I work for a solar panel manufacturer. I am a manufacturing engineer. My department actually cuts the wafers that are made into cells. We make rigid panels for residential and commercial use. I have an old panel of ours from the 90's that is for marine use. We no longer make these, unfortunatly. Anyway, I will let you all know that thin film panels are the holy grail of solar. No one has a flexible/rollable panel that will compete with a rigid over time. The way they are currently made, by depositing silicon vapor on a flexible film, panels will not last more than 2 years. It is very difficult to maintain the integrity of a very brittle material while is is allowed to flex. Don't waste your money on non-rigid panels. I have seen some very lightweight panels that have the cells mounted to corrugated plastic. These are for use at dock or at anchor and cannot withstand high winds. I don't know who makes them, but they are out there.
