EcoFlow 220W Bifacial Portable Solar Panel (SOLAR220W)
This bifacial monocrystalline solar panel delivers powerful dual-sided energy capture, with 220W output on the front side and up to 155W on the rear side when exposed to reflected or indirect sunlight. Its high 22–23% efficiency ensures strong performance even in variable lighting, making it suitable for both home backup systems and outdoor off-grid setups.
Measuring 82 × 183 × 2.5 cm, it provides a large surface area for optimal solar absorption while maintaining a slim profile for easy mounting. The panel features an open-circuit voltage of 21.8V and provides up to 13A short-circuit current on the front side (12.0A operating current), with the rear side generating up to 8.8A short-circuit current (8.4A operating). Weighing approximately 9.5kg (20.9 lbs), it balances durability with portability. Built using high-grade monocrystalline silicon cells, this panel offers stable output and long-term reliability for solar generators, RVs, homesteads, and mobile power solutions.

FAQ
Q1: What makes a bifacial solar panel different?
A bifacial panel generates power from both the front and the rear side, capturing reflected sunlight to increase total power output.
Q2: Does the rear side always produce 155W?
No—rear output depends on environment. Bright surfaces (sand, tiles, concrete) increase reflection and improve rear performance.
Q3: Can it work with portable power stations?
Yes—just ensure you use a compatible solar charge controller or correct voltage input range.
Q4: Is it suitable for rooftop or RV mounting?
Yes—its slim and durable structure makes it suitable for rooftops, RVs, and off-grid outdoor setups.
Q5: Does weather affect performance?
Like all solar panels, output varies with sunlight—but its high efficiency helps maintain strong performance even in cloudy or low-light conditions.
