Mounting & placement
Solar panel brackets: types and how to choose
Brackets are what actually hold a panel in place, so the right choice depends as much on the surface as the panel. Pick the wrong one and even a good panel can be insecure.This guide runs through the common bracket types and how to match them to your spot. For the full picture, see the mounting systems hub.

The main bracket types
Most plug-in mounting uses a handful of bracket families, often in combination. The right one matches both the panel frame and the surface you're fixing to.
| Bracket | What it does | Typical use |
|---|---|---|
| End/mid clamps | Grip the panel's aluminium frame | Fixing a panel onto rails or a frame |
| Mounting rails | A base run for clamps to attach to | Walls, roofs and frames |
| Angled / tilt frame | Sets a fixed tilt angle | Flat roofs, gardens, vertical walls |
| A-frame | Free-standing angled support | Ground and flat-roof, often ballasted |
| Railing clamps | Clamp to a balustrade or rail | Balconies and fences, no drilling |
Matching the bracket to the surface
A bracket is only as good as what it fixes to. On a wall, the fixing must reach sound masonry or structure, not just render or cladding. On a fence or railing, a clamp avoids drilling but relies on the rail being strong. On a flat roof or the ground, an angled or A-frame is often ballasted rather than bolted. The tilt the bracket sets also affects output — see direction and angle.
Getting the fixing right
Whatever the bracket, the load has to be carried safely. An angled panel catches a lot of wind, so brackets, clamps and fixings all need to be rated for the job and installed as the manufacturer intends.

Frequently asked questions
- What brackets do I need for a solar panel?
- It depends on the surface: clamps and rails for walls and frames, angled or A-frames to set a tilt on flat roofs and ground, and railing clamps for balconies and fences. Match the bracket to both the panel frame and a structural fixing point.
- Can you mount a solar panel without drilling?
- Sometimes. Railing clamps grip a balustrade or fence rail without drilling, and ballasted frames use weight instead of bolts on flat roofs and the ground. Both still need to be rated and installed for the panel's weight and wind load.
