EcoFlow 220W Bifacial Solar Panel Review: More Power From Both Sides

EcoFlow’s 220W Bifacial Solar Panel is one of the most innovative portable panels we’ve tested. By using N-type monocrystalline cells on both sides, it captures reflected light from the ground beneath it — delivering real-world gains of 10-25% more energy depending on the surface.

Key Specs at a Glance

• Wattage: 220W (rated)
• Efficiency: 23% conversion rate
• Weight: 20.7 lbs
• Waterproof Rating: IP68
• Connector: XT60 (MC4 adapter included)

Who Is It For?

This panel is ideal for anyone who wants maximum solar output from a single portable panel. It pairs perfectly with EcoFlow DELTA and RIVER series power stations, and the MC4 adapter makes it compatible with other brands too. Best for car camping, RV setups, and off-grid projects where you have a reflective surface underneath.

The Bifacial Advantage

Traditional solar panels only capture light hitting the front face. The EcoFlow 220W has solar cells on both sides. When placed on a light-colored surface — concrete, snow, sand, or a reflective ground sheet — the rear cells capture bounced light for extra energy.

In our testing on a light gravel surface, we measured roughly 15% more output compared to a similar single-sided panel. On a white ground sheet, that jumped to about 22%. On dark grass or dirt, the bifacial gain was minimal (5-8%), so the surface matters.

Build Quality and Design

The panel feels premium. The IP68 waterproof rating means it can handle rain, dust, and even brief submersion — a step above most competitors’ IP65 ratings. The built-in kickstand is sturdy and adjustable, letting you dial in the optimal angle without any extra gear.

At 20.7 lbs, it’s heavier than 200W alternatives from Jackery (17.6 lbs) and Bluetti (16.1 lbs). The extra weight comes from the dual-sided cell construction and the robust kickstand mechanism. If weight is your top priority, look at the Bluetti PV200 instead.

Real-World Performance

We paired the panel with an EcoFlow DELTA 3 Plus over a week of testing:

• Full sun, clear day: 185-210W output (front only)
• Full sun with reflective ground sheet: 220-245W output (bifacial gain)
• Partly cloudy: 90-140W output
• Heavy overcast: 40-60W output

The panel charged the DELTA 3 Plus (1,024Wh) from 0 to 100% in about 5.5 hours of good sun — faster with the bifacial boost on a reflective surface.

Compatibility

The panel uses an XT60 connector natively, which plugs directly into EcoFlow power stations. An MC4 adapter is included in the box for use with other brands. We confirmed compatibility with Bluetti, Jackery (via adapter), and generic solar charge controllers.

How It Compares

Spec	EcoFlow 220W Bifacial	Jackery SolarSaga 200W	Bluetti PV200
Wattage	220W	200W	200W
Efficiency	23%	24.3%	23.4%
Weight	20.7 lbs	17.6 lbs	16.1 lbs
Waterproofing	IP68	IP67	IP65
Price	$449	$499	$399

The Bottom Line

The EcoFlow 220W Bifacial Solar Panel delivers the most real-world wattage of any portable panel in this class — especially if you use a reflective ground surface. The IP68 rating and built-in kickstand add genuine convenience. It’s heavier and pricier than single-sided alternatives, but the extra output justifies it for serious solar users.

Best for: Campers and off-gridders who want maximum solar output and can take advantage of the bifacial design with a reflective surface.
