Our Optima system for trapezoidal wave trays is fixed directly into the building structure for better stability of the photovoltaic system, even in extreme wind conditions. Its design allows a secure fixing in place of the jumper to avoid any drilling of the tray. The Magnelis® coating offers an anti-corrosion guarantee. We have developed our Optima system into a range of solutions to meet the specific requirements of different types of roofs: Asbestos cement, Sandwich Panels, Tiles and Kalzip®.
