RVs also use solar panels as one of the main sources of energy. But I have learned to avoid those flexible solar panels (that Sonos is seemingly using as well) because they do not last a long time. They break usually long before 10 years are over. Also it should be noted that solar panels lose efficiency the hotter they get. Solar panels that are directly glued on the surface have no ventilation and thus get hot, lose efficiency and the heat also does not help to make them last longer. Of course, properly mounted panels you find on most RVs cause a bit more drag. There are military grade flexible solar panels available that don’t have most of the mentioned side effects but they are like 5x more expensive.
