Why N-type bifacial panels?
Higher efficiency than standard panels Better performance in low light and high temperatures Can capture reflected light from rear side Lower degradation over time Certified for extended stress, salt mist, and ammonia corrosion N-type bifacial panels are popular because they combine the superior performance of N-type silicon (higher efficiency, less degradation from light, better heat tolerance) with the dual-sided energy capture of bifacial design, resulting in significantly higher overall energy yield, longer lifespan, and better reliability, especially in diverse conditions, making them a powerful upgrade over traditional P-type monofacial panels.
