From Wind Loads to Corrosion – Key Criteria for Selecting a Reliable Solar Structure

2026-04-22 08:56

When building a photovoltaic power station, the solar panel mounting structure is far more than just a “holder” for your panels—it is the critical safety backbone that determines the project’s stability, lifespan, and performance for decades. Poorly designed or low-quality structures can lead to catastrophic failures: panel uplift during storms, structural collapse under heavy snow, corrosion-induced weakening in coastal areas, or even fire hazards from electrical grounding issues.

So, how do you choose a solar structure that truly guarantees your PV power station’s safety? At Jinda Solar, we design our mounting systems to meet the strictest global safety standards, backed by real-world testing and 6GW+ of global project experience. Here’s what we recommend prioritizing:

1. Wind & Snow Load Compliance – The Non-Negotiable Foundation

The most common cause of solar structure failure is inadequate load resistance. Your mounting system must be engineered to withstand the maximum wind speed (e.g., 42m/s for inland areas, up to 60m/s for coastal zones) and snow load (e.g., 1.0 kN/m² for cold regions) specific to your project location, in compliance with standards like AS/NZS 1170, EN 1991-1-3/4, and IEC 61215.

At Jinda Solar, every structure undergoes rigorous finite element analysis (FEA) testing and third-party wind tunnel simulations. For example, our ground-mounted systems are designed with a safety factor of ≥2.5, ensuring they remain stable even during extreme weather events.

2. Corrosion Resistance – Built to Last in Every Climate

Corrosion is the silent killer of solar structures, especially in humid, coastal, or industrial environments. The material you choose directly impacts long-term safety:

Hot-dip galvanized steel: Ideal for inland projects, with a zinc coating ≥85μm for 25+ year corrosion resistance.
6063-T5 anodized aluminum: Perfect for coastal or high-humidity areas, forming a natural protective oxide layer that resists salt spray and rust.
Stainless steel (SUS304/SUS316): Used for critical fasteners and components, ensuring zero corrosion in even the harshest conditions.

All Jinda Solar structures undergo salt spray testing (≥1000 hours) and ISO 9227 compliance, so you never have to worry about structural weakening from rust.

3. Structural Design & Installation Precision – Avoid Hidden Risks

Even high-quality materials fail if the design is flawed. Look for:

Proper load distribution: The structure must transfer panel, wind, and snow loads evenly to the building or ground, avoiding stress concentrations that cause fatigue cracks.
Grounding & electrical safety: Aluminum rails must include integrated grounding features (e.g., serrated washers) to ensure low resistance (≤0.02Ω) and prevent electrical shock or fire hazards.
Tool-free installation: Pre-assembled components eliminate on-site welding or drilling errors, ensuring every bolt and bracket is installed to spec.

Our tile roof mounts, for example, use specialized hooks that anchor directly to roof rafters (not tiles), preventing roof leaks and structural damage while meeting wind uplift requirements.

4. Compliance & Certification – Independent Validation of Safety

Never skip third-party certification. Look for structures tested and certified to meet:

IEC 61215 (module safety)
IEC 62109 (mounting system safety)
EN 50549 (grid connection safety)
Local building codes (e.g., ASCE 7 in the U.S., Eurocode 3 in Europe)

Jinda Solar’s products are certified by TÜV, SGS, and other leading bodies, giving you peace of mind that every component meets international safety standards.
