Introduction of Poly solar panels CNBM
Polycrystalline Solar Panels 305W 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:Is it really necessary to make solar panels that expensive?
- First Solar recently announced that their costs to produce panels dropped below $ per watt. I don't know how much of that is accounting tricks. Of course, that doesn't mean that they would sell panels for that price - any capitalistic company is expected to drive the price up to what the market will bear. Crystalline silicon panel producers are coming in at about $2.50/watt right now for the best of them. But again, the selling price is what the market will bear.
- Q:i really need to know howbecause im building a solar powered car for science fair :]thank you!
- Hehe, if you want to build your own solar panel that looks like what you see on buildings, etc, you will probably need to be a multi-millionaire. Here is a quote from the first link in my sources list: The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon, and require huge factories, high temperatures, vacuum equipment, and lots of money. But fortunately for you, there is a cheap way to make a solar panel yourself (see first link). I love the scitoys website, but I am not quite familiar with this particular experiment. It looks like a science fair project in itself! It also doesn't appear to put out nearly enough power to run even a small solar car. What I would recommend is buying a compact solar panel from Radio Shack or some other electronics store that you may know of. Type in solar in to the Radio Shack search box. The first item on the list may be useful to you (the solar panel battery combo). I am just guessing, though, since I don't know any of your requirements (voltage output, power output, size, etc). Also, buyer beware. This particular product has a pretty bad customer review... but then again, I find that people are more inclined to leave a bad review than a good one. Good luck... -Ubi
- Q:I paid for an appraisal and the home was valued at $25,000. The problem I have with this is my house is equipped with solar panels. I paid about $25000 for them. A comparable house sold for $225,000 4 months ago. Same amount of rooms, bathrooms, square feet, lot size and curb appeal (landscaping). But no solar panels. Home prices in my neighborhood have also gone up. I would like to know if there is any way I can dispute this as I feel I just wasted a lot of money on a incorrect appraisal.
- Zillow appraisal is useless and not at all important. If you are selling your home then the solar installation should give you some advantage, depending on how much you are still paying for utilities. The only appraisal that matters is the one a buyer gets to lock in a mortgage. Nothing else matters.
- Q:I have to get a lot of information on how solar panels are developed and distributed in America because I have to do two pages on this. Please help me get information in this I really need it!! Thankss...
- The first link below is one of the best sites for recent news about solar panels. You should be able to find stories about solar panels under development today. A little bit of the history: Solar panels have been around for about 50 years now. They were first used to power spacecraft. Solar power for domestic use started to develop rapidly in the 970's during the first oil crisis, but as energy prices fell in the 980's solar development slowed. Most of the large solar panel makers were purchased by large oil companies who seemed not to be too interested in solar. In the late 990's as concerns about both Peak Oil and Global Warming grew there was renewed interest in solar power and a number of new companies were started to develop new kinds of solar panels. Many of these new companies have grown larger than the older solar companies still owned by big oil companies. Over the last 7 years or so growth in the solar market has been explosive with a compound growth rate of almost 40% per year. In 2005 the solar industry for the first time started to consume more silicon than all other electronic industries combined resulting in a world wide silicon shortage that is still with use. New silicon refineries are coming on line and the shortage is expected to diminish by 2008 or 2009. Check out the two links below. They will help you a lot.
- Q:I am building a solar car for the energy wiz competition and I was wondering how I could possibly get my solar panel to shift sideways
- having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
- Q:How do solar panels affect the property's resale time?
- Solar panels can positively impact a property's resale time by making it more attractive to potential buyers. With the growing demand for sustainable and energy-efficient homes, solar panels can increase the property's value and decrease the time it takes to sell.
- Q:Can solar panels be installed on a winery or vineyard?
- Yes, solar panels can be installed on a winery or vineyard. In fact, they are becoming increasingly popular in the wine industry due to their numerous benefits such as reducing energy costs, promoting sustainability, and mitigating carbon emissions. Solar panels can be installed on rooftops, carports, or ground-mounted systems in areas where they can receive maximum sunlight exposure.
- Q:Can solar panels be integrated into windows?
- Yes, solar panels can be integrated into windows. These solar panels, known as solar windows or building-integrated photovoltaics (BIPV), are designed to replace traditional windows while capturing sunlight and generating electricity. They offer a dual functionality of providing natural light and generating clean energy, making them an innovative and energy-efficient solution for buildings.
- Q:a fiber optic network could distribute solar energy from warm states to the rest of the country. Using a Federally created program,the energy would be used through a trust program to benefit all of our citizens equally. It would create thousands of jobs and help us with our dependence on foriegn oil supplies. This is no different than work programs created by the Feds during the 930's depression era.
- Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!
