Bifacial Portable Solar Panel 220W
- Two in one – EcoFlow’s 220W Bifacial Portable Solar Panel is two in one. With a 220W primary side and a 155W side on the back for ambient light, you can capture up to 25% more solar energy and charge your portable power station even faster. Try a mirrored surface and you can get up to 80% more energy.
- Tempered glass. Built to last The thin, one-piece tempered glass design makes it five times tougher than comparable panels, it can withstand heat up to 300°F too. Safe to say it can withstand the elements.
- Compact – Portable It’s a portable solar panel designed from the ground up to be compact. 10% smaller than comparable 220W panels, it saves space with thinner tempered glass, and less surface area required for the same input.
- More than a carry case – It comes with its own carry case so you can take it anywhere. Once you arrive at your destination, simply unfold it and use it as a kickstand to get your sun exposure just right.
- Waterproof – We’ve raised the bar with this panel. It’s completely water and dust-tight. Rain, wind, or shine, your panel is safe with an IP68 waterproof rating.

Frequently Asked Questions
Does the 220W Bifacial Solar Panel generate a full 220W of power?
In most cases, it is normal for a solar panel not to deliver its full nominal power. Some of the reasons why this happens, as well as some suggestions for getting closer to the nominal power figure, are given below.
- Light Intensity. The amount of light shining on the panel will result in fluctuations in the power output. You are more likely to achieve nominal power output figures closer to those obtained under test conditions when using the product on a clear day during the midday sun than when using the product in the morning or later in the afternoon. Weather conditions will also affect the amount of sunlight that shines on the panel. For example, you are much less likely to achieve the figures for nominal power in hazy, cloudy, or rainy conditions.
- Surface Temperature. The temperature of the solar panel surface will also affect the amount of power generated. The lower the surface temperature of the panel, the more power will be produced. For example, solar panels generate more power when used during the winter than during the summer, and this is completely normal. Solar panels generally reach temperatures close to 60°C (140°F) during summer. This reduces nominal power by 13%, despite the higher levels of light shining on the panel.
- Sunlight Angle. In optimal light conditions, the sun’s rays should remain perpendicular to the surface of the panel for best performance. Power output is only marginally impacted by sunlight hitting the panel within 10° either side of this 90° angle.
- Panel Shading. The surface of the solar panel should not be shaded during use. Shading caused by shadows, foreign objects, and glass can all greatly reduce power output.
Performance Issues Caused by Malfunctioning Panels: If the panel still isn’t generating power or its output remains far below expected nominal power figures after addressing the issues above, there may be an issue with the panel itself. Please contact Customer Support for assistance.
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 to nominal values were normally observed in the midday sun during the winter.)
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 stations 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.
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 connect 220W Bifacial Solar Panel in parallel?
Yes, but this is not recommended. 220W solar panel has 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.
