Since its introduction, the SUNBEAMsystem Tough series has been the absolute winner in multiple real- life tests. All Tough models are fitted with SunpowerTM Maxeon cells with an efficiency of 22.5% or higher. The anti-slip profile is not only practical for deck mounting; it also catches more light in low sun angles. In addition, the dirt-repellent properties also improve daily production by helping to keep the panels clean. It also provides a safe and walkable surface, without any cables to trip on.
