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.

Q:What is the difference between monocrystalline & polycrystalline solar panels?
The polycrystalline solar panel has a longer life-span and has a higher efficiency. What this means is that from the energy that 'hits' the solar panel, more is caught and used to convert into electrical energy. A polycrystalline solar panel will have an efficiency of about 4%. The monocrystalline solar panel has a similar efficiency but the cells are prone to sunlight, so the efficiency drops over the years.
Q:How do you hook up solar panels to your electricity?
nowing what to do with unused renewable electricity is always a dilemma – hooking up to the grid has to be the preferred option. If your residential home is grid tied, i.e. connected the electricity grid as opposed to off-grid and you are using solar panels to generate electricity. Then it makes a lot of sense to hook your solar panels to the grid, because instead of losing the unused electricity or having to maintain a bank of deep cycle batteries, you simply feed it back to the grid. You feed electricity back to the grid via your electric meter which measures the electricity in Kilowatt per hour. This has the effect of reversing your meter which in turn reduces your electricity bills and if you are generating a lot of electricity you could find the utility company owing you money! The Solar Powered System Therefore, your solar powered installation would look like this. The solar panel will connect to an “array disconnect” – you need an array disconnect for system maintenance because it allows you to easily shut off the power. The array disconnect is connected to an “inverter”. The solar panel generates DC power and the electricity from the grid is AC power. Therefore, you need an inverter to convert DC power to AC power. The inverter is connected to an “AC breaker panel”. This is the interface where your solar generated electricity meets the electric meter and allows you to feed electricity back to the grid. Now in most countries and states you are not allowed to tamper with the electric meter so at this point you should contact your local electricity energy supplier and ask them to supply an engineer to hook you up to the grid. If you have anything to add to this article or you have connected your system to the grid – tell us how you did it by writing a comment below.

Q:solar panels for my home.?
Running an entire home on solar panels is not possible, I think. I have 24 panels (almost the whole south facing surface of my roof) and it's almost sufficient for electricity, but not for hot water and heating, that would require more than my roof could accommodate.
Q:Solar Panel HELP?
Sorry this is so long. I live in north west arkansas. I have solar on my home. I installed them myself. Did not cost me anywhere near 25 grand. Solar will pay you back if you get incentives or not. I have said this a hundred times but people just don't seem to understand or can't do the math. You are renting from the public utility. You have nothing in the end but a stack of payment stubs. There is no way to get a return on your investment. You paid them money and have nothing. Nothing at all .. Well maybe good service. But still nothing. If you check it out most solar electric systems last 30 years or longer. If your electric bill is 00 dollars a month. do the math. 00 dollars a month for 30 years is $36,000 dollars you would normally pay the public utility. So why not buy your $25,000 system, you just made $0,000 right there on the spot. Now add in 3.5% cost of living per year for each year for the next 30 years on that 35,000 you pay the public utility. Then you have to keep in mind you do not pay taxes on any electric you make yourself. You do not pay fees on your own power. You do not pay the cost of fuel incresses every time the price of oil goes up. In the end you saved $00,000. So it is free even if Arkansas don't give free handouts like other states. I even know people who say they are waiting for some one to make a cheaper solar module. That will not happen because even if they make it for half the cost (like evergreen is doing) it will still be sold at standard market value not production cost. The real problem with solar is it is hard to come up with the upfront cost. But renting solar panels is comming but that is the same as just renting power from the public utility. I wish you luck but it will be a while before Arkansas will make any moves on renewables. They just in 2007 made it law that the public utilities have to let your roll your net metering over to the next month if you over produced.
Q:Solar panel power question?
NO ! Pump needs 747 watts power. And you need to buy one more expensive DC to AC converter to make it work. Use solar panel at least has 000W output.
Q:45 Watt Solar Panel Kit Harbor Freight?
Yes, 80 watts will be nearly twice as useful as 45 watts - but 80 is still a small number. Solar panel systems need an inverter and there's a slight energy loss at the inverter. And, if you want to use the day's energy at night, you'll need a battery or two. And every time you move energy into or out of a battery, you lose a little of the energy. All this is to say that you need to sum up the wattage of your appliances and add a fudge factor to accommodate for the losses. I looked at the kit and was moderately impressed. $200/45=$4.44/watt; that's a reasonable price but the links I left below talk of prices as low as $2.58/watt. Also the Harbor Freight kit doesn't contain an 'inverter' which you would have to buy. Also the wattage advertised for any solar panel assumes the thing is clean and pointed right at the sun on a clear day.
Q:Solar panel question..?
Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
Q:How much candle lights is required to operate a 205 watt solar panel?
The intensity of direct sun is about 0,000 foot-candles. It would not be practical to light that many standard candles and put them foot away from the panel, but you could supply that intensity with electric lighting. That's in fact how they establish the power ratings of a given panel; they have a rig that provides a standard test condition of sun.
Q:Do solar panels make electricity from light intensity or watts?
Light is power in the form of electromagnetic radiation from the sun. We receive about 000 watts per square meter on a sunny day. The solar panels do convert that sunlight into electrical power at a little less than 25% efficiency. Light intensity and power per square meter (W/m^2) are closely related. The more intensity, the more watts per square meter. So the answer is : Yes, from light intensity which directly proportional to watts per square meter
