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:What is the accurate explanation for the sun solar cell power system? How does it work?
The sun solar cells power system is the newly developed technology which can change the sunlight power into the energy used in our work and life.
Q:How do solar cells perform in areas with high levels of wildfire smoke?
Solar cells can experience a decrease in performance in areas with high levels of wildfire smoke due to reduced sunlight reaching the surface. The smoke particles in the air can scatter and absorb sunlight, resulting in lower energy production. Additionally, the deposition of ash and soot on the solar panels can further reduce their efficiency. Regular cleaning and maintenance can help mitigate these effects to some extent.
Q:How do solar cells perform in high altitude regions?
Solar cells perform more efficiently in high altitude regions due to several factors. Firstly, high altitudes often have less air pollution, which means there are fewer particles in the air that can block or scatter sunlight. This allows solar cells to receive more direct sunlight, resulting in increased energy production. Additionally, solar cells operate more efficiently at lower temperatures, and high altitudes generally have cooler temperatures compared to lower elevations. Cooler temperatures help to reduce heat-related losses and improve the overall performance of solar cells. Therefore, solar cells in high altitude regions tend to generate more electricity and have higher conversion rates.
Q:What is the usage of solar cells?
Solar cells can be used in many different places, such as the power supply factories.
Q:How do solar cells contribute to reducing greenhouse gas emissions?
Solar cells contribute to reducing greenhouse gas emissions by generating electricity from sunlight, a renewable and clean source of energy. By harnessing solar power, solar cells eliminate the need for conventional fossil fuel-based electricity generation methods, such as burning coal or natural gas, which release large amounts of greenhouse gases into the atmosphere. Therefore, the widespread adoption of solar cells helps decrease our dependence on fossil fuels, mitigates climate change, and contributes to a more sustainable future.
Q:How long does it take for solar cells to pay for themselves?
The payback period for solar cells can vary widely depending on factors such as the initial cost of the system, local energy prices, available incentives, and the amount of electricity generated. On average, it can take anywhere between 5 to 15 years for solar cells to pay for themselves through energy savings and potential government incentives.
Q:What is the role of tracking systems in solar cell installations?
The role of tracking systems in solar cell installations is to optimize the amount of sunlight that reaches the solar panels throughout the day. These systems continuously monitor the position of the sun and adjust the orientation and tilt of the panels accordingly. By tracking the sun's movement, the panels can capture more sunlight and generate higher energy output, increasing the overall efficiency of the solar cell installation.
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
The principle of solar cells is quite difficult to understand.
Q:How much maintenance do solar cells require?
Solar cells require very little maintenance. They are designed to be durable and can last for several decades with minimal upkeep. Routine maintenance typically involves cleaning the surface of the solar panels to ensure optimal sunlight absorption and occasionally checking for any damage or debris. Overall, solar cells are a low-maintenance energy solution.
Q:What is the difference between solar cells and solar panels?
Solar cells and solar panels are closely related but have some key differences. A solar cell refers to a single unit that converts sunlight into electricity through the photovoltaic effect. It is the basic building block of a solar panel. On the other hand, a solar panel, also known as a photovoltaic module, is made up of multiple interconnected solar cells. The purpose of a solar panel is to harness a larger amount of sunlight and generate a higher output of electricity. In summary, while a solar cell is the individual component that directly converts sunlight into electricity, a solar panel is a collection of interconnected solar cells that work together to produce a higher power output.
