I was a little hesitant to order from these guys but was pleasantly surprised! I needed something less than 35x35in and these fit the bill perfectly. Not only that, but they are using Sunpower cells which when placed side by side with my other panels, produced substantially more power in the same conditions. In the photos you can see a single panel going to my little power station producing 106w in good 95 deg conditions. It actually started at 116w before it got hot. The other photo is the two panels in series to my Delta Mini going for 210w. In cooler weather I have no doubt these will reach the 230w.One concern is that the MC4 connections aren't very long, and when I looked inside the junction box to possibly add longer ones, it is filled with the white sealant. I'm not sure if I'll attempt to remove it, or splice in a longer cable from the existing one, but I do need these cables to be longer (I don't want to use extensions). My other concern is the top coating of the panels, it feels a little soft and not so rugged to the touch, so I hope it holds up. If it is ETFE like the description says, then it should last a very long time.
