Main highlights

Max To 270° Flexible. Matches more curved surfaces, allowing you to install where rigid solar panels cannot. Make full use of the limited space on the roof or even the curved part of the front of the car.

ETFE Covering Material. Using ETFE instead of PET, will not delaminate after long-term use, so it has a longer service life. It has anti-scratch/self-cleaning/sand-proof capabilities and can resist impact and abrasion, preventing collisions and possible wear, scratches, etc. This happens frequently during transportation and maintenance activities.

Double Fiberglass Protect increases the impact resistance. No worry about the crack. Double glass fiber is placed on the upper and lower layers of the mono solar cell for protection, which can avoid damage to the mono solar cell to the greatest extent.
