Certified for quality and safety: BABT 8515 R37
Bifacial Technology – Harness More Energy
With its dual-glass construction, this panel is engineered to capture sunlight from both sides, increasing power generation. The rear side alone can generate up to 90W from reflected light, bringing the total peak output to 530W when mounted on a reflective surface. Whether for off-grid, hybrid, residential, or large-scale utility installations, this panel adapts seamlessly to various applications. Optimal performance is achieved when installed at an angle using a triangular frame, allowing the rear to absorb maximum reflected sunlight.
Superior Efficiency & Long-Term Performance
- High power output of 440W with an industry-leading module efficiency of 22%, ensuring optimal energy conversion.
- N-Type bifacial technology increases energy yield by capturing sunlight from both sides of the panel.
- A 30-year linear power output warranty guarantees reliable performance and long-term investment protection.
Versatility for Diverse Applications
- Designed to support system voltages up to 1500V, making it suitable for residential, commercial, and large-scale installations.
- Perfect for installations with reflective surfaces, maximising energy capture and efficiency.
Built to Withstand Harsh Weather Conditions
- Engineered for extreme environments with a snow load capacity of 5400 Pa and wind resistance up to 2400 Pa.
- Designed for durability, weighing 22kg with compact dimensions of 1762mm × 1134mm × 30mm, making handling and installation easier.
Seamless & Secure Installation
- Stäubli MC4-EVO2 connectors ensure a reliable and hassle-free electrical connection.
- Equipped with pre-fitted cables – 300mm positive and 400mm negative – for greater flexibility during setup.
