Introduction of Poly solar panels CNBM
Polycrystalline Solar Panels 45W With High Efficiency
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.
Feature
1.Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.
2.Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.
3.EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.
4.Long lifetime: ≥25 years; Less power decrease.
5.Resisting moisture and etching effectively, not effected by geology.
6.The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

- Q: the solar panel works with LEDs, small bulbs,etc but neve with any dcmotor. Please help. I have a science exhibition.
- BECAUSE IT COULD ENOUGH SUPPORT ENOUGH CURRENT, VOLTAGE DROPS DOWN NEAR V WHILE OVERLOADED WITH MOTOR. BUY A VERY LARGE SIZE SOLAR CELL WILL FIX IT.
- Q: what is needed beside the panels and do you need an electrician to hook it up
- most times yes.
- Q: I am looking to get some solar panels for my home to just power a few lights, a fan or two. I have a generator but I want that only to power the fridge and maybe some other small stuff for convenience.But mainly want the solar panels for the lights and fans. Any one have an idea of how about I go to figuring this all out? Should I call a contractor or anything?
- depends on what light bulbs you have in watts.depends on how many you want on. for the power equation you take P which equals watts x I which equals amps and E which equals volts and you multiply the amps and the volts together to get the watts which the solar panel is generating. for example if you had 7 60 watt light bulbs you would need 420 watts generated. which if you got 50 watt panels each you would need 9 panels. and for what your talking about if you want the stuff to work when the power goes out you are going to need an inverter. not to be confused with a grid ti inverter. and a few batteries i recommend deep cycle batteries that are meant for solar panels. depends on what fan you have.
- Q: Can solar panels be installed on swimming pools?
- Yes, solar panels can be installed on swimming pools. These panels can help heat the pool water using solar energy, reducing the need for traditional heating methods and lowering energy costs.
- Q: Can solar panels be installed on a shipping container?
- Yes, solar panels can be installed on a shipping container. In fact, it has become a popular choice for off-grid and remote locations where traditional grid connections are not feasible. The flat roof surface of a shipping container provides an ideal platform for installing solar panels, allowing for sustainable energy generation in various applications.
- Q: Can solar panels generate electricity at night?
- No, solar panels cannot generate electricity at night as they rely on sunlight to convert into electricity.
- Q: What do these mean? I'm interested in doing a solar panel project. The problem is I know nothing about electricity, wiring, or panels so I've bought a small panel to experiment with first.I don't know what amps, watts, or volts are; what I should be reading on the batteries I will be charging? Or on the small appliances I will be running?The panel I bought has four settings:. 3V ---- 200mA2. 6V ---- 00 mA3. 9V ---- 50mA4. 2V ---- 50 mA(What is mA?)Also, will you give examples of what I can run with this? Make up any scenarios with whatever amps/volts/watts.
- . 3V 200mA. mA (milliAmp) = 0.00A; Power = 3V x 0.2A = 0.6 Watts. 2. 6V 00mA is 6 x 0. = 0.6 Watts. 3. 9V 50mA is 9 x 0.05 = 0.45 Watts. 4. 2V 50mA is 2 x 0.05 = 0.6 Watts. With the 3 Volts one you could connect it to a flashlight light bulb, that's is about the max you can get out of it. With the light bulb, polarity doesn't matter, but if you power a small transistor radio with it, then make sure the + goes to the + and the - to the -. Reversing it wouldn't work and in some cases you could damage equipment.
- Q: How are solar panels installed?
- Solar panels are typically installed on rooftops or open ground areas. First, the area is assessed for its solar potential. Then, mounting structures are installed securely on the roof or ground. Next, solar panels are attached to these structures and wired together in a series or parallel configuration. Finally, the panels are connected to an inverter that converts the DC electricity generated by the panels into AC electricity for use in homes or businesses.
- Q: So, assuming that a solar panel is flush with the ground (i.e. only the photovoltaic side is visible, the other sides are covered by dirt,) what would happen if it was run over by a car? How about an SUV? Would it break?Would the solar panel still generate electricity?
- Solar panels have tempered glass, and are tougher than they seem. On commercial buildings where the panels are flat, they have a person with a mop regularly clean them, and that person walks right on the panels. A car might crack the glass, but that could be solved by simply using stronger glass. The problem of putting a panel right in the roadway would mainly be that the cars passing over it shadow the panel constantly. On a rooftop installation, installers try to avoid even a tiny shadow from a vent pipe or overhead wire, as this has a larger effect than might be supposed. Also, road grime would quickly accumulate on the panel and reduce its efficiency. Glass would be slippery as a road surface, but that problem could be solved. Metal is slippery, too, but they make bridges out of it. EDIT: To clarify, I meant serious solar panels in the first paragraph. The hobby type that they sell at Radio Shack or Harbor Freight are fragile.
- Q: My plans are building several solar panels and have a battery bank. I want to be able to power the refriderator and freezer and occationaly an electric grill. How would This work exactly and what would the best way to hook this up to make it work? I want to be able to convert DC to AC. How many batterys would I need to make this work. I know when Civil unrest happens I want to be prepared. How would Wind Power work If I can get the equipment I need?
- Solar panels and wind/water turbines all produce the energy and feed it into the batteries. Outfeed from the batteries thru an inverter to an electrical panel. From panel to outlets, into which you plug standard appliances and items. You can also get some appliances that run off of 2volt. Check with r.v. companies and suppliers for these. You can also run low voltage wires straight from batteries to switches to lights, fans, etc if you put in 2v ones. Just like your car has lights, fans (ac blower), and radio. As for how many batteries you need will depend upon how much ebergy you will use. You will need to figure how much all of your items use per hour. Then figure how long your charging device could be down for at a time. Solar panels will not charge at all for the 8-2 hours of nightfall depending on your area. Wind turbines will charge day and night so long as wind is of sufficient speed. Water turbines will charge 24/7 so long as water source(creek, stream, river) doesn't run dry. Neccessity/hr=N, time without charging =T. N times T = the amount of backup power you need to get you thru till charging sysytem kicks back in.
