Rail-based racking offers PV systems many advantages. The ability to secure the modules within the module manufacturers green zone, which ensures the highest load rating for the module and that the module warranty is maintained; load sharing, increasing the rigidity and interconnectedness of a racking system increases the load sharing which would offer the system weight reduction; ease of installation, by having continuous rails for row predetermined row spacing and ease of wire management.

TerraGen’s racking systems are designed to clamp modules in the optimal zones to ensure maximum load ratings, promoting module health and longevity.

TerraGen will go above and beyond to verify that your project loads meet the module manufacturer’s specified requirements. In situations where loads exceed the optimal zones, TerraGen can provide solutions to increase the number of rails and clamp locations to provide the best possible load rating, collaborating with you to obtain manufacturer approval.

TerraGen offers racking solutions for every roof type. Whether you need a unique attachment for a pitched roof or have load constraints on a flat roof, our systems provide the flexibility to overcome these challenges. With our unparalleled design support, you are assured of finding the perfect solution.

TerraGen’s TGR flat roof system is exceptionally versatile. The rail-based design provides structural rigidity in both directions, ensuring optimal load sharing and reducing ballast requirements. This system is fully adaptable to your preferred tilt angle and row spacing, maximizing your layout and PV generation for the best overall rate of return. Additionally, the system can address various building structural challenges by aligning base rails with specific load transfer points, such as OWSJ.

TerraGen’s TGR flat roof system has 3 options for uplift resistance:

• Ballast: PV array resists uplift and sliding with ballast weight typically in the form of concrete blocks secured to the racking system.
• Mechanical Attachment: PV array resists uplift and sliding with anchors which fasten the system to the roof.
• Hybrid: PV array resists uplift and sliding with a combination of ballast weight and anchors.

With TerraGen’s TGR flat roof system, you can optimize your layout for a reduction in material, installation and overall cost.

• Portrait orientation is optimal for a rail-based system, reducing the amount of overall material while increasing the walkways between rows.
• Interconnected square arrays will offer the best load sharing to reduce ballast requirements. The more modules you can put into the main body of an array (instead of a row jutting out), the better. This will also help with installation efficiencies.

TerraGen’s TGR flat roof system is a make-to-order design where you choose the parameters that best fit your requirements for layout, production goals, or any other challenges that need to be overcome.

The TGR system can tilt from 5-20° in portrait or 5-35° in landscape orientation.

TerraGen’s TGR system can overcome building structural challenges, often without the addition of mechanical attachments. The flexibility of the system allows you to choose the tilt angle and row spacing which can help you overcome the structural challenges.

TerraGen’s rubber pad is required to protect the roof membrane from the metal racking. It is always recommended that the roof membrane manufacturer be consulted to ensure that they will honour the roof warranty. It is common that they will require slip sheets of the exact roofing material placed under the rubber locations to act as a sacrificial layer.

The TGR system can accommodate minor roof undulations, and will further conform to the roof when ballast and modules are installed. The rigidity of the base rail allows it to span small valleys up to a couple of feet long or those located under an interrow.

However, additional measures should be taken if there is no support within ~16 inches of a tilt assembly joints (load transfer points) or beneath ballast locations to ensure the blocks are secured tightly. In such cases, additional measures are required:

For very minor undulations: Stack rubber pieces to reach the elevation of the base rail using the extra pieces provided.

For extreme cases: If the gap is more than a couple of inches or there are point loading concerns, insert a rigid material as a shim in the appropriate locations. Rigid insulation wrapped in UV-resistant material can be an effective solution.

It is important to note that slopes can impact the even distribution of system loading. If there are concerns about localized loading, the methods described should mitigate these issues. If concerns persist, consult the building structural engineer for appropriate measures to be taken.
