Verification Technical Specifications

Material Thickness: Steel plate ≥2 mm, hot-dip galvanized coating ≥60 µm (≥80 µm in coastal areas)

Load-bearing Capacity: Wind and snow load calculations shall be performed in accordance with the Photovoltaic Mounting Structure Design Standard, ensuring the mounting structure maintains a safety factor ≥1.5 under design extreme weather conditions.

Certification and Testing Reports

Solar mounting system Suppliers must provide quality system certifications such as ISO 9001, CE, and SGS.

Test reports or third-party inspection reports demonstrating resistance to wind, snow, and corrosion must be included.

Evaluating Life Cycle Cost (LCC)

Compare the total cost of the mounting structure—including purchase price, installation fees, maintenance costs, and anticipated replacement expenses—against projected power generation revenue.

Low-cost structures often incur higher long-term expenses from repairs and downtime losses, potentially yielding a lower overall ROI than slightly more expensive yet reliable solutions.

Select suppliers with a proven industry reputation.

Refer to industry reports and bid evaluation records, prioritizing companies where the "technical quality score" exceeds the "price" factor. Review supplier credit ratings issued by reputable agencies.

On-site Construction and Waterproofing Measures

When using the drilled-through mounting method, waterproof sleeves and sealant must be employed to prevent roof leakage.

For ballasted brackets, local anchoring should be added when roof load-bearing capacity is insufficient to prevent roof deformation caused by self-weight.

Post-Installation Maintenance Plan

Establish a regular inspection system for the support structure (every six months), focusing on bolt tightness, integrity of the galvanized coating, and positioning of counterweights.

Document inspection results to create a maintenance record for insurance claims and future technical improvements.
