extremely durable and resistant
Since its introduction, the SUNBEAMsystem Tough series has been the absolute winner in multiple real-life tests. Due to the wide range of different models, the Tough series provides a universal solution for numerous applications. The Tough surface is the preferred choice for the yachting industry, but also for more industrial off-grid purposes. All Tough models are fitted with Sunpower™ Maxeon cells with an efficiency of 22.5% or higher.
The surface of the Tough series is extremely durable and resistant to strong and long UV exposure. It transmits more light than standard materials, contributing to a higher daily production. The ribbed profile provides a steady grip when walking on the panel, but also catches more light in low sun angles. In addition, Tough models 55W, 78W and 111W, both flush or junction box, are equipped with SUNBEAMsystems protected Shadow Optimized technology, improving output in partially shaded conditions.
The anti-slip profile provides a safe and walkable surface, without any cables to trip on. The mere thickness of only 3mm enables a perfect installation on a yacht deck. For installation, we recommend double-sided tape or a soft flexible glue like the white Sikaflex 291i or 591.
