Solar panel mounting & brackets
How your panel attaches decides whether it survives highway speeds and storms. Match the mount to your surface — roof, RV, or ground — and to whether you want to tilt toward the sun.
Mounts worth knowing first
Common picks by mounting situation. Always match hardware to your panel’s size and your surface.

Adjustable tilt mount
ABS corner mounts
How to choose
The surface and whether you want to tilt are the two questions that decide which bracket you need.
Surface & location
A flat RV roof, a pitched house roof, and a ground mount all call for different hardware. Start from where the panel will live.
- RV / van roofs: low-profile brackets
- Ground / pole: adjustable stands
- Pitched roofs: rails and feet
Fixed vs tilt
Fixed mounts are simplest and lowest-profile; tilt mounts let you angle panels toward the sun for more output, which helps most in winter or at high latitudes.
- Fixed: simple, aerodynamic, set-and-forget
- Tilt: more output, more wind exposure
- Tilt pays off most in winter sun
Drill vs adhesive
Drilled brackets are the most secure but put holes in your roof; strong adhesive (VHB) and no-drill corner mounts avoid penetrations on thin or rented roofs.
- Drilled: strongest hold, needs sealing
- Adhesive/VHB: no holes, surface prep matters
- No-drill is popular for vans and RVs
Material, load & sealing
Favor corrosion-free aluminum hardware, make sure it can handle wind load at speed, and seal every penetration to keep water out.
- Corrosion-free aluminum lasts outdoors
- Consider wind load at highway speeds
- Seal all drilled holes thoroughly
Mounts by type
Z-brackets
The default low-profile fixed mount — four aluminum brackets bolt a rigid panel flat to a roof.
Tilt mounts
Adjustable arms that angle a panel toward the sun for more output, useful for seasonal tuning.
Corner / no-drill mounts
ABS corner brackets that bond with strong adhesive, avoiding roof penetrations on RVs and vans.
Ground & pole mounts
Free-standing stands and pole mounts for cabins and off-grid sites where roof mounting isn’t ideal.

Mounting FAQ
Not necessarily. Drilled brackets give the strongest hold but need careful sealing. Many RV and van owners use no-drill corner mounts with strong VHB adhesive to avoid penetrating the roof.
It can be. Tilting panels toward the sun increases output, with the biggest gains in winter and at higher latitudes. The trade-off is more wind exposure and a bit more setup, so flat mounting is fine for many.
Match brackets to your panel’s frame and weight, and to the mounting surface. Z-brackets suit most standard rigid panels; larger panels may need rails or heavier-duty hardware.
A typical rigid panel uses a set of four brackets, one near each corner. Larger or heavier panels, or installs facing high wind, may need additional support.
Seal every drilled penetration with a suitable sealant and follow the bracket maker’s instructions. No-drill adhesive mounts avoid the issue entirely by not penetrating the roof.
