The EcoFlow 125W Bifacial Modular Solar Panel is a portable, high-efficiency, dual-sided panel designed for flexible expansion with an adjustable tilt and durable, weatherproof construction (IP68) that connects easily to EcoFlow power stations via XT60 ports. Key features include TOPCon cell technology for improved low-light performance, a 50V design for parallel connections, and integrated kickstands for optimal sun exposure.
Key Features & Technology
- Bifacial Design: Captures light from both front and back, boosting power output (up to 138W BNPI vs. 125W STC).
- TOPCon Cells: Utilizes N-type solar cells for high conversion efficiency (up to 25%) and better performance in high temperatures and low light.
- Modular & Scalable: Allows for parallel connections of up to 8 panels for 1000W, or more complex series/parallel setups for higher wattage.
- 50V Design: Tailored for flexible parallel connections, supporting 60V and 150V energy storage systems.
- Adjustable Kickstands: Integrated stands offer 30-60° tilt for optimal sun tracking.
Durability & Portability
- IP68 Waterproof: Built tough for all-weather use with an anti-corrosive aluminum frame and durable tempered glass.
- Lightweight: Designed for portability, with individual panels weighing just 9.26 lbs (4.2 kg).
- Easy Setup: Features 3M™ Dual Lock™ fasteners for quick assembly and a protective bag for transport.
Connectivity
