Details Of Polycrystalline Solar Panel


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. .

Product Description of Polycrystalline Solar Panel


CNBM Solar Polycrystalline Series (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.

Q:Solar Panels, kw per hour or day ?
That means if you stick a watt meter on the output when there is maximum design sunlight on it you will get kw. If you shine the maximum design sunlight on it for hour then you get kw hour of power. In one day you get 24kw hours assuming you can get 24 hours of maximum design sunlight. Your home electric bill is typically in kw hours. At the macro level power is traded at megawatt hours.
Q:background of solar panel?
Hint: It's behind the foreground.
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:Increasing Solar Panel Efficiency?
Even the angle of a solar panel can increase it;s out put, if you point it towards the south, it will receive more light (or towards the light source if it is an artificial source) mirrors can also be place and angled around solar panels to gather and reflect more light to the panel, this is often done is solar water heating, but would work with a panel as well. Over all, solar panels are very efficient, it's our way of catching light that isn't.
Q:Solarcity free solar panels?
What that means is free, considering the cost of electricity saved, i.e., no additional out-of-pocket costs. It could still be a good deal. For example, your bill is now $200 a month. Maybe the solar drops your bill to $40 a month, and you pay $50 a month to SolarCity for the duration of the lease. One thing to remember, though is that only works if your bill drops to $50 a month or less. If the panels don't produce enough, you may end up paying a $60 electric bill, and still $50 to Solar City, for the duration of the lease. They will also count on getting your federal tax credit, so I don't know how that works into the price. Also, they must make money as a leaseholder or financer, so it shouldn't be as good a deal as simply installing panels and paying for the whole thing up front. We installed solar electric in 2006, and it's still working great. If I had to do it over again, I think I'd get solar hot water first, though.
Q:who would win in this battle?
hmmmmm trees would squash em and solar pannels would electric cute em............... :)
Q:Are our scientists making solar panels all wrong??
If the panels are deployed at outer surface of atmosphere then white will reflect the sun light to outer space. If the panels are deployed at earth surface, inside the atmosphere, most of the reflected light will be bounced back to earth by the atmosphere. For the solar panels we are talking about, they need to be dark color to absorb light and turn into electricity.
Q:DIY home solar panels?
Did okorder.com/ . This will absolutely save yourself!
Q:how many solar panels do I need for my house if in average i consume 880 kwh?

Q:How to install a solar panel system?
If you are grid-tied, then a standard solar electric system will always feed back into the grid if you are not utilizing more power in your home than is being generated by the solar panels and inverter system. It is possible that a grid isolation device designed to prevent direct back feeding is available, but haven't heard of one in common use. New laws in most areas of the US are now mandating that utilities allow grid-tied alternative energy systems. Double-check you local laws. Sometimes you can't take the utilities word for truth--most will automatically say 'no' and will only relent when you show up with the law in hand. Unfortunately, some utilities have figured out another way to shut down alternative energy pioneers--they demand multimillion dollar insurance policies covering damage that their equipment could sustain from your little PV system. Technically, they are still in compliance with the law, they just make it impossible for a homeowner to meet their requirements. If you are getting the runaround, go to your state representative for help. It's amazing how contrite those utility people can be when a state senator (or even US Senator) has just sent a letter asking them why they are stonewalling a law-abiding and well-meaning citizen. Good luck, and don't give up!
