【Solar String Lights】LED solar string lights use high-efficiency solar panels, which can convert solar energy into electrical energy and storage in the built-in battery allows the lighting to be on. About 1.8m lead cable and 8.2m lights shell (10.1m total length) wick perfectly spice up the places. 【High Quality and Conversion Rate】Our solar string lights made of monocrystalline silicon solar cells, and its photoelectric conversion efficiency is about 19%, the highest is 24%. This is the highest photoelectric conversion efficiency among all types of solar cells. Monocrystalline silicon lifespan up to 25 years. On the contrary, the photoelectric conversion rate of other polycrystalline silicon solar cells is only 【8 Light Modes】Gorgeous lighting modes including combination, fireflies flashing, waves, fading, chasing/flashing, fading slowly, twinkle/flashing and steady on, which can create different atmospheres for your life.
