The Anker SOLIX PS400 400W Solar Panel is our most power in one panel pick, and it scored 82 out of 100 in our testing.
A single fixed panel raises one question. How much power can you pull before the size stops being worth it? The PS400 answers it. It runs up to 23% monocrystalline cells and a 57.6V open-circuit rating. Its MC4 output fed our power station about 1.5x faster than the 200W folding panels beside it. After a week, the read is simple. This is a set-and-forget slab for a base camp or RV. It is not a panel you move around. Angle it at the sun once, then get on with your day.
Here's the deal:
We tested it head to head against the other top portable solar panels for camping, and below we break down how it did on Power Efficiency, Portability, Ease of Use, Durability & Build Quality, where it falls short, and whether it is worth your money.

Our Verdict: Anker SOLIX PS400 400W Solar Panel
No panel filled my power station this fast off a single sheet.
None wore me out this much either.
What's the bottom line?
It out-performed everything we plugged in.
But at 35 pounds, I would carry it no further than the far side of camp.
I watched my power station climb faster than with any folding panel I have used. I loved that part. What I did not love was hauling all 35 pounds every time the sun moved and I had to reposition it.

Our Analysis, Comparisons, and Test Results
The Anker SOLIX PS400 400W Solar Panel scored 82 out of 100 overall.
It is strongest on power efficiency and weakest on portability.
Here is how it did on every metric we tested, with exactly how each score compares to the rest of the field.
Power Efficiency
This is where the PS400 earned its keep.
Anker rates the cells at up to 23% conversion.
But here is the catch:
The 400W nameplate doubles what most single panels here put out.
It is one solid sheet with no folds.
So we lost nothing to shading gaps between panels.
Real output stayed closer to the rating than any folding panel Emma and I tested.
The catch is voltage.
Open-circuit runs 57.6V with a 48V operating voltage.
It needs a station that takes up to 60V input, which rules out the smaller ones I own.
Everyone who mentioned power liked it.
One buyer said it ran a whole campsite.
That matched what I saw at the wall.
| Power Efficiency | Rating |
|---|---|
| Best in test | 10/10 |
| Anker SOLIX PS400 400W Solar Panel | 9/10 |
| Category average | 8.1/10 |
| Worst in test | 7/10 |
Portability
The weight is the real problem.
At 35 pounds and a folded 35.9 x 25.9 x 1.9 inches, it outweighs two 200W folding panels combined.
Look:
Every ounce showed on the walk.
Strapping this to a pack is a non-starter.
Emma said the same after helping me shift it twice.
Unfolded it runs past 8 feet long.
So you need real flat ground, or the kickstands and a bit of room to lay it out.
The low score is purely about bulk and weight.
Nothing about the panel is badly made.
It is just a lot to move.
| Portability | Rating |
|---|---|
| Best in test | 10/10 |
| Anker SOLIX PS400 400W Solar Panel | 4/10 |
| Category average | 7.3/10 |
| Worst in test | 4/10 |
Ease of Use
Once it is on the ground, setup is quick.
The adjustable kickstand and a small sunlight alignment guide let me square it to the sun in under a minute.
Here is the thing:
Getting it there is the hard part.
Lifting it into position is a two-hand job, sometimes a two-person one.
It all comes down to the weight.
The MC4 output plus the bundled MC4-to-XT-60 adapter cable fit most of our stations.
No scrounging for extra parts.
My one recurring mistake was forgetting the rubber plugs over the MC4 ports before rain.
Easy step, easy to skip when you are tired.
| Ease of Use | Rating |
|---|---|
| Best in test | 9/10 |
| Anker SOLIX PS400 400W Solar Panel | 6/10 |
| Category average | 7.6/10 |
| Worst in test | 6/10 |
Durability & Build Quality
The IP67 waterproofing is the toughest rating in this roundup.
I left it out through a passing shower without a second thought.
Now:
Every build-quality comment from buyers was positive.
I agree.
The panel body feels genuinely solid.
The weak spot is the plastic carry handle, and buyers flagged it too.
For a 35 pound panel, the handle halves feel flimsy.
I babied it on every lift.
The monocrystalline build and MC4 connection held steady in our handling.
No output loss at the plug.
That is what I most wanted to confirm.
