Choose the best flat roof solar mount: Fixed, Hybrid or Ballasted
Choosing the right solar mounting system for flat roofs is key, especially for lightweight or complex roofs, or areas with heavy snow or strong winds. Each roof has unique structure, load limits, and environmental needs.
Which solar panel mounting system fits your flat roof best?

Ballasted systems
Ideal for flat roofs, ballasted systems use weight to secure the solar panels in place.
Advantages:
✔ Fast installation
✔ No roof penetration
Considerations: May not suit roofs with low load capacity or extreme weather.
Fixed systems
Fixed mounting systems provide a secure solution for solar panels on flat roofs, ideal for storm-prone areas.
Advantages:
✔ Maximum wind and snow resistance
✔ No ballast required
Considerations: Can be time-consuming on complex rooftops.
NEW: Hybrid systems
The hybrid mounting system combines ballasted and fixed options for a solid flat roof installation.
Advantages:
✔ On-site flexibility
✔ Ideal for complex layouts
Considerations: Combines both approaches while avoiding their limitations

Hybrid solar mounting system:
The smart choice for flat roof solar installations
You may have used a ballasted solar panel mounting system or our fixed method. What if you don’t have to choose? The hybrid solar mount system offers the best of both.
This system offers unmatched flexibility and efficiency, from planning to installation. It delivers long-term advantages across technical, financial, and structural aspects, making it the ideal choice for solar panel installations on flat roofs.
✔ Ultimately cost-saving, with lower material costs, faster installation than fixed systems, a reduced total price, and a quicker return on investment.
✔ Protects your roof structure by reducing unnecessary weight, preventing roof slippage and limiting the number of penetrations.
✔ Improves system stability by keeping panels secure in all weather conditions, even on weak or complex rooftops.
✔ Supports regulatory compliance by enabling easier alignment with local building codes and helping avoid costly redesigns or delays.
Approved third-party fixation solutions
Our hybrid solar panel mounting system for flat roofs uses third-party solutions such as Mataki mounting plates, Trebolit mounting plates, and CW Lundberg mounting plates. These products have been thoroughly tested with our flat roof system ValkPro+ and pitched roof system ValkPitched, confirming full compatibility. All structural loads remain safely within permissible limits, and our standard warranty conditions continue to apply in full.
