💡 N-Type Technology – A Photovoltaic Revolution

N-Type cells represent the next generation of photovoltaic technology, offering an advanced alternative to traditional P-Type modules. The key difference lies in the chemical composition used in their production:

🔹 P-Type cells contain boron, creating a positively polarized structure that makes them more prone to degradation and efficiency loss.
🔹 N-Type cells use phosphorus, which has an extra electron compared to silicon. This results in negative polarization, leading to higher efficiency, greater degradation resistance, and improved solar energy conversion.
🔹 Advantages of N-Type Cells in the SUNPRO 580W Silver Panel
✅ Higher conversion efficiency → More energy generated from the same amount of sunlight
✅ Reduced absorption loss → Improved light absorption on cloudy days
✅ Greater contamination tolerance → Increased resistance to micro-cracks in the silicon structure
✅ Superior resistance to LID & PID degradation → Ensures long-term high performance
✅ Lower operating temperature → More stable power output in hot climates

💡 Bifacial Technology – Enhanced Energy Production

Bifacial photovoltaic modules feature an active solar cell layer on both the front and rear sides, allowing for light absorption from both surfaces. Instead of a traditional protective backsheet, they utilize transparent tempered glass, enabling the use of reflected light from the ground.

With a bifaciality factor of >80%, the SUNPRO 580W Silver module increases total energy output, offering the following benefits:

🔹 Higher energy yields without requiring additional space
🔹 Enhanced performance on cloudy days and during winter months
🔹 Greater mechanical durability due to glass-glass construction
