Most common for balconies. Rails attach to balcony railing or floor.

Best for: Most balcony types, adjustable angle

Wall Mounting

Panels mount directly to exterior wall above or beside balcony.

Best for: Limited floor space, south-facing walls

Ground Mount (Portable)

Portable stands that sit on balcony floor, adjustable angle.

Best for: Renters, flexible positioning

Choosing the Right Mount

Consider your balcony type, space constraints, sun exposure, and whether you need to move panels. Rail mounting is most versatile for permanent installations.

💡 Safety First

Ensure mounting hardware is rated for wind loads in your area. See our wind load guide and safety guide for installation best practices.
