Selection Tips for Ultra-High Power PV Modules
Core Screening Factors
1. Conversion Efficiency: Refer to the industry standard GB/T 9535-2018, select modules with a conversion efficiency of no less than 25.5%, which directly affects the annual power generation of the power station. Higher conversion efficiency means more power output per unit area, reducing land occupation and construction costs.
2. Power Level: Prioritize modules with a power of 700W or above, which can reduce the number of modules and brackets required for the project, thereby lowering construction and installation costs. At the same time, fewer modules also mean fewer connection points, reducing the risk of circuit failure.
3. Durability Index: Focus on parameters such as temperature coefficient, PID resistance, and mechanical load resistance. The temperature coefficient should be no higher than -0.26%/℃ to ensure stable performance in high-temperature environments. PID resistance is crucial for projects in high-humidity and high-salt areas to avoid long-term power attenuation.
4. After-Service Support: Choose brands with perfect after-service systems, including technical guidance, fault repair, and component replacement services. A quick after-sales response can minimize the downtime of the power station and ensure continuous power generation.
Common Pitfalls to Avoid
1. Overemphasizing Power Ignoring Efficiency: Some modules have high power but low conversion efficiency, which may not effectively improve power generation per unit area. It is necessary to comprehensively compare power and efficiency indicators to select products with the highest cost performance.
2. Ignoring Component Compatibility: Ultra-high power modules require matching inverters and brackets. Before purchasing, confirm whether the module is compatible with the existing system equipment to avoid additional modification costs.
3. Neglecting Brand Reputation: Choose brands with good industry reputation and mature production technology. Products from well-known brands usually have stricter quality control, reducing the risk of quality problems during operation.
