BougeRV Yuma 200W CIGS Thin-Film Flexible Solar Panel, The Most Flexible Solar Panel with Tape for Easy Installation

This fit perfectly on the roof of my 25 ft airstream and keeps the batteries well charged.

For those who don't want to drill holes in the roof of their RV, this is a very good option. There are four adhesive strips on the back and the backing strips come off easily without mess even in hot weather. The adhesive is some sort of roofing cement like Henry's or something. Once the panel is laid down, it is not coming up. The panels are very flexible and durable. You can walk on them with no problem. I installed four 200W panels and at high noon. I am getting a total of 670W. Decent. My only real gripe with these are the price. They are spendy. However, Bouge often has deals on these and if you are patient, you might be able to pick these up in the low four hundred range. For me, the BougeRV Yuma 200W CIGS Thin-Film Flexible Solar Panel were a solid winner.

When I finally saw someone selling CIGS panels I went all in. Two 200w panels mounted to the front of my camper for optimal panel angle. On a partly cloudy November day in Texas, still producing over 400 watts. The panels themselves, if you do a little bit of maths with the specs, are actually 285 watt panels in a perfect world. I guess BougeRV oversized them considering most people would mount them horizontal, to offset the 20-25% loss of horizontal mounting and their customers could still get the 200w advertised output. Genius! Even better for me with an optimal mounting angle! I paid for 400w, and got 500w!

Cigs are the only flexibke solar panel worth getting that lasts past a few years

Installed on top of my iKamper rooftop tent, the adhesive is rock solid and made installation super easy. the cabling is quality and well done. I've been very happy with the output - works great to keep my batteries charged and ready to go at all times.
