Coastal solar projects face a relentless enemy: saltwater corrosion. Traditional steel and aluminum mounts, despite galvanization or coatings, often succumb to rust, leading to costly repairs and downtime. For EPCs and developers, selecting the right mounting isn’t just about durability—it’s about maximizing ROI over 25+ years. Here’s how to choose wisely.
Key Considerations for Coastal Solar Mounting System
Corrosion Resistance is Non-Negotiable for PV Racking
The Science of Saltwater Damage: Salt accelerates electro chemical reactions, causing steel to rust and aluminum to pit. Even galvanized coatings degrade over time.
FRP’s Edge: Fiber Reinforced Polymer (FRP) composites are inherently corrosion-proof, with no metallic components to corrode. No coatings, no maintenance—just decades of reliable performance.
Longevity and Low Maintenance
Zero Upkeep: Unlike steel, FRP requires no repainting or rust repairs.
Certified for 25+ Years: FRP’s saltwater resistance is validated by 5,000+ hour salt spray tests (ASTM B117).
Structural Integrity in High-Wind Zones
Strength Without Weight: FRP’s high strength-to-weight ratio (1.13x steel’s tensile strength at 1/4 the weight) ensures stability in storms.
Modular Flexibility: Pre-assembled FRP modules adapt to uneven terrain, reducing installation time by 30% vs. bulky steel systems.
FRP vs. Traditional Materials: The Coastal Showdown
Feature FRP Composite Steel/Aluminum
Corrosion Resistance ✅ No rust, ever ❌ Coating degradation
Weight 75% lighter Heavy, costly to ship
Maintenance Zero Annual inspections
25-Year TCO Lower Higher (repairs, replacements)
