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 on airplanes?
Yes, solar cells can be used on airplanes. In fact, solar-powered airplanes have been developed and successfully flown, demonstrating the feasibility of harnessing solar energy for aircraft propulsion. Solar cells can be integrated into the wings or body of the airplane to capture sunlight and convert it into electrical energy, reducing reliance on traditional fuel sources and making air travel more sustainable.
Q:How do solar cells perform in areas with limited space for installation?
Solar cells can still perform efficiently in areas with limited space for installation through the use of innovative technologies such as rooftop and building-integrated photovoltaics. These systems maximize the use of available space, allowing solar cells to generate electricity even in compact urban environments. Additionally, advancements in solar cell design and efficiency have made it possible to produce more power from smaller areas, further optimizing electricity generation in limited spaces.
Q:Can solar cells be used in water heating systems?
Yes, solar cells can be used in water heating systems. Solar water heating systems use solar thermal collectors, which consist of solar cells that convert sunlight into electricity. This electricity is then used to heat water, making it a sustainable and environmentally friendly option for water heating.
Q:How many solar cells are there in a solar panel?
The number of solar panels in an installation depends on a few factors, mainly the amount of physical space available for the installation.
Q:I know that solar cells are produced by DC and then converted into alternating current through the inverter, who explains why the solar cell is produced by DC?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region.
Q:What is the impact of snow accumulation on solar cells?
Snow accumulation on solar cells can have a negative impact on their performance and efficiency. The layer of snow covering the cells prevents sunlight from reaching the surface, reducing the electricity generation capacity. Additionally, the weight of the snow can potentially damage the cells or the supporting structure. Regular cleaning or tilting of the panels can minimize the impact and ensure optimal solar energy production.
Q:Can solar cells be used in underwater vehicles or submarines?
Yes, solar cells can be used in underwater vehicles or submarines as a source of renewable energy. However, their efficiency can be significantly reduced due to the limited amount of sunlight that reaches underwater. Nonetheless, advancements in solar cell technology are being made to optimize their performance in such environments.
Q:Whether the solar cell is light can produce electricity
A solar cell is a device that converts light energy directly into electrical energy by photoelectric effects or photochemical effects.
Q:What is the impact of maintenance and cleaning on solar cell performance?
Maintenance and cleaning have a significant impact on solar cell performance. Regular maintenance, such as monitoring and cleaning the panels, helps to remove dust, dirt, and other particles that can accumulate on the surface. This debris can reduce the amount of sunlight reaching the solar cells, thereby reducing their efficiency. Additionally, regular maintenance can identify and rectify any issues or defects in the system, ensuring optimal performance and longevity of the solar panels. Ultimately, proper maintenance and cleaning can maximize energy production and overall efficiency of solar cells.
Q:How do solar cells impact energy security?
Solar cells have a positive impact on energy security as they provide a clean and renewable source of electricity. By reducing dependence on fossil fuels, solar cells contribute to a more sustainable energy mix, decreasing the vulnerability to price fluctuations and supply disruptions associated with traditional energy sources. Additionally, solar cells can be installed at various scales, from individual households to large-scale power plants, enhancing energy diversification and decentralization, thus strengthening overall energy security.
