Are there solar panels for portable or rough service or vandal prone areas?
Yes, there are unbreakable panels, which are essentially a sheet of stainless steel with the solar material bonded to it, which have no glass front, and will tolerate dropping, impact, and vandalism. And there are flexible and folding solar panels, some military grade, up to 55 watts for camping, backpacking, scientific investigations, etc., where permanent installation or daily use is not intended. Then there are UniSolar panels, which are similar to the stainless units mentioned above, but have an aluminum frame like a standard panel, and are available up to 64 watts. Unfortunately, the UniSolar panels are sometimes built in sporadic batches, and not always available.
