FAQ:

1.Price per watt?

It depends on the quantity, delivery date and payment terms.

2.Parameter of the module?

We have different series of panels in different output, both c-si and a-si. please take the specification sheet for your reference.

3.Can you provide the peripheral products of the solar panels, such as the battery, controller etc.?

We have two companies(CNBM International & CNBM engineering Co.) with different approaches. We can supply not only the solar module but also Solar Cells, off grid solar system, even service with on grid plant.

4.Warranty policy?

Our product performance guarantees for 25 years

• 12 years guarantee for workmanship

• Timeliness of delivery

• Quality Products certified (TÜV, UL, CE, ISO)

5.Lead time?

In 3 days after purchasing, we will arrange the factory delivery ASAP. The specific time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.


Q: Are solar panels safe?
Yes, solar panels are safe. They are designed and installed with safety measures in place to ensure their proper functioning and to minimize any potential risks.
Q: Can solar panels be used in conjunction with wind turbines?
Yes, solar panels can indeed be used in conjunction with wind turbines. This combination of renewable energy sources can provide a more reliable and consistent power supply, as wind and solar resources often complement each other. During periods of low sunlight, wind turbines can generate electricity, and during calm periods with low wind, solar panels can continue to produce power. Integrating both technologies can enhance the overall efficiency and effectiveness of a renewable energy system.
Q: How much energy can be generated from a solar panel on a clear, bright summer's day for example?
Well, the maximum amount of energy you can receive with 00 percent efficiency is kilowatt per square meter. This is the energy that hits the Earth's surface. The best commercially available panels are 20-30 percent efficient. Cutting edge technology has gotten this percentage up to 50 percent, but you can't buy these for your home. If you're curious about efficiency, check out a panel's dimensions, find the area in square meters, and use that along with its Watts (divide by 000 to get kilowatts) to get your answer.
Q: If you want to instal solar panels...how often do you have to replace them?
One of the major solar panel manufacturers just upped their warranty period to 30 years for 90% of their rated output because the panels just keep working without losing efficiency. Of course if a large hail storm comes by you might have to replace them a little earlier..
Q: I need to know how do solar panels work. I need to know what are they made of.
The term solar panel is best applied to a flat solar thermal collector, such as a solar hot water or air panel used to heat water, air, or otherwise collect solar thermal energy. But 'solar panel' may also refer to a photovoltaic module which is an assembly of solar cells used to generate electricity. In all cases, the panels are typically flat, and are available in various heights and widths.
Q: Can solar panels be installed on a convention center or event venue?
Yes, solar panels can be installed on a convention center or event venue. In fact, many convention centers and event venues are increasingly adopting solar energy solutions to reduce their carbon footprint and lower energy costs. The large roof spaces available in these venues often make them ideal for solar panel installations, allowing them to generate clean and renewable energy.
Q: lately i have been interested in solar power. i own my own home and in Texas it's HOT, so my A/C is always on and that light bill is like $300.00 a month. i was looking at other light companies but then i remembered that there are the so called solar power but i dont knowknow to start or how it would work to power the a/c machine...pls help
I live near a community in Mexico where hey have no power. It is in the desert and is perfect for solar because they only have 3-4 in. rain a year. It is on the beach so many wealthy have homes there that are on solar systems. I have helped my friends set up and work on many of them. Solar systems WILL NOT normally support air conditioning unless you install a gas powered ammonia or lithium Bromide system. In these systems the refrigeration cycle heat is supplied by the gas instead of a compressor, so the only electrical power is a small circulation pump which will not drain batteries fast. These are a problem in some areas because not many people know how to maintain and repair this type of system. Some of my friends claim they can run a very small one room AC on their solar systems just to at least have a place to sleep that is cool. Others say it is questionable. Please understand these systems are not cheap. Most of them paid $20,000 - $35,000 and even more if you use the ammonia cycle AC. The systems usually have 0-2 panels, a 0-5 KW gas generator, and large bank of large batteries like ones you use in a golf cart or bigger. I also must apologize to all the environmentalists for the inconvenient truth.
Q: Could you have a solar panel in space that would transmit electricity remotely? Maybe have some kind of receiving antenna to pick up the energy? Perhaps there could be a string of them orbiting the Earth?Why wouldn't that work?
Wireless okorder . May be in future research will give a means to harness solar energy from space.
Q: are there solar panel that work without the sun?
No. Solar literally means Sun. But...scientists are working on a panel that can absorb energy after the sun has set. It may be years until we see any commercial success.
Q: Can solar panels be used in areas with high levels of seismic activity?
Yes, solar panels can be used in areas with high levels of seismic activity. However, it is crucial to ensure that they are designed and installed to withstand earthquakes and other seismic events. Specialized mounting systems and structural reinforcements can be employed to enhance the resilience of solar panels in such areas, reducing the risk of damage or failure during seismic activity.
