Smart Ballast Mounting for Flat Roof PV Systems

The VDV AU.ballast wing ValkPro+ is a specialised component within the ValkPro+ system, designed for flat roof solar installations that demand reliability, ease of installation, and roof surface protection. Ideal for south or east-west panel layouts, it supports structurally sound and low-ballast mounting without roof penetration.

Part of the Trusted ValkPro+ Mounting Range

Built by Van der Valk Solar Systems, the VDV AU.ballast wing ValkPro+ forms part of the widely adopted ValkPro+ flat roof system. This system is engineered to meet European safety standards and withstand challenging roof and wind loads—backed by wind tunnel testing and Eurocode compliance.

Quick Installation with Minimal Components

• Pre-mounted parts for rapid on-site assembly
• Installation speed of approx. 3 minutes per module
• Minimal number of parts simplifies logistics and handling

Low Ballast, Maximum Stability

The VDV AU.ballast wing ValkPro+ helps reduce the total ballast required thanks to aerodynamic design and optimised panel positioning. This minimises roof load, making it suitable for a wider range of roof types—including those with limited structural tolerance.

Roof-Friendly and Secure

• Flexible, soft rubber feet to absorb expansion and protect the roof
• Certified lightning protection and 100% equipotential bonding
• Optional fixation using ValkSolarFix for extra security
