Stay away from the cheap junkers made from PET plastic. The Renogy panels--and others--are made from ETFE.

I learned that lesson in June when I bought an ALLPOWERS 140 Watt Folding Solar Panel Kit via Walmart Marketplace. It had all 5 stars as far as Walmart reviews so I took a chance. It seemed well made and a convenient package (it is foldable/portable). I plugged it in on a clear, cool Summer day and pointed it at a good angle to the sun and the best it would do is 70 watts. It went straight back to the shipper. I don't expect a low priced portable panel to get anywhere near its rated power output but I was hoping for at least 75% in those conditions. I immediately plugged in my 100 watt full frame panel and was getting almost 90 watts.

When installing those flexible solar panels on your roof, a couple of things to consider: About leaving a small air gap between the roof and the panel it can be a good idea for ventilation and preventing heat buildup. However, it's not always mandatory, and it might depend on your specific setup and how well the panels are sealed
