The Ballast Mounting System is a flat roof solar installation system, which is usually used for roofs with minimum slope or no slope. The system is often used in large commercial projects, and the owners want to minimize roof penetration when installing solar panels. In a ballast system, concrete blocks are placed to reduce the weight of the solar array and prevent the panel from being affected by weather factors such as wind or snow. Flat roofs are very suitable for solar installation because they are easy for system assembly and direct access.
