A classic way to hold solar panels
These Z-shaped mounting brackets from Wattstunde hold a solar panel by its frame on a base such as a shed roof, a rail, a trailer bed or a metal structure. The Z profile grips the edge of the frame on one side while the opposite tab is screwed to the support, so the panel itself never has to be drilled.
Who uses them and where
A homeowner can use them to put a module on a garden shed, a carport or a motorhome roof. A tradesperson or installer might choose them for small off-grid generators, technical shelters or test benches where module layouts are changed often.
How many do you need?
The number of brackets depends on the weight and size of the panel and on the recommendations of its manufacturer. Read the module’s instructions before deciding how to spread the fixing points.
Design and materials
The body is made entirely of aluminum, a light metal that stays easy to carry and to handle at height. The fixing screws supplied are stainless steel, a sensible choice for parts left outdoors. Each bracket measures 10 x 5 x 2.7 cm.
Because the format is modest, the brackets suit installations where space around the frame is tight, for instance between two rails or close to a roof edge. Choose a support that can take the screws without splitting, and plan the layout on paper before you mark any hole.
Fitting step by step
- Clean and inspect the support surface: it should be flat, sound and strong enough.
- Place the panel and mark where each bracket will sit along the frame.
- Fasten the brackets to the support first, then slide the frame edge under the Z section.
- Tighten gradually, alternating between points, so the frame is not distorted.
If the support is a roof or a timber structure, have a professional check its strength and weatherproofing. Wiring the panel is a job for a qualified installer.

Safety advice
Wear gloves and eye protection, particularly when drilling. Never stand on a roof without suitable fall protection, and avoid working in strong wind or on a wet surface. Check that the screws chosen for the support suit its material: wood, metal or anything else.
Care and storage
Check the tightness of the screws from time to time, especially after big temperature swings or a storm. Wipe the brackets with a damp cloth and a little mild soap. When not in use, keep them in a dry place together with their screws so that no part gets lost.
