Solar panels that use nanotechnology have a very thin layer of nanoparticles that absorb sunlight and convert it into electricity. They are different from non-nano counterparts in that they are more efficient in converting sunlight into electricity, they are more flexible, and they are more durable. Non-nano solar panels are generally thicker and are made of a different type of material that absorbs sunlight and converts it into electricity. They are less efficient than nanotechnology-based solar panels.
