Key Specifications and Performance Metrics

LONGi panels are characterized by impressive specifications, including high efficiency ratings (typically above 20%) and robust power outputs. Key metrics to consider include:

• Power Output: Ranges from 350W to over 500W per panel, depending on the model.

• Temperature Coefficient: Typically around -0.35%/°C, indicating better performance in high temperatures compared to some competitors.

Advanced Technologies Used by LONGi

1. PERC (Passivated Emitter Rear Cell) Technology

LONGi employs PERC technology in their solar cells, which enhances efficiency by allowing light to reflect off the rear of the cell back into the silicon layer. This design minimizes energy loss and increases overall energy yield, making LONGi panels particularly effective in various lighting conditions.

• Increased Light Reflection: By reflecting light from the rear of the cell back into the silicon, PERC technology maximizes the use of available sunlight, improving overall energy conversion efficiency.

• Higher Energy Yield: This enhanced light trapping reduces energy losses, enabling LONGi panels to generate more power per square meter compared to traditional solar cells.

• Better Low-Light Performance: Panels perform better in low light and diffused sunlight conditions, such as cloudy or early morning/evening hours.

• Improved Durability: The design enhances the overall lifespan of the panel by reducing the thermal degradation that typically occurs in conventional cells.

2. HJT (Heterojunction Technology)

HJT combines the benefits of crystalline silicon and thin-film solar cells, resulting in higher efficiency and better temperature performance. This technology allows for a reduction in material usage while improving energy yield. LONGi’s adoption of HJT technology represents a significant advancement in solar technology, offering better performance and durability.

• Higher Efficiency: HJT panels combine the best of crystalline silicon and thin-film technologies, achieving higher efficiency levels (often above 22% in high-performance models).

• Excellent Temperature Coefficient: HJT technology excels in high-temperature conditions, showing less efficiency loss in hot climates compared to conventional silicon panels.

• Reduced Material Use: The design optimizes the use of silicon and reduces material wastage, making it a more cost-effective and eco-friendly technology.

• Better Light Absorption: By combining two types of solar technologies, HJT panels have superior light absorption characteristics, improving energy conversion rates.

3. Innovations in Cell Design and Manufacturing Processes

LONGi continually invests in R&D to enhance cell design and manufacturing processes. Innovations include improved cell layouts, advanced surface texturing, and automated production techniques that ensure high-quality output and reduce defects. These enhancements lead to more efficient energy production and increased longevity of the panels.

• Improved Cell Layout: Optimized cell structure and design increase energy capture while reducing internal resistances that limit energy production.

• Advanced Surface Texturing: Texturing on the cell surface enhances light trapping, leading to higher absorption of sunlight and improved energy efficiency.

• Automated Production: Advanced automated processes ensure precision, improving consistency in panel quality, reducing defects, and enhancing manufacturing efficiency.

• Reduced Defects and Better Quality Control: Enhanced manufacturing techniques reduce the chances of cell breakage or defects, resulting in higher yields and better long-term performance.

• Scalable Production: With the integration of advanced manufacturing methods, LONGi can scale production without compromising panel quality, making their technology more accessible globally.
