PV Triangles
ULAMEX supplies PV triangle mounts — aluminium support structures that position solar panels at an optimal tilt angle on flat roofs, ground-mounted arrays and carport installations. Available in fixed-angle and adjustable variants, our triangles are manufactured from AL 6060-T6 alloy for maximum strength-to-weight ratio and long-term corrosion resistance. Designed for professional PV installers and solar contractors across Europe.
Solar Panel Tilt Brackets for Flat Roofs and Ground Installations
Tilting solar panels to the correct angle significantly increases energy yield compared to flat mounting. In Central Europe (latitudes 48-54 degrees N), the optimal annual tilt angle ranges from 30 to 35 degrees, while lower angles of 10 to 15 degrees are preferred for flat roof installations where wind uplift and inter-row shading must be minimised.
ULAMEX offers two PV triangle product lines. Our fixed-angle PV triangles are available in pre-set configurations of 15, 20, 25, 30 and 35 degrees — each precisely manufactured to provide a stable, permanent tilt without on-site adjustment. For projects requiring flexibility, our adjustable PV triangles cover a continuous range from 10 to 35 degrees, allowing installers to fine-tune the angle based on latitude, roof orientation and seasonal energy targets.
Both variants are constructed from extruded aluminium AL 6060-T6, delivering high structural rigidity at low weight. The triangles integrate seamlessly with ULAMEX PV mounting profiles (40x40 mm and 45x40 mm cross-sections) and are secured using standard M8/M10 T-bolts and fasteners. For flat roof applications, PV triangles can be combined with ballast mounting systems to create fully non-penetrating installations.
Flat Roof Installations
PV triangles enable tilted module mounting on commercial and industrial flat roofs. Combined with ballast trays, they create non-penetrating systems that preserve roof membrane integrity while maximising energy output.
Ground-Mounted Arrays
For open-field and ground-mounted solar farms, triangles mounted on concrete foundations or ground screws provide stable, long-lasting support structures at the ideal tilt angle.
Carports and Canopies
PV triangles adapt solar modules to carport and canopy structures, allowing dual-purpose installations that generate electricity while providing covered parking.

Frequently Asked Questions
What is the best tilt angle for solar panels in Central Europe?
For fixed installations in Central Europe (latitudes 48-54 degrees N), a tilt angle of 30 to 35 degrees maximises annual energy yield. Lower angles (10-15 degrees) are often chosen for flat roof installations to reduce wind loads and allow tighter row spacing, accepting a small energy loss of approximately 5-8%.
What is the difference between fixed and adjustable PV triangles?
Fixed triangles are manufactured at a specific angle (15, 20, 25, 30 or 35 degrees) and cannot be changed after installation. Adjustable triangles allow angle modification within the range of 10 to 35 degrees, providing flexibility for varying site conditions. Fixed triangles are simpler, faster to install and slightly more cost-effective for large uniform projects.
How do PV triangles handle wind and snow loads?
ULAMEX PV triangles are designed for Eurocode wind and snow load calculations. The aluminium AL 6060-T6 construction provides high strength-to-weight ratio. For site-specific structural verification, wind zone, building height, terrain category and snow load zone must be factored into the calculation by a qualified engineer.
Can PV triangles be used with ballast systems on flat roofs?
Yes. PV triangles combine with ULAMEX ballast trays for non-penetrating flat roof installations. The triangles provide the desired tilt angle while ballast holders secure the system against wind uplift without roof penetrations.
What row spacing is needed to avoid inter-row shading?
Row spacing depends on tilt angle, module height and local latitude. As a general guideline, a spacing of 1.5 to 2.5 times the module height (measured vertically from the rear edge) prevents significant shading at the winter solstice. Steeper tilt angles require greater row spacing.
Are PV triangles compatible with large 400W+ modules?
Yes. Both fixed and adjustable triangles accommodate modules up to 2200 mm in length, in portrait and landscape orientation. The AL 6060-T6 construction ensures sufficient load-bearing capacity for current-generation large-format modules.
Does ULAMEX supply PV triangles wholesale?
Yes. ULAMEX is a B2B wholesaler supplying PV installers and distributors across Europe. We offer pallet delivery, volume-based pricing and complete PV mounting system packages including profiles, clamps and fasteners.
