100 Watt Renogy bendable solar panels

At four pounds it is four times lighter and smaller than the 75 watt Siemens panels I bought over a decade ago. Not sure if they will hold up as well and I'd be leery to walk on it. But, I'm impressed with it so far. Gave a nice bump up in energy collection and easily movable compared to the rigid panels.:…See More
