The anker solix ps400 400w bifacial alternatives list helps you find other options if this panel does not fit your needs. This model offers a lightweight 21.9 lb design and dual-sided power generation. Its IP68 rating ensures protection against rain and dust. The 25%+ cell efficiency captures energy from both front and rear surfaces. These specs make it ideal for reflective environments like snow or sand.
However, you might prefer a different size, weight, or brand. Some users need higher wattage or a more compact folded footprint. This guide covers 6 alternatives chosen because their specs overlap with the original. Each option shares key features like foldable design and weather resistance. You can compare dimensions, cell types, and IP ratings to find the best fit for your RV, camping, or home backup setup.
How each alternative compares
MHPOWOS 400W Bifacial Solar Panel
The MHPOWOS 400W Bifacial Solar Panel shares the same 400W output and IP68 weather resistance as the Anker SOLIX PS400. It also uses N-Type cells for 25%+ efficiency. You will notice a difference in form factor. This panel is wider and shorter than the Anker model, measuring 34.6 inches by 26.7 inches. It weighs slightly more at 24.3 pounds. The Anker version is 10% lighter and longer. Choose the MHPOWOS if you prefer a wider footprint for stability on reflective surfaces like sand or snow. The Anker SOLIX remains the better choice for hikers who need the absolute lightest carry weight.
ALLPOWERS 400W Foldable Solar Panel
The ALLPOWERS 400W Foldable Solar Panel drops the bifacial feature found in the Anker SOLIX PS400. It relies on single-sided power generation. However, it maintains a 400W rating and includes necessary charging cables in the box. Its IP67 rating is slightly lower than the Anker’s IP68, offering less protection against dust immersion. The ALLPOWERS unit is thicker and heavier when folded, with a height of 4.72 inches compared to the Anker’s 0.67 inches. Pick this option if you want a straightforward setup with included accessories and do not need the extra energy gain from dual-sided sunlight capture. The Anker is superior for maximum efficiency in bright, reflective environments.
ZOUPW 480W Bifacial Portable Solar Panel
The ZOUPW 480W Bifacial Portable Solar Panel offers 20% more wattage than the Anker SOLIX PS400. Both use N-Type cells and carry an IP68 rating for weather resistance. The ZOUPW model is significantly larger, measuring 139 inches in length, making it less portable for solo camping trips. It weighs 22.5 pounds, which is comparable to the Anker’s 21.9 pounds. The Anker’s compact 90.2-inch length is easier to transport and store. Select the ZOUPW if you need higher power output for RV or home backup systems where size is less critical. The Anker SOLIX is better for backpacking or tight spaces where portability is the main priority.
ZOUPW 450W Bifacial Foldable Solar Panel
The ZOUPW 450W Bifacial Foldable Solar Panel provides 50W more power than the Anker SOLIX PS400. It shares the same IP68 rating and N-Type cell technology. This model is lighter at 20.9 pounds, beating the Anker’s 21.9 pounds. However, it is much longer at 121 inches, compared to the Anker’s 90.2 inches. The ZOUPW is 0.8 inches thick, while the Anker is only 0.67 inches. Choose the ZOUPW if you need the extra wattage and do not mind a longer panel. The Anker SOLIX remains the more compact option for users who prioritize ease of carrying and setup in reflective environments like snow or sand.
MHPOWOS 400W Foldable Solar Panel
The MHPOWOS 400W Foldable Solar Panel uses Monocrystalline cells instead of the N-Type cells in the Anker SOLIX PS400. It lacks bifacial capability, so it cannot capture reflected light. Its IP67 rating is slightly lower than the Anker’s IP68. This panel is heavier at 27.9 pounds and thicker at 1.1 inches. It is also shorter in length at 81.2 inches. The Anker SOLIX is lighter, thinner, and more efficient in low-light or reflective conditions. Opt for the MHPOWOS if you find it available at a better value and do not need the advanced N-Type efficiency or dual-sided power. The Anker is the better technical choice for maximum energy harvest in varied lighting.
Ecosonique 400W Foldable Solar Panel
The Ecosonique 400W Foldable Solar Panel matches the Anker SOLIX PS400 in wattage but lacks bifacial features. It uses a standard foldable design with an IP65 rating, which is lower than the Anker’s IP68. This means less protection against dust and water jets. The Ecosonique unit is 22.9 pounds, slightly heavier than the Anker’s 21.9 pounds. Its dimensions are different, with a width of 21.8 inches and length of 18.7 inches. The Anker SOLIX offers superior weather resistance and dual-sided power generation. Choose the Ecosonique if you need a basic 400W panel for dry conditions and prefer a different form factor. The Anker is better for harsh weather and high-efficiency needs.
