Thanks to Valin New Energy’s unique TPO membrane roof photovoltaic bracket solution, which adopts an integrated membrane-rail design. After integration, the brackets are directly fixed on the surface of the roof TPO/PVC membrane by hot air welding, without drilling holes on the roof for fixation, avoiding damage to the original roof TPO waterproofing and eliminating leakage hazards. Meanwhile, each integrated bracket can easily withstand wind uplift loads in extreme windy weather with a minimum super strong adhesion of 200KG. Valin New Energy participated in the entire project implementation process, from the design of membrane roof brackets and on-site pull-out tests to factory prefabrication, production and assembly, as well as on-site welding construction, fully ensuring the reliable and efficient execution of every link of the project. For this reason, Valin New Energy has received high recognition from the power station investor and Shanghai Jahwa.

Valin New Energy’s TPO/PVC membrane roof photovoltaic bracket solution directly addresses the waterproofing and construction difficulties of membrane roofs. With highly integrated and modular integrated brackets, it empowers the installation and construction of various membrane roof photovoltaic projects. Meanwhile, relying on Valin New Energy’s professional membrane roof construction organization, it ensures the efficient operation of TPO/PVC membrane roof photovoltaic power stations for 25 years, injects new vitality and momentum into the development of building-integrated photovoltaics, and helps achieve the dual carbon goals.

1. Overview of TPO/PVC Membrane Roof

2. Challenges in Photovoltaic Installation on TPO/PVC Membrane Roofs

• Piercing the membrane with fasteners to fix brackets to purlins or steel plates leads to potential water leakage if waterproofing at the pierced position is improperly handled.
• Directly adhering brackets to the membrane surface may cause the waterproof membrane at connection points to tear due to excessive wind force.

3. Introduction to Valin New Energy’s Integrated Photovoltaic Bracket System

4. Core Advantages of the System

4.1 No Drilling, Leakage Prevention

4.2 Stable Load-Bearing Performance

• No additional ballast is required, ensuring linear load distribution and improving roof structural stability.
• The additional load per square meter is only 2KG, meeting the requirements of all concrete, color steel tile and wood structure roofs with load restrictions.

4.3 Convenient Installation and Strong Adaptability

• The integrated membrane-rail design enables high integration of the membrane and bracket rail. It is modular, with one specification suitable for various situations, easy to install, and no on-site processing is needed.
• It is compatible with all types and specifications of photovoltaic modules.

4.4 Reusable and Wind-Resistant

• The integrated bracket rail is detachable, allowing easy removal when replacing the original roof membrane and reuse after installing a new membrane.
• A single bracket can withstand an effective pull force of over 100 kilograms without peeling off from the membrane, ensuring the photovoltaic modules can withstand strong winds under four-point force. For coastal or high-wind areas, pre-reinforcement can be carried out if the membrane’s connection point peel strength is weak.
