Flexible Solar: Junk vs. High Quality?

I've heard some bad things about flexible panels - one RV guy I know said he had 3 of them that almost caught his van on fire.  He trashed them.  However, those were "no name" brand panels.

Our hosts now sell a 100W flexible panel: https://www.solar-electric.com/sunpower-flexible-solar-panel-100-watt-monocrystalline.html

It's made by SunPower - a name I trust as I have 5KW of their (non flexible) panels on my house.

Any experiences pro or con with the SunPower SPR-E-Flex line?

    There are a few different types of flexible panels. These I would call semi flexible. They are in my opinion better than the Unisolar thinfilm type panels that came in a roll with adhesive on the back. Flexible panels aren't known to last as long as rigid panels. I think your best bet would be to mount these where they won't get any physical contact or other type of abuse and be done.. Keep in mind there wont be any airflow under the cells so they might run warmer than conventional panels mounted with an air space under them.
