SOLIX PS400 Solar Panel with Adjustable Kickstand, 400W Foldable Portable Solar Charger, IP67 Waterproof, Smart Sunlight Alignment, for Camping, RVs, and Blackouts

It’s big, not the easiest to handle and place. However it was kicking out around 300w in full sun. It’s just difficult to reposition as the sun moves

I put these on two rails, then mounted them to my roof, kinda a test. They have passed for QUALITY, DURABILITY, FUNCTIONALITY, and price.

These flexible solar panels are absolutely fantastic. They are the backbone and heart of my entire Anker Solix battery bank electrical system in an extremely remote off-grid location. I literally depend on them for my daily life, and they deliver reliably every single day. The build quality is outstanding, and they handle harsh conditions without missing a beat. If you need dependable solar power in the wilderness, these are the panels to get.

Anker's panels are way overpriced. This panel is also huge/heavy and takes up a lot of space to set up.

The only thing about these that’s a little disappointing is the snaps. They are nearly impossible to unsnap. I have 6 of these and get very good results. A little heavy and much easier to set up with 2 people, they do work well. Easy to store and the adjustments using a sunshine target spotter attached to them is all it takes to maximize PV. Counting line loss- I’m happy with the wattage results.

( 2 of these 35lbs. 400w panels (70lbs) and a 767 Powerhouse 70lbs. ) you can power any campsite. Have a gas generator too? Even more Day power. If you just need the solar panels for your set up, they seem like they just need to be mounted, but could be taken if needed. But they are heavy, bulky, nice build quality but I wouldn’t aim to be rough on them. Was getting peak sun/uv index and no clouds, good heat so with all that 2x 400w panels 275w from each. 550w. Obviously not the full 400w but still nice for free portable power
