1.Structure of



Polycrystalline Silicon Solar Panel for 250W

I. High efficiency crystalline silicon 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, rner 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.

IX. The certificate issued by international authority: UL, TUV, IEC, CE.

5.FAQ of Solar Module

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

what price for each watt?

it depends on the quantity, delivery date and payment terms,

what is your size for each module? can you tell me the parameter of your module?

we have different series of panels in different output, both c-si and a-si. please take the specification sheet for your reference.

Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Yes, we can, we have two companies for solar region, one is CNBM International, the other is CNBM engineering Co.

We can provide you not only the solar module but also Solar Cells, the off grid solar system, we can also provide you service with on grid plant.

What is your warranty system?

 Our product  performance guarantees for 25 years

12 years guarantee for workmanship

Timeliness of delivery

Quality Products certified (TÜV, UL, CE, ISO)

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:0 Watt solar panel question?
It will be less than a trickle charger on the battery. It is about .85 amps at 2 volts dc.
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:Joule Thief vs Solar Panel?
Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
Q:can i make a solar panel out of aluminum foil?
Presumably you plan to create a focused parabolic reflector and have it oriented to heat the bottom of a pan. It will obviously need to be larger than the pan in order to gather sunlight outside of the pan's shadow, as well as gather and concentrate enough light onto the bottom of the pan to heat its contents. If you use black paint on the bottom of the pan, make sure it's high temperature paint (available at auto supply stores, often used to paint engine blocks and exhaust manifolds). Yes, a cover on the pan will make it hotter.
Q:when building a solar panel should the diode be on the positive or negative side?
Bypass diodes would be in parallel with groups of solar cells in a panel. For example, if a module has 72 cells, maybe every 8 cells, there will be a bypass diode. A bypass diode does nothing except salvage some of the energy from the panel if some of the cells are shaded, and others are not. Or, if you have multiple panels in a series string, the bypass diodes allow the other panels in a string to continue to contribute energy when one panel is shaded. Unless you're forced to put the panel(s) where there will be shade during the day, the bypass diode does not matter. Commercial panels all include bypass diodes. Blocking diodes are generally NOT included on commercial panels. If you're going to a grid-tied inverter, you probably don't need one. There are stringent regulations on how panels must be grounded, and whichever side of the panel is grounded should not have a blocking diode. NEC regulations call for a continuous ground to earth. For example, if you have negative ground on your system, the blocking diodes, if any, should go on the positive terminal of the panel. By the way, if you're in the US or Canada, do understand that a home-built panel will not be legal to connect to a grid-tied system. And a grid-tied inverter that plugs into the wall will also be illegal. I'm only saying this because I don't want you to get hurt, or your house to burn down. Line power is nothing to be trifled with.
Q:Where do I find solar panels?
You can start as small as 7,500. It all according to how much you want to run off solar and your Environment. You can move into Solar slowly as the technology Improves every six months or so.
Q:Has anyone used portable solar panels for home use?
from what i have seen and heard the portable panels you are talking about are not big enough for home use unless you create a specific outlet to use them on such as one for cellphone charger or other small use items. Just my semi-educated guess.
Q:What are solar panels made up of?
Solar panels (aka photovoltaic panel) are most often made up of thin wafers of crystalline silicon or cadmium telluride. As photons from the sun enter the photovoltaic cell, electrons are freed from the substrate when are then collected by wires that run throughout the panel. And as we know electrons=electricity!
Q:Solar panels on the roof?
You dont say where you live? you need to consider average sunshine hours. There are some sites on the net that will work out for you what percentage of nameplate capacity you could expect to receive for different areas. Usually the capital cost wont be paid off for at least ten years, so money wise you would do much better by investing the cash. I once asked a guy (climate warmer) whether his solar panels had paid off or would do in the future, his answer was no but it was the right thing to do morally.
