27.59MW Sunner Group Food Processing Plant Roof Mounting System | Jiangxi, China
April 01, 2026
1. Project Overview
•Project Background: The project is located in Jiangxi Province, and forms an important part of Sunner Group’s green supply chain development strategy. The distributed PV project cluster delivered by Antaisolar for Sunner Group has been fully commissioned, with a total installed capacity of 27.59MW. Among them, the distributed PV project at the Jiangxi Sunner food processing facility integrates clean energy into production processes through multi-scenario mounting solutions, supporting the company’s transition toward low-carbon operations and sustainable development.
• Project Requirements: The project required the installation of distributed PV systems across two different types of rooftops within the food processing facility. The core requirement was a customized mounting solution capable of safely adapting to diverse roof structures, strictly meeting load requirements, and enabling efficient deployment. Specifically, the solution needed to: (1) Apply dedicated installation technologies for both metal roofs and TPO roofs, ensuring non-destructive installation and waterproof protection. (2) Be designed in strict compliance with 0.31 kN/m² wind and snow load requirements, ensuring long-term structural safety and reliability. (3) Support a “self-consumption with surplus electricity fed into the grid” model to maximize cost savings for the enterprise.
2. Project Challenges
2.1 Technical Adaptation and Protection for Diverse Rooftop Types
•The facility includes both metal sheet roofs and TPO membrane roofs, each requiring different connection methods, load distribution strategies, and waterproof protection measures. Metal roofs require non-penetrative clamping solutions. TPO roofs must avoid any penetration to maintain waterproof integrity and longevity.
2.2 Structural Safety and Operational Stability in Food Processing Environments
•Food processing facilities demand extremely high standards for safety and operational stability. The PV system must ensure absolute structural safety under 0.31 kN/m² wind and snow loads, while installation activities must not interfere with sensitive production processes.
2.3 Integrated Design and Efficient Delivery Across Multiple Scenarios
•The project required parallel design and construction of two mounting systems for different roof types. Coordination between solutions was essential to ensure consistency, installation quality, and efficient delivery to achieve rapid grid connection.
3. Solution
Antaisolar provided a multi-scenario customized mounting solution based on a single-span vertical layout, tailored to the specific requirements of the food processing facility.
3.1 Metal Roof Solution: Kliplok Clamp and High-Strength Rail System
•A 50 mm kliplok clamp is used to securely attach to the metal roof ribs via mechanical clamping, achieving non-penetrative installation and preserving roof waterproof integrity.
•The main load-bearing structure utilizes H aluminum rails with a wall thickness of 1.2 mm, combined with 60 mm mid and end clamps for secure module fixation. The system is designed in strict accordance with 0.31 kN/m² wind and snow load requirements, ensuring structural safety and stability.
3.2 TPO Roof Solution: Adhesive Base and Square Rail System
•A specialized adhesive base is used, bonded to the TPO membrane with high-strength structural adhesive, achieving non-penetrative installation without damaging the waterproof layer.
•The load-bearing structure uses square aluminum rails with a wall thickness of 1.35 mm, offering higher bending stiffness. Combined with 60 mm mid and end clamps, the system ensures both load compliance and long-term reliability.
3.3 Efficient Project Execution: Standardized Modular Installation
•Both mounting systems adopt a modular design, with clamps/bases, rails, and clamps manufactured and pre-assembled in the factory. On-site work involves only simple assembly and fastening, significantly simplifying installation.
•Clear installation guidelines and on-site technical support enable multi-team, multi-zone parallel construction, effectively shortening the overall project timeline and ensuring rapid grid connection.
4. Project Results
•Successful Commissioning and Stable Operation: The 27.59MW distributed PV project at the Sunner food processing facility has been successfully grid-connected and is operating reliably. The multi-scenario mounting solution provided by Antaisolar effectively addressed the technical challenges of different roof types, delivering precise adaptation, high safety, and efficient installation, while ensuring a stable supply of green electricity.
•Significant Economic and Environmental Benefits: Operating under the “self-consumption with surplus power export” model, the system directly supplies clean electricity to food processing operations, significantly reducing electricity costs. The project generates substantial green energy annually, reducing carbon emissions and supporting low-carbon production in the food processing sector. This project successfully demonstrates the deep integration of photovoltaic power generation with the food processing industry. It provides a replicable model for large-scale food manufacturers to develop green supply chains, achieve energy savings and emission reduction targets, and accelerate sustainable transformation—offering strong industry reference value.
