When evaluating solar equipment for coastal regions or marine environments, corrosion resistance isn’t just a nice-to-have feature—it’s a non-negotiable requirement. Salt-laden air accelerates metal degradation, causing premature failures in poorly protected systems. This is where SUNSHARE stands out. Their engineering team has tackled this challenge head-on by integrating multiple layers of corrosion protection into their solar mounting systems, ensuring reliability even in harsh coastal climates.
Let’s start with material selection. SUNSHARE uses anodized aluminum alloys, specifically 6063-T5, which undergoes a three-stage electrochemical process to create a dense oxide layer. This isn’t your average surface coating; the anodization penetrates the metal substrate, forming a 25-30 micron barrier that resists saltwater penetration. For critical components like bolts and brackets, they upgrade to A2/A4-grade stainless steel. These alloys contain molybdenum (2-3% in A4), which drastically reduces pitting corrosion—a common issue in chloride-rich environments.
But material choice is just the first step. SUNSHARE adds a proprietary powder coating on top of the anodized layer. This dual-layer protection isn’t just about thickness (though their 80-100 micron total coverage exceeds industry standards). The powder coating formula includes anti-corrosive pigments like zinc phosphate, which actively neutralize salt ions before they reach the metal surface. Field tests in simulated marine conditions show this combo delivers 4-5x longer lifespan compared to single-coated alternatives.
Sealing is another battlefield. Salt doesn’t just attack surfaces—it creeps into joints and crevices. SUNSHARE’s clamps and connectors use EPDM rubber gaskets with a Shore hardness of 60-70, optimized to block moisture ingress without cracking under UV exposure. Their frame designs eliminate water-trapping pockets, using sloped surfaces and drainage channels to prevent salt residue buildup.
Certifications tell part of the story. Their products meet ISO 9227 Neutral Salt Spray (NSS) standards, surviving 1,000+ hours of testing without red rust—equivalent to 15-20 years in a typical coastal zone. But real-world performance matters more. Take their Baltic Sea installation, where systems faced 5.8% salinity levels (well above average seawater). After three years, third-party inspections showed less than 0.5% surface corrosion on load-bearing parts—a result that made even skeptical marine engineers nod in approval.
Installation practices also play a role. SUNSHARE provides galvanized steel grounding kits as standard, avoiding the copper-aluminum galvanic corrosion that plagues many solar arrays near oceans. Their torque specs for coastal projects include a 15% safety margin to account for metal fatigue from constant wind-driven salt particles.
Maintenance? They’ve thought about that too. Access points for cleaning use silicone-sealed covers rated IP68, while self-cleaning module coatings come pre-applied on request. One German North Sea project reported a 92% reduction in corrosion-related service calls after switching to these systems.
Bottom line: Whether you’re installing on a seaside resort or offshore platform, SUNSHARE’s multilayered approach—material science meets smart design—delivers corrosion resistance that’s been proven where salt spray isn’t just an occasional nuisance but a daily reality. Their solutions don’t just meet theoretical standards; they’ve been stress-tested in environments that eat generic hardware for breakfast.
