Posts & ground screws

A good grounding, a stable and long-term resilient foundation are the solid basis of a PV investment. We therefore pay particular attention to this area of our mounting solutions. Depending on the ground conditions, ground corrosiveness and static requirements, MSY Systems offers different shapes, dimensions and materials for the foundation of your PV system.
