Description
The Trina Solar Vertex S+ 445W photovoltaic panel utilises advanced N-Type i-TOPCon technology, delivering high efficiency and excellent performance in all conditions. Thanks to its bifacial double-glass construction, it enables additional energy generation from the rear side, increasing the system’s overall output.
With an efficiency of up to 22.5% and an extended lifespan, this model is ideal for both residential and commercial applications.
Advantages and benefits
✔️ Higher energy output
Bifacial technology allows for the capture of reflected light, offering superior efficiency compared to conventional systems.
✔️ Excellent performance in low-light conditions
High efficiency even in the morning, evening or on cloudy days.
✔️ Extreme durability
The double-glass construction reduces the risk of micro-cracks and degradation.
✔️ Low temperature coefficient (-0.29%/°C)
Lower performance losses at high temperatures.
✔️ Wide compatibility
Works perfectly with most inverters and mounting systems.
