Introduction: Mounting Systems—the Backbone of Solar Projects
In any solar installation, the mounting system is the foundation of lasting performance and safety. High-quality racks protect modules from weather and secure output, making your investment reliable and future-proof.
Key Components of a Solar Mounting System
- Rail: Use corrosion-resistant aluminum alloy 6063-T5 for secure module support.
- Clamp: Stainless steel and aluminum clamps hold panel edges and centers firmly.
- Bracket: Adjusts tilt; choose aluminum alloy or galvanized steel for strength and durability.
- Fasteners: SUS304/SUS316/SUS410 stainless steel ensures reliable connections and load performance.
- Rubber Seal: EPDM rubber is recommended for waterproofing rooftop installations.
Tip: Always consider load, waterproofing, durability, and installation environment when selecting parts.
Main Applications & Mounting Types
- Rooftop Mounting Systems
- Pitched Roofs: For metal, cement, or tile roofs, hanger bolts or hooks avoid penetration, simplifying waterproofing.
- Flat Roofs: Adjustable triangle or ballasted systems optimize tilt for maximum output.
- Ground Mount Systems
- Suitable for large-scale projects, requiring strong loads and geotechnical analysis.
- Carport Mounting Systems
- Combine parking with power generation; robust structure and advanced drainage are essential.
Design & Material Selection: Key Considerations
- Structural Stability: Apply finite-element analysis; favor aluminum 6063-T5 or hot-dip galvanized Q235B steel.
- Corrosion Resistance: SUS316/SUS410 stainless steel for coastal or salty environments; anodizing or hot-dip galvanizing for long-term protection.
- Installation Compatibility: Match with mainstream PV panel sizes and adapt for all roof types.
- Waterproofing: Solar Hanger Bolt with EPDM seals delivers leak-free protection for over 20 years.
How to Choose Your Solar Mounting System
- Roof Type: Select the precise solution for each roofing material—metal tile, flat, or ground.
- Installation Environment: Use anti-corrosion materials for seaside or hot regions.
- Project Scale: Adapt design and budget for residential, commercial, and utility-scale projects.
- Ease of Installation: Prefer modular, non-penetrating designs for simple setup.
- Durability & Maintenance: Opt for fasteners and seals rated for ≥20 years.
Industry Trends
- Lightweight aluminum mounting racks are increasingly popular for corrosion resistance.
- Adjustable and tracking mounts are gaining traction as demand rises in emerging markets.
Installation FAQ
- Do I need to penetrate the roof? Metal roofs typically require bolts; flat roofs benefit from ballasted systems.
- Lifespan? Premium mounting systems last 25+ years with regular checks.
- Does tilt angle affect output? Optimal tilt matches local latitude; adjustable racks improve production.
