Company Profile
China National Building Material (CNBM) Group Corporation
CNBM Solar photovoltaic (PV) Panel is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array. Monocrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon. Hence most c-Si panels have uncovered gaps at the four corners of the cells.
CNBM International Corporation is a professional solar panel manufacturer in China for CNBM brand . Silicon panel ( silicon module), as our main product, has high quality and good service. Our products are very popular in Europe, Australia, England, Middle East, Mexico, Argentina, Chili, Singapore and Africa.
Furthermore, our products have gained international authorized certificates like TUV, UL and CE.
China National Building Material (Group) Corporation (CNBM), established in 1984, is one of the largest State-owned group corporations of building & mechanical materials which specializes in the design, manufacturing and distribution of building materials in the world.
As the whole world turns “green”, CNBM enters into the Photovoltaic Industry in 2005.After 6 years' fast growth, now our annual capacity is 500MW solar panel and 500MW solar cell.

- Q: Do higher watt solar panels last longer, efficiency-wise? 3 installers gave me quotes with 3 different sunpower panels. The 225, 25, 20 watt panels. Whats the con and pro's of the different wattages?
- You should get the highest efficiency at the lowest price. Typically, the Sunpower brand panels have the industry best 23% efficiency depending on the model. You have to look at the specification very closely and if you don't see it, ask. There are two types of solar cells Polycrystalline and Monocrystalline. Polycrystalline cells are inferior to Monocrystalline. You will also see that different kinds of panels have different output voltages.Since you will be wiring your panels together and connecting them to either a power inverter or a charge controller (if you have battery backup), you need to make sure the panels and controller work together for maximum efficiency. Be very careful when engaging an installer especially when they are trying to sell you the equipment too. Mostly, these are not engineers and you will end up with whatever they have in stock without regard for the most optimal design.
- Q: Can solar panels be installed on a house with a flat roof?
- Yes, solar panels can be installed on a house with a flat roof.
- Q: Solar panels are costly.Do you know any inexpensive way?So that i can make one of my own.
- Solar things are always costly... You can use concave mirrors and concentrate the heat and heat what and then steam ll be formed and then steam directed to turbines, there you go generating electricity with out solar panels...
- Q: How do solar panels affect the property's green certification?
- Solar panels can have a positive impact on a property's green certification. By generating clean and renewable energy, solar panels contribute to reducing the property's carbon footprint. This aligns with the criteria for green certification, which typically includes factors such as energy efficiency and sustainability. Installing solar panels can enhance a property's overall sustainability profile, making it more likely to meet the requirements for green certification.
- Q: I am completely ignorant on this subject. I was just wondering out of curiosity of how many solar panels and equipment that it would take to run a central ac for a 2500 sq ft home and a pump for a medium sized pool. I'm talking running ac for like 8 hours a day to keep around 65-70 degrees and running the pump 24/7. Just looking for a general ballpark answer.
- Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
- Q: how much electricity will produce in Kwh by a 000 W solar panel in a sunny tropical area per day (good sunlight at least 0 hour a day)
- Solar okorder /
- Q: I would like to know how do you build a solar panel?
- At first, you will need about one square foot of thin copper plate, two alligator clips and short leads of wire, a wide mouth glass jar, tap water and salt. Cheers,
- Q: Do solar panels require regular cleaning?
- Yes, solar panels do require regular cleaning to maintain their efficiency. Dust, dirt, bird droppings, and other debris can accumulate on the surface of the panels, reducing their ability to generate electricity. Regular cleaning ensures optimal performance and maximizes energy output.
- Q: are solar panels just a photodiode?A Photodiode converts light into either current or voltage? Right?
- Yes, so are camera sensors. Except in cameras they're specially desgined to reduce noise.
- Q: Due to erratic power cuts in my area I want to make up by using a 30watt solar panel. My decoder is 30watt but my TV is 70W. I need something small. I don't have problem with sound. Just picture.
- Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
