PV Plant Certification

Photovoltaic Power Plant Certification is a systematic compliance assessment and technical validation of the entire project lifecycle (from design, construction to operation and maintenance), conducted in accordance with international standards. It culminates in the issuance of highly recognized certification, serving as authoritative international endorsement of the plant's technical reliability, safety, performance, and financial compliance. This includes design certification, construction certification, performance certification, and specialized certifications.

 

Certification acts as the "technical passport" for asset compliance and investment security. Through independent third-party verification of the entire project chain (design-construction-O&M), it significantly reduces technical risks (e.g., structural failure, fire hazards), directly enhances financing credit ratings, secures insurance benefits, and increases asset transaction premiums. It also meets global grid connection requirements, establishing an irreplaceable credit foundation for 25 years of stable returns. TÜV NORD validates that your solar power plant complies with safety, quality standards, and regulations. Through performance measurement, energy yield calculations, and on-site inspections, we provide critical decision-making support during the planning phase. We test component functionality, assess plant quality, and verify compliance with technical and safety standards.

 

Document Review

Verifies the completeness of handover documents against system file acceptance requirements, including initial or periodic plant validation records.

On-site Inspection

Comprehensive quality checks of construction, consistency, and safety configurations based on design files and standards (e.g., IEC 62446). Ensures construction quality meets specifications through statistically valid sampling and coverage principles. Continuous data evaluation guarantees high performance, minimal downtime, and fault detection, including early warnings for potential issues—providing reliable data throughout the plant's lifespan.

Performance Acceptance Test / Performance Ratio Evaluation

Conducts key performance indicator testing and analysis based on IEC 62446/IEC 61724 standards, creating customized "health checklists" for each plant. Quantitatively evaluates:

• Module degradation rates
• String dispersion levels
• Bolt torque compliance rates
• Hotspot occurrence rates
• Safety performance benchmarks
• System efficiency metrics
