Solar Cells:

solar cells, when struck by photons of light from the sun, generates an electrical current which can then be used to power DC or AC electrical loads.
A solar cell is made of silicon. Computer chips are made of this same material. Basically, when light strikes the surface of a solar cell some of it is absorbed into the silicon. This light energy bumps the electrons loose and causes energy to flow

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.

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 difference between a solar cell and a solar panel?
A solar cell is a single unit that converts sunlight into electricity, while a solar panel is a collection of multiple solar cells connected together to generate a larger amount of electricity.
Q: How do solar cells impact water resources?
Solar cells have a positive impact on water resources as they do not require water for their operation, unlike traditional power plants that heavily rely on water for cooling purposes. This reduces the strain on water resources and helps in conserving them for other essential needs.
Q: Can solar cells be used in military vehicles?
Yes, solar cells can be used in military vehicles. They can provide an alternative source of energy to power various systems and equipment, reducing reliance on traditional fuel sources and enabling greater operational flexibility and sustainability. Additionally, solar cells can help extend the range and endurance of military vehicles in remote or austere environments where access to conventional fuel supplies may be limited.
Q: What kind of products can be considered as the solar cell products?
Many products are actually solar cell product, such as solar air conditioning, solar balloon, solar charger, solar dryer, solar cooker, etc.
Q: Can solar cells be used for powering hospitals?
Yes, solar cells can be used for powering hospitals. Solar energy can be converted into electricity by solar cells, and this electricity can be used to power various equipment and systems in hospitals, such as lighting, heating, cooling, and medical equipment. Solar power can provide a sustainable and reliable source of energy, especially in areas with limited access to the grid or unreliable power supply. Additionally, solar energy can help reduce hospitals' carbon footprint and operating costs in the long run.
Q: Can solar cells be used for powering wildlife tracking devices?
Yes, solar cells can be used for powering wildlife tracking devices. Solar panels can generate electricity from sunlight, which can then be stored in batteries to power tracking devices. This renewable energy solution is particularly useful for wildlife tracking as it eliminates the need for frequent battery replacements in remote areas.
Q: How do solar cells perform in areas with high levels of dust storms?
Solar cells can experience reduced performance in areas with high levels of dust storms. The accumulation of dust on the surface of solar panels can block sunlight and reduce the amount of energy they can generate. Regular cleaning and maintenance are necessary to ensure optimal performance in such regions.
Q: Can solar cells be used in powering remote weather stations?
Yes, solar cells can be used to power remote weather stations. Solar cells convert sunlight directly into electricity, making them an ideal and sustainable power source for remote locations where access to the electrical grid may be limited or non-existent. The solar panels can be installed on the weather station's roof or nearby, providing a constant supply of renewable energy to run the station's sensors, data loggers, and communication systems.
Q: Can solar cells be used in electric vehicle charging stations?
Yes, solar cells can be used in electric vehicle charging stations. Solar panels can generate electricity from sunlight, which can then be used to charge electric vehicles. This provides a sustainable and renewable energy source for charging stations, reducing dependency on traditional power grids and reducing carbon emissions.
Q: What is the role of bypass diodes in shading situations?
The role of bypass diodes in shading situations is to minimize the impact of shading on the overall performance of a solar panel. When a section of a solar panel is shaded, it can significantly reduce the current produced by that section, leading to a decrease in the overall power output. Bypass diodes are connected in parallel to each solar cell or a group of cells within a solar panel to provide an alternative path for the current to flow when shading occurs. This allows the shaded cells to be bypassed, preventing them from affecting the performance of the unshaded cells. By utilizing bypass diodes, the solar panel can maintain a higher level of efficiency and generate more power, even in shading situations.
