I have seen these on some smaller RVs. Being flexible it the best part of them. Your charge controller does not care, or know what kind/brand of solar panels are feeding them. What is more important is how shade tolerant the panels are. If shading one square or circle of the panel shuts off the panel, these are good for a fixed installation, but may not be a good choice for an RV. Solar is good for lights, water pump, RV fridge, furnace, but forget about trying to run AC or any other large or long term 120 volt items. That is why you have a generator. A lot of RVers carry a 2,000 Watt portable generator for watching TV, Movies, coffee making, toast, etc.
