Product Description:

Solar Polycrystalline Series

 

 

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:Advice on Solar Panel....................................?
The thing is having a solar panel is a great advantage when you want to have save a money but it doesn't necessarily means that it will cover up your expectations. Expand your knowledge and learn from a renowned solar company about the Best Solar Panels. Visit our site and contact us today!
Q:solar panels disconnected from battery?
Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
Q:Solar Panel Help? Beginners?
You should have your dad check out this site. Easy to learn and very effective. bit.ly/solar9WXBrw
Q:Tell me the guidelines for making solar panels?
What they consist of is little bitty silicon particles that transport the electricity through thermal conduction. The sun's rays activate it and create a circuit. The advantage of solar energy is that it's clean and renewable. At this point in time, though, it's inefficient because you only get about 0 to 5 percent output. Also, we don't have the technology right now to save solar energy and store it into batteries so it can be used at night.
Q:0W solar panel can use on what?
No. The way to set it up is to store the power generated by the solar panel in a battery, then use the battery to power your lights, radio, etc, when you need the power. A standard deep-cycle marine battery is typical for panels of this size (WalMart for approx $90). A 0W panel will generate between 30 50 Watt-Hours of power over the course of a day (May-Aug weather-dependent), so this would equate to running a laptop for -2 hours, or a 0W CFL light for 3-5 hours, or a 20W stereo for .5-3 hours, etc. I find it is much easier to speak in terms of watts. Divide the watt-hours by the watts of the appliance to get the number of hours it can run. Hope that helps!
Q:What about solar panels?
This is a site that can help you estimate the size and number of panels that will power what you intend to provide for. There are plenty of sites selling the panels, so compare prices. Also, check whether your state is offering the rebate like the state of CA is and what the restrictions, terms and conditions are. Even with the rebates they are very costly, so be certain to calculate the pay off period for your application to see whether it is a cost efficient option for your energy usage.
Q:How Much Do BP Solar Panels Cost In The Wholesale US Market?
Wholesale prices for BP solar panels range between $335 for the 40 watts panel to $835 for the 70 watts panel. Here's a brief listing of wholesale prices for BP solar models: - BP340J solar panel (40 watts) @ $335 - BP350J solar panel (50 watts) @ $37 - BP375J solar panel (80 watts) @ $504 Right now I'm getting a series of 50 watt (7.5 volts) panels installed in my house. It's a start to reduce dependence on electricity bills and try get some tax rebates as well.
Q:How to build a solar panel?
To build an effective but cheap solar panel, you need some expert advice. I recommend you get your hands on the comprehensive e-book and video instructions by Michael Harvey. His guide is very easy to follow and it will help you make a complete solar power system for less than $200. He also teaches how to make windmills. I hope this helps!
Q:2V Solar panel directly to 2V inverter...and restult.?
. A 5 WATT panel can NOT power a 300 WATT inverter. 2. IF using 2 volts, then you need a 2 volt battery in the circuit as well. Panel charges battery which powers inverter. When the inverter pulls more power than the panel puts out, it gets it from the battery until the voltage drops low enough to shut down the inverter. NOTE: SOME cheap units do NOT have protective circuitry, and when the voltage drops, the current rises and burns them up.
Q:Please differentiate b/w mono & poly crystalline silicon solar panels.?
In the practical sense, the differences are trivial. I'd buy on price per watt, unless space is at a premium (it isn't for most installations).
