A commercial solar system of 100.33 kWp built by Rotem Energy on the concrete roofs of a roasting plant in the city of Sakhnin. The system was spread across several buildings on the plant's grounds to make the most of the available roof area, using mounting hardware designed specifically for concrete roofs and a layout planned to prevent shading between the panel rows. The system produces electricity throughout the day and turns the plant's unused roof space into steady income.
