Solar Polycrystalline Series Panels

Introduction of Polycrystalline Solar Panels

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. Polycrystalline 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.

 

Characteristics of Polycrystalline Solar Panels

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.

FAQ

 

We have organized several common questions for our clientsmay help you sincerely

 

1.    What’s price per watt?

A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.Normally Speaking, the poweroutput from 250-300W, the FOB Price is $0.6 Per Watt. The detail price need to negotiate according to further situation.

 

2.    Can you tell me the parameter of your solar panels?

We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.

 

3.    How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

Q:how much money can I make a year for the electricy I sell from a solar panel?
call your power company and ask them how much they pay for each kWh you feed back into the grid (the price may vary for different times of the day). then multiply that by however much electricity you are producing.
Q:_How many solar panels needed to light up a whole house?
It's not really the solar panels that power the house, they charge a battery bank and there's an inverter that jumps the battery power up to household current level. If you start getting into more expensive systems, they can sense when the batteries are full and start diverting power into the local electric grid. Some places the electric company is required to pay you for generating current, other places tell you tough luck. I suggest looking on OKorder or something at some of the home solar kits on sale there and look at how large a house they are rated for to get an idea of how big a system you're going to need. I don't know if you have access to the power bill history of the house you're getting in Dubai, but the power company there might be able to provide you with a history of average kW hours the house consumes. A 2400 sqft house with a gas stove and a gas water heater and wood heat is going to consume far less electricity than a house with all electric appliances and the consumption history of an individual house should reflect that so you can buy appropriately.
Q:Home made solar panel?
It okorder.com/
Q:Are solar panels a viable option in IL?
You can do solar anywhere and yes, they're a viable option in IL - as they are where I live - in Maine! We get snow and also lots of low light days in the winter. It's not as easy as say -having solar in New Mexico (self-identified as the solar capitol!) but - you can still generate a nice amount of electricity with your solar panels on a nice day in IL - and they're fine in the snow.
Q:How to make 2V 4.5A solar panel from solar cells?
The simplest way to use these panels is simply to connect the panel to your battery, with a diode in series to prevent the battery from discharging through the panel (no sunlight condition). Just connect the battery for the required charge time then disconnect it. Full sun is required, no shadows on the solar panel! ---------- .
Q:How to build a small SOLAR PANEL that will light a 60 watt light bulb?
Making your own photovoltaic (solar electric) panel is a nontrivial matter if you want to get 60 watts out of it. If this is a science fair project, there are some possible paths that I'd suggest: ) Make your own cupric oxide panel. With just one square foot, you can harvest perhaps 0.5 mW in bright sun - enough to power a solar calculator; -or- 2) Buy a panel to light your 60 watt bulb. You could probably get away with a panel that is 6 square feet, but would use a car headlight as the lamp. If you wanted to light a regular household bulb, you would need electronics to step up the voltage, and you would lose a sizeable fraction of the energy just in the conversion. -or- 3) Buy broken solar cell pieces, or individual solar cells, and solder them together into your own panel. This is a LOT of trouble, and is a finicky process to get working and keep working. And it may not end up being cheaper than buying a ready-made panel. But you can claim that you made it! By the way, crystalline silicon panels are in the ballpark of 5% efficient, and a 3' x 3' one would produce in the neighborhood of 20 watts.
Q:How do you store energy using a solar panel?
Solar panel is not a energy storing device, rather it converts light energy to electrical energy and this energy either can directly used to run instruments or can be fed to battery for storing. The working of the solar panel is like the inverse action of a LED, i.e. a LED converts electrical energy in to light where as a solar panel converts light energy in to electrical energy, basically it is a P-N junction diode.
Q:How would you connect a solar panel to a fan?
Panels are rated nominally, and you can look at your fan to see what the ratings for the fam are to determine sizing of the panel. Current multiplied by the volts (rated) gives you the wattage of the motor- just use this as a guide for sizing the panel. You do want a little more power from the panel than the motor draws for purposes of starting the motor and for having the fan operate at lower sun angles as well. You can add a battery if you chose, but it is not a requirement. Just treat the leads of the panel like those of a battery red (+) and black (-) just connect those to the fan, if you match color for color, no problem. If the markings are not present and no wires are on the fan, try it one way, if it is the wrong way- reverse them. AC operated fans will require an inverter to convert the DC to AC. These draw a certain amount of power as well. In general the same rules of thumb apply. It is just easier though to stick with a DC motor.
Q:how can i charge a 2 volt car battery(lead-acid)with a solar panel?
Q:Help choosing solar panels?
first okorder.com/ example: house roof is 20' x 20' 20' = 240, so sq. inches of roof is = 57,600 say rain fall for your area is 3 per month on average. 57,600 x 3 = 72,800 of rain collected. Using the conversion chart link above, that many cubic inches of water = 750 gallons of water free per month. Look at your water bill and see how much you use. Solar panels take on average 2-20 yrs to pay themselves off, just in time for them to be replaced. Paddle wheels go on for just about forever. We still find large paddle wheel mills in the USA that are over 200 yrs old, and still functioning.
