Introduction of Poly solar panels CNBM
Polycrystalline Solar Panels 250W 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: I have a home in Manchester Tn and we have been slowly remodeling the home. It is about 200 sq ft of living space. Our normal electric bill is about 50 a month. We would like to add some solar panels to the home to help reduce the amount of the bill. How many panels do I need and what would be the cost? I am not trying to go completely of the grid but I would like to start somewhere and maybe over the years be able to add. What is your recommendation for a reasonable cost of under 2 to 3 k??
- Unless there has been some major breakthrough in solar panel efficiency - Forget it. I had looked at some utility interactive systems where the electricity generated by the solar panels went through a special inverter and into the electrical system of the house, any power you didn't use went backwards through the meter and into the grid. I figured that even if it was sunny every day, it would take about 20 years to break even on the system. That is, if I had invested $5,000 in a small system, to save $5,000 off the electric bill would take 20 years. If I had $5,000 to invest, this wouldnt be the place! It would take much more than 20 years of electrical savings to match even a modest investment. Then, don't forget what happens if 0 years from now the inverter or some of the panels fail and need replaced. Invest in fluorescent lights, maybe even LEDs. You will see a much quicker return on investment. Install more insulation, put in a heat-pump system. I appreciate you desire to save some energy, solar just isn't going to be worth doing, at least not yet.
- Q: I would like to know if I had a mobile kitchen could I power it from solar panels mounted atop the vehicle (truck).(to power electric kitchen equipment, i.e. stove, deep fryer.), instead of propane…could I possibly connect the solar panels to a battery to save my generated electricity? If solar panels would not be enough power could a small windmill suffice…?
- The best way to find out is to determine the wattage of each piece of equipment you want to use and how many hours you want to use those pieces of equipment. Finally, calculate the total number of Watt-Hours you need at minimum. Then you need to research solar panels or mobile wind mills (they need to be pretty huge to get a decent amount of energy I think, so solar power is probably the way to go). You will need to figure out the efficiency of the solar panels, the size of the array, how you will turn it or if you will turn it at all (to face the sun to get the maximum energy input, or maybe to use mirrors so you don't have to turn it. Once you find a good configuration for your mobile kitchen, you need to calculate if the Watt-Hours you will generate on an average day (with average weather) is enough to power the equipment whose energy requirements you previously calculated. Then you have to keep in mind that some days will have no sun, and you may not be working on some days, but you can still capture sunlight. For each case, a large battery array will be required. If you had a guage on that array, you could also hook it up to the a small generator in case you need immediate power. It's an eco-friendly process, but the initial cost is high and it requires a lot of research and planning. This is why most people do not do it--not because they don't want free energy from the sun, but because it's not easy to start collecting that energy in an efficient way. Sorry I couldn't give you more specific numbers, but a solar panel sales agency should be able to estimate whether or not you could do it (they'd probably set it all up for you too). ^_^
- Q: Can solar panels be used to power an entire office building?
- Yes, solar panels can be used to power an entire office building. By installing a sufficient number of solar panels on the roof or in a separate solar farm, it is possible to generate enough electricity to meet the energy demands of an office building. Additionally, advancements in solar panel technology and energy storage systems make it more feasible to rely solely on solar power for an office building's energy needs.
- Q: Can solar panels be installed on disaster relief shelters?
- Yes, solar panels can be installed on disaster relief shelters. Solar panels provide a sustainable source of energy and can help power essential equipment and devices in these shelters, such as lights, communication systems, and medical equipment. This reduces the dependency on traditional energy sources and ensures uninterrupted power supply in critical situations. Additionally, solar panels are lightweight and portable, making them suitable for temporary shelters and easy to transport to affected areas.
- Q: Can solar panels be used in areas with high levels of vandalism?
- Yes, solar panels can be used in areas with high levels of vandalism. However, it is important to implement additional security measures, such as installing anti-vandalism devices, using tamper-proof mounting systems, and employing surveillance systems to deter potential vandals. Regular maintenance and quick repairs are also crucial to ensure the optimal functioning of solar panels in such areas.
- Q: Can solar panels be installed on a data center or server room?
- Yes, solar panels can be installed on a data center or server room. By harnessing solar energy, data centers can reduce their reliance on traditional energy sources and decrease their carbon footprint. Installing solar panels not only helps in generating clean and renewable energy but can also lead to long-term cost savings by reducing electricity bills. However, the feasibility and effectiveness of solar panel installation may depend on various factors such as the availability of adequate roof space, local climate conditions, and the energy requirements of the data center.
- Q: i need someone to advice me which solar panels to buy.i have looked into few companies and i need some more info before decidingthe companies i checked were Sun tech trina solar Canadian solar and LDK solar.whice company should i pick?? please help.
- Are you talking about buying panels, or investing in stock? LDK does not make panels, they make solar grade silicon that goes into panels. I haven't heard bad buzz recently about any brand of panel. Therefore, I would go by price per watt alone. If you type in solar panel price into Google, you're sure to get directed to the major sellers, each of whom will sell many brands of panels. There are a couple other requirements that I would have for a serious system: ) Safety certification such as UL. This will be legally required for a grid-tied system. All panels except the really fly-by-night brands and factory seconds have this. 2) 25-year performance warranty. It's standard now for a manufacturer to guarantee that their panel will still produce 80% of the rated output after 25 years. Older panels may say 20 years. Junk panels will have no such warranty, or something ridiculous like 90 days or year. 3) Crystalline silicon. Monocrystalline or polycrystalline doesn't matter. Every few years, someone claims that they have an amorphous or thin-film technology that's durable. Being conservative, I'm still waiting for such things to be proven. Some crystalline panels have been in service since the 70's, although they are pitifully weak by today's standards. I've heard good things about the Sanyo HIT hybrid panels, but that's only from one person who had them installed.
- Q: Can solar panels be installed on warehouses or industrial facilities?
- Yes, solar panels can be installed on warehouses or industrial facilities. In fact, these large open spaces are often ideal for installing solar panels due to the ample roof space available. Installing solar panels on warehouses or industrial facilities can help generate clean and renewable energy, reduce electricity costs, and contribute to sustainability efforts.
- Q: I am in need of solar panels and the batteries that I can store the energy in. I need to be able to run a laptop, cell phone, and LED lights from it. When I research I see all sorts of options with regards to watts, VMPs, and AMPs. I also see that I may need a controller, an inverter, and various other components. Can anyone help me through these terms and what i need to know in order to efficiently generate and store the electricity. Thanks
- Unlike what most people seem to think, solar panels are not advanced enough to power day to day objects that we use, with the sun that we see in a day. You would need mass amounts of panels and equipment. IF there is a smaller solutions (which I doubt would do what you're asking yet) it would cost thousands of dollars. Panels are not there yet, and the ones that are, are still in development or being guarded from release to the public. The most you'll get out of a few hundred bucks and panels is a lit garden for a few hours at night. Go buy rechargeable batteries.
- Q: Can solar panels be installed on mobile homes?
- Yes, solar panels can be installed on mobile homes. In fact, mobile homes can be great candidates for solar panel installations due to their smaller size and affordability. Additionally, solar panels can help mobile homeowners save on electricity bills and reduce their carbon footprint.
