Flexible Panels - Which would you choose and why: Sunpower, Renogy, Merlin

[Bvillebob]

I've had 4 of the HQST flexibles on my van for several years now, still working great, I've been very happy with them. With a 60 hp engine the low profile / flat on the roof is very important to me for wind resistance reasons, I need all the help I can get.
