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.

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 typical size and weight of a solar cell?
The typical size of a solar cell ranges from a few square centimeters to several square meters, while the weight can vary from a few grams to a few kilograms, depending on the technology and application.
Q:Can solar cells be used in underwater applications?
Yes, solar cells can be used in underwater applications. However, special considerations need to be taken, such as using waterproof and corrosion-resistant materials, optimizing the design for low light conditions, and addressing the challenges of transmitting power and data underwater.
Q:Can solar cells be used for off-grid power supply?
Yes, solar cells can be used for off-grid power supply. Solar cells, also known as photovoltaic cells, convert sunlight directly into electricity. This makes them an excellent choice for powering off-grid locations where access to traditional power sources may be limited or unavailable. Solar panels can be installed in remote areas to generate electricity, providing a sustainable and renewable energy solution for off-grid power supply.
Q:Can solar cells be damaged by hail or other weather events?
Yes, solar cells can be damaged by hail or other severe weather events. Hailstones can potentially crack or shatter the surface of the solar panels, affecting their efficiency and functionality. Similarly, extreme weather events like hurricanes or heavy storms can cause physical damage by dislodging or breaking the panels, leading to a decrease in their performance. It is important to ensure proper installation and maintenance to minimize the risk of weather-related damage to solar cells.
Q:Can solar cells be used in water pumps?
Yes, solar cells can be used in water pumps. Solar-powered water pumps utilize solar panels to convert sunlight into electricity, which can then power the pump to draw water from a well or other water sources. This renewable energy solution is particularly beneficial in remote areas with limited access to electricity grids or where conventional power sources are expensive or unreliable.
Q:What is the expected degradation rate of a solar cell?
The expected degradation rate of a solar cell can vary depending on various factors such as the type of solar cell, the quality of materials used, the environmental conditions, and the maintenance practices. On average, however, most solar cells experience a degradation rate of around 0.5% to 1% per year. This means that the efficiency of the solar cell decreases by this percentage over time. Proper maintenance and regular cleaning can help mitigate degradation and extend the lifespan of a solar cell.
Q:Can solar cells be used in industrial applications?
Yes, solar cells can be used in industrial applications. They are increasingly being integrated into various industrial processes and systems, such as powering machinery, providing electricity for lighting, heating and cooling, as well as supplying energy for remote industrial sites. The use of solar cells in industrial applications helps reduce reliance on conventional energy sources, lowers operating costs, and contributes to a more sustainable and environmentally friendly industrial sector.
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:Briefly explain why solar cells are made into components
The main photovoltaic material is the crystalline silicon material (including polysilicon and monocrystalline silicon), this material is high hardness, brittleness, uneven force easily brittle, exposed to the air easily oxidized, and the use of the process can not
Q:Can solar cells be used in off-grid systems?
Yes, solar cells can be used in off-grid systems. Off-grid systems typically rely on renewable energy sources, and solar cells are an ideal choice for generating electricity in such systems. Solar cells convert sunlight into electricity, which can be stored in batteries for use when the sun is not shining. This allows off-grid systems to power various appliances and devices without the need for a connection to the traditional power grid.
