✓Higher Conversion Rate：The regular convex points of surface distribution are conducive to the secondary propagation of light, absorb the radiant heat of solar energy to a greater extent, and greatly improve the photoelectric conversion efficiency
✓Widely Used：The included 3-piece SAE cable kit is plug-and-play,it can be used for cars and 12V batteries. Comes with carabiner and suction cup to meet your different installation needs. Suitable for automobiles, RVs, motorcycles, ships,snowmobile，etc
