About us

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

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. 


This installation Manual contains essential information for the electrical and mechanical installation that your must know before installing CUSTOMER PV modules. This also contains safety information you need to be familiar with .All the information described in this manual are the intellectual property of CNBM and based on the technologies and experiences that have been acquired and accumulated in the long history of CUSTOMER. This document does not constitute a warranty, expressed or implied.

CUSTOMER does not assume responsibility and expressly disclaims liability for loss, damage, or expense arising out of in anyway connected with installation, operation, use or maintenance of the PV modules. No responsibility is assumed by CUSTOMER for any infringement of patents or other rights of third parties that may result from use of PV module.

CUSTOMER reserves the right to make changes to the product, specifications or installation manual without prior notice.

 260W Polycrystalline Silicon Solar Panels


The installation of PV modules requires a great degree of skill and should only be performed by a qualified licensed professional, including licensed contractors and licensed electricians. Please be aware that there is a serious risk of various types of injury occurring during the installation including the risk of electric shock. All CUSTOMER modules are equipped with a permanently attached junction terminal box that will accept variety of wiring applications or with a special cable assembly for ease of installation, and they do not require assembly.

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?

Q:How do solar panels work?
A solar panel is a collection of solar cells (photovoltaic cells) connected together and put in an enclosure. The solar cells work by taking advantage of the photovoltaic effect. The effect is that in a semiconductor P-N junction, when photons of suitable energy strike the junction, an electron and electron-hole pair are generated. This creates a voltage difference between the two sides. When this voltage is applied to a circuit, the electrons are able to flow through, creating usable energy.
Q:How does Solar Panels works and what is the cost of getting a solar panel installed.?
solar panels are a waste, I work for the biggest energy producer on the east coast and we are required by some really dumb laws to have many types of energy sources, fo course the only ones we make money on are coal and nuclear, solar panels we lose a ton of money on because they never make up for the cost it takes to buy them, and technology cannot bring them down because their too expensive even with a gov't subsidy bc of the products to make them. Don't waste your time with them, if you want to save money get a wood furnace
Q:Solar Panel - Battery Charger 2V?
How many amps will you need? Remember v x a = power. The way those trickle chargers work is by sacrificing some amperage to get up to 2 volts. If you can invent closer to ~3V range that solar cells naturally produce thing will likely work better. A sign or a light that doesn't need a lot of power will work. Automobile battery packs might take a month to charge. Solar-Powered 2V Trickle Chargers are used mostly to keep things like boat batteries in storage from discharging, not to charge them.
Q:How Can I Reduce A Solar Panels Output To 3volts From 9volts?
Solar panels generate DC power. Changing DC voltage is hard, which is why the power grid is AC voltage. AC voltage can easily be changed with a transformer. To keep the DC power (watts) the same at a lower voltage you need a DC to DC converter. That basically changes the power to AC with an inverter, changes the AC voltage to the new value, then rectifies it back to DC. It is probably hard to find a commercial unit that handles those voltages and then it will be expensive. But I have a simple solution in the special case of a solar panel. Solar panels are made up of smaller solar cells. The basic solar cell has a very low voltage, like half a volt. The panel has many of them connected in series to make a higher voltage. Just cover (shade) some of them and the voltage generated by the panel will be less. Of course that reduces the power. And you may need to experiment with shading different parts of the panel and measuring the result with volt meter.
Q:how does a solar panel works?
The fourth answer (kinetic energy) is totally wrong except for follow the instructions If you don't have the basic qualifications, you shouldn't even try besides falling off your roof and electrocuting someone else with bad connections. Solar panels produce low voltage DC power (up to 48 volts depending on design) which can be used directly but rarely is. DC power is stored in batteries for night, overcast days, and times of higher usage. The battery power must be fed through an inverter to produce 20 (or 240) volt AC power that your appliances use. The inverter to house connection must be made in a way that when the main power is turned off (like for repairs) your solar sourced power is not on the wires to hurt someone.
Q:How much is the average solar panel?
Completely self-efficient and autonomous??? Forget it. Too expensive. It's only worth if you use like 8 lights (2-20w) about 4 hours a day, a fridge, a tv about 4 hours/day and basically nothing else or a few low consume stuff. Forget about microwaves, dryers, or other stuff. Too much watts. And that would cost you no less than 5000-6000$. You need panels (about 4 or 6 20w would suit maybe), 2 batteries (about 600Ah at least), inverter(500w/24v) and a regulator, lets say a 30A one. Just stick to normal energy supply. A single 20w panel may cost about 750$ at least.
Q:Parts needed to build a solar panel?
You need to talk to your local power utility to see what they require for you to connect your solar power system into the grid.

Q:Charge Laptop with Solar Panel?
humm..... .need HUGE solar panel (alot) 2. wires 3. aligato clips . put the panels on the roof 2. use the aligator clip to clip the wire from the panel to the bars of the pluger of the comp. charger 3.tada mark me best:)
Q:where to face solar panels?
The following links is a sun angle calculator which I find very helpful during my days of doing project about solar panel. The calculator will give you the accurate location of the sun. Solar panel work best when it is directly facing the sun. All you have to do is key in your location details and it will provide you with two most important details: azimuth angle and altitude angle. Azimuth angle is the East angle where the Sun is relative to the South while altitude angle is the tilt angle of the solar panel throughout the day. By using these two angles, you will maximize your exposure of solar panels. However, if you are experiencing rainy or cloudy days, horizontally mounted solar panels is the most efficient.
