Rooftop vs Ground-Mount: The Structural Economics

The choice between rooftop and ground-mount solar is partly about generation and partly about the structure and installation. Each has a different cost and effort profile.
Rooftop
Rooftop uses existing roof area, avoiding land and heavy foundations, but the design must respect the roof type, uplift on the building and access constraints.
Ground-mount
Ground-mount allows optimal tilt and spacing for higher per-kW yield, but adds land, foundations and civil work. At scale it is often the more economical route.
