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:How do solar cells perform in regions with high levels of dust and sandstorms?
Solar cells may experience decreased performance in regions with high levels of dust and sandstorms. The accumulation of dust particles on the surface of solar panels can reduce their efficiency by blocking sunlight and reducing the amount of energy they can generate. Regular cleaning and maintenance of solar panels are essential in such environments to ensure optimal performance. Additionally, advancements in solar panel technology, such as anti-soiling coatings, are being developed to mitigate the impact of dust and sandstorms on solar cell performance.
Q:How do solar cells handle high winds or hurricanes?
Solar cells are designed to withstand high winds and hurricanes due to their robust construction and installation techniques. The panels are securely anchored to rooftops or mounted on sturdy frames, ensuring they can withstand strong winds. Additionally, solar panels are tested and rated for wind resistance, with most systems being rated to withstand wind speeds of up to 140 miles per hour. Therefore, solar cells are designed to handle high winds and hurricanes with minimal damage or risk of detachment.
Q:Can solar cells be used in satellites?
Yes, solar cells can be and are commonly used in satellites as they provide a reliable and efficient source of power by converting sunlight into electricity.
Q:Can solar cells be used in schools or educational institutions?
Yes, solar cells can definitely be used in schools or educational institutions. They provide a practical and hands-on way to teach students about renewable energy sources, sustainability, and environmental stewardship. Installing solar cells in schools can also help reduce electricity costs and promote energy efficiency, making it a beneficial investment for educational institutions.
Q:Are there any books in the market t about solar cells and their applications?
The solar cell is used in the commercial and industrial industry very often.
Q:Can solar cells be used to power medical devices or implants?
Yes, solar cells can be used to power medical devices or implants. They can provide a renewable and sustainable source of energy for various medical applications, including implants such as pacemakers, insulin pumps, and hearing aids. By utilizing solar energy, these devices can operate without relying on traditional batteries or frequent replacements, offering patients greater convenience and reducing the need for invasive procedures.
Q:Can solar cells be used in cloudy or rainy weather?
Yes, solar cells can still generate electricity in cloudy or rainy weather, although their efficiency may be reduced compared to sunny conditions.
Q:Does solar cell cost less than the other power generation technology?
It cost more to build the solar cell because it requires more research and technology, but it won't cost much in long term.
Q:Can solar cells be used underwater?
No, solar cells cannot be used underwater as they rely on sunlight to generate electricity. Water blocks sunlight and prevents the solar cells from functioning effectively.
Q:Can solar cells generate power at night?
No, solar cells cannot generate power at night as they rely on sunlight to produce electricity.
