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 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, or multicrystalline silicon (multi-Si) cells are made from cast square ingots—large blocks of molten silicon carefully cooled and solidified. They consist of small crystals giving the material its typical metal flake effect. Polysilicon cells are the most common type used in photovoltaics and are less expensive, yet less efficient than those made from monocrystalline silicon.

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:

1.     Tire-1 Solar Cells’ Manufacturer Quality Guarantee. With a complete and sophisticated quality government system, our Quality Management have arrived world’s leading place. Customer can receive Tire-1 Cells Maker’s Quality Standard Products.

2.     Trusted Warranty. We can supply trusted after-sales service to our customer. If our cells are found not in conformity to the specification of manufacturer, or should the inspected quantity found in shortage, or should the packing found damaged, the buyer has the right to claim to the seller. The claim, if any, should be presented to seller within 30 days after cargo's arrival date to the port, together with related inspection report and photos issued and provided by a reputable independent surveyor such as SGS.

3.     World’s Leading Manufacturer Equipment. We imported the newest and leading production equipment from abroad. Advanced equipment can guarantee the stable quality of cells. Auto production line can also save labor cost which will further cut our production cost.

4.     Bulk supply: With the production capacity of 500MW, we can produce large quantity every month. This can satisfy most customer requirement.

 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:Solar cells and the difference between ordinary batteries. Why is the solar cell is converted into electrical energy, zinc battery is what is converted into chemical energy
Ordinary batteries have a certain life, can not be stored for too long, or the power will slowly run out of solar cells do not exist chemical failure, can be long-term preservation.
Q:What diode does the solar panel use?
Species, then the impact of ordinary diode voltage drop will be relatively large, but if the voltage is relatively high, then 0.3V gap relative impact is relatively small.
Q:Can the 156x156mm high efficiency single crystal cells assembly function better compared to the traditional one?
The reason why it is functioning better is because of its h igh power large area silicon solar cell.
Q:What is Solar Cell Technology?
A newly-developed technology which can help us get a lot energy from the sunlight.
Q:Where and how can we find the best solar cells suppliers?
I used to be a solar cells business dealer in the European market for over ten years, and I did not only use the internet to find the supplier, but also go to a lot solar cells industrial exhibition fairs.
Q:Can the solar powered cells really work better than the normal cells?
Because of the different ways of generating the power, the solar powered cells definitely better than the normal cells in the modern world.
Q:How long does it take to make a solar cell?
If you decide to make it by yourself, it will take you very long.
Q:Is silicon-based solar cells and silicon-based thin-film solar cells the same?
General silicon-based solar cells refer to monocrystalline silicon and polycrystalline silicon solar cells, while silicon-based thin-film solar cells are similar to sunpower producing that type of battery that can be made into curved components.
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:Where can I buy solar cells on sale but still good quality ?
There are many ways you can buy solar cells, online, like Amazon.com. Alibaba.com, or local agent who sells more than 10 brands of solar cells produced in different countries.
