Introduction of Solar Polycrystalline Series
CNBM Solar photovoltaic (PV)module 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.Poly- or multicrystalline silicon(poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified. Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient. US DOE data shows that there were a higher number of multicrystalline sales than monocrystalline silicon sales.
Characteristics of Solar Polycrystalline Series
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.
IVAI 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. .

- Q: Hello Yahoo, I am doing another one of my wacky inventions however I need something that will give me 2V of power!I don't want to connect loads of AA batteries into a battery holder as this shall run out quickly and become expensive in the long run, I don't want to carry around a big car battery either.I have been searching around on OKorder .uk and found some Solar-Powered 2V Trickle Chargers. These say they shall work on cloudy days (which is perfect as the majority of the time that is all we get!) but could I use it as an independent power source?If I attached the thing I want to run to the solar panel will it supply it with 2V of power?
- How many amps will you need? Remember v x a = power. The way those trickle chargers work is by sacrificing some amperage to get up to 2 volts. If you can invent closer to ~3V range that solar cells naturally produce thing will likely work better. A sign or a light that doesn't need a lot of power will work. Automobile battery packs might take a month to charge. Solar-Powered 2V Trickle Chargers are used mostly to keep things like boat batteries in storage from discharging, not to charge them.
- Q: I need to power a series of meraki wireless repeaters that plug into a standerd wall outlet. consuming 5v or .08 amps However I need this in a remote location (like out in the middle of nowhere) Using A solar panel as power supply and a battery to store the energy but, how and what do I use to convert the energy coming from the solar panel to the battery and the batteries power supply to match the needs of the meraki wireless repeater? How do I make this as compact as possible? Do I need a ac/dc converter? or dc/ac converter? Any suggestions or solutions would be great !
- Search the web for some of the inexpensive solar Cell Phone Chargers. They can be hooked in series or parallel as needed to get you teh voltage and current needed. The 80mA is not too tough, thats not much current. Suggestion is to use a battery that is constantly trickle-charged by the solar panel. This will assure operation on a cloudy day or at night. Another strange source for solar panels and solar charge systems is, believe it or not, Harbor Freight Tools. they are on the web as well as have stores all over.
- Q: Does anybody know if there are any courses for solar panel installation, and/or what trades you need for this position?
- What you ought to recognize will depend on WHAT sort of installations you're going to be operating with. In regular, for business you wish to have fundamental mechanics and wiring. For house, you may additionally want a few carpentry, roofing, preserving structural integrity, plumbing, and so on. In side it additionally will depend on what sort of sun installations you're doing, (vigour, air warmers, water warmers, and so on.)
- Q: I'm re-doing my roof. Is it workable?Can I get a government grant or something to put solar panels on my roof?I know they did something like that for windows.
- solar panels are only about 20% or so efficient right now but you get great tax break in the US --- mostly.. wish you well... ps not that cheap but most companies installing these systems will supply with all grant papers for free.
- 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: How much does it cost to replace a solar panel?
- The cost of replacing a solar panel can vary depending on several factors such as the size, type, and quality of the panel, as well as any additional installation or labor costs. On average, the cost can range from a few hundred dollars for a small residential panel to several thousand dollars for a larger commercial panel. It is always best to consult with a solar panel installer or supplier to get an accurate estimate based on your specific needs and requirements.
- Q: How do solar panels impact wildlife?
- Solar panels have a minimal impact on wildlife compared to other energy sources. While some concerns exist regarding the potential for bird collisions and habitat disruption during installation, these impacts are relatively low and can be mitigated through proper siting and design. Additionally, the reduction in greenhouse gas emissions achieved by solar panels benefits wildlife by combating climate change and preserving their natural habitats.
- Q: I have a panel that quot;deep breatheproduces at 4% efficiency, what can it power, It's about 4ft by 2ft
- I sincerely doubt that you have a solar panel that is 4% efficient at converting sunlight to electricity.
- Q: The ancients used skylights for light in lieu of electricity. Light was used for drying, even cooking foods and drying clothes. Solar clocks/sun dials were once popular but now we have battery operated clocks. Where have we tapped into any of these resources since the outdated solar clothes drier nicknamed the 'clothes line'?
- For simple starters, look to the gigantic strides technology has made due to the science of the laser. Its light power at its most extreme.
- Q: Do solar panels require a specific type of inverter for converting DC to AC power?
- Yes, solar panels require a specific type of inverter known as a solar inverter to convert the direct current (DC) power produced by the panels into alternating current (AC) power that can be used in households or fed into the electric grid.
