Rooftop solar is the default for homes — but for larger loads or unsuitable roofs, ground-mounted systems are often the better fit.
Key differences
- Rooftop — no extra land needed, but limited by roof area and shading.
- Ground-mounted — flexible sizing and orientation, needs available land.
- Ground systems are easier to expand later.

Bifacial panels perform especially well on ground-mounts — see panel types compared for details.
