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: Can solar cells be used for water desalination?
Yes, solar cells can be used for water desalination. Solar energy can be harnessed to power the desalination process, where the energy from the sun is converted into electricity by solar cells and used to separate the salt and impurities from seawater, making it suitable for drinking or agricultural purposes. This method, known as solar desalination, is an environmentally friendly and sustainable solution for addressing water scarcity in coastal areas.
Q: What is the difference between a monocrystalline and polycrystalline solar cell?
The main difference between a monocrystalline and polycrystalline solar cell lies in their composition and manufacturing process. Monocrystalline solar cells are made from a single, high-purity silicon crystal. This results in a uniform structure with a consistent and orderly arrangement of atoms. Monocrystalline cells are known for their high efficiency and sleek appearance, as they typically have a black or dark blue color. On the other hand, polycrystalline solar cells are made from multiple silicon crystals. These crystals are smaller and not as perfectly aligned, leading to a more random arrangement of atoms. Polycrystalline cells are usually recognizable by their bluish hue and a fragmented appearance. In terms of efficiency, monocrystalline solar cells tend to have a slightly higher efficiency rate compared to polycrystalline cells. However, recent advancements in technology have narrowed this efficiency gap, and polycrystalline cells are now approaching the efficiency levels of monocrystalline cells. Another difference is the cost. Monocrystalline solar panels are generally more expensive due to the higher purity of silicon required and the more complex manufacturing process. Polycrystalline panels, on the other hand, are more cost-effective and offer a lower price per watt. In summary, while monocrystalline solar cells have higher efficiency and a more uniform appearance, polycrystalline cells are more cost-effective and have made significant improvements in efficiency in recent years. The choice between the two ultimately depends on individual preferences, budget, and specific project requirements.
Q: Can solar cells be used to power irrigation systems?
Yes, solar cells can be used to power irrigation systems. Solar panels can convert sunlight into electricity, which can then be used to power pumps, motors, and other components of an irrigation system. This renewable energy source can provide a sustainable and cost-effective solution for powering irrigation systems, especially in remote or off-grid locations.
Q: Can solar cells be used for powering electric fences?
Yes, solar cells can be used for powering electric fences. Solar cells convert sunlight into electrical energy, which can be stored in batteries and used to power electric fences. This provides a sustainable and environmentally-friendly solution for powering fences in areas where access to grid electricity is limited or expensive.
Q: How do solar cells perform in different geographical locations?
Solar cells perform differently in different geographical locations due to variations in sunlight intensity and weather conditions. Generally, locations closer to the equator receive more sunlight and have higher solar energy potential, resulting in better solar cell performance. However, solar cells can still generate electricity in less sunny areas, albeit with reduced efficiency. Factors such as cloud cover, temperature, and air pollution can also affect their performance. Therefore, it is important to consider the specific geographical location and its unique characteristics when assessing the performance of solar cells.
Q: How do solar cells affect property value?
Solar cells can positively impact property value by increasing its market appeal and attractiveness to potential buyers. The presence of solar cells signifies energy efficiency, lower electricity costs, and environmental consciousness, which are all desirable qualities in a property. Additionally, solar cells can potentially generate income through net metering or selling excess energy back to the grid, further enhancing the value of the property.
Q: How do solar cells impact national energy policies?
Solar cells have a significant impact on national energy policies as they promote the diversification and decentralization of energy sources. By harnessing the power of the sun, solar cells contribute to the development of renewable energy and reduce reliance on fossil fuels. This, in turn, helps countries achieve their energy security goals, mitigate climate change, and enhance sustainability. Governments often incentivize the adoption of solar cells through policy measures such as feed-in tariffs, tax credits, and research funding, which further drive the growth of solar energy and shape national energy policies.
Q: How are solar cells used in calculators?
Solar cells are used in calculators to convert sunlight into electrical energy. This energy is then used to power the calculator, eliminating the need for batteries or other external power sources.
Q: What is the solar cell?
The type of solar cells can be divided according to the materials used: silicon solar cells, solar cells and organic semiconductor system of solar cells.
Q: Are solar cells environmentally friendly?
Yes, solar cells are environmentally friendly. They produce clean and renewable energy by harnessing sunlight, which reduces dependence on fossil fuels and lowers greenhouse gas emissions. Additionally, solar cells do not produce any air or water pollution during operation, making them a sustainable and eco-friendly energy source.
