Solar Polycrystalline Series Panels
Introduction of Solar Polycrystalline Series 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:Green issues aside, are solar panels worth it, monetarily speaking?I don't mean that my house might be worth more or any of that. All I am asking is this: if I invest in a set of solar panels, will the cost be paid back to me over time? If so, how long will it takegt;Take into account the following:. Currently I pay the electric company around $00 per month2. I use around 400 kilowats of energy per monthI realize that exact numbers are hard to come by, but any opinions are welcome.
- There are several factors to consider when looking into solar power for your house. If you want to replace your use of utility electricity with solar power for say a 500 - 2000 square foot home then the system will cost you at least $30000 - $50000 to install. You will also have the maintenance issue of your storage batteries, panels, and inverter which will eventually wear out over time. So lets say we have an optimistic price of $30000 for a whole house system (this would be really cheap), dividing this by your yearly consumption would give you the amount of years it would take for the expenditure to pay for itself (not counting maintenance which could be costly). The payoff would be about 25 years, so all things remaining equal, I would say that it is a bad investment. Solar panels as they are manufactured today do not have a very long life span. They will greatly decrease in efficiency after several years and will most likely need to be replaced in 0 years. The panels themselves are the greatest expense. You could problably find better ways to make/save more money by investing $30000 - $50000 somewhere else IMHO. Solar technology is still not at the point where it is profitable in the sense you are thinking about. Unless of course, there are huge tax incentives for you or large rebate programs through your local utility, but you would have to do the math on that as well. If you are thinking small as in a couple panels to supplement your utility electric, the above still applies as well. In fact will it take longer to recoup the cost of a smaller setup. Hope this helps!
- Q:I have 2 20 watt Solar panel. I have it hooked up to solar controller and batteries to inverter. Am trying to figure out how much watts am getting. I found the voltage but how do I find the amp reading on a mutimeter?
- While you can measure voltage on a like without a load, the measure of amperage is more closely related to the amount of power that is being drawn. The amperage is measured with the meter in series (not parallel like voltage) with the load. What it ends up measuring is the load that is being drawn from the solar panel and not the potential of the panel.
- Q:How do solar panels impact the local job market?
- Solar panels have a positive impact on the local job market as they create new employment opportunities in the renewable energy sector. The installation, maintenance, and manufacturing of solar panels require skilled workers, which leads to job growth and economic development in the community. Additionally, the transition to solar energy promotes a shift towards clean energy sources, attracting more investments and creating a sustainable job market for the future.
- Q:How do solar panels affect the roof warranty?
- Solar panels generally do not void a roof warranty, but they may have some impact on it. The installation process of solar panels involves drilling holes in the roof, which can potentially cause leaks if not done properly. Therefore, it is important to hire a reputable installer who is experienced in working with solar panels and understands the intricacies of a roof. Some roofing manufacturers may require specific mounting systems to be used, and failure to comply with these requirements may void the warranty. It is advisable to consult with both the solar installer and the roofing manufacturer to understand any potential impact on the roof warranty before installing solar panels.
- Q:My family has been interested in solar technology for a long time. I want to know how to save money so I can get as many solar panels as possible. I know the government has different discounts/ grants, and there may be tax incentives. I am not looking to sell energy to the energy company I want to use the energy directly.
- Nothing good comes from the government ,nothing .so why would you think they would really help in this matter . If the government is involved , that is a good indicator to stay away.
- Q:I bought a pack of OEM mini solar panels that produce 4.2v and 22mA and I was just wondering how many LED's I could hook up to one mini solar panel? I currently have one green LED with a resistor on the one panel but was wondering how many I could possibly run off of one panel?
- You need to answer that by designing circuits to provide each LED with its specific voltage and current requirements, and then see how many you can supply.
- Q:Can solar panels be used for charging electric vehicles?
- Yes, solar panels can be used to charge electric vehicles.
- Q:ok so when a solar panel is marked as a certain wattage dose that mean it makes that much in a day in an hour or constant, dose it still work at night or what ? is it worth it or is it more of a pain? can some one tell me what all the watts and volts mean ?? and can some one tell me what a kilowhat is in refrence to some thing i understand like howmany loads of laundey can you do wt a watt? i need help understanding this stuff?
- You okorder /
- Q:Hey guys :)Well I'm in the middle of doing my PSHCE coursework on sustainable energy, focusing on solar panels. I just wanted to ask you what your opinions are of them? Are they really worth it? Are they sustainable? Will they reduce our energy bills? Those sort of questions :)If you are interested in installing solar panels, please mention that, as it would be great! There's lots of information about them on this site ----
- Bing solar power in Germany. Solar power has an option of assisting in removing some of the burden during daylight, from power generation plants. Anything is a help. Plus they will continue to do it forever (at least a lifetime). But they are not the total answer. Like wind, limited to certain areas. Wave generation is another solution, but still limited to coastal areas. The current design of most supply grids does not allow transportation of power long distances. You want a real eye opener, Bing transportation line looses power grid and see how much energy is wasted, and the amount of carbon put into the air for these losses.
- Q:im making an energy efficiant house for science class and i need to price the house. im putting solar pannels on the roof and would u please tell me how much they are per like 2 sq. feet of a pannel?
- You are way out of your depth if your report for science class is supposed to be knowledgable. First of all, Solar panels alone will NOT be enough to charge the battery bank, which you don't even mention in your quesiton. Secondly, the only way to have a usable 2 VDC system is to use a wind generator to keep the batteries charged to capacity and, as a plus, they will work at night. A 65 Watt ARCO Solar Panel is about $300 and you need to figure your power by the Wattage Rading for the particular panels . You also need to add in the cost of a 2VDC to 0VAC invertor, monitoring panels etc.... AND... just how big is the ROOF of the house you are planning to use.? This is an area of involved study and it's a bit more than what you are imagining for your high school science class report.
