Details Of Polycrystalline Solar Panel (25W—310W)

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.

 

Main Features of Polycrystalline Solar Panel (25W—310W)

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.

Q:question about solar panels....?
They create electricity from light energy provided by the sun....
Q:Why are solar panels grid-like?
Solar cells are semiconductor devices like computer chips. Current manufacturing methods create small squares of semiconductors. Companies are researching ways to make thin film solar cells that can be painted on or manufactured in large, possibly flexible sheets, but so far the technology to do that is still more expensive than making little squares and then assembling them into big panels. That may change in the near future, but I can't be sure.
Q:Help with Home Solar Panel System?
I'm sure that you will discover everything related solar energy at www.okorder.com.
Q:What equation would i need to determine the raise in temperature of water going through a thermal solar panel?
solar panels don't store energy, they only generate it. If you want to store energy you need a battery bank of some kind to get you through the night and anytime the sun isn't shining. If you have a little extra in the budget you might look at a geothermal system for your home's heating and cooling needs. They're highly efficient systems and you can supplement however you like. Whatever you do, though I hope you have a good building envelope in place already. Solar panels are cool, but if you have a leaky house, you're still not getting the best out of your panels. Do the more mundane stuff first. Insulation, windows, and weather-tight doors.
Q:Need Large solar panels. ?
Just google search solar panels or pv panels and you should get a long list of them. That's what I did. Most of the sites selling them will also have the inverters etc that you'll need. Most likely you'll put several small or medium sized panels on your roof - as opposed to just one large one. You probably won't be able to run an entire cafe off of photovoltaic panels, even if you have a bank of batteries. Too many appliances running at the same time. Ask your electric utility company about net metering - you'll buy juice from them when your demand is high and sell to them when your demand is low - IF you can find a sunny day when you're not using juice, but if you have a restaraunt-sized refrigerator you probably won't be selling as much as you're buying. In effect, it won't eliminate your elec bill, just make it a bit smaller. Either way, you may be looking at spending $20,000 to cover the roof with PV panels and your savings won't pay that back any time soon. So, PV is not so great for a business. Much better for a home where you'll be at work all day the only appliances running in your house is your frig. Whatever you invest to solar your house will be repaid when you sell it, meanwhile you'll reduce your bills dramatically, especially if you convert all your indoor lighting to LEDs. On the other hand, the Googleplex, Google's office building full of computers, covered their roof with pv panels and claim to have reduced their monthly bill by /3. BUT, that's a huge building with lots of roof space.
Q:I NEED HELP WITH MY SOLAR PANEL SYSTEM PLEASE HELP?
I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
Q:Maintenance of Solar Panel?
panels need full sun. any shade reduces out put. leaves left on them will cause the individual cells burn out. they nneed adjusting every season, an washed with a soft cloth once a year.
