Out of all 100 W flexible solar panels,
this is one of the most popular. The Renogy panel is about 70% lighter than conventional panels of the same size — a mere 4.2 lbs. It’s about as thick as a coin, and you can bend it almost to the point where the opposite ends of the panel meet. Renogy solar panels have great ratings, and this model comes with a 3-year material and workmanship warranty.
