Durable & High Temperature Resistance

imported ETFE material on surface; High-temperature resistance


Black/White Flexible Solar Panel

- Better heat resistance to keep efficiency
- Weak light tolerance to work well under the weak light

Resistance to the lightly cracked cells
Ultra-light, ETFE surface, high-temperature resistance, corrosion resistance, and water resistance
- Available to be bent 30 degrees, great for RVs, cars, boats and some irregular surfaces



Ultra-thin, Lightweight, Aesthetic and Flexible Solar Panel

SP flexible solar panel uses back contact SunPower solar cell, with efficiency from 22.4% to 23.6%. Japan-imported ETFE materials allow the solar panels to resist high temperatures at 242℃, and their transmittance is over 95%. Moreover, it features excellent waterproof performance.


SP series is more flexible than conventional flexible solar panels like FP series, since it can bend 30° at maximum. It’s an aerodynamic design that can reduce wind resistance when installing on the rooftop of RV or yacht.
