Ground-Mount vs Rooftop Solar Structures: Which to Choose
The choice depends on available land versus roof area, scale, foundation options and installation constraints.
| Specification | Ground-Mount | Rooftop |
|---|---|---|
| Location | Open land / fields | Building roof (RCC or metal) |
| Foundation | Pile / pedestal / screw | Ballasted or anchored to roof |
| Typical scale | Medium to utility scale | Small to medium (roof-limited) |
| Tilt | Optimised fixed tilt | Roof-following or low tilt |
| Wind design | Full IS 875 exposure | Roof height + uplift on building |
Frequently asked questions
- Which gives more generation?
- Ground-mount usually allows optimum tilt and spacing, so per-kW yield is often higher; rooftop wins where land is unavailable and uses otherwise idle roof area.
