Description
505W Sungrow Bifacial N-Type | SG-54TG4D Series
The bifacial SG-54TG4D module by Sungrow delivers superior performance thanks to its advanced N-Type TOPCon technology, enabling higher efficiency and lower degradation over time. With a nominal power of 505W and 22.70% efficiency, this panel is designed for residential and commercial projects requiring reliability, durability, and maximum energy output.
Thanks to its dual-glass design with a transparent encapsulant, the panel captures radiation from both sides, increasing energy production by up to 25% under optimal reflection conditions. It is also certified to withstand loads of up to 5400 Pa (front) and 2400 Pa (rear), making it a robust solution for environments with snow, wind, or dust.
KEY FEATURES
N-Type TOPCon Technology: This dual-glass bifacial module incorporates N-Type cells with advanced TOPCon technology, reducing LID/LeTID degradation, improving performance under high temperatures, and delivering higher long-term efficiency.
High Energy Yield: With a power output of 505W and 22.7% efficiency, the SG-54TG4D module is ideal for PV projects aiming to maximize energy generation per square meter, whether residential, commercial, or industrial.
High Mechanical Strength: Withstands front loads up to 5400 Pa and rear loads up to 2400 Pa, making it suitable for areas with snow, wind, or dust.
Minimal Degradation and Extended Warranties: Guarantees less than 1% degradation in the first year and a maximum of 0.4% annually over the next 29 years. Includes a 25-year product warranty and a 30-year linear performance warranty.
