An 85W, 3 mm flexible panel for RVs, boats and roof tents
Lensun's 85W black flexible panel is a 12V panel for RVs, campers, boats and roof tents. Back-contact (BC) cells with no front gridlines are rated up to 25.8% efficiency under a self-cleaning ETFE film, and a twin-array layout keeps it producing when part of the panel is shaded.
It is only 3 mm (0.12 in) thick, weighs 2.9 lb (1.3 kg) and measures 39.4 × 16.3 in. Fix it with adhesive, zip ties or Velcro, without structural roof reinforcement; it comes with a 3.3 ft (1 m) cable.

Questions about the Lensun 85W 12V Black Flexible Solar Panel
Answers from Lensun Solar's published product information.
What warranty comes with Lensun flexible and hood panels?
Lensun covers its products with a 24-month (2-year) workmanship warranty for the original buyer. Lensun also rates its solar cells to produce at least 90% of nominal power after 10 years and 80% after 25 years.
How is a flexible panel mounted?
Lensun recommends bonding the back of the panel with a silicone structural adhesive such as Sikaflex 252. On a hood, Lensun highly recommends its custom vinyl decal between the panel and the paint to protect the finish.
Will it work on cloudy days?
Yes, but it produces less. Lensun says a panel under a light overcast sky may produce about half as much as in full sun.
Why does shade matter so much?
The cells in a panel are wired together, so every cell needs full sun for the panel to work at its best. If any part of the panel is shaded, the output of the whole panel drops.
Can I walk on a flexible panel?
Lensun doesn't recommend it. Walking on the panel can damage the cells and solder joints inside.
