We are faced with a flat domestic roof with little space available to build a photovoltaic system. Our customer Antrac turned to us to identify the best solution which in this case was represented by the 11 ° Sail-shaped system which with three rows of solar panels connected to each other without the need to create space between the rows, was able to install a 3.3 kWp clean energy plant in Tarragona in Spain.
Furthermore, Sun Ballast ballasts do not need holes in the cover to be fixed and this avoids problems of water infiltration.
