EcoFlow 220 Watt Portable Bifacial Solar Panel

The EcoFlow 220W Bifacial Solar Panel charges power stations and off-grid batteries using sunlight. This 220 W panel uses a dual-sided design to capture direct sunlight and ambient light reflection. It employs monocrystalline silicon cells to convert solar radiation into DC power with a rated efficiency of 25%, making it suitable for outdoor or emergency use.

The foldable design allows the panel to pack down to 571 × 600 × 32 mm for transport. With an IP68 rating, the unit is water-resistant and suited to varied outdoor conditions. The panel weighs 9.96 kg and includes a 1.5 m cable for connecting to a power source. It uses standard MC4 connectors to integrate with most EcoFlow power stations, and an integrated kickstand allows users to adjust the angle for optimal sun exposure. The unit has a power tolerance of 2.27%.

• Voltage at maximum power (Vmp): 18.4 V; Current at maximum power (Imp): 11.9 A.
• Open-circuit voltage (Voc): 21.5 V; Short-circuit current (Isc): 12.4 A; ensures compatibility with power stations requiring low-voltage DC input.
• Temperature coefficient of Voc: -0.25 %/°C; minimises voltage drops as the panel temperature increases.
• Operating temperature range: -20 to 85 °C; maintains functionality in extreme cold and high heat.
• Unfolded width: 2123 mm; provides a wide surface area for light capture.
• Temperature coefficient of Isc: 0.045 %/°C; ensures stable current levels as cells heat up.
