Revolutionizing Solar Power: HJT Modules Lead Energy Efficiency
Revolutionizing Solar Power: HJT Modules Lead Energy Efficiency
As the solar industry evolves, new technologies like Heterojunction (HJT) are taking center stage, driving greater efficiency and power generation capabilities. Recent findings reveal that HJT modules outperform traditional BC modules with a remarkable 3.85% increase in power generation per watt. This performance boost demonstrates the potential of innovative technologies in redefining the photovoltaic landscape.
Unveiling High Efficiency Through Rigorous Empirical Validation
The empirical power station experience showcases a crucial aspect in solar technology advancement. Examined under ideal conditions, the HJT modules were subjected to comprehensive testing. The location features an average annual solar irradiance of 1268 kWh/m², combined with a climate characterized by a humid subtropical atmosphere.
The field trial consisted of installing 210 HJT and 182 BC modules at a tilt angle of 15°, positioned 1.5 meters above ground. By using a state-of-the-art outdoor photovoltaic evaluation system, real-time performance was tracked with great precision, enabling a detailed analysis of power generation efficiency.
Superior Power Generation Driven by Heterojunction Technology
The advantages of HJT technology extend far beyond traditional capabilities. The bifacial design of HJT modules significantly improves energy yield, especially in reflective environments, achieving a remarkable backside gain of over 90%. This gain outstrips the performance of BC modules, which sees a gain of around 70%, consistently enhancing energy production.
Temperature Stability Enhances Performance
Another noteworthy feature is the -0.24%/°C temperature coefficient for HJT modules. This characteristic means that HJT modules are less affected by heat compared to their BC counterparts, which have a coefficient of -0.26%/°C. In practical terms, this translates to a potential 1.2% to 1.8% increase in energy production during the hot weather season, allowing for reliable performance throughout the year.
Enhanced Power Generation with Red Light Sensitivity
The strategic use of advanced materials within HJT solar cells also boosts their sensitivity to red light wavelengths. This trait results in longer durations of effective power generation, particularly in the early morning and late afternoon, significantly benefiting users seeking maximum solar output.
These technological advantages not only promise sustainable energy production throughout the operational life of solar installations but also enhance confidence in the effectiveness of HJT technology. As the shift towards n-type technologies gathers speed, the results from Risen's HJT modules underscore the industry's movement towards prioritizing efficiency over mere cost considerations. This strategic change is expected to foster a more robust global energy transition.
