Item specifice:

Material: Monocrystalline Silicon Max. Power(W): 50 Number of Cells(pieces): 36
Size: 650×550×30mm

Product Description:

Solar Monocrystalline 125mm Panel Series(20W-25W)

Product Description

1.High efficiency crystalline silicon solar cell. Even if under the weak light, the solar module can produce maximum power output.

2.Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

3. EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

4. AI frame: Without screw, rner connection. 6 holes on the frame can be installed easily.

5. Junction box: Multi function junction box with water proof.

6. Long lifetime: ≥25 years; Less power decrease.

7. Good performance of preventing from atrocious weather such as wind and hails.

8. Resisting moisture and etching effectively, not effected by geology.

Q:How does solar panels work?
Solar panels are built with light-sensitive panels. These panels soak up the energy from the sun's light. This energy is changed to electric power. This power is stored in batteries to use whenever / wherever it is needed.
Q:how much do solar panels cost?
The silicon ones(last 5 to 25 years) run about $4-$5 a watt the amorphous (thin film) a little less (may last 5-0 years). If you use megawatt hour (000 kilowatt hr) a month you will need at least 3000 watts minimum. Therefore if your electric is .0 per kilowatt hr( $00 per month) the payback is around 25 years once you add the batteries plus inverters(batteries $50-$00 each)(synchronous inverter $3000 to$20000)(ie $5.00/.0=50 months at optimum output).Figure (depending where you live) probably only 50% so break even is usualy about 20 yrs.Ie you pay 20 years electric bill and hope nothing breaks(insurance not included) then you can start saveing money.

Q:Solar Powered Propeller?
Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.

Q:Benefits of Solar Panels?
The solar panels that we all simply would think are the greatest thing ever are very, very expensive and require strip mining of huge areas of land to make. For several million dollars you can buy what usually is mounted as power source for space satellites upon your roof. This 2'x2' panel and a barrage of battery storage takes care of all the electrical needs you could ever have at home. But this profoundly environmentally destructive technology is not what you had in mind, I'm sure, but is what has been around for quite some time now. It's been a challenge to make solar panels without using complex chains of excited rare metallurgies, but we seem to be getting better and better at it--but I trust others should help you with the practical, now that you know the best panels are not best for us at home.
Q:Will a 3w Solar Panel Charge A 55ah Car Battery?
To charge a 2V lead acid battery, you pretty much have to put almost 24V across it and it's only 50% efficient at charging so if your solar panel does put out 3W, you can expect 3/24/2 or /6th of an amp in usable charging. Therefore, from a flat battery, it would take 55*6 or 880 hours to charge the battery. If you assume about 6 hours of usable sunlight per day, that would be 47 days not taking into consideration the normal leakage that lead acid batteries have. It's quite likely that the leakage rate will be greater than the charging rate and the battery will never charge. You'll need a bigger solar panel.
Q:SunPower Solar Panels?
You should get the highest efficiency at the lowest price. Typically, the Sunpower brand panels have the industry best 23% efficiency depending on the model. You have to look at the specification very closely and if you don't see it, ask. There are two types of solar cells Polycrystalline and Monocrystalline. Polycrystalline cells are inferior to Monocrystalline. You will also see that different kinds of panels have different output voltages.Since you will be wiring your panels together and connecting them to either a power inverter or a charge controller (if you have battery backup), you need to make sure the panels and controller work together for maximum efficiency. Be very careful when engaging an installer especially when they are trying to sell you the equipment too. Mostly, these are not engineers and you will end up with whatever they have in stock without regard for the most optimal design.
Q:can solar panels be refurbished?
Often they get scrapped out or landfilled. Photovoltaics cannot be refurbished. Solar collectors for heating air or water, could be concievably refitted with new clear covering, new insulation, and new heat exchanger, but unless it was a custom installed system you are trying to refurbish, it is more time economical to construct new ones, or to buy new ones.
Q:I would like some info on Solar panels and Wind Generators...please?
You may have to put a snow roof over the wind generator to keep it working. A solar hot water system might be hard investment where you are but it could work if it's designed right. Check out the solar companies in your area for ideas.
