The Renogy Flexible Solar Panel uses advanced technology backed by contact monocrystalline cells that have been laminated into a flexible plastic sheet. The result is a solar panel that is far more durable than traditional glass and aluminum models, with twice the efficiency (approx. 20%) of flexible thin film solar panels.
