Conversion efficiency: Its Vertex N 725W module uses N-type TOPCon technology, with a maximum conversion efficiency of 26.3%. Optimized current distribution design reduces power loss caused by shading, improving overall power generation efficiency.

Quality stability: The module has passed TÜV Rheinland and UL certifications, with excellent anti-PID and anti-leakage performance. First-year power attenuation is less than 2%, and annual attenuation after that is less than 0.4%.

Cost-effectiveness: Priced at approximately $0.195 per watt, it is slightly higher than the industry average. However, its long-term stability and high power generation density make it suitable for large-scale projects with sufficient budgets.

Brand reputation: It has ranked among the top three in global module shipments for consecutive years, with a service network covering over 100 countries and regions, providing comprehensive technical support.

Disadvantages: High product prices increase initial investment for small and medium-sized projects, and customized product delivery cycles are relatively long, potentially delaying project progress.

3. JinkoSolar Holding Co., Ltd.

JinkoSolar is a global PV enterprise with strong R&D and production capabilities. Its high-power modules are favored for their high power output and reliable performance across various project scenarios.

Conversion efficiency: Its Tiger Pro 720W module adopts N-type TOPCon technology, reaching a maximum conversion efficiency of 26.2%. A multi-busbar design reduces internal resistance, improving power output under low-light conditions.

Quality stability: The module has passed IEC and UL certifications, with a temperature coefficient of -0.30%/℃, better than the industry average of -0.32%/℃, ensuring stable output in high-temperature environments.

Cost-effectiveness: Priced at approximately $0.185 per watt, it strikes a balanced performance-cost ratio, suitable for most domestic and international photovoltaic projects.

Brand reputation: It has maintained top global shipment rankings for years, with a 92% customer retention rate according to the 2026 Global PV Enterprise Customer Survey.

Disadvantages: After-sales service networks in some domestic third- and fourth-tier cities are incomplete, leading to slower response times for local user needs.

4. LONGi Green Energy Technology Co., Ltd.

LONGi Green Energy is a leading PV enterprise focusing on silicon materials and high-efficiency cells, known for advanced technology and reliable product quality.

Conversion efficiency: Its Hi-MO 7 715W module uses HPBC technology, eliminating front electrode shading to achieve a maximum conversion efficiency of 26.4%, significantly improving light absorption and power output.

Quality stability: The module has passed 12,000 hours of damp heat tests and 6,000 hours of mechanical load tests. First-year power attenuation is less than 1.5%, and annual attenuation after that is less than 0.35%, outperforming most industry peers.

Cost-effectiveness: Priced at approximately $0.19 per watt, it is slightly above the industry average. Its superior long-term power generation stability brings higher long-term returns for users.

Brand reputation: It boasts strong R&D capabilities with numerous core patents, and its after-sales team provides nationwide technical support with a 48-hour response time.

Disadvantages: The product line of 700W+ high-power modules is relatively single, lacking customized options to meet diverse project requirements.
