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.
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.
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 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.
