Description:
Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect.
The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon.
The structural (load carrying) member of a module can either be the top layer or the back layer.
Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available,
based on thin-film cells. These early solar modules were first used in space in 1958.
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.
Characteristics of Solar Monocrystalline
I. Solar Cell : High efficiency crystalline solar cell.
Even if under the weak light, the solar module can produce maximum power output.
II. Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase
the power output and mechanical strength of solar module.
III. EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.
IV. AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.
V. Junction box: Multi function junction box with water proof.
VI. Long lifetime: ≥25 years; Less power decrease.
VII. Good performance of preventing from atrocious weather such as wind and hails.
VIII. Resisting moisture and etching effectively, not effected by geology.
IX. The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

- Q: I am curious about how much of the energy that a solar panel of a given size and capacity will produce in it's lifetime, and what fraction of that energy was required to produce it in the first place?
- At present the technology to create silicon solar cells is incredibly energy intensive. It is not logical to compare the cost of oil to the cost of a solar cell because they are not priced according to energy input. Oil has a strong advantage in that it is concentrated solar and geothermal chemical energy that has accumulated over millions of years. The price of oil does not reflect its energy content, but the cost to retreive it. Electrical energy used to produce a Photovoltaic cell is not priced in any proportion to oil. By some calculations it will take about 50,000 KWh of energy produced by the PV cell before it can recover the energy used to manufacture it.
- Q: Can solar panels be used in deserts?
- Yes, solar panels can be used in deserts. In fact, deserts are ideal locations for solar panel installations due to the high levels of sunlight and low cloud cover. The abundance of sunlight in deserts makes them an excellent environment for generating solar energy efficiently.
- Q: What i would like to know is if you were using commercially available solar panels, clustered as close together as possible and spread out on one acre, how much electrical energy is produced? if u can 'translate' this into terms of ( hour of average daylight = powering a ____ for X units of time)
- Solar Power Per Acre
- Q: Im doing a project and i have to persuade some one that solar pannels are great... help ?
- nan
- 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?
- It is tough to answer that question since efficiency is something u pay for thus the price can varies greatly but here is a few web sites you could check out and most would probably be happy to help with any info if you contacted them and the last one has allot of other info that could help like handling waste and water usage in this home
- Q: Do solar panels require a battery?
- No, solar panels do not require a battery to function. However, batteries can be used to store excess energy generated by solar panels for use during cloudy periods or at night when there is no sunlight.
- Q: How long does it take to install solar panels?
- The installation time of solar panels can vary depending on various factors such as the size of the system, complexity of the installation, and the availability of resources. On average, a residential solar panel installation can take anywhere between one to three days. However, larger or more intricate installations may require a longer timeframe. It is best to consult with a professional solar installer to get a more accurate estimate based on your specific requirements.
- Q: Can solar panels be used in areas with high levels of noise from transportation?
- Yes, solar panels can be used in areas with high levels of noise from transportation. Noise pollution does not affect the functionality or performance of solar panels. However, it is important to ensure proper installation and maintenance to maximize their efficiency and effectiveness in generating solar energy.
- Q: How much roof space is needed for solar panels?
- The amount of roof space needed for solar panels varies depending on several factors such as the size and type of panels, the energy requirements of the property, and the efficiency of the panels. However, as a general rule of thumb, a typical 1 kW solar panel system requires around 100 square feet of roof space.
- Q: i just took a trip to florida, they are cutting down anything that doesnt float and putting up buildings. Most of these cost a bundle, bill gates may pay cash for them, but most people will have many payments. Since pools, satellite dishes, and docks if near the water seem to be standard issue, why not a couple solar panels and water heater. It is florida after all, and if you are allready paying a half million or so for a house, what is another 0k gonna mean to you. Why dont they make it mandatory to include these on all new housing and condos and businesses. With that many the price would come down quickly and pay for itself long before the house is payed off and/or florida is flooded due to global warming.
- Solar Panels in housing developments is not being used because it would add $25,000 to $40,000 to the price of the home. Most people in the USA don't understand that after a few years the solar electric panels will start paying them back. It is not just the upfront cost. People would rather spend that 40K on somthing smart like a new corvette. Which has no pay back at all then something stupid like solar electric and helping themselfs or the rest of the world. So if the builders were to add them to the house people would just buy from another builder and the one adding the solar roof tops would just go broke. The State would have to find a way to credit the buyer or buider enough to make it worth it. Is it not more fun to spend millions on finding out where Anna Smith is going to be barried? Or maybe billions on top of billions on War? If we had spend the money on solar that we have spend on Iraq alone we could have put solar on every roof top in the whole USA and had few billion left over. Think about it.. 200 million people in the USA with three to a home would be 66 million homes. It would have only cost 528 billions dollars to put a kWh Solar Electric system on each house in America. But that would be stupid. War makes more money. We don't want Exxon to go broke do we?
