Product Description
Solar Monocrystalline Series Panels
Introduction of Monocrystalline Solar Panels
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.

- Q: Can solar panels be installed on a concert venue or entertainment facility?
- Yes, solar panels can be installed on a concert venue or entertainment facility. In fact, many large entertainment venues have already embraced solar energy to reduce their carbon footprint and lower energy costs. Installing solar panels on the roof or surrounding areas of these facilities can generate clean and renewable electricity, which can be used to power the venue's operations or be fed back into the grid. Additionally, solar panels can serve as a visible commitment to sustainability, inspiring others to adopt renewable energy solutions.
- Q: I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.
- Yes, you can purchase a solar photovoltaic array to keep your batteries charged. You will need a Photovoltaic Cell Panel that produces 27 + watts (6volts x 4.5 amps = 27 watts) at 6 volts of electricity, a Charge Controller that allows only 4.5 amps of power through to the battery and will reduce the amps as the battery nears full charge and shut off the Panel when the battery is fully charged, and a 6v. Battery. Figure you will need a photovoltaic panel capable of producing a minimum of 27 watts if you are going to charge a completely dead 6 v. battery in one day. (with a clear sky). The way the system works is the sunlight strikes the cells on the panel and releases the excess electrons in the cells, they travel along central wires to your battery and charge the battery. When the sun sets, the procedure is reversed and the electrons flow backwards from the battery, into the photovoltaic cells. That is where the Charge Controller is needed. It acts a one way gate and lets the electrons go into the battery, but won't let them go backwards to the Panel. Just set your panel in the sun at the optimum angle for the season and your latitude on earth, connect the charge controller and then the battery, and it will keep your battery charged. Don't waste your money on the small wattage solar photovoltaic systems that claim to keep your battery charged. They simply can't do it unless your battery is in like new condition and is fully charged when they are hooked up. If you battery is a few months old, the small wattage photovoltaic systems can't keep up with the loss of power from sulfation inside the battery.
- Q: Can cold light make solar panels power
- permanent, clean and flexible three major advantages of solar cells long life, as long as the sun exists, solar cells can be an investment and long-term use; compared with thermal power, Solar cells do not cause environmental pollution
- Q: For my exam in science we are required to make a power point explaining why it would be good for our school to switch to solar. our complete handout given to us by our teacher is as follows:Power Point to include:. What you propose for alternative energy usea. Any thoughts on energy conservation...2. Why this is a good idea3. What information you would give the solar company (area of roof space your group determined to be useable for solar)In PowerPoint - include your quot;scriptof what you would be saying when the slide is up in the Notes section below the slideANY HELP WOULD BE GREATLY APPRICIATED!!THANK YOU SO SO MUCH,QH
- Refuse to do the work on the grounds that it is not good for your school to switch. If the teacher tries to give you an F, escalate the problem to the principle and then the local news agency. Teachers are not allowed to force brainwashing.
- 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: How do solar panels impact the electric bill?
- Solar panels can significantly reduce or even eliminate electric bills by generating electricity from the sun. By harnessing solar energy, homeowners can offset their electricity consumption with clean and renewable energy, therefore reducing their reliance on the grid and the associated costs. Additionally, excess energy produced by solar panels can be stored in batteries or fed back into the grid, allowing homeowners to earn credits or compensation for the surplus electricity they generate.
- Q: What is the impact of roof material on solar panels' performance?
- The choice of roof material can have a significant impact on the performance of solar panels. Certain materials, such as metal or asphalt shingles, are more conducive to efficient solar panel installation and operation. These materials provide a stable and sturdy base for mounting the panels, ensuring proper alignment and minimizing the risk of damage. Additionally, the reflectivity and heat absorption properties of the roof material can affect the overall efficiency of solar panels. Light-colored or reflective roofs can help reduce heat absorption, keeping the panels cooler and improving their performance. On the other hand, darker or less reflective roofs may lead to increased heat buildup, potentially reducing the efficiency of the panels. Ultimately, selecting a suitable roof material is crucial in maximizing the effectiveness of solar panels and optimizing their energy generation capabilities.
- Q: Can solar panels be installed on a community center or social gathering place?
- Yes, solar panels can certainly be installed on a community center or social gathering place. In fact, these locations are ideal for solar panel installations as they often have large roofs or open spaces that receive ample sunlight. Installing solar panels on such facilities not only helps to reduce electricity costs but also promotes sustainability and environmental awareness within the community.
- Q: I don't see much solar panels on people's houses where I live. I got a long time to go before doing so but I was planning on buying a few solar panels when I retire in the far future. In your opinion, is such an investment worth it? Would you buy them? I realize they are very expensive hence why I said when I retire. Thanks for your opinion
- Solar power is still an expensive way to purchase power, as of 2007, it was 38 cents per kwh while the cost of power from coal is 0.6 cents per kwh. Of course regulations have prevented new coal power stations from being built so it's really natural gas power stations at 5 cents a kwh that solar has to compete with. Solar is dropping in price but the best you can hope for is for it to reach parity with natural gas someday soon and it hasn't yet. The other issue is that you pay up front for solar power which as any economist will tell you is even more expensive and involves greater risks. However, as part of a strategy to become as self reliant as possible when you retire and have a fixed income, it's a reasonable prospect, not only will the technology become less expensive by then but at that point, fixing the price of the energy costs is more valuable than the cost of the energy. Focusing on personal finance and learning how to invest which very few people know how to do is more important right now. When you retire, hopefully you can afford to build a passive solar home with photovoltaic solar panels and wind turbines but still on the grid for efficient net metering and with a greenhouse where you can grow the staples that you need and perhaps even some biodiesel for your google driven car. Having a reasonable portfolio is really the only way to achieve that goal.
- Q: I'm looking into buying solar panels, there are all kinds of ranges of energy output...but my question is, when ti says...say 50 watts of power...does that mean 50 watts a day, an hour, a minute, what?
- A 50-watt rating means the panel will produce 50 watts as long as the standard conditions are maintained. So if you had this bright sun and cool temperatures for 6 hours, the panel would deliver 50 x 6 = 900 watt hours, or a little shy of kilowatt-hour. Kilowatt-hours (kWh) is the reading on your electric bill. However, like most advertising, the 50-watt number is not realistic. They assume that the air surrounding the panel is very cold. 25 watts is a better number to use for this size of panel for engineering purposes.
