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 air pollution?
Solar cells perform less efficiently in regions with high levels of air pollution. Air pollution can block sunlight and reduce the amount of solar radiation reaching the solar cells, which in turn decreases their power output. Additionally, pollutants in the air can accumulate on the surface of solar panels, forming a layer of grime that further reduces their performance. Regular cleaning and maintenance of solar panels are necessary in such regions to ensure optimal functioning.
Q: Can solar cells be used to power remote transportation systems?
Yes, solar cells can be used to power remote transportation systems. Solar cells convert sunlight into electricity, which can be stored in batteries and used to power vehicles, such as electric cars, bikes, boats, or even small aircraft. This makes solar energy an environmentally friendly and sustainable option for powering transportation in remote areas where access to conventional power sources may be limited or non-existent.
Q: Can solar cells be used for powering water pumps?
Yes, solar cells can be used for powering water pumps. Solar-powered water pumping systems utilize photovoltaic cells to convert sunlight into electricity, which can then be used to power water pumps. These systems are environmentally friendly, cost-effective, and reliable, making them a popular choice for remote areas or locations where grid electricity is not available.
Q: Can solar cells be used in public charging stations for electric vehicles?
Yes, solar cells can be used in public charging stations for electric vehicles. Solar panels can generate electricity from sunlight and convert it into usable energy to charge electric vehicles, making them a sustainable and environmentally-friendly option for public charging infrastructure.
Q: Can solar cells be used to power medical devices?
Yes, solar cells can certainly be used to power medical devices. Solar-powered medical devices provide a sustainable and reliable source of energy, especially in remote or resource-limited areas where access to electricity may be limited. By harnessing the sun's energy, solar cells can power various medical devices such as diagnostic tools, monitoring systems, prosthetics, and even small surgical instruments. Solar power offers great potential for enhancing healthcare delivery and improving access to medical services globally.
Q: Can solar cells be used for powering communication systems?
Yes, solar cells can be used to power communication systems. Solar cells convert sunlight into electrical energy, which can then be used to power various electronic devices, including communication systems. This renewable source of energy is a sustainable and environmentally friendly option for powering communication systems, especially in remote or off-grid locations where access to traditional power sources may be limited.
Q: How does the size of a solar cell affect its performance?
The size of a solar cell directly affects its performance. Generally, larger solar cells can generate more electricity as they have a larger surface area to collect sunlight. This means they can absorb more photons and convert them into electrical energy. Additionally, larger solar cells tend to have lower resistance and better efficiency. However, larger cells also require more materials and are more expensive to produce. Therefore, the optimal size of a solar cell depends on various factors, including the available space, budget, and desired energy output.
Q: Can solar cells be used on road surfaces?
Yes, solar cells can be used on road surfaces. Solar road technology, also known as solar roadways, involves embedding solar panels into roadways to generate electricity. These solar panels are designed to withstand the weight of vehicles and can be used to power streetlights, traffic signals, and even electric vehicles. However, there are challenges to overcome, such as durability and cost-effectiveness, before widespread implementation can occur.
