EcoFlow 520 W Rigid Solar Panel Combo, Black

The EcoFlow 2 x 520W Rigid Solar Panel kit is designed for fixed home power systems and off-grid setups. The system converts sunlight into direct current to charge power stations or battery banks. Each 520W panel uses monocrystalline silicon cells with 24.8% efficiency, providing high energy output relative to its surface area. These panels are suitable for permanent installation on balconies, flat roofs, or tiled roofs, offering sufficient energy yield for regular residential or recreational use.

The rigid panels feature a structural frame and are IP68-rated for water and dust resistance. Each unit measures 1134 x 2094 x 30 mm and weighs 24.6 kg, providing the mass required for stable, permanent outdoor mounting. They use MC4-compatible connectors, ensuring compatibility with standard solar power hardware. A 1.1 m cable is attached to each panel to simplify wiring. The panels are covered by a 10-year warranty and are designed for operation in temperatures ranging from -40 to 85 °C.

• Open-circuit voltage of 47 V and short-circuit current of 13.4 A — ensures compatibility with standard 48 V charge controllers.
• Voltage at maximum power of 40.1 V and current at maximum power of 13 A — provides stable energy delivery during peak sunlight.
• Temperature coefficient (Voc) of -0.25%/°C — reduces voltage drop as cell temperatures rise.
• Maximum system voltage of 1500 V — allows for integration into high-voltage series solar arrays.
• Power temperature coefficient of -0.3%/°C — indicates potential power output variations across different climatic conditions.
• Temperature coefficient (Isc) of 0.045%/°C — helps maintain current output in high-heat environments.
