Polycrystalline Silicon 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 ap-n 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 clientsmay help you sincerely

What price for each watt?

It depends on the efficiency of the solar cell, quantity, delivery date and payment terms.

How 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.

Can 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.

What is your warranty of solar cell?

Space solar power station in space means that solar energy will be converted into electrical energy, transmission by wireless energy transmission to the ground, or simply to reflect sunlight to the ground, on the ground power systems. In the present research the United States, Russia, Japan and other countries. Its development prospects are very promising.
Characteristics of Space Solar Cells
The greatest feature of this system is green. Collect solar energy in space, the impact on the global environment is small and completely dependent on the earth's resources.
To build solar power plants in the ground, due to the influence of atmospheric absorption and scattering effects of sunlight to the ground after strong attenuation to 1.0 kW / square meter; and if the establishment of the space solar power station, the light intensity of 1.353 kilowatts / square meters, and 99% time of day, and therefore has a high power generation efficiency.
While the power generation efficiency space solar power plant is far above the ground. Continuously receiving solar energy from space cannot be affected by the season, such as diurnal variation, receiving high energy density, it is 7-12 times the average light power of the ground; while stably transmit energy to the ground, basically from the atmosphere.
Space Station on the technical principles has been no problem. Solar panels widely used in satellites, but in recent years, the power generation efficiency of solar cells, the conversion efficiency of microwave technology has made great progress, has laid a good foundation for the development of the system. But to achieve the industry standard applications, the requirements for power generation will be high, at least megawatts, G watt magnitude; solar panels may use to calculate the square.

 


Q: Can solar cells be used in mountainous regions?
Yes, solar cells can be used in mountainous regions. In fact, mountainous regions can often be advantageous for solar energy generation due to the higher altitude and reduced air pollution, which can result in increased solar radiation. However, the installation of solar panels may require careful consideration of factors such as slope, orientation, and potential shading from surrounding mountains or trees.
Q: Do solar cells work in cloudy weather?
Yes, solar cells can still generate electricity in cloudy weather, although their efficiency may be reduced compared to clear, sunny conditions.
Q: How are solar cells connected in a photovoltaic system?
Solar cells are connected in a photovoltaic system in series or parallel configurations to generate the desired voltage and current output.
Q: What is the environmental impact of manufacturing solar cells?
The environmental impact of manufacturing solar cells primarily stems from the production of raw materials, energy consumption during manufacturing processes, and waste generation. The extraction and processing of minerals, such as silicon, cadmium, and silver, required for solar cell production can result in habitat destruction, water and air pollution, and carbon emissions. Additionally, the energy-intensive manufacturing processes, including refining, purification, and crystallization, contribute to greenhouse gas emissions. However, it is worth noting that compared to conventional energy sources, the overall environmental impact of solar cell manufacturing is relatively low and can be offset by the clean energy produced throughout their lifecycle.
Q: Can solar cells be used on boats?
Yes, solar cells can be used on boats. They are a popular and sustainable source of energy for powering various systems on boats, including lighting, navigation equipment, and charging batteries. Solar panels can be easily installed on the deck or roof of a boat to harness sunlight and convert it into electricity, reducing the reliance on traditional fuel sources and offering a clean and renewable energy solution.
Q: What happens to excess electricity generated by solar cells?
Excess electricity generated by solar cells can be stored in batteries for later use, fed into the power grid to offset energy consumption, or utilized to power other devices or systems within the property.
Q: Can solar cells be used in disaster relief efforts?
Yes, solar cells can be used in disaster relief efforts. They are a reliable and sustainable source of energy that can provide electricity in areas affected by natural disasters, where power grids may be damaged or non-existent. Solar cells can be used to power emergency lighting, communication systems, medical equipment, and water purification systems, among other essential needs. Additionally, solar energy can be harnessed to charge mobile devices and provide a means of communication and access to information during these critical times. Overall, solar cells are a valuable tool in disaster relief efforts, offering a clean and renewable energy solution to support affected communities.
Q: Can solar cells be used to power remote sensing devices?
Yes, solar cells can be used to power remote sensing devices. Solar cells convert sunlight into electrical energy, which can be stored in batteries to power remote sensing devices in areas where grid power is not available. This makes solar cells an efficient and sustainable solution for powering remote sensing devices.
Q: Can solar cells be used in powering remote weather stations?
Yes, solar cells can be used to power remote weather stations. Solar cells are a sustainable and efficient way to generate electricity, making them ideal for remote locations where access to grid power is limited. They can provide a reliable source of power for weather stations, allowing them to operate continuously and gather data even in remote areas.
Q: How does a solar cell raise industrial efficiency?
A solar cell provides long-lasting electricity which is vital in factories, that's how it raises efficiency.
