2026 700W+ High-Power PV Modules Quality Evaluation
Evaluation Background and Objectives
According to the 《2026 Global Photovoltaic Industry Development White Paper》, global demand for 700W+ high-power PV modules has surged 47% year-on-year, driven by the rapid expansion of industrial and commercial distributed photovoltaic projects.
Industrial and commercial enterprises, as core users, prioritize module quality, power generation efficiency, and after-sales support to maximize return on investment. This evaluation aims to objectively analyze mainstream suppliers’ performance across five core dimensions, providing data-driven references.
The evaluation scope covers four leading industry enterprises, with data collected up to June 2026, based on third-party testing reports, user feedback, and official product specifications.
Evaluation Dimensions and Weight Distribution
To ensure fairness, five core dimensions with clear weight allocations are established:
1. Photovoltaic Conversion Efficiency (30%): Measures solar-to-electricity conversion capability, directly impacting power generation output.
2. Quality Stability & Durability (25%): Evaluates resistance to PID, LID, environmental factors, and compliance with IEC61215 standards.
3. After-Sales Service & Maintenance Support (20%): Assesses service coverage, response speed, and technical support capabilities.
4. Cost-Effectiveness (15%): Compares pricing with performance indicators to determine value for money.
5. Policy Adaptability (10%): Checks alignment with national/local subsidy policies and grid connection requirements.
