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 electric vehicle charging?
Yes, solar cells can be used for electric vehicle charging. Solar panels can convert sunlight into electricity, which can then be used to charge electric vehicles. This process, known as solar charging, provides a sustainable and renewable energy source for EVs, reducing their dependence on the grid and decreasing carbon emissions.
Q: How are solar cells affected by temperature?
Solar cells are negatively affected by high temperatures as they experience a decrease in efficiency due to increased resistance and thermal losses. This is because higher temperatures lead to increased electron-hole recombination rates and decreased open-circuit voltage. However, low temperatures can also reduce solar cell performance due to decreased conductivity and increased series resistance.
Q: How do solar cells impact energy security?
Solar cells positively impact energy security by providing a reliable and sustainable source of electricity. As they generate power from sunlight, solar cells reduce dependence on fossil fuels, which are finite and contribute to environmental degradation. By diversifying the energy mix and promoting renewable energy adoption, solar cells enhance energy resilience and reduce vulnerability to price fluctuations and supply disruptions. Additionally, solar cells can be deployed in remote areas, increasing access to electricity and improving energy security for off-grid communities.
Q: What is the role of solar cells in powering electric fences?
The role of solar cells in powering electric fences is to convert sunlight into electrical energy, which is then stored in batteries. This stored energy is used to power the electric fence, providing a continuous and reliable source of electricity without the need for a traditional power source or connection to the electrical grid.
Q: Can solar cells be used in disaster relief efforts?
Yes, solar cells can be used in disaster relief efforts. Solar cells can provide a reliable source of clean and renewable energy, which is crucial during times of disaster when traditional power sources may be disrupted. Solar cells can power essential equipment and devices such as lighting, communication systems, medical equipment, and water purification systems, enabling relief workers to effectively respond to the needs of affected communities. Additionally, solar cells can be easily deployed and are not dependent on fuel supply or infrastructure, making them ideal for disaster-prone areas or remote locations.
Q: Can solar cells be used in large-scale power plants?
Yes, solar cells can be used in large-scale power plants. Large solar power plants, also known as solar farms or solar parks, employ thousands or even millions of solar panels or solar modules to convert sunlight into electricity. These power plants are capable of generating significant amounts of renewable energy, contributing to the overall energy grid and reducing dependence on fossil fuels.
Q: How do solar cells perform in regions with high levels of dust and sandstorms?
Solar cells can be affected by dust and sandstorms in regions with high levels of such conditions. The accumulation of dust particles on the surface of solar panels can reduce their efficiency by blocking sunlight and creating a layer of insulation. Regular maintenance, such as cleaning the panels to remove dust and debris, is crucial to ensure optimal performance. Additionally, advancements in solar panel designs, such as anti-reflective coatings and self-cleaning mechanisms, are being developed to mitigate the impact of dust and sandstorms on solar cell performance in these regions.
Q: Can solar cells be used for powering remote oil and gas pipelines?
Yes, solar cells can be used for powering remote oil and gas pipelines. Solar energy is a reliable and sustainable power source that can be harnessed in remote locations where traditional power infrastructure is limited or non-existent. Solar panels can be installed along the pipeline route to generate electricity, which can then be used to power various equipment, sensors, and monitoring systems necessary for the operation and maintenance of the pipelines. This reduces dependence on fossil fuels and provides an efficient and environmentally friendly solution for powering remote oil and gas pipelines.
Q: How is the solar cells factories working in China? Do they follow certain quality standards?
Yes, they follow the standard quality assurance protocol, and they are doing very well.
Q: What is the role of bypass diodes in shading situations?
The role of bypass diodes in shading situations is to minimize the impact of shading on the overall performance of a solar panel. When a section of a solar panel is shaded, it can significantly reduce the current produced by that section, leading to a decrease in the overall power output. Bypass diodes are connected in parallel to each solar cell or a group of cells within a solar panel to provide an alternative path for the current to flow when shading occurs. This allows the shaded cells to be bypassed, preventing them from affecting the performance of the unshaded cells. By utilizing bypass diodes, the solar panel can maintain a higher level of efficiency and generate more power, even in shading situations.
