Anker SOLIX PS400 Bifacial Portable Solar Panel

- 400W bifacial, N-type 25%+
- 22 lbs with stand
- IP68, 5-year warranty
Our take
A high-output, light 400W panel for RVers with a big station.
Why it made the shortlist
The Anker SOLIX PS400 is a 400W bifacial foldable panel that weighs 22 lbs with its stand, about 10% lighter than the previous version. N-type cells rated 25% or higher, a dual-sided output claim of up to 10% more power and IP68 protection come with a five-year warranty.
It offers lower rated output than the 480W ZOUPW and a lower listed bifacial gain, in exchange for a named warranty and a lighter build. Against the Renogy 200W it doubles the output.
It suits RV owners who recharge a large power station from a parked rig. The box includes two 8.2 ft cables and a 1.6 ft XT-60i lead.
What works
- High 400W output from one panel
- Light for its size at 22 lbs
- Dual-sided power generation
Watch out for
- Priciest tier of this list
- Large panel needs space
- The catch
- Bifacial gain depends on reflective ground such as snow or light concrete.
