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 PNjunction, 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 in countries with limited sunlight?
Yes, solar cells can still be used in countries with limited sunlight. While solar cells generate the most electricity under direct sunlight, they can still generate power even in cloudy or overcast conditions. Additionally, advancements in solar panel technology have made them more efficient in capturing diffuse sunlight, enabling their use in regions with limited sunlight.
Q:How do solar cells handle dust storms or sandstorms?
Solar cells are designed to withstand dust storms or sandstorms by incorporating protective measures. The surface of solar panels is typically made of tempered glass or other durable materials that can resist scratches or damage caused by blowing dust or sand. Additionally, the panels are often tilted or installed at an angle, allowing the wind to blow away any accumulated dust. Regular cleaning and maintenance are also carried out to ensure optimal performance in dusty conditions.
Q:What is the impact of solar cells on reducing electricity bills?
Solar cells have a significant impact on reducing electricity bills as they generate renewable energy from the sun, which can be used to power homes or businesses. By harnessing solar power, individuals can reduce their reliance on traditional electricity sources, resulting in lower monthly bills. Additionally, excess energy produced by solar cells can be fed back into the grid, earning credits or payments that further offset electricity costs. Overall, solar cells provide a sustainable and cost-effective solution for reducing electricity bills.
Q:How do solar cells perform in areas with high levels of pollen allergies?
Solar cells can generally perform well in areas with high levels of pollen allergies. While the presence of pollen might lead to some dust accumulation on the surface of the solar panels, it does not significantly impact their performance. Regular cleaning and maintenance can help ensure optimal efficiency of the solar cells, even in areas with high pollen levels.
Q:What is the role of anti-islanding devices in solar cell systems?
The role of anti-islanding devices in solar cell systems is to ensure the safety of utility workers by preventing the solar system from continuing to generate and supply electricity to the grid during a power outage. These devices detect when the grid connection is lost and immediately disconnect the solar system, preventing any potential harm or damage that could occur if electricity was still being fed into the grid.
Q:Can solar cells be used in data centers or server farms?
Yes, solar cells can be used in data centers or server farms. By installing solar panels, these facilities can generate renewable energy to power their operations. However, the feasibility and effectiveness of using solar cells in data centers may depend on factors such as the location, available space, energy demands, and storage capacity. Additionally, combining solar power with other energy sources and implementing energy-efficient practices can further optimize the sustainability of data centers and server farms.
Q:How does the solar cell work properly?
When sunlight enters a certain structure, the photons provide the energy to activate the semicondcutore to generate power.
Q:What is a multi-junction solar cell?
A multi-junction solar cell is a type of photovoltaic cell that consists of multiple layers of different semiconductor materials, each designed to absorb different wavelengths of sunlight. This allows the cell to convert a broader spectrum of light into electricity, resulting in higher efficiency and improved performance compared to traditional single-junction solar cells.
Q:My son is very interested in solar cells recently, and keeps asking me about the structure of a solar cell. Can anybody help me answer that question?
Here is what I found from my chemistry teacher: The basic component of a solar cell is pure silicon, which is not pure in its natural state.
Q:Are solar cells affected by shade?
Yes, solar cells are significantly affected by shade. Even a small amount of shade can cause a significant decrease in the power output of solar cells.
