Moisolar Nordic Flat EAST-WEST Portrait 15 is a high-quality and durable solar panel mounting system designed for flat roofs. Engineered to ensure long-lasting performance, safety, and easy installation, it provides a secure foundation for solar panels while protecting the roof structure. Optimized aerodynamics reduce wind loads, and site-specific calculations guarantee the best possible solution for all roof types.
The system support solar panels up to 1800 mm in length. Panels longer than 1800 mm require a custom-designed solution.
EXCEPTIONAL DURABILITY & LONGEVITY
In the East West Portrait mount, the rail lines run through the long side of the panels, achieving maximum snow load resistance.
LOWER WEIGHTS
In favorable locations, weight reductions of up to 90% compared to south-facing mounts.
MORE POWER
Up to 50% more solar panels can be installed on the same surface area.
Pre-Assembled for Quick Installation
Our mounting frames are delivered pre-assembled in the South-facing configuration. To switch to an East-West orientation, simply disassemble the frame by removing the bolts, reposition the triangle shoulders to the designated East-West slots, and reattach the bolts to the predefined mounting points.
Each frame is designed with a fixed 15° tilt angle and includes standard mounting positions for solar panel brackets, ensuring quick and secure installation. The frame base is fitted with a durable 8–15 mm butyl or rubber mat. This protects the roof surface and supports efficient water drainage.
Mounting Options for flat roofs
Nordic Flat EAST-WEST Portrait 15 can be mounted on flat roofs using different methods, chosen based on site-specific requirements. Wind and weight calculations, along with the characteristics of the roofing material, determine the optimal solution. Often, the most reliable and long-lasting option is a combination of bitumen welding and ballast weights, ensuring both durability and safety.
Method 1 - Bitumen Welding for Flat Roofs
This method is ideal for installations where reducing ballast weight is necessary or more load sharing area against roof is needed. Excellent solution for locations with high wind loads, where ballast amount will increase too much.
Materials:
- FP01 – Base plate steel
- FS02 – Bolt-nut set
- FM01 – 700 × 700 mm bitumen patch
Method 2 - Ballast Weights
The windshield tray accommodates ballast plates up to 50 mm thick, with a recommended side length of 200 mm (max 300 mm). Bitumen welding and ballast weights can also be used together for enhanced stability. The ratio and amount of ballast and bitumen welding are determined case-by-case based on project requirements.
The triangular frame can hold 4 pieces of 300 × 300 × 50 mm ballast weights for additional support.
Method 3 – Cold Adhesion with Rubber Feet
- Roof-friendly solution when used with ballast weights
- Allows free water drainage under the mounting system
- Reduces slippage risk while the flexible structure absorbs forces from wind and thermal expansion
- Can also be used without adhesive as a weight holder to increase support surface area on the roof
Materials:
RS23 – Rubber feet & Special adhesive
Method 4 – Cold Adhesion with Adhesive Steel Plate
- Strong roof attachment without damaging the waterproof membrane
- Adhesion applied after installation, can be used as an extension kit replacement or inside the triangular frame
- No pre-measuring required for installation
- No hot work permits needed
- Can be used together with ballast weights for added stability
- Allows system elevation up to 65 mm from the roof, positioning the panel’s lower edge 105 mm above the roof surface
Materials:
- Adhesive steel plate & special adhesive
- Bolt or self-drilling EJOT screw
Adjustable Leg - Solution for Uneven Roof Surfaces
Flat roofs often have slopes, drains, edge areas, or other local height variations that can pose significant challenges for system installation. The adjustable leg ensures that the base rail is properly supported in areas where it would otherwise be suspended, reducing the risk of structural strain on the mounting system and preventing potential damage to the roof.
✔ Stabilizes uneven areas where the base rail lacks direct support
✔ Compatible with the universal wedge piece for precise vertical alignment in
✔ Can be used selectively to level and elevate the system as needed
