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.

Q:Advice on Solar Panel....................................?
The thing is having a solar panel is a great advantage when you want to have save a money but it doesn't necessarily means that it will cover up your expectations. Expand your knowledge and learn from a renowned solar company about the Best Solar Panels. Visit our site and contact us today!
Q:are solar panels worth buying?
Of okorder.com
Q:where to find used solar panels?
That's not a good idea. Solar panels wear out, and you probably won't know how worn out they are until you buy them and install them. Which is a little bit too late for most refunds. Your best bet if you're dead set on being foolish, is probably some place like craigslist.
Q:How much maintenance do solar panels require?
New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link
Q:How did Obamas funded solar panel plan flop and bunkrupt..where did those billions of dollars go?
Yes, solar panels could change the world if they were especially cheap--but they're not and may not be cheap for many years, if ever. Lots of new technology could change the world but most of it doesn't. The government doesn't have a very good track record of picking winners in the new technology markets; that's something we should probably leave to the venture capitalists to do--with their own money. The money the government spent on solar panels is gone. Racked up as debt that we'll leave to our children and grandchildren to pay off.
Q:harbor freight solar panels ?
Unless things have changed in the past few years, their panels are amorphous silicon, and sharply decline in output after 6 to 2 months. The panels have no STC (standard test condition) rating, so the 5-watt panel is really more like 5 watts. And the warranty is very short - 90 days, compared to the 25-year performance warranty of any serious crystalline silicon panel. But if you have a fun little project that does not have to last, Harbor Freight is a convenient source.
Q:solar panel efficiency in space?
I'm not sure on the exact numbers of solar panel efficiency, however i do know that at the radius of the Earth we should be receiving about 000W of power per square meter. This value is lessened by the atmosphere to a value closer to 600W per square meter on the Earth's surface. (on a really hot day) That's a 40% drop in power due to the atmosphere. I'm assuming that the solar panels being in space don't affect it's efficiency (as in mechanically). So its power generation should increase by about 40% when in space compared with a ground based panel of the same design. Hope this helps, Sorry it's kinda sketchy info...
Q:question about Solar Panels?
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
Q:Solar panel questions...?
. Do they scratch easily? No How do I remove snow from them without scratching them? Just wipe the snow off 2. What does the upkeep of many solar panels consist of? Clean them with tap water and paper towels once a month. 3. Are all solar panels made from the same material, regardless of size? Basically the same.
Q:Questions about charging batteries via solar panel...?
The important part of the long answer is the charge controller - those batteries cost way too much to cook them out. And the controller maker will specify how much voltage your panels need to supply (more than 24 certainly) to provide a charge for several hours a day so you aren't wasting money on something that actually does very little. I also hope you have a very secure location to store this rig at work because while a bike with a tow trailer is easy to disguise and awkward to move, as soon as you put a solar panel on it, it becomes a very obvious theft target and maybe a vandalism target. And since you want to charge at work, it has to be outside. And since for effective use the panel has to mostly face the sun but you don't want to drag it broadside through the air while riding, you will have to either work out a pivoting mount or angle the whole trailer to the general position of the sun when parked and have the panel flat on top. I personally would probably redesign so that at work the trailer pulled up along side the bike and was chained/locked to it to make a really awkward mass that had the panel bolted through the lid with blind bolts.
