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 of 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.

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:How about the solar cell 156mm Mono-Crystalline?
It is the kind of solar cells That is unobstructed sunlight of the outdoor environment and it can be Operated under the temperature between -20 ℃ to +85 ℃
Q:How many solar cells are there in a solar panel?
Maybe 15 or more.
Q:Have you ever been to a solar cell power generation station?
Of course, I've been there at least 3 times.
Q:Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?
To make is simple first, the numbers you saw such as 125mm, 156mm, 152mm, refers to the diameter of the silicon wafer.
Q:How to generate solar cells, the principle of PN junction
Solar energy is an inexhaustible renewable energy source for human beings, and it is clean energy and does not produce any environmental pollution. In the effective use of solar energy; solar energy photoelectric utilization is the fastest growing and most dynamic in recent years
Q:How long does it take to make a solar cell?
It is now mass produced, so it doesn't take long to make it in the factory.
Q:Monocrystalline silicon and polycrystalline silicon cell in the appearance of what is the difference?
There is a part of the area filled with dissatisfaction, and polysilicon solar cells are square, there is no such problem, so the efficiency of the solar cell components is almost the same. In addition, due to the two solar cell materials manufacturing process is not the same, polysilicon solar cell manufacturing process consumption of energy than monocrystalline silicon solar cells about 30%, so polysilicon solar cells
Q:What are the 3 things you need to know before you start to make solar cells?
Firstly, coating the glass plates, secondly, assembling the solar cell, thirdly, activating and testing the solar cell.
Q:PV: the battery to the battery charge problem
I use the BUCK circuit, controlled by the microcontroller, the circuit is not too difficult, are ready, but the understanding of BUCK problems. See a lot of books are written on the battery can be constant pressure charging, feeling can not understand. Now I think they are probably wrong, the voltage across the battery in the BUCK circuit is out of control.
Q:Solar water heater plate can be directly converted into electrical energy?
Solar panels: solar panels are the core of the solar power system and the highest value part of the solar power generation system, which transforms the sun's radiant power into electricity or stores it in a battery or drives the load The quality and cost of solar panels will directly determine the quality and cost of the entire system;
