Introduction of  Poly solar panels CNBM

Polycrystalline  Solar Panels 245W 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.

 Polycrystalline  Solar Panels 245W With High Efficiency

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:For example, If I were powering my house with solar panels, would it be more efficient or effective, (or I guess would I get more energy) out of a day that measured 90 degrees Fahrenheit as opposed to a day that is 70 degrees Fahrenheit.
Nope. Sunlight is.
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.
I'm confident that you must pick up everything concerning solar power at www.okorder .
Q:I thinking of buying a few solar panels, can anyone who had bought solar panels or sells them give me a price for them. I dot wanna over spend on them...
Solar okorder or another site to compare prices.
Q:How do solar panels affect the property's carbon footprint?
Solar panels can significantly reduce a property's carbon footprint by generating clean and renewable energy from the sun. Since solar panels produce electricity without emitting harmful greenhouse gases, they help to offset the carbon emissions associated with traditional energy sources. By using solar energy, properties can reduce their reliance on fossil fuels and make a positive impact on the environment by reducing their carbon footprint.
Q:I had installed over the summer a solar panel system on my house. Hers some infofor you: I live in MOThe system cost 25K (Rounded numbers)The Rebate from the utility company was about 0KThe expected tax rebate will be about 5KI have a home office from which I work and is 5% of my homes sq footage. My question is though I am getting a basic tax rebate, should I be able to claim part of this off as an expense for my home office?It seams logical since I used to deduct part of my electric bill and I there for should be able to write off part of this. I am, after all using electricity and getting a bill from the utility that is higher than it would be if I didn't have the office2. If so which amount should it be? The full 25K or something after the rebates.
You would have to depreciate the office portion over a very long time frame in years. Contact a qualified tax professional as home office deductions set off all sorts of red flags.
Q:Can solar panels be used for powering electric boats or marine vessels?
Yes, solar panels can be used to power electric boats or marine vessels. Solar panels convert sunlight into electricity, which can then be used to charge the batteries of electric boats or directly power their electric motors. This sustainable and renewable energy source offers a clean and environmentally friendly alternative to traditional fossil fuel-powered propulsion systems for marine transportation.
Q:Any recommendations for companies? Any things to look out for?
It strongly depends on where you live. In California or Hawaii, for example, solar can be cheaper than the power company, even without subsidies. Any incentives you get just make it better. Whatever you do, like any construction project, get 3 bids from different companies. If there are not 3 companies in your area, you are probably in a poor location for solar. Avoid any company that does a hard sell and tries to get you to commit immediately, or makes you uncomfortable in any way.
Q:How much does it cost to replace a solar panel?
The cost to replace a solar panel can vary depending on factors such as the type, size, and quality of the panel, as well as any additional installation costs. On average, the cost can range from a few hundred to several thousand dollars per panel. It is recommended to consult with a professional solar installer or company for an accurate estimate based on your specific needs.
Q:How many kilowatts? Would it be enough to power my electric heat?Does one panel cost about $2000.?
I doubt it'd supply your heat. Anything involving electric heating uses tons of energy. Also, keep in mind that you don't just need a panel but also a DC to AC converter.
Q:I am doing a report about solar power and I need to know what determines the amount of electricity produced?example: exposure to sun, angle of panel, qualityplease tell me as much as you canmuch appreciated
It depends on what you mean by amount of electricity. Normally that would mean the total energy produced over a given period. In that case, the main factors are ) Efficiency of the solar cells 2) Total irradiation received: incident radiation density times the solar panel area, and the angle of the incident radiation. Item ) is determined by the materials and method of construction of the solar cells Item 2) depends on the location of the panel, both on earth's surface (latitude), time of year, and how the panel is oriented with respect to the horizontal. Altitude of the location can also be a factor. Prevailing weather conditions, number of cloudy days, etc. are important. Independent of these parameters, larger area means more electricity.
