Characteristics of Polycrystalline Solar Panel

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. .

 

Standard Test Conditions of Polycrystalline Solar Panel

The opto-electrical specifications shown below are stabilized values being measured at Standard Test Conditions of multicrystalline silicon Solar Panel, Irradiance: 1000W/m2, Spectrum: AM1.5 at 25°C, The info below is subject to manufacturing tolerances. Where appropriate minutes of measurement are available and are used for the dimensioning of the installation.

Currently,We have 250w-300w solar panel stocks in Both West and East Coasts made in Vietnam,India,Korea,Malaysia and Japan.Meanwhile,we also arrange production line in Wisconsin,USA.If you're interested,please contact us soon.

Thanks for your time.

 

Q:I'm looking into buying solar panels, there are all kinds of ranges of energy output...but my question is, when ti says...say 50 watts of power...does that mean 50 watts a day, an hour, a minute, what?
A 50-watt rating means the panel will produce 50 watts as long as the standard conditions are maintained. So if you had this bright sun and cool temperatures for 6 hours, the panel would deliver 50 x 6 = 900 watt hours, or a little shy of kilowatt-hour. Kilowatt-hours (kWh) is the reading on your electric bill. However, like most advertising, the 50-watt number is not realistic. They assume that the air surrounding the panel is very cold. 25 watts is a better number to use for this size of panel for engineering purposes.
Q:name things someone could use solar panels for or make with solar panels? (use solar energy i mean?)
Solar panels are primarily used to make electricity. What you choose to do with this power is up to you. New solar technology now looks to give the panels more than this one task. For example; - solar panels made into the shape of roof tiles can also be used for roofing. - thin film solar is being developed to add to cars and other mobile devices to provide portable DIY energy
Q:How do solar panels affect the property's carbon footprint?
Solar panels can greatly reduce a property's carbon footprint by generating clean and renewable energy. Since solar panels generate electricity by harnessing the power of the sun, they do not emit any greenhouse gases or pollutants during operation. By reducing reliance on fossil fuels and grid electricity, solar panels help to offset carbon emissions that would have been produced by traditional energy sources, thus positively impacting the property's carbon footprint.
Q:What is the maintenance cost of solar panels?
The maintenance cost of solar panels is generally low. Routine maintenance such as cleaning the panels and checking for any damage or debris is recommended, which can be done by the owner or a professional. Additionally, occasional inspections and repairs may be required, but these costs are minimal compared to the long-term benefits of using solar energy.
Q:Just curious.
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:we are planing to move out of the grid. we need to operate constantly 2 laptops online - does any one can tell us how much solar panels we shall need to make sure of that?
A laptop is about 70 to 00 W, and you have two. You also may need to power a router, and modem. So, about 50W to 250W contineous should cover it. To save power when not in use, you can let the display go blank. This will reduce your solar pannel, and battery size, and cost. You will need batteries, and blocking rectifier to store the energy for use at night, and a 300W to 400W inverter. Checkout the link below for purchasing solar equipment. You can only hope to get about 8 to 9 hours of full output from your solar pannels, and 80% efficiency. The laptops will be on and using about 200W for the 8 hours during the charging period. So your pannels, need to produce that plus 2 times more than this amount, so you can charge the batteries for the evening, at the same time. So for 24 hour operation, you will need 200W x8hrs for the laptops, plus (6 hours*70W)/8=340W avg. Total of ~540W for 8 hours. Assuming you use power saving modes when not in use, you can probably get away with 3x60W -- 520W to 600W pannel. ( Thuja is right, a few cloudy days may knock you offline) Batteries. A common low cost ( $40) automotive battery can hold about 40 Amp/hours at 2V. Under load, you may get 35 Amp hours at 0V, which is about 350Watts for one hour. You need about 80W avg for 6 hours, or ~ 2900Watt Hours. Which means you would need 9 automotive batteries. Deep storage batteries cost more, but are more durable. 6*00W pannels, $460*6 ~ $2800 Inverter $70 Batteries $400 Battery cables, rectifier, lugs, connectors $50 There are probably some other hidden costs. I was rooting for you, but it appears to be pricey. Another thing you can do, is to use the new energy efficient RF florescent bulbs for lighting. The color and brightness are excellent, and a 60W bulb only uses about 3W, and they last a lot longer as well.
Q:I'm a carpenter, and can do electric work. I want to make some money installing Solar Panels. what's the best source?

Q:Solar panels are all divided into these squares, forming a grid like pattern. Is it possible to have a single piece of solar panel?
Solar cells are semiconductor devices like computer chips. Current manufacturing methods create small squares of semiconductors. Companies are researching ways to make thin film solar cells that can be painted on or manufactured in large, possibly flexible sheets, but so far the technology to do that is still more expensive than making little squares and then assembling them into big panels. That may change in the near future, but I can't be sure.
Q:I want to know that if I put solar panels in space if Pluto can recieve energy for iPods and television
Yes. Not practical, but possible. Solar cells actually work best at low temperatures. At a little under W/m^2, it'd take a large solar panel to generate enough power for a TV (several tens to hundreds of Watts are needed). And, no offense meant, what TV programs do you think you'll be watching? You sound kind of stupid....
Q:i need how a solar panel works, if possible make as easy to understand as possible like because of this , this happens and if you could please put a web source you got it from
