is this really a Polycrystalline solar panel, why does it say in the description that the solar cell is monocrystalline?

The one I received is Polycrystalline. Very good panel, used it for Field Day for my HAM radios.

The solar panel is on top. The only one I found with the panel integeral to the unit.I have it installed on the West wall about 10 feet up. This is a two-story brick home with a big tree in front, overlapping this aide.I'd estimate that it only see's direct sun for ~3 hrs per sunny day.It worked immediatly. I've been showing my neoghbor, and he bought two for the West wall of his house.NO complaints.... Well made...You'll be very plesased !

Hi Raymond. The solar panel details are such: 2.5Wp, 7.8V polycrystalline solar module. I would suggest staying at our below these levels.

polycrystaline. In fact, if a 10 w panel is made by poly and mono or amorphous, their output is same(10w), but size is different. The panel made by poly or mono, their size almost the same. And since of lower effiency, the size of amorphous almost doubled. Since the tech of poly was increased, the difference between poly and mono is become less and less, now 90% panel in market is made by poly.

Hey folks, to be clear, "retracer" is actually wrong. The panels are actually built OUT OF COUNTRY. I just confirmed this by speaking directly with someone at Grape Solar in Eugene, OR. With that said, these folks are extremely helpful and have been more than willing to help in answering any questions I've had related to their products and even how I can connect their products into an existing solar project that I have NOT containing their products.

You are correct, only one solar panel. Not to mention, they are very difficult to assemble due to size and none of these items work very well as they have to be in direct sun light, not through a window. Even outside, the panel has to face the sun directly or you get nothing. Don't waste your money

The panels come with a fairly rugged aluminum frame around the panel edges but nothing more. The frame has a flange on the inside all the way around the back side, with perhaps 3/8 of an inch between the back of the panel and the flange. There are holes (four of them if I remember) drilled in the flange that allow the panel to be attached to something else. It is more than adequate for sturdy mounting of the panels. This arrangement is very typical of other solar panels I have seen, as well.

Seems like Mamdogtag has no idea one comment he says it's Mono and the other he says Crystalline. To me they look like they are Polycrystalline Silicon Solar Cells

the only thing that I can think of is that it didnt get enough sunlight ....mine work fine have had them for a couple months now just make sure it has direct sunlight for 6-7 hrs a day and stays lite most of the night ... if not then it is probably defective solar panel

The housing and flashing on this unit are commercial grade aluminum and the gray paint is a powder coated paint. The solar panel is framed in commercial grade aluminum, too, and the adjustable supports that allow you to position the panel are also heavy aluminum. More info on the components is available on the manufacturers site solaratticfan dot com.

Jeff, the dimension is 1010x680x35 mm (39.7x26.7x1.4 inches). You can refer the details from the listing of the single 100W polycrystalline solar panels. Thanks.

The panel does not output 5W like the specs and other reviewers suggest. The integrated *battery pack* outputs 5W, but the panel itself seems to only output in the range of 1W to 1.5W.From the specs directly from the manufacturer, the battery is 2200mah, and it takes the panel 10 hours to charge it. If you work the math out, that means it charges 220mah per hour, which would be 220ma of current @ around 5V (maybe slightly higher?), 5v * .22a = 1.1WJust because the unit has the capability to output at 5W, doesn't mean it can collect power from the sun comparable to a 5W panel.

This is a "battery" panel. To work together with my local energy provider, you'll need to connect "grid-tie" panels using quality grid-tie inverters..

Hi Jennifer, the panel that came with the kit is a UL SOLAR panel...it is 30 watts 12 volt polycrystalline with the ac plug wire already attched. I tested the unit. Ran down to 20% and attached panel. Recharged in 7 hours.

The solar panel is on the pump mechanism. The box is small, it doesn't look like it was made to come apart.

Agree with Todd & Kate. It is what it is, a "solar" panel depending totally on UV rays to generate a charge. The panel will not generate a charge at night nor on dark overcast days.

I do not think so - but it appears to be very well made - My question for you would be: "Is the solar panel sold by Mighty Mule manufactured by Mighty Mule?"I would bet not
