Valin Energy has officially launched the RailBase™ Membrane Roof PV Mounting System Technical White Paper. The document systematically presents core technologies, R&D frameworks, certification standards, and global project practices for non-damaging installation on TPO/PVC membrane roofs. It sets a replicable technical benchmark for the global distributed solar industry and further consolidates Valin Energy’s leading position in the membrane roof PV mounting sector.
Since 2021, Valin Energy has focused on the industry’s key challenge: developing non-damaging installation techniques for TPO/PVC membrane roof PV mounting systems. Continuous R&D investment has solved four major technical pain points: roof waterproof damage, wind load failure, uneven load distribution, and poor module compatibility.
After years of in-depth research, repeated rigorous testing, and international authoritative certification, the company launched the RailBase™ (V-NP) non-penetrating membrane roof mounting solution. To date, Valin Energy has delivered over 100MW of membrane roof dedicated PV mounting systems worldwide, with projects across Asia, Europe, America and other regions, earning wide recognition from global clients.
The newly released RailBase™ Technical White Paper is a comprehensive summary and open sharing of Valin Energy’s membrane roof solar technology expertise. It elaborates on the core principles of thermal welding non-penetrating installation, material innovation, and structural mechanical design. The paper also outlines the full-process quality control system from laboratory R&D and prototype testing to mass production.
It publicly discloses test data certified to European standards including ETAG 006, EN 16002, EN 12316-2 and EN 12317-2, fully verifying the system’s safety, reliability and technical advancement.
As the core highlight of the white paper, the RailBase™ (V-NP) Non-Penetrating Membrane Roof Mounting System is an innovative thermally welded solution specially designed for TPO/PVC/EPDM flexible membrane roofs. It features five core strengths: no penetration, no ballast, high compatibility, long-term durability and fast installation. It fully meets global distributed solar demands for 100% original roof waterproof retention, superior wind and snow resistance, wide module compatibility and convenient maintenance.
Core Technical Advantages of RailBase™
100% Non-Damaging Installation, Permanent Waterproof Integrity
Adopting thermal welding instead of traditional drilling or ballast mounting. It requires no penetration of the waterproof layer, completely eliminating leakage risks and preserving the roof’s original waterproof performance 100%. Fully compatible with all mainstream TPO/PVC membrane roofs.
Ultra-Lightweight Design with Even Roof Load Distribution
The system weighs only 1 kg per square meter. Loads are linearly distributed without local concentration. It avoids roof sagging and water pooling, protects insulation layers, and prevents compression on membrane seams, extending the service life of both the roof and PV system.
Highest Safety Level with Strict International Certifications
Fully complies with wind resistance requirements of European standard EN 1991-1-4. It has passed dynamic wind resistance tests per ETAG 006 & EN 16002, as well as static tensile and peel tests per EN 12316-2 & EN 12317-2, delivering industry-leading wind and snow load performance suitable for complex global climate conditions.
Full PV Module Compatibility & High Installation Efficiency
Compatible with all mainstream solar modules on the market and supports multi-directional layout to adapt to various roof sizes and power generation needs. The ready-to-install design requires no special tools, boosting installation efficiency by over 50% and greatly shortening project cycles.
Strong Scalability & Wide Application
Easily compatible with auxiliary accessories such as cable trays, maintenance walkways and inverter brackets. Ideal for commercial buildings, industrial factories and logistics warehouses, delivering an integrated solution for power generation and daily operation maintenance.
A senior technical executive at Valin Energy commented:
“The release of the RailBase™ Technical White Paper represents both our years of technological achievement and our commitment to open industry collaboration. The membrane roof solar market continues to expand, yet unified technical standards and reliable non-penetrating solutions have long been lacking. By sharing our technical experience, test data and global project practices through this white paper, we aim to drive standardization of membrane roof solar technology and support high-quality development of the global distributed PV industry.”
As of May 2026, Valin Energy’s RailBase™ (V-NP) system has been deployed in projects exceeding 100MW worldwide, covering Europe, Southeast Asia, the Middle East and North America. Adopted by renowned global EPC firms and commercial property owners, all operational projects maintain zero leakage, zero failure and stable high power output, fully validating the technology’s reliability across global markets.
Moving forward, Valin Energy will continue increasing R&D investment based on the RailBase™ Technical White Paper, optimizing product performance and expanding application scenarios. Leveraging its global delivery experience and local service network, the company will provide worldwide clients with advanced, reliable and cost-effective membrane roof PV mounting total solutions, contributing to global energy transition and carbon neutrality goals.
