EcoFlow 220W Bifacial Solar Panel – Dual-Side Power, 23% Efficiency

EcoFlow 220W Bifacial Solar Panel – Dual-Surface Power, 22.6% Efficiency, IP68

EcoFlow’s 220W Bifacial Panel represents a leap forward in solar panel technology — capturing sunlight from both the front and rear surfaces for up to 25% more energy generation compared to traditional single-sided panels. Its 22.6% conversion efficiency and IP68 waterproof rating make it the go-to premium panel for EcoFlow DELTA and RIVER power station owners who want maximum charging speed from the fewest panels.

• Bifacial Cell Technology: Captures direct sunlight on the front and reflected/diffuse light on the rear — generates up to 25% more power than conventional single-sided panels in the same space
• 22.6% High Efficiency: Industry-leading efficiency for a mass-market rigid panel; generates more power per square foot than nearly any other consumer solar panel available
• IP68 Fully Waterproof: Highest waterproof rating available for rigid panels — survives heavy rain, hosing, flooding, and wet installation environments without degradation
• EcoFlow Power Station Optimized: Directly compatible with EcoFlow DELTA 2, DELTA Pro 3, DELTA Max, and RIVER 2 Pro via included XT60 and Anderson connectors
• Rigid Aluminum Frame: Heavy-duty anodized aluminum frame with pre-drilled mounting points; rated for 5,400 Pa snow load and 2,400 Pa wind for permanent rooftop or ground mounting
• 22-Year Efficiency Warranty: EcoFlow backs each panel with a 22-year linear power output warranty guaranteeing minimum 80% output after 22 years of outdoor use
• Low Temperature Coefficient: Better performance in cold weather compared to standard cells; -0.29%/C coefficient maintains output in cooler climates and during winter months
