Trina Solar's Vertex N series is a high-efficiency photovoltaic module developed based on n-type i-TOPCon technology and a 210mm silicon wafer platform. It features high efficiency (e.g., the 720W+ module achieves 23.2% efficiency), low system costs (optimizing BOS costs and logistics efficiency), and full-scenario adaptability (suitable for ground power stations, residential use, and complex terrains). With bifacial power generation, low attenuation rates, and low-carbon design (carbon footprint as low as 400kg/kW), the series significantly reduces LCOE and drives the industry toward the 700W+ high-power era, making it a benchmark product for photovoltaic technology upgrades and sustainable energy development.
