Company Profile

China National Building Material (CNBM) Group Corporation

255W ,Poly Solar Panels with CE,TUV,UL,ETL,MCS Certificates

 

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: Can solar panels be used in combination with other renewable energy sources?
Yes, solar panels can be effectively used in combination with other renewable energy sources such as wind turbines, hydroelectric power, or geothermal energy. This combination, known as hybrid renewable energy systems, allows for increased reliability, better utilization of resources, and a more stable power supply.
Q: Can solar panels be installed on restaurants or food establishments?
Yes, solar panels can be installed on restaurants or food establishments. In fact, many restaurants and food establishments have embraced solar energy as a sustainable and cost-effective solution. Solar panels can be installed on rooftops, parking lots, or even as shade structures over outdoor seating areas. By harnessing solar energy, these businesses can reduce their reliance on traditional energy sources, lower their electricity bills, and contribute to a greener environment.
Q: Ok Im trying to power my room using solar panels and I've figure out that I need about 700 watts to do so, but I really only use my electronics at night. I was wondering if I could buy lets say a 200 watt solar panel and let it charge a battery all day would that work? I live in southern california so I dont have to worry to much about cloudy days. also any suggestions on where to buy a panel, inverter, charge regulator, and battery?
What you really need to calculate is your energy requirements, you are only stating your power requirements. Power (W) = how many watts of power are you using? Time (h) = how long are you going to use the power for? Energy requirement(Wh) = W * h take the answer to that equation and plug it into the exact same equation except substitute how much sunlight you get for h and then solve for W to find what you need in the way of a solar panel. Wattage of solar panel (W) = Energy requirement (Wh)/hour of sunlight per day (h) Now you know what wattage of solar panel you need. For the battery you use a different equation: Energy in the Battery(Wh) = Battery Voltage (V) * Current Capacity (Ah) Solving for Current Capacity: Ah = Wh / V This will tell you how big a battery you need, but you also need to be concerned about how much current it can source. For this you need to know what your peak power requirement is. Wmax = peak power requirement Max discharge current (Amax) = Wmax / Vmax Also you will need an inverter rated to Wmax as well.
Q: Can solar panels be installed on a military vehicle or equipment?
Yes, solar panels can be installed on military vehicles or equipment. In fact, many modern military vehicles are being equipped with solar panels to harness renewable energy for various purposes, such as powering communication systems, electronics, and auxiliary equipment. This helps reduce reliance on traditional fuel sources and increases the operational efficiency and sustainability of military operations.
Q: Can solar panels be installed on golf courses?
Yes, solar panels can be installed on golf courses. In fact, many golf courses have already embraced solar energy by installing panels on their clubhouses, maintenance buildings, or even on the course itself. The large open spaces and ample sunlight available on golf courses make them suitable for solar panel installations, providing an environmentally friendly source of renewable energy.
Q: Can solar panels be installed on flat surfaces?
Yes, solar panels can be installed on flat surfaces. However, for optimal performance, it is recommended to tilt the panels at an angle that allows them to capture maximum sunlight.
Q: Can solar panels be installed on a theme park or amusement park?
Yes, solar panels can be installed on a theme park or amusement park. In fact, many theme parks around the world have already installed solar panels to generate clean and renewable energy. This not only helps to reduce their carbon footprint and dependence on fossil fuels but also saves them money on electricity bills in the long run. Additionally, solar panels can be integrated into the design of the park, complementing its aesthetic appeal and showcasing the park's commitment to sustainability.
Q: Solar panel for battary charging
What you are stating is that the battery you have will operate the UPS for about 2 hours before it is drained past the point of no return (technically 2.82 hours, but that would be a dead battery - most well-designed UPS systems cut off when the battery gets below about a 30% charge so that battery is not damaged. Lead-Acid batteries have about a 0%/month self-discharge rate if there is no load connected. The very best systems are as low as 3%, the worst are over 20% - and all at a 'normal' temperature. So, you will need a maintenance charger of about ten (0) watts or so - amp will be more than enough. And about any solar panel will handle that much with the proper charging connection.
Q: What, if any, improvement in efficiency per square foot or meter is realized by a solar panel in space vs. being mounted on the ground where the light is attenuated by the atmosphere?In passing, I found a site that gives an output of .89 watts / 4 in. sq for a particular home-mounted panel.
I'm not sure on the exact numbers of solar panel efficiency, however i do know that at the radius of the Earth we should be receiving about 000W of power per square meter. This value is lessened by the atmosphere to a value closer to 600W per square meter on the Earth's surface. (on a really hot day) That's a 40% drop in power due to the atmosphere. I'm assuming that the solar panels being in space don't affect it's efficiency (as in mechanically). So its power generation should increase by about 40% when in space compared with a ground based panel of the same design. Hope this helps, Sorry it's kinda sketchy info...
Q: How can solar panels be used for heating water?
Solar panels can be used for heating water by using the energy from the sun to heat up a fluid, typically water or antifreeze, which then transfers the heat to a storage tank. This heated water can be used for various purposes such as showers, washing dishes, or heating indoor spaces.
