About us

We are a high-tech group wich specializes in solar products design,research, manufacture, sales,solar projects design and installation. 

Our national sales service covers seven parts, including northeast, north, east, middle, south, northwest and southwest, international sales covers five continents and over forty countries, including Germany, Italy, Spain, France, America and Brazil etc. 

Our present annual capacity is 6 million for wafer, 60MWp for solar cells,200MWp for solar modules and one hundred thousand for solar applications. It is expected that the annual capacity of 2012 will be up to 30 million for wafer, 300MWp for solar cells, 1000MW for solar modules and 2 million for solar applications. 

 

COMPONENTS

 240w Polycrystalline Silicon Solar Panels

 

SITE SELECTION

In most applications, the PV modules should be installed in location where there is no shading throughout the year. In the Northern Hemisphere, The PV modules should typically face south, and in the Southern Hemisphere, the PV modules should typically face north. Please make sure that there are no obstruction in the surroundings of the site of installation. Take proper steps in order to maintain reliability and safety, in case the PV modules are used in areas such as: Heavy snow areas/Extremely code areas/ Strong wind areas/Installation over, or near, water/ Areas where installations are prone to salt water damage (*)/Small islands or desert areas.(*)

If you are planning to use the PV modules where the salt water damage may be possible consult with CNBM local agent first to determine an appropriate installation method, or to determine whether the installation is possible?

WIRING

To ensure proper system operation to maintain your warranty, observe the correct cable connection polarity(Figures 1&2) when connecting the modules to a battery or to other modules. If not connected correctly, the bypass diode could be destroyed.

PV modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative of the next module. Figure shows modules connected in series .

Q:how much watts can a x2 inch solar panel make?
Did okorder.com/ . Possibly this could immediately instruct each and every one!
Q:solar panel, dc light help?
3 w for 2 hours/night is 36 watt hours. You'll get about 500 watt hours/day from your panel on the average, which for a 2 volt battery is about 40 ampere hours. You can get an 80 amp-hour sealed gel cell battery to charge with this panel (with a suitable charge controller). You want to size your lights so the battery can provide three days of light without discharging it more than 50%, so that's abnout 600 watt-hours/3/36 = about 4 orf 5 lights. Cost for this system woulkd be over $500. The advantage of the self contained light is they use a lithium or nickel battery rather than a lead acid, so it can run totally dead without damage (unmlike a sealed lead-acid battery). That would be a far cheaper way to go. DK
Q:Reasons for installing solar panels in a school?
Solar panels give off no pollution, the only pollution produced as a result of solar panels is the manufacturing of these devices in factories, transportation of the goods, and installation. The production of energy from the use of fossil and some renewable fuels (e.g. wind turbines) can be noisy, yet solar energy produces electricity very quietly. One of the great pros of solar energy is the ability to harness electricity in remote locations that are not linked to a national grid. A prime example of this is in space, where satellites are powered by high efficiency solar cells. The installation of solar panels in remote locations is usually much more cost effective than laying the required high voltage wires. Solar energy can be very efficient in a large area of the globe, and new technologies allow for a more efficient energy production on overcast/dull days. Solar panels can be installed on top of many rooftops, which eliminates the problem of finding the required space for solar panel placement. Another great pro of solar energy is the cost. Although the initial investment of solar cells may be high, once installed, they provide a free source of electricity, which will pay off over the coming years. The use of solar energy to produce electricity allows the user to become less dependent on the worlds fossil fuel supplies.
Q:Numbers behind Solar Panels?
For comparison, 36 of these make a normal 2V x 50W panel. Note they are not tabbed. This means you have to find a way to connect them yourself. The tabs are probably spot welded on by the suppliers. A supplier below has kits of these with tabs, as needed to connect them together. These are not suitable for grid connect, because the higher voltage needed makes do it yourself panels a dangerous and litigious thing to have on your roof. Maybe you could buy a smaller pack from the link below to compare tabbed and untabbed and work out what to do. Your power calculation is a bit incorrect because the sun is only present some of the time. The 36 cell module would produce 50W when square on to the full sun. The sun may be out for around 2h a day in some places and times of the year. However it is the equivalent of 5h full sun, because of the changing angle throughout the day. Look this up on the internet for your region. Temperate zones may be a lot less. One pack in your link is 36x3 = 08 cells. Thus 50W per pack x 5h a day gives 750Wh per day and 274KWh/y. In reality it will always be less because of regions, weather, clouds, dust, inefficiencies, aging of cells.
Q:can you hand make a solar panel?

Q:Is it worth installing solar panels on a house that has no South-facing roof?
The trouble is that it is so expensive to have installed and as you say it will take many years before you actually start saving above what the installation cost was, I personally would not go ahead and make that sort of investment, it would be more profitable to keep the money in a building society, get the interest from it and use that to pay for your electricity but the main thing that I have against solar Panels is that unless you stay in that house for at least twenty five years you will not reach the point where you are saving and to capitalise on it you would have to stay there for many years more, so you will not have the option of moving house without losing your investment and at the moment having solar panels does not increase the value of the property, it is just a good selling point, when you buy your new house, you would probably have to start all over again and then because of the years will never live long enough to reap any benefit from it.
Q:What specification of solar panel do I need?
Ive been employing the comparable photograph voltaic panels for 5 years, have flow some instances so as that they final lots longer than the roofs weve had over us. i'm coaching my young ones a thank you to construct wind turbines, because of the fact we shop having potential failiures whilst the wind blows. and recently its have been given very windy. I can charge banks of battery's and shop my place of work working from dc-ac converters.
Q:question about GE solar panels?
I know someone that paid $600 a panel. I am not sure what kind or size, sorry.
Q:How powerful are solar panels?
very hot it can attract the sun
Q:Homemade Solar Panel : Hi! guys i want to know what do you think about Homemade Solar Panel?
If you want to make hot water then they are easy to make. Search the web.
