I have been researching flexible solar panels for my van for a while and am ready to take the plunge. I know all the cons with using flex vs solid panels, but flexible is the only thing that will work in my situation.
I came across a site, Boss Watt, and they have SunPower 100W panels on sale for $195 free shipping. That is about $35-40 less than anywhere else I have seen. So if you are in the market, it might be worth checking out.
I may go with the Boss Watt brand 120W panel. They use SunPower cells and seem to have a quality build. It ends up being less $ per watt.
