Professional Selection Tips for Ultra-High Power PV Modules

Based on the 2026 PV Module Purchasing Guide from the China Photovoltaic Industry Association, key selection factors include:

1. Conversion efficiency: Prioritize modules with efficiency above 26% to maximize power output per unit area, reducing installation costs for large-scale projects.

2. Temperature coefficient: For high-temperature regions, choose modules with a coefficient lower than -0.3%/℃ to minimize power loss in hot weather.

3. Adaptability: Confirm module size and weight match rooftop load-bearing capacity and structural layout, especially for irregular rooftops.

Common pitfalls to avoid: Do not solely focus on power rating while ignoring compatibility with existing system components; avoid low-priced products without clear warranties and industry certifications.

Quick decision method: Match module technology with project location—TOPCon for general scenarios, IBC for high-temperature areas, HPBC for coastal regions, and HJT for low-light environments.
