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:I'm have a DIY solar panel and wanted to use micro inverters?
It won't work for several reasons. ) Enphase needs 24V modules, you made 8V ones. The voltage is too low to turn it on. 2) Only UL listed (or similar lab) panels are allowed to be connected to your house electrical system. Even if you did get them to work with the Enphase, you won't be able to get the system inspected, there is no way it would be allowed to be turned on by the electrical inspector nor the electric company. 3) If you got by obstacles and 2, and you had an electrical fire in your house, it is highly likely your insurance company would not pay you for it, as you used non-UL panels. DIY panels are fine for little back yard projects, but when it comes to your home, buy real ones. The price has dropped so much in the last 2 years, it's not worth it to mess around.
Q:Can a solar panel work with an inverter?
Solar panels output a very small amount of current. Even though you're getting 2V from the panels, you aren't getting enough amperage to power even the inverter itself, let alone anything plugged into the inverter. Car batteries are able to be used with inverters because they can crank out enough amps to power the inverter and whatever is plugged into it. Inverters only step up voltages and change DC to AC. They do not increase power (wattage) potential. If you want to plug in a 20W appliance into the inverter, the 2V source must be able to deliver 20W of power regardless of voltage. In pretty much everything solar powered, the panels are used in conjunction with batteries. The solar panels slowly recharge the batteries. The batteries are where most of the power comes from. Nothing is driven directly from the solar panels themselves unless the power requirement is low enough, such as a calculator. Solar panels will have an output rating in watts (W). If the wattage of your inverter plus whatever you plug into it is lower than the panel's output rating, then it can power it directly, provided you have 00% light input into the panel.
Q:How do you install solar panels?
You need to determine how many solar panels will produce the amount of power that you consume now. You can check your bill for the number of kilowatt hours (power) you will need. There are websites that will help you calculate the intensity of sunlight in your area. There are other websites that will help you determine the average daily sunlight. The sf of your house has no importance. The amount of power you use is independent of the size of your house. You hook up solar cells in series to increase voltage. You hook up solar cells in parallel to increase current. Power is voltage multiplied by current. Most modern houses are supplied with 200 Amp service at 240 volts AC. The solar panels produce DC power. The grid in most places provides AC power. So you will need a AC/DC power converter. The sun does not always shine so you will need a storage battery bank capable of storing all the power you will use at night.
Q:How would you build a Solar Panel that can convert Sunlight to Energy, just being on your house roof?
there is a website that sells a book for $40 thattells you how to do it cheaply check it out just google earth4energy
Q:Has anyone had roof problems caused by rooftop solar panels?
Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
Q:What factors effect the amount of electricity produced from solar panels?
irradiance in watts/meter^2 (000-800w/m^2 depending on air quality) COS of angle to the suns rays efficiency of the panels (usually about 5%) age of the panels(one dead cell can drop an entire panel from the array) how dirty are the panels (dust, bird poop, leaves, shading) efficiency of the inverter (usually about 90%) All of these factors affect the amount of electricity produced. One other consideration is that in areas of extreme hot and cold the band gap of the silicon is changed.
Q:Why do people use solar panels?
I doubt the immediate economy has much to do with it. Solar panels require long-term investment, so in hard times, someone having trouble making ends meet is not going to be buying solar panels, when they could be buying food. It's like if someone has a gas guzzler, if they get laid off, they're not going to spend their savings on a new, fuel efficient car, even if it saves money in the long term. However, it's generally the more wealthy that install solar, and they're not impacted as much by a slow economy. Human nature being what it is, I doubt many people install solar to save the planet. There will be some, but I suspect most are interested in the long-term financial savings. I'm kind of unusual, in that our panels are break-even financially at best. The main reason I put them up was for the fun of learning and doing it.
Q:i am asking about the solar panels?
First of all, make sure that you are taking readings in the dark (with the solar panel indoors and covered). 0.433 is a reasonable forward voltage for a Schottky diode. Ideally, it diode should read open one way (possibly OL for your meter), and 0.4 the other way. If it's reading OL both ways, the diode is bad. You can either unsolder it or cut it out and verify that it is bad.
Q:Question about commercial solar panels?
they are in a position to be in case you're properly knowledgeable and experienced of their assembly and working function, offered you acquire the comparable severe high quality grade cells and do perfect assembly. probability is robust although that your first a number of could be in hassle-free terms somewhat below par till you rather get the carry of it and strengthen into properly practiced purely because of the fact the pros are. Does take a important volume of grunt paintings although so determine if it rather is great use of a while or in case you will do greater beneficial to earn at your prevalent paintings and pay a professional to do this which they do superb.
Q:powering an imaginary city! (need solar panels!)?
There are panels made up to about 250 watts. You string them together in series/parallel to get more power. Depending on your average insolation, a 250 watt panel caqn produce anywhere from a kwh/day to two kwh/day (averaged over the year - it's less in the winter and more in the summer and can range from 0 to three kwh/day). Powering a city also requires energy storage for nightime or cloudy days. The cost of this can exceed the cost of the panels by a factor of three. DK
