That flexible panel was rated 100W when you bought it. A few seasons later it’s cloudy, yellow and making a lot less.
The fix starts before you buy: the clear top layer decides how long a flexible panel lives on a boat.
1️⃣ PET is cheap plastic that hazes and yellows in the sun
2️⃣ ETFE stays clear far longer and sheds salt and grime
3️⃣ Fiberglass composite panels stop cracked cells, the failure we see most
4️⃣ Choose by where it mounts: canvas, deck or rigid arch
Swipe for the side by side numbers.
Save this before you buy your next panel.
