Heterojunction Technology Empowers Photovoltaic Industry Shift
In the bustling city of NINGBO, China, a significant milestone in the photovoltaic industry is underway. As the industry transitions into the n-type era, Heterojunction (HJT) technology is making waves with its remarkable performance. Recent data from the Ningbo empirical power station operated by Risen Energy demonstrates the superiority of HJT modules over BC modules, with a 3.85% higher single-watt power generation and a peak daily gain of 9.97%. These results underscore the exceptional power generation capabilities of HJT technology.
Unveiling Superior Efficiency Through Empirical Validation
Situated in Ningbo, the empirical power station experiences various environmental conditions, including an average annual irradiance of 1268 kWh/m² and an average temperature of 15°C. The station’s rigorous empirical project involved installing 210 HJT and 182 BC modules vertically on fixed racks at a 15° tilt angle. Utilizing a high-precision outdoor photovoltaic module evaluation system, the performance of the modules was accurately tracked in real-time, showcasing their power generation capabilities.
Superior Power Generation Driven by High-Performance Heterojunction Technology
HJT modules offer several advantages, including a 90%+ backside gain that maximizes energy yield, especially in high-reflectance environments. With a temperature coefficient of -0.24%/°C, HJT modules outperform BC modules in high-temperature conditions, showing a daily power generation increase of 1.2% to 1.8%. Additionally, the red light band response of HJT modules enhances power generation in the morning and evening, delivering long-term benefits to customers.
Redefining Photovoltaic Technology Value
The empirical data from the Ningbo power station validates the superior power generation capabilities of HJT technology, setting a new standard for the industry. As n-type technology gains momentum, Risen’s HJT modules are driving the industry towards an ‘efficiency priority’ approach, ushering in a more sustainable future for global energy transition.
