The ULAMEX adjustable PV triangle is a continuously variable solar panel tilt bracket that allows installers to set the module inclination to any angle between 15 and 30 degrees on site — without pre-ordering a specific fixed-angle variant. Constructed from EN AW-6060 T6 aluminum with a precision stainless steel H17 hinge mechanism, this adjustable triangle delivers the flexibility demanded by projects where optimal tilt varies between array sections, where future angle adjustment may be desired, or where a single stock item must serve multiple projects at different latitudes. The hinge locks securely at the chosen angle via stainless steel bolts, creating a rigid structure that performs identically to a fixed triangle under wind, snow and dead loads once tightened. Compatible with all ULAMEX PV profiles, clamps and ballast systems.

How It Works — On-Site Angle Adjustment
The adjustable PV triangle arrives as a two-piece assembly connected by the stainless steel H17 hinge. On site, the installer loosens the hinge bolts, pivots the inclined arm to the desired angle (verified with an inclinometer or digital angle gauge), and retightens the bolts to lock the position. The hinge mechanism provides continuous adjustment — there are no discrete detent positions, so any angle between 15° and 30° can be selected with precision. Once locked, the triangle behaves as a rigid, fixed-angle structure for the lifetime of the installation. Mount the triangle base to ballast handles on flat roofs or to concrete foundations on ground mounts. Attach PV aluminum profiles to the inclined arm, then secure modules with middle and end clamps. The stainless steel hinge ensures corrosion-free operation even in outdoor environments with high humidity or coastal salt exposure.
Compatible Components
The adjustable PV triangle integrates with the complete ULAMEX mounting system. For flat roofs, pair with aluminum or galvanized ballast handles to create non-penetrating installations. Attach PV aluminum profiles (40×40, 45×40 or 80×40 mm) to the inclined triangle arm and secure modules with middle and end clamps. All connections use standard M8/M10 T-bolts and sliding nuts. For projects where a fixed angle suffices and cost optimization is paramount, see the fixed-angle PV triangles (15° and 30°).
Application Scenarios
Multi-section flat roof arrays: On large commercial flat roofs where different sections face different directions or experience different shading patterns from parapets, HVAC equipment or adjacent buildings, the adjustable triangle allows each section to be optimized independently — one area at 20°, another at 25°, a third at 15° — all using the same hardware SKU.
Projects across multiple latitudes: Solar installers and distributors serving clients across different European countries can stock a single adjustable triangle SKU instead of multiple fixed-angle variants. A project in southern Germany (latitude 48° N) might use 30°, while a project in Denmark (latitude 56° N) might use 25° — the same adjustable triangle covers both.
Ground-mounted arrays with future adjustment: For research installations, pilot projects or arrays where seasonal tilt optimization is desired, the adjustable hinge allows the angle to be changed post-installation. Loosening the hinge bolts, repositioning the arm, and retightening takes minutes per triangle — enabling twice-yearly adjustment (steeper in winter, flatter in summer) for installations that warrant the maintenance effort.
Retrofit and renovation projects: When adding solar panels to existing flat roof structures where the optimal angle is uncertain until the site survey is complete, the adjustable triangle lets the installer make the final angle decision on-site after assessing shading, orientation and structural conditions firsthand.
Selection Guide — Adjustable vs. Fixed PV Triangles
Choose the adjustable PV triangle when your project requires angle flexibility — either between sections, between projects, or over time. The continuous 15°–30° range covers the practical tilt spectrum for flat roof and ground-mount installations across Central and Northern Europe. Choose fixed-angle PV triangles (15° or 30°) when every module row uses the same angle, the angle is known in advance, and maximum simplicity and cost efficiency are priorities. For large uniform arrays, fixed triangles install slightly faster because no angle setting step is needed. For projects with mixed angles, the adjustable triangle eliminates the need to manage multiple SKUs.

Frequently Asked Questions
What is the adjustable range of the ULAMEX adjustable PV triangle?
The adjustable PV triangle covers a continuous range from 15 to 30 degrees. Any angle within this range can be set precisely on site using an inclinometer or digital angle gauge. Once locked with the stainless steel hinge bolts, the triangle becomes a rigid, fixed structure.
What material is the hinge made from and why?
The hinge is manufactured from stainless steel H17 (equivalent to AISI 430), a ferritic stainless steel chosen for its corrosion resistance, mechanical strength and compatibility with the aluminum triangle body. Stainless steel ensures the hinge mechanism remains functional and corrosion-free for the full 25+ year service life of the PV installation, even in humid or coastal environments.
Can the angle be changed after modules are installed?
Yes, but it requires removing or loosening the modules and profiles first to relieve the load on the hinge. Once the hinge bolts are loosened, the arm can be repositioned to a new angle and retightened. This process takes approximately 5–10 minutes per triangle and is feasible for seasonal tilt adjustments on installations where maximizing yield justifies the maintenance effort.
Is the adjustable triangle as structurally strong as a fixed triangle once locked?
Yes. When the stainless steel hinge bolts are fully tightened, the adjustable triangle forms a rigid assembly with structural performance equivalent to a fixed-angle triangle of the same material and cross-section. The hinge design ensures that all wind, snow and dead loads are transferred through the locked joint without play or deflection.
