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:Are photovoltaic cells the same as solar panels?
Yes, they are the same thing.
Q:Information on making solar panels?
I doubt that you are going to want to learn how to dope your own silicon wafers, add contacts and laminate them into PV panels.  I also doubt that you're going to even want the various chemicals to make e.g. cadmium-based cells anywhere near your house (cadmium is a very toxic metal).  In other words, making your own solar panels is not an at-home project. You can buy solar panels based on cells of several different types.  A link to a Pricewatch-like website for current prices on solar panels is below.  Mounting panels to roofs or pole mounts, running conduit and wires, and installing battery banks and inverters are within the capabilities of skilled laypeople. More data at the links. Edit:  I am reporting all of Agua-Luna's cut-and-paste pieces as spam.  I encourage others to do likewise.
Q:Solar panel battery charging?
it depends how big the panel is. a small trickle charger (like a 2W panel with built-in diode), just connect + to + and - to - (parallel) to trickle charge the battery. The diode will keep the batter from discharging through the panel when there is insufficient sunlight. for a large panel (like a 220W 24v panel), you best go through a charge controller. the charge controller has 2 leads for the solar panel input, 2 leads for the battery connection and 2 leads for the 2v load. just follow the instructions to connect the panel and battery to the controller, and MAKE SURE YOU USE THE REQUIRED FUSES. very straightforward stuff -- just RTFM
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 should the voltage be on a small marine solar panel?
If it's only reading 0.2 volts, then the panel is burned out. What you can do is look for a nameplate on the panel, then try to look it up on the internet. Hopefully that will say what the voltage is supposed to be. You are right in that a panel intended to charge a 2-volt battery should read about 8 volts open circuit out in daylight, even if it isn't pointing straight at the sun. Is it a flexible rubber panel? Those are notorious for dying after just a couple years.
Q:How to connect or use Solar Power Panels?
You will need help with this. Panels may or may not be 24 volt. If you can find a name tag, you can find out from the manufacturer's web site. Some folks hook them all in parallel. Mine are in series, to create 480 volts. the reason for going to higher voltage is to reduce power loss in the wiring. Even then, I used a wire size larger than recommended. The frames want to be interconnected, and wired to ground. The live conductors connect through disconnect switches to an inverter. The inverter is sized to the output of the panels. Where the utility allows net metering, the inverters are connected through a disconnect switch to the grid, which of course also feeds the house. Assuming you are on the grid, you will not need batteries. If outages severely impact you, you can have batteries. Counting against them is that they are costly, and use part of the power you generate, just to keep them charged. If you have batteries, it is usually best to rewire circuits so noncritical circuits are disconnected during outages. Leaving perhaps minimal lighting, fridge, freezer and critical medical circuits. Learn all you can from the Internet (try solar panels), and from the green search box above. Be sure to see if your state has a rebate program, and the conditions which it requires.
Q:how do i build a solar electric panel for my home?
Dear Matadora, Very good, good, good step to change your home electric supply to solar cell, because in long run, solar cell is cheaper. First you have to consider Power need for your house, eg. 200W, then you go to sellers and choose one with lowest price but best quality. After that you should assemble/attach your solar panel in place that gets most Sunlight, most probably in your roof. Attach them tightly, avoid burglar. Original solar cell current is DC. Current from solar cell placed first in several car batteries, so you could use electricity in night either. After that if your home appliances use DC, you could directly connect your appliances to batteries. But if your appliances need AC, current should be converted first from DC to AC use DC to AC converter. Car battery used to have 2 Volt DC. So if you need 220VAC, after DC converted into AC, then passed through transformer to increase voltage. Thank you very much Matadora.
Q:How big of a solar panel system would I need to get ?
First find out from your electric company whether they allow grid tie systems. IF so then they can help you figure out what you need.
Q:Blocking diode for solar panel?
At least a 2 amp diode. rated above the 2 volts that are commonly found on the market. A blocking diode must be able to stop a higher current and voltage than the panel maximum. A diode will work on any voltage and current lower than it rating.
Q:Will a 2W, 2V mono solar panel power up a laptop battery?
I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
