Dimple technology captures more light at the panels surface than PET Sewn panels, it´s dustproof and is a high conversion solar charging technology, keeps your device powered up with free solar power.
 It is portable and convenient to carry while hiking, camping, traveling and doing any other outdoor trips and activities. ETFE laminated panels are lighter and thinner than PET Sewn panels.

ETFE Lamination panels do not reflect the light. They absorb sunlight and increase the solar absorption rate by 5%. PET sewn panels reflect a large amount of sunlight, producing glare and creating a traffic risk to cars and airplanes.

The use of high frequency thermal welded construction means that the solar cells are better protected from water and dust than traditional sewn folding panels.  ETFE laminated technology panels are more waterproof and more corrosion resistant. Sewn PET is only water resistance but it is not waterproof.
