EcoFlow 220W Bifacial Solar Panel

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.)

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.

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.

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.

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.

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.
