1. Product Overview
 
The ALUMSOLAR Flat Roof Solar Mounting System is a high-performance, modular installation solution specifically designed for commercial and industrial building flat roof environments. Upholding the ALUMSOLAR brand's commitment to quality, reliability, and efficiency, this system utilizes premium materials and precision engineering to provide a solid foundation for photovoltaic (PV) power plants for over 25 years. Its non-penetration design concept, using concrete ballast blocks or safe connections to the roof structure, perfectly protects roof integrity and is suitable for various types of flat roofs.
 
2. Core Advantages
 
Exceptional Stability: Optimized triangular structure mechanics, validated by wind tunnel testing, capable of withstanding extreme wind and snow loads.
Superior Corrosion Resistance: Main structure made of 6063-T5 high-strength aluminum alloy; critical connectors are 304 or 316 stainless steel, ensuring the system remains free from rust concerns throughout its entire lifecycle.
Rapid Installation: Modular design and pre-assembled components significantly reduce installation complexity, saving up to 40% installation time and labor costs.
Full Compatibility: Supports the vast majority of brands and sizes of PV modules on the market, flexibly adapting to different roof layouts and tilt angle requirements.
Worry-free Maintenance: Welding-free design; all connections are adjustable and detachable, facilitating future roof maintenance and system expansion.
 
3. Detailed Main Components
Triangle Bracket
Description: The core support component of the system, formed from high-strength extruded aluminum alloy or stamped galvanized steel, creating a stable triangular structure.
Features: Precision slotted hole design supports stepless adjustment, perfectly adapting to different module tilt angles. The base is pre-drilled for direct connection to ballast bases or roof attachments.
Aluminum Rail
Description: The primary load-bearing and fixing rail for PV modules.
Features: Made of 6063-T5 aluminum alloy with anodic oxidation treatment, offering high strength, light weight, and excellent corrosion resistance. The unique "T-slot" design provides an integrated sliding channel for all bolt connections, enabling fast and flexible positioning.
Mid Clamp
Description: Used to secure the middle section of two adjacent PV modules.
Features: Made of high-quality stainless steel with an integrated anti-scratch pad to protect the module frame and ensure even distribution of clamping force. Easily inserted into the rail T-slot and tightened with a bolt for effortless installation.
End Clamp
Description: Used to secure the outermost PV modules of the array.
Features: Made of the same material as the mid clamp, designed to provide stronger clamping force, ensuring the absolute security of the array's edge modules.
Grounding Lug (Ground Lug)
Description: A dedicated component used to achieve equipotential bonding for the system.
Features: Made of stainless steel with a serrated design that penetrates the oxide layer on the rail surface to form a low-resistance, reliable electrical connection. Simply insert it into the rail slot and tighten the bolt to complete grounding, complying with electrical safety standards.
Fixed Nut (T-Bolt)
Description: A pre-assembled nut specifically designed for T-slot rails.
Features: Can be slid to any position after being placed in the slot and locked by rotating 90 degrees. Used in conjunction with clamps, grounding lugs, and other accessories for fast and secure connections.
Rail Splice (Rails Splice)
Description: Used to extend and connect two rails, ensuring longitudinal strength and continuity.
Features: Internal sleeve design inserts into both ends of the rails and is secured with high-strength bolts, making multiple connected rail sections as sturdy as a single piece and ensuring the structural integrity of the entire array.
