Our take on the CTOLITY 400W ETFE Foldable Solar Panel

The CTOLITY foldable panel is a portable solar charger built for camping, van life and emergency backup. It uses ETFE-laminated cells on a folding frame, which resists scratches and light rain better than the PET film found on cheaper blankets. The listing's headline 400W does not match its own specs: peak power is listed at 100W, with 24.2V open circuit and 5.12A short circuit current. Buyers should treat it as a roughly 100W panel and check the label before relying on it to charge a power station.

Pros
  • ETFE surface is more durable and easier to clean than PET film
  • Folds for transport and storage
  • 20.5V Vmp suits many 12V MPPT charge controllers
  • CE and RoHS marked
  • Light enough for one person to carry at about 3.4 kg
Cons
  • Peak power is listed as 100W, not the 400W in the name
  • No charge controller or adapter cables mentioned
  • Output drops sharply in shade or partial cloud
  • Folded size and panel count are not stated
  • 4.6 kg shipping weight suggests a bulky folded package

Questions and answers

Is this really a 400W panel?
The specs list peak power at 100W, with Vmp of 20.5V and Isc of 5.12A. Those figures describe a panel of about 100W, so plan your charging around that.
What can a 100W panel like this charge?
In strong direct sun it can realistically feed a small portable power station or top up a 12V battery slowly. Expect much less on cloudy days or when angled poorly.
Do I need a charge controller?
Yes, if you connect it directly to a battery. The 24.2V open circuit voltage is too high for a bare 12V battery, so use an MPPT or PWM controller rated for the current.
Is it waterproof?
ETFE laminations handle splashes and light rain better than PET, but the junction box and connectors are the weak points. Do not submerge it or leave it out in heavy rain.
What comes in the box?
The listing does not detail included cables or adapters. Confirm with the seller that the connector type matches your power station before buying.
Where is the CTOLITY 400W ETFE Foldable Solar Panel cheapest?
At AliExpress, for $83.92, as of our latest check.
