EcoFlow 220W Bifacial Portable Solar Panel
The EcoFlow 220W Bifacial Portable Solar Panel delivers advanced solar technology with dual-sided energy capture. This portable solar panel features a 220W primary side and 155W rear side, allowing you to harness up to 25% more solar energy from ambient light. When paired with a reflective surface, energy capture increases up to 80%.

Bifacial Design for Maximum Power Output
The two-in-one bifacial design separates this panel from standard solar panels. With monocrystalline silicon cells achieving 22-23% conversion efficiency, you get optimal power generation in a compact form. The panel measures 10% smaller than comparable 220W panels while maintaining full power output.

Tempered Glass Construction
Built with one-piece tempered glass, this solar panel is five times tougher than standard panels. The glass withstands temperatures up to 300°F and provides superior durability for outdoor use. At 9.5kg (20.9lbs), the panel balances portability with robust construction.

IP68 Waterproof Rating
The IP68 waterproof rating ensures complete protection against water and dust. This portable solar panel operates reliably in rain, wind, or shine, making it suitable for camping, RV use, off-grid living, and emergency backup power situations.

Integrated Carry Case and Kickstand
The included carry case doubles as an adjustable kickstand, allowing precise angle positioning for maximum sunlight exposure. The self-supporting design eliminates the need for additional mounting equipment, making setup quick and convenient wherever you need power.

Technical Specifications
The panel outputs 21.8V open circuit voltage (18.4V Vmp) with 13A short circuit current on the front side and 8.8A on the rear. MC4 standard connectors ensure compatibility with EcoFlow DELTA and RIVER series power stations, as well as other MC4-compatible portable power stations.

FAQS
Can I connect 220W Bifacial Solar Panel in Parallel?
Yes, but this is not recommended. 220W solar panel have a maximum current rating of 12A. Though these panels can be connected in parallel, DELTA and RIVER series power stations only support a maximum current of 12A. Parallel connections increase power output by doubling the current, but connecting the panels in this way would result in a 1+1=1 scenario whereby the current is limited to 12A by the connected devices. We do not recommend connecting the panels in parallel, unless you use a different brand of power station with an input current of 20A or above.
Can I connect both 110W and 220W Bifacial Solar Panels together in Series?
Yes, but this is not recommended. While the voltages of the two panels are identical, the current ratings are not. This means that when the panels are connected in series, the current will be limited to that of the 110W panel and the full performance potential of the 220W panel cannot be released, resulting in a 1+2<3 scenario. Please purchase panels of the same size if you intend to connect multiple panels in series.
Can I use non-EcoFlow branded power stations with the 220W Bifacial Solar Panel?
Yes, but only certain types. The power station used must be compatible with MC4 standards in order to work properly. In addition, other brands of power station may not offer the same levels of compatibility as EcoFlow-branded power stations, may have lower nominal power ratings, and may not offer the same levels of performance.
The 220W Bifacial Solar Panel has two sides. How can I tell which side is which, and how can I optimize power generation using the rear side of the panel?
The front side of the Bifacial Solar Panel has a junction box. This side of the panel generates power by being positioned perpendicular to the sun's rays. Since the rear side of the panel faces away from the sun, it does not generate electricity in the usual way. Generally speaking, the rear of the panel uses ambient light to increase the overall performance of the product by up to 5%-25%. This figure is higher if mirrors are used, or when ambient light levels are high. Using the product with the rear side of the panel facing the sun generates 80% of the power when compared to using the front side. Using the panel in this way does not have a negative effect on the product.
How much power can the 220W Bifacial Solar Panel generate under normal conditions?
This depends first and foremost on weather conditions. Generally speaking, on a clear day with no clouds in the sky, sunlight hitting the panel at a 90° angle usually generates 160W–180W of power in the 220W panel. (Current light conditions are normally 800W–900W/m2 (74.3W–83.6W/ft2) with a panel temperature of 50°C (122°F) under test conditions. Nominal power ratings are based on 1000W/m2 (92.9W/ft2) in AM1.5 conditions with a panel temperature of 25°C (77°F) under test conditions. Power output figures close nominal values were normally observed in the midday sun during the winter.)
What should I know about the operating temperature, storage, and use of the 200W Bifacial Solar Panel?
The operating temperature of the Bifacial Solar Panel is -20°C–85°C (-4°F–185°F). The panel should be folded into its original shape and stored in its Protective Case (Kickstand), which provides sufficient protection for the product. To extend the service life of the panel, ensure that the product is not exposed to external forces/impacts when not in use. The solar panel itself is made of glass and must not be dropped, pierced, bent, or sat on. These actions may break the glass and render the panel unusable. Any such damage will not be covered by the free warranty.
