 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 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:I bought a new poly solar cells, and the test result of the conversion efficiency is 16.8%, is it lower than usual?
If the solar cells have been used for over 5 years or more, the conversion efficiency may become lower.
Q:Are solar cells durable?
Yes, solar cells are generally durable. They are designed to withstand harsh weather conditions such as extreme temperatures, rain, and snow. Additionally, most solar cells come with a warranty that guarantees their performance for a certain period, indicating their durability. However, like any technology, the lifespan of solar cells can vary depending on the quality of the materials used and how well they are maintained.
Q:How do solar cells handle electromagnetic interference?
Solar cells are typically designed to be resistant to electromagnetic interference by incorporating shielding and filtering techniques. These measures help to minimize the impact of electromagnetic waves from external sources, ensuring that the solar cells continue to operate efficiently and produce electricity without interference.
Q:Can solar cells be used in cloudy or rainy weather?
Yes, solar cells can still be used in cloudy or rainy weather, although their efficiency will be reduced. While solar cells generate less electricity under such conditions due to reduced sunlight intensity, they can still produce some power. Additionally, advancements in solar technology have improved the ability of solar cells to capture diffused and indirect sunlight, making them more viable in less optimal weather conditions.
Q:Can solar cells be used to power electric fences?
Yes, solar cells can be used to power electric fences. Solar cells convert sunlight into electricity, which can then be stored in batteries or used directly to power electric devices such as electric fences. This allows for a sustainable and reliable source of power, especially in remote areas where grid connection may not be feasible.
Q:Can solar cells be used for powering remote weather monitoring stations?
Yes, solar cells can be used for powering remote weather monitoring stations. Solar cells, also known as photovoltaic cells, convert sunlight into electricity, which can be used to power various devices and systems. Remote weather monitoring stations often require a consistent and reliable source of power, especially in locations where access to the electrical grid is limited or non-existent. Solar cells provide a sustainable and environmentally-friendly solution for these stations by harnessing sunlight to generate electricity, ensuring continuous operation of the monitoring equipment.
Q:I have a turnkey solar power project starting in 6 months, now we are searching the market in south China to find the best solar cells manufacturers. Any professional suggestion or recommendation?
How big is your project? Is it a turnkey project or something else? How about your budget? And the finishing date of the project? These are the questions you need to make sure you are clear about the answer.
Q:Friends are fuel cells are chemical energy into electricity, solar cells are converted into electricity into electricity I would like to know in addition to the structure and the conversion of different ways there are no other differences hope that the specific power of everyone
At present fuel cell system fuel - power conversion efficiency of 45% to 60%, while the thermal power and nuclear power efficiency of about 30% to 40%. (2) Hazardous gases SOx, NOx and noise emissions are low CO2 emissions are greatly reduced due to high energy conversion efficiency, no mechanical vibration.
Q:How do solar cells impact air pollution?
Solar cells have a significant positive impact on air pollution as they produce clean and renewable energy. By harnessing the power of the sun, solar cells reduce the need for fossil fuel combustion, which is a major source of air pollution. This means that the use of solar cells helps to decrease harmful emissions such as carbon dioxide, sulfur dioxide, and nitrogen oxides, leading to cleaner and healthier air.
Q:How do solar cells affect the value of a property?
Solar cells can significantly increase the value of a property. They not only provide a reliable and sustainable source of energy, but also reduce electricity bills, making the property more attractive to potential buyers. Additionally, solar panels are seen as a valuable asset that can generate income through net metering or feed-in tariffs, further increasing the property's value.
