MMS (Module Mounting Structure)

The module mounting structure is the steel or aluminium framework that fixes panels to the roof or ground at the design tilt. Structure quality decides whether a plant survives 25 years of wind and monsoon.

Indian practice uses hot-dip galvanised steel (IS 4759, 80+ micron coating) or marine-grade aluminium, designed for site wind speed per IS 875. Elevated RCC-roof structures preserve terrace use and enable bifacial gain.
