A commercial solar system of 149 kWp built by Rotem Energy on the roof of a shopping center in the city of Elad. The roof of the building is made of insulated sandwich panel covered with bituminous waterproofing membranes, so it called for a dedicated mounting solution that works with the waterproofing layer and keeps it intact over time. The panel layout was planned around the shape of the roof and the equipment already installed on it, so that the shopping center uses its full roof area to generate electricity.
