effect Photovoltaic). Until 1883, the first selenium solar cell was made by the American scientist Fritts Charles.
Q:How long is the long cycle solar cell life?
There are discharge depth, such as each time the actual capacity of the battery only 30% of the battery, you can cycle more than 1500 times, that is, 4 years or so, but if every 80%, then only more than a year, 100% It is about 1 year it
Q:Is silicon-based solar cells and silicon-based thin-film solar cells the same?
Silicon-based solar cells include silicon-based thin-film solar cells, including monocrystalline silicon solar cells and polycrystalline silicon solar cells. Silicon-based thin-film solar cells can only be in the form of thin-film silicon-based solar cells.
Q:Anybody ever heard of solar roll flexible solar panel?
It could be a portable solar panel charges your digital camera, camcorder, GPS, and satellite phone. Expedition members no longer need to pack heavy batteries for their worldwide journeys.
Q:Does solar cell cost less than the other power generation technology?
Since it saves a lot of energy, and make less damage to the environment, it is considered less cost as a way to generate the power.
