These flexible, completely waterproof solar panels are designed for marine use. They provide a sustainable, reliable and efficient source of energy on board. The Sunpower cells used are among the most efficient on the market with an efficiency of 23.1 - 23.5% (30% higher than conventional cells). The cells are wrapped in a composite (ethylene tetrafluoroethylene ETFE) which ensures that the flexible panels holds very well over time. This manufacturing technique also allows the panels to have impressive bending characteristics, 30 cm by 1m. Their low weight combined with their excellent strength and flexibility as well as thinness allows them to be used on flexible, rigid biminis or for mobile applications, such as deck or boom positioning while at anchor. perfect seal at the cable outlet. These flexible solar panels have an excellent level of robustness. They are designed to resist occasional trampling.
